The 1.3-litre MultiJet engine, now in its second generation, has featured in some of Fiat’s most popular cars including the Panda city car, the retro-styled Fiat 500 and the larger Punto Evo hatchback and Qubo MPV.
The four millionth model was produced at the Bielsko Biala plant in Poland seven years after the technology was first introduced into Fiat’s cars.
The 16V engine was updated in 2010 and added to the popular Fiat 500 range. Featuring fuel-saving technology such as Start&Stop, the MultiJet II engines delivers 95bhp and CO2 emissions of 104g/km.
This is enough to qualify for zero first year road tax while still propelling the compact car to 62mph from standing in 10.7 seconds and to a top speed of 112mph.
On its introduction to the Fiat 500 in early 2010, the engine held the honour of being the most powerful diesel engine in the city car segment despite the low CO2 emissions and impressive fuel economy of 72.4mpg.
Fiat’s common rail diesel technology is widely recognised as the leader in diesel technology, an accolade the manufacturer is also chasing with its petrol engines.
The MultiAir and all-new TwinAir petrol engines reduce CO2 emissions and improve fuel economy in Fiat’s small car fleet.
The TwinAir in particular is winning headlines for its two-cylinder layout and sub-100g/km CO2 emissions in the Fiat 500 – the only petrol engine on the market to do so.
All MultiJet and MultiAir engines in the Fiat range qualify for Euro 5 criteria – the EU emissions and engines regulations all new cars must abide by from the start of 2011.
