Our inline six engine offers smooth power, greater acceleration and 200 lb-ft of torque at 2750 rpms. A number of pioneering technologies make it possible. An electronically controlled water pump helps increase power output. Our patented Valvetronic system offers better fuel efficiency. And to save weight, we used a groundbreaking innovation that BMW was the first to use in a production car - an engine block made of a lightweight composite magnesium/aluminum.
