Compared to cars from BMW's in-house performance subsidiary, BMW M, Alpina's vehicles have more emphasis on luxury, higher torque, and have their own Alpina-style shiftable ZF automatic transmissions instead of manual or semi-automatic transmissions. For instance, regarding the high performance variants of the BMW E60 5 Series, the B5 offers a different take on performance and how to accomplish it. Unlike BMW M's own M5 which has a naturally aspirated, high-revving 5.0L V10, the Alpina B5 uses a supercharged 4.4L V8 which produces similar horsepower and greater torque at lower rpm.
