Technological innovation


The technological excellence of the Fiat Punto Evo is in evidence primarily through the extensive range of engines, designed and manufactured by FPT – Fiat Powertrain Technologies, that can be powered by petrol, petrol/LPG, petrol/methane or diesel. The engines are available at Euro 4 and Euro 5 ecology standards (except for the 1.2 petrol engine, which will be available in Euro 5 from 2010). They include the new 1.4 MultiAir and second-generation 1.3 MultiJet: all meet Euro 5 standards and come with the Start&Stop system as standard.
The Punto Evo represents another advancement in sustainable transport, and it is a step ahead of the EEC regulation that requires new cars to comply with Euro 5 limits only from 1 January 2011.
Depending on the engine, you can get five or six-speed mechanical or robotised sequential gearboxes (Dualogic) that have been optimised for excellent manoeuvrability and very low noise levels.
The following engines are available at launch:

Petrol:
65 hp 1.2 8v (Euro 4);
77 hp 1.4 8v (Euro 4);
77 hp 1.4 8v (Euro 5) with Start&Stop;
105 hp 1.4 MultiAir 16v (Euro 5) with Start&Stop;
135 hp 1.4 MultiAir Turbo 16v (Euro 5) with Start&Stop.

The logo on the rear door of the Punto Evo changes according to the different engine types: the dot is red for high-performance engines (135 hp 1.4 MultiAir Turbo and 120 hp 1.6 MultiJet), green for bi-fuel units and black for other engine types.


MultiAir technology

Making its debut on the Fiat Punto Evo, the 1.4 MultiAir is the revolutionary head of a new family of engines equipped with the MultiAir technology developed and patented by FPT – Fiat Powertrain Technologies. The technology will be gradually rolled out across all Fiat Group engines.
Available in two different power outputs (105 hp and 135 hp), the new engine represents a real departure point from the current petrol engine scene. Compared with a traditional petrol engine with the same cubic capacity, the MultiAir engines provide a significant increase in power and torque, as well as much lower fuel consumption and emissions.
At the heart of the MultiAir is a new electrohydraulic valve management system that enables reduced fuel consumption (by controlling air directly via the engine intake valves, without using the throttle) and harmful emissions (via combustion control), as well as improved performance. As befits a flag-bearer for the downsizing concept, MultiAir is a versatile technology that is easily applied to all petrol engines and may potentially be developed for diesel engines.
The 135 hp 1.4 MultiAir Turbo guarantees the Fiat Punto Evo all the performance and temperament of a sporty, well-balanced car designed for customers who want good driveability and fuel economy. Thanks to the turbocharger, the torque delivery of the 135 hp engine is optimum under all conditions and ensures outstanding acceleration and vigorous thrust at all revs, setting a new benchmark for petrol engines. The new 135 hp engine's top speed and time to accelerate from 0-100 km/h puts it at the top of the supermini class: 200 km/h (205 for the Sport version) and just 8.5 seconds. Excellent performance is combined with respect for the environment (Euro 5 approval) and good fuel economy. This excellence is reflected in particularly low CO2 emissions, equal to 129 g/km, with a combined fuel consumption of just 5.6 litres every 100 km.
Balance and temperament are also attributes of the 105 hp 1.4 MultiAir power unit. This engine sits in the middle of its reference market, where it represents the best choice. The 105 hp MultiAir also complies with Euro 5 standards and records 134 g/km of CO2 (combined fuel consumption is just 5.7 litres every 100 km). Performance is excellent: from 0-100 km/h in 10.8 seconds and top speed of 185 km/h.
All this tells you that MultiAir has all the necessary attributes to be as revolutionary in the field of petrol engines as JTD and MultiJet were in their day for diesel engines. Fiat's long tradition in engines continues.


Second-generation MultiJet

All Fiat Punto Evo diesel engines are equipped with the next-generation MultiJet Common Rail injection system. This highly advanced solution can control high engine pressures (up to 1600 bar) without being tied to engine speed or the quantity of fuel injected.
In the 1.3 MultiJet Euro 5 versions, the system uses innovative common rail injectors that, thanks to a balanced hydraulic servo-valve, are able to more precisely control the quantity of diesel injected into the combustion chamber, with a faster and more flexible sequence of injections than was previously possible. By reducing the amount of time between injections, these injectors optimise fuel introduction to the chamber and therefore make the diesel combustion process more gradual, with positive effects for consumption, emissions, NVH and handling. In fact, the new common rail injector on the Euro 5 engines cuts consumption and CO2 on the approved cycle by around 2%, while at the same time reducing harmful emissions.
The second-generation MultiJets are therefore the latest development in the Common Rail injection system which, after the JTD (1997) and MultiJet (2003) engines, gives the Fiat Group yet another first in this field.  
The 1.3 MultiJet is available in Euro 4 (75 and 90 hp) and Euro 5 (75 and 95 hp) versions, the latter coming with a particulate filter and Start&Stop as standard. In addition, turbo is carried out either by a fixed geometry turbocharger (75 hp) or a variable geometry turbocharger (90 and 95 hp). The Euro 5 versions have next-generation turbochargers that, combined with the new second-generation MultiJet injection system, ensure the best possible turbo function at any engine operating level, with torque delivery at low revs up to 25 per cent higher than on Euro 4 versions.
The performance levels of the 95 hp second-generation 1.3 MultiJet (Euro 5) are well worth a mention: top speed of 178 km/h, 0-100 km/h in 11.7 seconds, consumption of 4.2 l/100 km and 110 g/km of CO2 emissions (in the combined cycle). When combined with the Dualogic gearbox, consumption falls to 4.1 l/100 km and emissions to 107 g/km.
Finally, the Punto Evo range retains the brilliant 120 hp 1.6 MultiJet Euro 5 with DPF from the previous model. With this engine, the car can reach a top speed of 193 km/h (Sport version) and go from 0-100 km/h in 9.6 seconds. Excellent performance also comes with reduced consumption and emissions: in the combined cycle, these figures are 4.5 l/100 km and 119 g/km of CO2 respectively.


Start&Stop system and Gear Shift Indicator

With respect for the environment and fuel economy still in mind, the new Fiat Punto Evo includes the Start&Stop system. Coming as standard on all the new Euro 5 petrol and diesel engines, and from 2010 also on the 120 hp 1.6 and the 1.2 Euro 5, this device temporarily switches off the engine and restarts it in order to reduce fuel consumption and noise levels. In these situations, which are typical of heavy traffic in urban areas and when stopped at traffic lights, when the control strategy permits, the system automatically cuts out the engine in order to reduce fuel consumption and emissions by up to 15% for an urban route and 3.5% over an NEDC-type cycle.
Moreover, the Gear Shift Indicator (GSI) linked to the Start&Stop system is a kind of co-pilot that discreetly advises drivers when they should change gear, leading to a more fuel-efficient use of the engine. For example, the GSI may suggest shifting to a higher gear, by means of a signal on the instrument panel, in order to allow the engine to combust a leaner mixture, i.e. containing less fuel, or changing down a gear to make best use of the available torque.


Blue&Me–TomTom

Technological innovation also comes in the shape of the latest Blue&Me platform, which makes its debut on the Punto Evo. Blue&Me–TomTom is a fully integrated infotainment system whose practical colour touch-screen allows you to manage phone calls, satellite navigation and all the driving information you need. The device is the result of a partnership between Fiat Group Automobiles and TomTom, the European leader in portable navigation systems, and integrates with the other car’s systems thanks to the Blue&Me system developed with Magneti Marelli.
Blue&Me–TomTom is fixed in an easily accessible and safe position (without loose cables), from which it can nevertheless be removed for other purposes. The system can also be operated from controls on the steering wheel and by voice recognition. There is an exclusive “Car Menu” to let you display information on the car and all connected devices:
- “eco:Drive Info”: real-time information on your driving style and suggestions for reducing environmental impact and optimising consumption by changing gear and accelerating appropriately to suit the nature of the route;
- all trip information on a single screen: distance travelled, consumption and range;
- fuel reserve warning and directions to the nearest filling station;
- places of interest, Fiat Group service centres and methane and LPG filling stations;
- management of the mobile phone connected to Blue&Me: calls, information, contacts and call log.

Lastly, on this new Fiat model you can also get Blue&Me (including hands-free function with Bluetooth® interface and advanced voice recognition, USB port, MP3 player and SMS message reader) and Blue&Me Nav, which adds a satellite navigation function at a very competitive price. The innovative Blue&Me system has won prestigious international awards and been a real commercial success. It is fast approaching one million units installed on various Fiat Group Automobiles models.
