The MultiJet II diesel engine making its debut in the Fiat 500 and 500C.

The new 1.3 Multijet II (Euro5) engine, with Start&Stop fitted as standard, is making its first appearance on the Fiat 500 and 500C models. It has a maximum power output of 95 HP at 4000 rpm and delivers a torque of 200 Nm (20.4 kg / 148 lbs ft)at only 1500 rpm.

Available on all trim levels, with an on-the-road list price that starts at 13,900 Euros, the new power unit delivers excellent performance (a top speed of 180 km/h and acceleration from 0 to 100 km/h in 10.7 seconds) with decidedly low consumption and CO2 emissions: 3.9 l/100km and 104 g/km (mixed cycle), respectively.

Developed and produced by FPT - Fiat Powertrain Technologies, the 1.3 Multijet II 95 HP engine belongs to the second generation of Multijet power units and has new common rail injectors which, courtesy of a balanced hydraulic servo valve, control the amount of diesel injected into the combustion chamber with a high degree of precision, making the injection sequence much faster and more flexible than previously (up to 8 injections in the same cycle). This allows better control of the diesel combustion with benefits for consumption, emissions, noise levels and drivability.

The new 95 HP engine on the Fiat 500 and 500C is equipped with a variable geometry turbocharger (!) that ensures optimum turbocharging throughout the entire operating range. Fuel consumption has been reduced by up to 8% in the urban cycle thanks also to the Start&Stop system that switches the engine off temporarily and then restarts it. With Euro 5 type-approval, the new 1.3 litre engine enhances its environmentally-friendly pedigree further through the particulate filter (DPF) integrated in the engine compartment which improves its efficiency even more, especially in the first few moments after cold starting.

The second generation Multijet power units represent the development of the common rail injection system which today, after the JTD (1997) and Multijet (2003) engines, allow Fiat Group Automobiles to steal a march in this field and be prepared for future regulations. The Multijet II engines use increasingly advanced "strategies" to improve combustion: for example, the use of injection rate shaping (two consecutive injections with no hydraulic interval) reduces noise, fuel consumption and, in view of Euro 6, harmful emissions (a potential 30% reduction of nitrogen oxides).

Lastly, together with the new 1.3 Multijet II 95 HP engine, the new rear torsion beam (semi-independent) suspension with an anti-roll bar is also making its debut on the Fiat 500 range. It is derived from the Abarth 500 model and has already made an appearance on the 500C. It gives better handling and a more comfortable ride.
