The new 165 HP Multiair 1.4 turbo petrol engine is the result of a winning partnership between Fiat Powertrain Technology and Abarth race-derived know-how.
Since the Fiat Powertrain engine was first presented at last year’s Geneva motor show, Abarth engineers have been working hard to squeeze every last drop of power out of it and to improve its sporting performance in typical Abarth style.
Multiair engine technology has revolutionised the world of petrol engines. Compared to a conventional petrol engine of equivalent size, a MultiAir engine develops more power (up to 10%) and more torque (up to 15%), while consuming significantly less (up to 10%) and emitting less CO2 (up to 10%), fewer particulates (up to 40%) and less NOx (up to 60%).
The genius of the Multiair engine is embodied in its electro-hydraulic valve control system. Both fuel consumption and pollutant emissions have been slashed by using the engine’s intake valves to control the air flow directly, without a butterfly valve in the intake. Using this already advanced technology as a starting point, Abarth’s development department has made a series of modifications to arrive at the innovative new 165 HP Multiair 1.4 16 V. Power output, for example, has been optimised by the intelligent application of a new, larger turbocharger from Garrett. The result is superb performance with peak torque of 250 Nm (25.5 kgm) at 2250 rpm, and acceleration from 0 to 100 km/h in only 7.9 seconds.
