FACTfile - Fiat Punto

When we received the press release about the new Fiat Punto we thought for a split second that Ateco were announcing the return of Fiat to the Australian market - but then we realised it was a combination of wishful thinking and a typo. Still the brand is still available in New Zealand - and for the benefit of Fiat fans in Australia we are giving you the full details on the new Fiat Punto direct from the importer Ateco:

THE NEW FIAT PUNTO ARRIVES IN NEW ZEALAND
" New 1.4 litre engine for the Punto Sporting
" New exterior and interior styling
" New equipment and features

The new Fiat Punto has arrived in Australia (see above), offering a new 1.4 litre engine with more power and torque, new styling inside and out and a host of new equipment and features that refine and enhance Fiat's top selling model.

"The Fiat Punto is the very definition of what has made Fiat such a byword for small cars," says Chris Burger, General Manager for Fiat in New Zealand. "It is a stylish, character-filled small car that is both great fun to use and practical in every sense of the word, with loads of space inside, flexible seating, excellent economy and a high level of standard equipment. Like every small Fiat that has gone before it, the Punto is living proof that small cars don't have to be dull appliances!"

The new Punto is immediately recognizable from the outside thanks to its new nose, which features new, more powerful headlights and two new grilles, one for the HLX versions and a new honeycomb grille in the bumper and front splitter for the Punto Sporting. The key changes at the rear of the new Punto revolve around the bumper, simplified and more stylish for the five door versions, larger, more aggressive and fitted with honeycomb black mesh to match the front of the Punto Sporting.

But the changes are much more than skin deep. The Punto Sporting now has a new 1.4 litre engine that lifts power from 59 to 70 kW and torque from 114 to 128 Nm, which, combined with the standard six speed manual gearbox provides excellent performance. The dash to 100 kmh now takes just 9.6 seconds, while top speed, where the law permits, is 178 kmh, making the Punto Sporting a veritable pocket-rocket.

A range of technical improvements to Fiat's 1.2 litre 16 valve power unit in the Punto HLX enhances refinement and lifts performance and responsiveness so that these versions offer a top speed of 172 kmh and an acceleration figure 11.4 seconds for of 0 to 100 kmh.

Changes to the suspension, including a new, extra-rigid torsion beam increases vehicle stability in all driving conditions, while work has been completed that results in a quieter, smoother ride with reductions in noise and vibration transmission. New technical equipment in the Punto Sporting includes the Electronic Stability Programme (ESP) with Hill Holder in the standard ABS system that stops the car rolling back in hill starts. ESP adds an electronic safety net for the driver in extreme conditions.

All versions of the new Fiat Punto are well equipped, with twin front air bags, remote central locking, Fiat Code immobilizer, climate control air conditioning, dual drive electric power steering, front electric windows, follow-me-home lights, delay action interior lighting, remote tail gate release, split fold rear seats, digital audio CD system and front foglights all standard. The Punto Sporting adds to this comprehensive package alloy wheels, leather steering wheel, deep set front and rear bumpers with honeycomb mesh, side skirts and spoiler and sports upholstery.

The Fiat Punto HLX manual has a recommended retail price of $22,990, while the HLX version with Fiat's advanced Speedgear CVT automatic gearbox with six speeds is available for $25,990. Topping the new Punto range, the Punto Sporting now costs $25,990.

"The Punto has proven to be another highly successful small car for Fiat, selling more than half a million cars a year, every year since its launch," says Chris Burger. "The new Punto takes everything that has made that level of success possible and enhances it, confirming the Punto as another great small car from the company who's name is a byword for small cars."


The new Fiat Punto Style

Exterior
The new Fiat Punto features a brand new front end that is the same for 3- and 5-door versions but differs according to the specification: more refined for elegant specifications and more aggressive for sporty version. Examples include different grilles that are now larger in size: the grille designed for elegant versions features chrome inserts while sports versions offer square ellipsoid holes. The holes are arranged in a spoked formation and frame the round Fiat logo.

Sports versions boast a dynamic front that owes its go-getting appearance to three air intakes with honeycomb grilles on the bumpers. These are highlighted by delimiting lengthways motifs. The elegant versions are distinguished by a front end that softens the aggressive feel of the previous model and considerably increases its sophistication. The change is wrought by new headlights with split reflectors that increase brightness and which have all-chrome cylindrical mounts. Their look of precious objects is enhanced by their transparency, the great care that has gone into defining the tiniest detail and the studied contrast between chrome parts and shaded parts (the shade serves to highlight the chrome). These light clusters (where nothing is hidden, everything can be seen) are the distinctive feature of the New Fiat Punto's front end.

The bumpers, also new, are bigger and house new circular polyelliptical foglights. Much may have changed at the front, but the New Punto still retains the much-praised sides of the original model diversified into 3- and 5-door versions. The Sporting also offers brand-new alloy wheels.

The side view of both cars is based on the stylistic approach of a full volume scored along the sides by two grooves of great visual impact. These distinctive motifs originate on the wing, run along the glazed surfaces to tail off at the rear.

On the 3-door model, the first part of the line is the same but it then rises toward the tail of the car to lighten and reduce the ratio between glass and metal in favour of metal. The side slash forms a pair with the upper score that tends to drop down and converge with the lower line to create a visual sensation of the car's weight being thrust forward. The rake of the rear end of the car also reinforces this impression.

On the 5-door version, the lower line does not rise toward the tail and thus makes the side look more linear. The upper mark runs cleanly along the side without dropping and apparently converges on an imaginary point outside the car. This device suggests a longer car with a greater volume. The styling strategy also allows the 5-door version to increase the area of glass at the rear. Both versions share interplay of light and shade (conferred by the meeting of different planes) that conveys an idea of the car's compactness and solidity.

The Fiat Style Centre has come up with three configurations for the rear of the new Punto. The first offers new tail-lights that extend to the boot lid on three door versions in the Sporting. These light clusters combine technology and design to give the car a more up-to-date and original look.
The second solution applies to elegant specifications five door that feature a new rear bumper with reflectors. The appearance is of greater refinement and uncluttered form.

Lastly, a rear bumper designed exclusively for the Sporting. To match the front end, this part of the car includes air intake openings with honeycomb grille air intakes. The feel of sportiness and dynamism is very strong, though the sense of class that typifies the New Fiat Punto remains unchanged. The rear bumpers can house parking sensors that are body-coloured on sports versions.

Interiors
While personality is the term that best encapsulates the exterior shape of the New Fiat Punto, the term that best sums up the nature of the interior is functionality. Whichever version is chosen, the passenger compartment always meets the needs of customers who demand a comfortable environment, user-friendliness, controls that are easy and intuitive to use and plenty of space.

As far as space was concerned, the brief was to keep the same competitive edge the previous Punto enjoyed over its rivals: i.e. the best passenger room levels in the segment. The aim was achieved and more because the volumes and spaces are cleverly managed on this model to meet motorists' true needs.

The interior of the new model ensures the same travelling comfort and practicality of use on all versions and specifications. As far as style alone is concerned, the most distinctive feature is a generous curved facia with no sharp edges that gives the passenger compartment a welcoming, reassuring look. The upper part is dark grey while the lower part is an up-to-date, sophisticated light grey. In the Sporting it comes in a uniform dark grey to emphasise the tall, high-tech look of the aluminium-coloured central console.

All the features and parts that can improve quality of life on board are arrayed on the facia. Many of these have previously only been seen on higher segment cars: an instrument panel with multifunction display, dual zone climate control system, etc. The New Fiat Punto also adds 6 keys on the steering wheel for controlling the radio.

The colours and part surface treatments have also been picked to convey pleasurable sensations to the sight and touch. A light shade has been chosen for the passenger compartment to make it look big and airy. Other surfaces feature different types of embossing to emphasise the car's refinement - e.g. the upper part of the facia - or its practicality, as in the case of the oddments compartments where the treatment also serves as scratch proofing. An opaque finish has also been applied to the plastics to ensure the various parts are a pleasure to touch and behold.

The new Fiat Punto introduces new cloths and brand-new pale colours for the trims that make the passenger compartment look even more elegant and refined.

The control panel is also new. This part differs from specification to specification and offers fully redesigned graphics and all-new displays. The displays also offer a greater number of functions and rows to convey information to the driver more effectively.


The new Punto's Engines

The new 1.4 16v Fire engine
The new engine 1.4 litre Fire engine in the Punto Sporting has a cylinder capacity of 1368 cc and a 4 cylinder in line configuration with bore of 72 millimetres and stroke of 84 mm. The four valves per cylinder are driven directly by two overhead camshafts.

The power unit was developed with particular attention to performance and fuel consumption, an area where the New Fiat Punto excels in its category. This is due to the fact that the volumetric efficiency has been optimised throughout the service range due to painstaking fluid dynamic development studies on the entire intake and timing system. The result is a power output of 70 kW (95 bhp) at 5800 rpm and a maximum torque of 128 Nm at 4500 rpm. A New Fiat Punto equipped with this engine reaches 178 kmh top speed, accelerates from 0 to 100 kmh in 9.6 and covers a kilometre from a standing start in 31.7 seconds. The fuel consumption figures are amongst the best in the segment: 8.8 l/100 km over an urban cycle, 5.3 l/100 km for an extra-urban cycle and 6.6 l/100 km over mixed routes.

In other words, a vigorous yet frugal engine. This performance is aided by an electronic throttle valve control system known as a drive by wire system. Unlike the current production 16 valve unit, the 70 kW 1.4 unit uses new engine control unit management software.

This torque-based system represents the cutting edge in its field. Its strength lies in being able to manage all actions through a single co-ordinator block that operates according to one basic parameter, i.e. the driver's torque requirements expressed through the accelerator. When translated into a physical torque value, these demands (including the demands of external systems such as the ABS) may be coordinated even before the main engine control parameters have been converted (advance, throttle position, injection time etc.) with the huge benefit of meeting the needs with extraordinary accuracy and within a very short time period. Not to mention the fact that this system exploits a single standard of communication between the various systems and functions that all speak the lingua franca of drive torque. This allows a higher level of handling than with current systems while also reducing polluting emissions levels. The system also guarantees maximum integration with all the other devices such as ESP.

Another specific feature of the new 70 kW 1.4 16v Fire engine is the increase in compression ratio and the high torque values at low speeds, qualities that have allowed fuel consumption to be kept low. This aim is also achieved through the tuning of the cutting edge engine control system that succeeds in cutting fuel consumption as far as possible while still maintaining handling, performance and low emissions. The 70 kW 1.4 16v already meets Euro 4 legislative requirements due to a catalytic converter located in the engine compartment, welded to the exhaust emission manifold flange using a new method and which reaches high temperatures within a shorter time period and thus reduces emissions even during the power unit heating stage. To minimise the emissions effect, the new engine is also equipped with a no-return fuel system that eliminates fuel recirculation within the tank and thus reduces vapour formation.

High-performing, thrifty and clean: the 70 kW 1.4 16v Fire unit backs these qualities with outstanding acoustic comfort. Firstly, a barycentric power unit mounting system has been adopted to minimise the transfer of engine vibrations to the body by achieving reaction forces with zero offset.

This also helps improve the acoustic comfort of the new engine:
" An aluminium crankcase base with cast iron main bearing caps cast together;
" The development of an aluminium oil sump that is connected directly to the crankcase base and gearbox to increase the flexural and torsional rigidity of the entire power unit to reduce vibrations;
" The use of a damper with setting specially adjusted to damp vibrations with torsional resonance in the crankcase and flywheel system;
" Lastly, the adoption of an optimised piston skirt profile on which is deposited (screen-printed) a molybdenum bisulphate coating that allows piston/liner mating clearances to be pared to the minimum possible during production. This reduces noise produced by secondary movement of the piston in the cylinder (piston slap).

The 1.2 16v engine
The 59 kW 1.2 16v engine selected for the New Fiat Punto HLX features a modified torque delivery curve (114 Nm at 4000 rpm) for an even more satisfying drive with good performance and better fuel economy.

The engine also benefits from all the improvements described for the Fire 1.4 16v as far as the mechanicals, on-board electronics, exhaust system and fuel system are concerned.

This power unit also features a sophisticated piece of engineering not present on the 8 valve version. This takes the form of an electronic throttle driven by the engine control unit, a mechanism previously reserved for higher segment models. This device is wire-driven, i.e. operated without any mechanical connections between accelerator and throttle body. It leaves the electronic control unit the task of delivering torque in accordance with the driver's varying requirements. This is reflected in a top speed of 172 kmh, an acceleration figure of 0 to 100 km/h in 11.4 seconds and 33.2 seconds to cover a kilometre from a standing start.

The fuel consumption figures are also amongst the best in the segment: 6.0 l/100 km over a mixed cycle, 7.6 l/100 km for an urban cycle and 5.0 l/100 km over an extra-urban cycle.

A microhybrid electronic engine management system makes a crucial contribution to enhancing the vigorous temperament of the 1.2 16v engine. An aluminium crankcase base with linked main bearing caps has also been developed to improve engine performance as far as acoustics and noise levels are concerned.

Gearbox choice in the new Fiat Punto

There are three different gearboxes available in the new Punto, a five speed manual unit for the HLX, a six speed manual for the Sporting and a sophisticated CVT gearbox in the HLX.

Though they differ in terms of the maximum torque values they can handle (13.5 to 26 kgm), all the manual gearboxes share a dual cable external control that filters engine running unevenness and vibrations transmitted from the engine to the gear lever. The gear teeth offer high meshing capacity while the fifth speed and final drive gear sets are machined to a superfinish after heat treatment for lower noise levels. The gear casings are light and very effective at absorbing noise. The gear cases are developed using finite element structural computing methods.

The gear ratios are very long for good fuel economy while the clutch control is hydraulic to assure - yet again - low running noise, ease of use and efficiency.

The 13.5 kgm gearbox that is fitted to 1.2 and 1.4 16v power units. The sixth speed in the Sporting is non-overdrive on this version: the car reaches its top speed when in this gear. Both gearboxes take up little space and their selection levers offer outstanding manoeuvrability. This has been achieved by reducing clutch driven plate inertia and introducing new gaskets. The gearbox configuration is transverse with two shafts in a cascade, while the gear mechanism is internal over four selection planes.

Speedgear
Apart from the New Fiat Punto you can count on the fingers of one hand the cars in this segment with an electronically-controlled continuous automatic transmission - and in 1999, the previous model that originally launched the unit was the only one in the world.

In this type of device, a pulley and steel belt system offers a continuously variable transmission ratio to ensure a gear range (ratio between longest ratio and shortest ratio) that is much broader than on conventional automatics.

The New Fiat Punto device also allows a choice automatic mode and manual management with sequential shifts.

Two gearboxes in one - and more. When the unit changes over to automatic, the driver can choose between two operating modes: one designed for performance and the other for comfort. All in all, the driver can always choose between three driving modes: two automatic and one manual (sequential). When in manual mode, gear changes can be made without taking your foot off the pedal and six speeds are available.

The new Speedgear gearbox is complemented by a torque converter in place of an electromagnetic clutch and this brings considerable benefits. It reduces fuel consumption and increases the engine brake effect because converter locking is governed by gearbox software. Take-off is smoother, steep gradients can be climbed without problems and parking manoeuvres are easier.

The electronically controlled device ensures smooth operation and jerk-free management of transitions in acceleration and over-run because the accelerator operating signal may be filtered.

From an engineering viewpoint, an automatic transmission is the best complement to a power unit: partly because it can exploit engine power to the full while safeguarding it from stress and partly due to the driving comfort it offers. For example, the system includes an electronic device for detecting a fast acceleration request (corresponding to a downshift on a manual gearbox) that is more sensitive and effective than the kick-down on a conventional automatic transmission. When in manual mode, the Speedgear allows the driver to decide which gear to engage for driving satisfaction and performance.

To choose this driving mode, simply move the lever to D position and then move sideways into the gate to the left of the automatic selection gate. In this position, the lever can only carry out two movements: forward to change up and back to change down. Each gearshift is shown on the display. When the vehicle stops, the device changes to first gear ready to set off.

When it changes to automatic mode (lever in position D), the system offers further selection opportunities. In other words, between a livelier gearbox management strategy (short ratios) and a more comfortable strategy that is better suited for town driving, for example. In the latter case, the gearbox automatically selects longer and thus quieter ratios.

Through its electronic link to the accelerator - drive by wire - this gearbox also ensures very smooth operation during acceleration and over-run for a highly satisfying drive.

To select one of the two driving modes, you have to press a button on the gear control panel. You can switch from one to another at any speed. The speed engaged (if a manual gearbox is used) or the selected operating mode (for an automatic transmission) is indicated on the instrument panel.

Device functions are designed to safeguard the unit itself and assure absolute control over the car at all times.
" SHIFT-LOCK: this device allows you to move the control lever from position P only after pressing the brake pedal;
" KEY-LOCK: the ignition key may be removed only with the gearbox in position P;
" START-UP: the engine may be started only with the gearbox in positions N or P;
" EXCESS RPM: the system engages a higher speed before the engine reaches an excessive rpm. Conversely, it delays the changeover to a lower gear when the manoeuvre seems likely to increase rpm to excessive levels (only in manual position);
" REVERSE: reverse cannot be engaged above a certain speed. When the speed again drops below a set limit, reverse may be engaged. With the control in R position, the system automatically activates the reversing lights.

Features and equipment in the new Punto
The Fiat Punto boasts features that until now have been the preserve of higher segment cars and is ahead of many of its competitors in this field. One example is an automatic dual zone climate control system that makes its first appearance in segment B on this very model. Another example is Dualdrive electric power steering: though the previous Punto was first to introduce this device in 1999.

Automatic dual zone climate control system

Interior climate is one of the main comfort factors during a trip and is also very important for interior safety because temperature, humidity and ventilation affect the driver's well-being and thus his level of alertness. And of course the heating and ventilation system is also responsible for demisting the windscreen and side windows.

For this reason, the New Fiat Punto comes with a sophisticated climate control system that automatically controls temperature, air flow, air distribution, compressor activation and recirculation by means of an electronic control unit. It also acts as a dual zone climate control system, i.e. able to ensure two different temperatures simultaneously: one in the right part of the passenger compartment and the other in the left.

The quality of air reaching the inside of the car is improved by a filter that traps particles measuring more than 0.5 microns and pollen (that could cause allergies).

The New Fiat Punto also implements an equivalent temperature climate control strategy. It records internal and external temperature by means of certain sensors and assesses the sensation of thermal well-being experienced by passengers, i.e. the energy exchange between human body and passenger compartment that is affected by humidity, temperature and treated air flow.

Another sensor located in a central position at the windscreen base records solar radiation on the car and the angle at which the rays strike the passenger compartment. This allows the system to prevent an excessive increase in temperature inside the car caused by the sun and thus to inform the climate control system in time.

All these parameters are monitored continuously and used to update the distribution, ventilation and mixing automatically. Air temperature and fan speed are therefore adjusted to ensure passengers experience the desired sensation of thermal well-being (achieved by setting the required temperature).

The result is a constant climate, even with significant changes in external conditions.

The system may be adjusted to one of five set combinations to allow air taken into the car to reach all areas of the passenger compartment:
" 'def', directs air only to the windscreen to demist and defrost;
" 'vent', offers an immediate sensation of well-being as the interior reaches the required temperature;
" 'floor', assures rapid heating;
" 'bi-level', directs warmer air from the floor outlets and cooler air from the facia outlets;
" 'heat', ensures the passenger compartment is properly heated and also prevents demisting.

The system also offers three possible temperature settings:
" 'LO' (maximum cooling) that is activated when a temperature setting of below 16.5°C is chosen. In this case, the system ensures that the air distribution is directed to the front (vent position); air flow is the maximum permitted by the device and the compressor is on (recirculation is set by the user);
" 'HI' (maximum heating) becomes operational when the temperature requirement is higher than 32.5°C. Air distribution is set to the floor position; output is again as high as possible; the compressor is controlled as required by the control unit and recirculation is left to the motorist's discretion;
" 'MAX DEF' (fast defrost), essential in winter, during periods of high rainfall and sometimes in spring and autumn; the compressor comes on automatically to ensure air taken into the passenger compartment is dehumidified and the windscreen and rear window are demisted/defrosted quickly.

The possibility of altering interior temperature gradually, half a degree at a time, makes for outstanding climatic comfort. The knob can be used to bring about a temperature change of 16°C, with a maximum temperature difference of 7 degrees between the left and right areas.

Manual adjustment is used for:
" setting interior temperature (right and left),
" voluntary changes to air flow distribution,
" fan speed (to alter air flow) and fan shut-off,
" compressor deactivation (in practice, the system works as an automatic heater),
" the recirculation control,
" the 'MAX DEF' function for fast demist/defrost.

Manual choices always over-ride automatic settings. They are also indicated by deactivation of the Full message (Auto remains visible) and stored until the user cancels the command. Each time the system is turned on, it returns to the conditions saved upon deactivation, except for the 'MAX DEF' function, which is zeroed. The entire system can also be turned off manually to deactivate the air conditioning system fully.

Dualdrive electric power steering
The power steering system is a particularly attractive new addition introduced on the previous model and also available for the New Fiat Punto. It comes with two operating modes and uses the power generated by an electric motor instead of power from a hydraulic pump driven directly by the engine.

This device is just as revolutionary as the alternator, electronic ignition and front wheel drive in their day and is destined to bring about a considerable increase in energy saving, noiselessness, reliability and respect for the environment while also significantly improving the way we drive and enjoy our cars. As far as customers are concerned, Dualdrive electric power steering represents the end of an age of compromises.

This is because, to date, designers have always been forced to choose an average effort to be applied to the wheel halfway between maximum steering lightness (best for parking) and a much stiffer control effective at high speed (ensures better control).

This occurred because the power steering servo level is constant at any speed.

The steering response of the Fiat Punto's electric steering system is, however, proportional to car speed: the higher the speed, the lower the assistance and the stiffer the wheel response to ensure greater driving precision.

The Fiat Punto system is particularly innovative even for an electric power steering system and offers customers an extra feature: i.e. a choice of two different setting programs. The first ensures maximum empathy between driver and car and is ideal for mixed out-of-town routes. The second lightens the steering to minimise effort and is therefore ideal for driving round town and parking manoeuvres.
To turn on the latter, all you have to do is push the city key in the middle of the facia. But fear not if you set off down the motorway with the device in this position. To ensure customers maximum safety in all cases, both programs offer the same degree of power assistance over 70 kmh and therefore ensure a steering wheel response suited to high speed.

The Fiat Punto's electric power steering system is easy to use, satisfying and safe and also offers other advantages: after cornering - for example - steering wheel return is controlled actively with speed and damping adjusted to driving conditions.

These benefits can be perceived by anyone entering a Fiat Punto for the first time while others become evident at a later stage. Fuel saving is the first and foremost of these additional benefits.

Unlike a conventional power steering system that requires the pump to be driven continually, the Dualdrive electric power steering only takes up power when necessary, i.e. when the steering wheel is turned.

This result is a lower power requirement and a consequent fuel saving of 3% over mixed routes. Equivalent to the effect of reducing car weight by 50 kg.

Lower fuel consumption, therefore, and also a more noiseless passenger compartment due to elimination of the noisy hydraulic pump.

On the environmental front, electric power steering helps reduce emissions (as a direct consequence of the lower fuel consumption) but also increases percentage recyclability of the device itself. Because the unit contains no fluid or rubber to be disposed off, the figure of 85% for hydraulic systems is increased to 95% for the electrical system.

The component is also highly reliable because it works at a lower temperature than a hydraulic power steering system and is not affected by possible impurities in circuit fluid.

The device, simple in concept but difficult to build, is built into the steering column and includes an electronic control unit, an electric motor, a toothed coupling and a steering wheel position and torque sensor.

The Dualdrive electric steering system is also absolutely safe. If a fault occurs, a warning light comes on and the Fiat Punto may be steered in the same way as any car with manual steering. For safety reasons, the system will work only with the engine running.

ABS
The ABS fitted to the New Fiat Punto Sporting is the latest Bosch 8.0 and offers four active sensors, four channels, an electronic control unit and eight solenoids. It is complemented by an EBD (Electronic Brakeforce Distribution).

This system ensures that any wheel at the point of locking can brake as effectively as possible. In emergency situations, it also allows full directional control of the car by means of the steering wheel.

The strength of the system lies in the active sensors that process the wheel speeds (without the intervention of the control unit).

They can also read values close to zero (passive sensors cannot record speeds lower than 2.5 kmh) and are less sensitive to interference caused by electromagnetic fields.

This advanced ABS is complemented by an electronic brakeforce distributor EBD. This divides braking action over all four wheels to prevent the rear wheels from locking and ensures a balanced car response under all conditions. The system also adapts system operation to wheel grip conditions and pad efficiency. It also reduces front brake temperatures and the brake servo thrust requirement.

ESP
To ensure greater mastery of the car, the New Fiat Punto also offers the sophisticated Electronic Stability Program, a system that cuts in under near-limit conditions when car stability is at risk and helps the driver to control the car.

To achieve this result, the ESP continually monitors tyre grip in both longitudinal and lateral directions. If the car skids, it cuts in to restore directionality and ride stability. It uses sensors to detect rotation of the car about its vertical axis (yaw speed), car lateral acceleration and the steering wheel angle set by the driver (which indicates the chosen direction). It then goes on to compare these data with parameters generated by a computer and establishes - via a complex mathematical model - whether the car is cornering within its grip limits or if the front or rear is about to skid (understeer or oversteer).

To restore the correct trajectory, it then generates a yawing movement in the opposite direction to the movement that gave rise to the instability by braking the appropriate wheel (interior or exterior) individually and reducing engine power (via the throttle).

This is the key attribute of the device created for the New Fiat Punto. It acts in a modulated fashion on the brakes to ensure the action is as smooth as possible (and the drive is not therefore disturbed). The engine power reduction is contained to ensure outstanding performance and great driving satisfaction at all times. The ESP is permanently engaged.

ASR and MSR
The New Fiat Punto Sporting is fitted with a very sophisticated automatic traction control device to restrict drive wheel slip in the case of reduced road grip. This is known as ASR (Anti Slip Regulation) and comes as standard on all versions equipped with ESP. The ASR works at any speed and acts on the torque according to the measured grip coefficient.

The device computes degree of slip on the basis of wheel rpm calculated by the ABS sensors and activates two different control systems to restore grip:
" when an excessive power demand causes both drive wheels to slip (e.g. as occurs during aquaplaning or when accelerating over a road surface that is uneven, snow-covered or icy), it reduces engine torque by reducing the throttle opening angle and thus air flow;
" if only one wheel slips (e.g. the inside wheel following acceleration or dynamic load changes), this is automatically braked without the driver touching the brake pedal. The resulting effect is similar to that of a self-locking differential.

The ASR maintains vehicle safety as much as possible and is particularly useful when grip is lost (icy multi-storey car park ramps are one example) and whenever the asphalt does not guarantee even friction.

Another not inconsiderable advantage of the ASR is the lower stress exerted on mechanical parts such as the differential and gearbox due to more effective control of low speed take-off and traction.

The ASR comes on automatically whenever the engine is started. To turn off the device, all you have to do is press a switch on the central console. When the ASR is active, a warning light on the control panel flashes.

A control panel warning light comes on (with the switch led off), to indicate system faults or irregularities. ASR deactivation is required when snow chains are used because the wheel must be able to slip by tiny amounts to pile up the snow so that force can be transmitted to the ground and the ASR tends to avoid this type of action.

The MSR (Motor Speed Regulator) cuts in when the gear is shifted down abruptly under conditions of low grip. This device restores torque to the engine to prevent the wheel skidding as a result of lock.

Emergency Brake Assist (EBA)
The New Punto Sporting offers a device to assist with emergency braking. On vehicles with ESP, the function is carried out electronically by the ABS control unit and is referred to as Emergency brake Assist (EBA).

In emergency braking situations, most drivers recognise a situation of danger and press the brake pedal very quickly. But not with sufficient force. This is because people, unless they are professional drivers, are used to applying a certain load to the brake pedal. As people tend to switch to autopilot mode when they carry out repetitive actions, the same level of force tends to be applied in all circumstances.

On the new model, however, the brake assist devices cut in at this point. Although the pressure on the pedal is unchanged, the car is decelerated by the same amount, as it would be if it were braked with all the necessary force.

And there is more. Emergency brake assist devices can even help experienced drivers who brake quickly and apply the correct amount of force in emergencies. This is because the system reduces brake activation time in all cases, i.e. the period between the time when pressure begins to be applied to the pedal and the moment when the circuit reaches maximum pressure and is able to offer maximum performance.

Hill Holder
The Hill Holder helps drivers on hill starts. It operates when the ESP control unit perceives a change in vehicle gradient by means of a longitudinal acceleration sensor located on the floor under the passenger seat. During hill starts, the control unit is ready to intervene when first gear is engaged and both brake and clutch pedals are pressed. Front calliper pressure is thus maintained for about 1.5 seconds after the brake pedal is released so that the driver can set off with ease. The Hill Holder function does not operate when setting off downhill with the first speed engaged. The system performs in the same way with reverse engaged: during downhill starts, the system is active but deactivated during hill starts.
