A hybrid that breaks all the rules.
The all-new BMW ActiveHybrid 5 is an efficient force to be reckoned with. It's the first hybrid to use a BMW in-line 6-cylinder engine and it uses the same TwinPower Turbo technology as the 535i Sedan. Even the electric motor provides a performance boost to the gas engine for more acceleration. So not only is it just as powerful as a 535i Sedan with a conventional gasoline engine, it gets even better gas mileage.
