The straight six-cylinder petrol engine in the BMW 535i.
How do you improve an engine that has already won the Engine of the Year Award several times? With an eye for detail and a new concept including a Twin Scroll turbocharger, Valvetronic and direct injection. Each one of these technologies has been further developed and combined for the first time in a BMW in one package: with an output of 225 kW/306 hp and 400 Nm, the straight six-cylinder engine offers outstanding performance combined with truly impressive all-round economy with fuel consumption at just 8.9 l/100 km.
