The new two-cylinder engine family made by FPT - Fiat Powertrain Technologies, called TwinAir, is debuting in the Fiat 500 today. This is a brand-new concept on the worldwide auto scene and confirms the leadership of the Fiat Group in this field. Using next-generation technology, the new engine implements the revolutionary MultiAir system combined with special fluid dynamics optimised for maximum fuel efficiency. Furthermore, by taking the concept of downsizing to the extreme and masterfully tuning the basic mechanics, the new family -- delivering from 65 to 105 HP -- emits 30% less CO2 than an engine of equal performance.

On sale from next September, the 500 will be the first Fiat model to adopt this, which will be the progenitor of a new family of engines: a 85 HP (900 cc) turbo two-cylinder with the lowest CO2 emission for a petrol engine (92 g/km with a Dualogic robotised gearbox and 95 g/km with manual gearbox) without skimping on performance or driving pleasure. 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 new 85 HP turbo has 23% more power and a 30% better performance index. In fact, the performance of the two-cylinder is not only equivalent to a 1.4 16v, but consumption is a remarkable 30% lower.

Equipped in this way, the Fiat 500 reaches a top speed of 173 km/h and accelerates from 0 to 100 km/h in only 11 seconds. This remarkable performance corresponds to a significant reduction of fuel consumption and emissions: 4.1 l/100 km and 95 g/km respectively on the urban cycle (with manual gearbox), that becomes 4.0 l/100 km and 92 g/km with a Dualogic robotised gearbox. Furthermore, the Fiat 500 with TwinAir 85 HP is provided with an ECO button -- positioned on the dashboard -- for further cutting fuel consumption in cities and guaranteeing very eco-friendly running. Two driving modes can be selected: Normal and ECO.

In the first mode, the ECO function is off and the engine delivers the maximum available torque (145 Nm), guaranteeing prompt, brilliant response and a "sportier" driving feel. Steering assistance is also specifically calibrated for Normal mode. No indication appears on the dashboard in this mode (City is not selected). Consequently, this configuration is recommended for maximum response and full enjoyment of all available torque.

In ECO mode, instead, the emphasis is on "eco-friendly" engine running: torque delivery is cut off to 100 Nm at 1750 rpm to minimise consumption and promote a driving style more suitable for city traffic. The steering wheel is 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 panel (the letter "E" will appear on the panel if the car has a Dualogic robotised gearbox). Furthermore, the Dualogic shifting strategy also switches to ECO mode to further optimise fuel consumption.
