Under the Hood

Both engines incorporate direct fuel injection and turbocharging. The xDrive35i uses a new 3.0-liter inline-six-cylinder with one turbocharger, while the xDrive50i uses a 4.4-liter V-8 with two. Power ratings are unchanged on the new six-cylinder, but BMW says it is more efficient. BMW says both engines promise minimal turbo lag and a flat torque curve that begins under 2,000 rpm.
