The Alpina B7 Sixth Generation Restyling is a luxury performance sedan. You get a high-output gasoline setup and an automatic drivetrain aimed at long-distance comfort with more pace than a typical executive car.
One Alpina B7 engine example is the 4.4 AT sedan: gasoline, automatic, and all-wheel drive. That powertrain is built for effortless cruising, so you get a relaxed drivetrain that still feels stronger than a typical luxury sedan when you need a clean, quick overtake.
