Straight success.

The straight six-cylinder petrol engines in the BMW Z4 sDrive23i, sDrive30i and sDrive35i.

Why does a roadster have an elongated bonnet? To accommodate six cylinders in a row. This is because only straight six-cylinder engines provide the perfect combination of weight and power coupled with dynamic balance and sophisticated smoothness. Constructed from a combination of magnesium and aluminium, the BMW Z4 sDrive23i (150 kW/204 hp) and sDrive30i (190 kW/258 hp) set new standards in dynamic engineering. And in the BMW Z4 sDrive35i, High Precision Injection and Twin Turbo help release up to 225 kW (306 hp) on command.
