A memorable event was organised, once again in Turin, on 4 July 2007 to introduce the new Fiat 500, exactly 50 years after the debut of the Fiat 500. From that day, the second generation of the model that epitomised the history of Italian cars, was quick to win everyone's hearts. For the many enthusiasts and customers worldwide, Fiat decided to celebrate each birthday of the pocket-sized 500 with special events and by introducing a new product bound to appeal to all. In 2008, for example, picnics were organised in the main European capitals and the mighty 500 Abarth was introduced. The same thing happened in 2009 for the international presentation of the Fiat 500C, the original cabriolet version intended as a homage to the style of the 1957 open-topped car, which has already notched up more than 34,000 orders. Last July, to celebrate the car's third year in existence, Fiat chose to launch its 85 HP (875 cc) TwinAir twin-cylinder engine on the 500 model, both saloon and cabriolet.
The 500 is the first Fiat model to adopt this forerunner of a new family of engines: a 85 HP turbo two-cylinder with the lowest CO2 emission levels in the world for a petrol engine (92 g/km with a Dualogic robotised gearbox and 95 g/km with manual gearbox). All this is achieved without detracting from performance and driving satisfaction. This is thanks to the small-sized turbine which, combined with dedicated valve management strategies, minimises transient response times and, at the same time, keeps maximum power levels high. In this way, despite its small size, the engine ensures excellent performance and an appreciable reduction in fuel consumption: compared with a 1.2 8v, the 85 HP TwinAir records a power increase of 25% despite a 15% reduction in fuel consumption. In fact, the performance of the twin-cylinder unit is not only equivalent to a 1.4 16v, but its fuel consumption is a remarkable 30% less.
A Fiat 500 powered by a TwinAir engine can reach a top speed of 173 km/h and accelerate from 0 to 100 km/h in only 11 seconds. This remarkable performance corresponds to a significant reduction in fuel consumption: in the combined cycle 4.0 l/100 km and 4.1 l/100 km with a Dualogic robotised gearbox and manual gearbox respectively. The Fiat 500 with an 85 HP TwinAir also comes with an ECO button positioned on the dashboard to cut fuel consumption still further around town and guarantee a genuinely eco-friendly drive by offering driving modes: Normal and ECO.
In the first mode, the ECO function is off and the engine delivers the maximum available torque (145 Nm), guaranteeing verve and a prompt response for a sportier drive. Steering power-assistance is also specifically calibrated for Normal mode. No indication appears on the dashboard in this mode (City is not selected). This configuration is therefore recommended for maximum response and full appreciation of all the available torque.
In ECO mode, on the other hand, the emphasis is on an eco-friendly drive: torque delivery is limited to 100 Nm at 2000 rpm to minimise fuel consumption and promote a driving style more suitable for town traffic. The effort required at the steering wheel is also lighter (CITY mode is automatically selected). The driver only needs to press the specific button on the dashboard to activate the ECO function. The lettering ECO will appear on the control panel (the letter E will appear on the panel if the car has a Dualogic robotised gearbox). The Dualogic shifting strategy also switches to ECO mode to further optimise fuel consumption when a Dualogic gearbox is fitted.
Compared to a medium-sized four-cylinder unit of equal performance, the new engine is also significantly shorter (-23%) and lighter (-10%), opening the way to further developments, such as methane fuel system or hybrid technology combinations, again with a view to greater eco-friendliness. In particular, a methane version of the TwinAir will soon be available, guaranteeing a further CO2 emission reduction by adopting a pair of special injectors in addition to the petrol injectors on the intake manifold duct branches. Improving on these fuel saving results using internal combustion engines will be difficult and alternative technologies will need to be developed. The combination of traditional engines and electric motors appears particularly promising. Due to its reduced size, the TwinAir is very suitable for pairing with an electric engine and in general with any device located between the engine and gearbox designed to recover and store the energy that is normally dissipated during braking.
The 85 HP TwinAir unit also comes with Start&Stop as standard. This device temporarily stops the engine and restarts it, ensuring reductions in fuel consumption and noise in the passenger compartment when the device is in operation. The Gear Shift Indicator (GSI) fitted in conjunction with the Start&Stop is a veritable co-pilot that discreetly suggests to drivers when they should change gear, leading to more efficient use of the power unit in terms of fuel consumption. For example, the GSI may suggest shifting up, by means of an indication on the control panel, to allow the engine to burn a leaner mixture, i.e. one containing less fuel, or shifting down to make best use of the available torque.
Nothing short of an engineering gem, the two-cylinder implements the revolutionary MultiAir technology developed and patented by FPT Fiat Powertrain Technologies, which was introduced last year for the first time. The heart of MultiAir is a new electro-hydraulic valve management system that reduces fuel consumption by controlling air directly via the intake valves (without using the throttle). MultiAir reduces polluting emissions (thanks to improved combustion control) and also considerably improves performance by boosting driveability with respect to a traditional petrol engine of equal displacement. In brief, the advantages of MultiAir technology applied to petrol engines are:
- maximum power boosted by 10% with respect to a traditional engine of equal size;
- 15% more torque at low rpm and during transitions by applying early intake valve closing strategies to maximise the air introduced into the cylinders;
- less fuel consumption and consequently lower CO2 emissions, equal to 10% by eliminating pumping losses and precise parameter calibration for optimising combustion;
- lower polluting emissions from the engine by optimising valve control strategies during the intake stage;
- prompter response to accelerator commands due to the constant air pressure upstream of the cylinders combined with extremely fast control of the intake valves.
The new TwinAir engine also takes the concept of downsizing to an extreme: by combining a small-sized engine with a next-generation turbocharger performance comparable to or even better than that of a larger engine is obtained but with less fuel consumption and lower emissions. Not only that, the turbo significantly increases the maximum torque, making it available at a very low rpm, with the result of offering greater flexibility and an unrivalled responsiveness compared to conventional aspirated engines. All this comes with a simple build to the benefit of strength and reliability.
Last but not least, the new engine was painstakingly optimised and tuned. For instance, the basic twin-cylinder architecture - combined with the low friction of internal parts - makes this engine best-in-class at a world level in terms of friction losses.
Furthermore, calculated simulations have been used to identify the best possible unit displacement in terms of thermo-dynamic efficiency, and the best fluid dynamic configuration to optimise and get the best out of the MultiAir system. Finally, special attention has been placed on the NVH (Noise, vibration, and harshness) aspect to ensure vibration performance at least equivalent to that of a four-cylinder, with equal performance but with a characteristic sound. For this purpose, a balancing countershaft was used to maintain optimal vibration levels in all operating conditions of the engine, from idling speed to maximum power.
Significantly, the new 85 HP TwinAir twin-cylinder engine will complement the many technological solutions already adopted on the Fiat 500 to limit consumption and emissions, as demonstrated by the recent expansion of the engine range, now featuring a second-generation 1.3 MultiJet delivering up to 95 HP. With 8 injections per cycle, the 1.3 MultiJet II improves low rpm torque delivery by up to 38% and cuts CO2 emissions by 6%. Again with a focus on environmental protection, the Fiat 500 (saloon and cabrio) is available with Start&Stop, the system which temporarily stops the engine and starts it again when the car is stationary with the engine idling: this reduces urban cycle average consumption by up to 12%. The Fiat 500 range also offers eco:Drive, innovative software for analysing driving behaviour and helping motorists optimise consumption and emissions by using the USB port of the Blue&Me system.
Finally, Blue&Me TomTom, the latest evolution of the Blue&Me system, will be appearing on the Fiat 500 along with the new TwinAir engine. This is a fully integrated infotainment system that allows you to manage telephone, navigation and useful driving information functions through the Tom Tom's colour touch screen interface. The application of this system on the Fiat 500 will also enable additional functionality that will also allow the mediaplayer to be managed through the touch screen interface. The Blue&Me n TomTom is located in a dedicated housing on the dashboard that combines the safety, convenience and practicality of an integrated solution with the flexibility of portable devices. The device is constantly charged through the dedicated housing and may be controlled by means of steering wheel controls and also the touchscreen interface.
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 car's other systems via the Blue&Me system developed in collaboration with Magneti Marelli.
