News about the debate on BMW ‘s possible new small petrol turbo engines had been going on for some times. From anonymous source, the new engine will comprise of a a 1.35-litre three cylinder and a larger 1.8-litre four cylinder.
In total, there is actually five engine tob built, three 1.35-litre and two 1.8-litre engine. All those engine will be installed in the 1 and 3 Series cars and maybe in the baseline 5 series, X3 and X1 as well.Power is said to range from 163bhp (122kW) and 140 lb-ft (190Nm) for a baseline model, to 241bhp (180kW) and 192 lb-ft (260Nm) for the 1.35-litre. The 1.8-litre will produce a massive 273bhp (204kW) minimum and 321bhp (239kW) tops.
Previously, BMW already has a small 2 liter twin turbo diesel which were used in the 123D for 150kW (201bhp) and 400Nm.Bu the engine seems inferior compared to the compact four-pot petrol turbo engines build by Audi and Mercedes Benz. But with this new engine, BMW may catchup with their competitor.
Apparently these BMW engines will be ready for production by the year 2011. They will be cleaner, more powerful and more efficient than current normally aspirated engines. The bigger twin turbo petrols like the 3.0-litre and 4.4-litre V8 will stay in the lineup.
