The fourth-generation Alpina B7 Sedan is a luxury flagship with a gasoline heart, built for quiet speed and long motorway days. This page explains that generation’s character rather than listing every version.
The Alpina B7 engine in this generation is gasoline throughout, so throttle response stays smooth and ready when you need to merge or overtake. Treat the powertrain as a refined package: the transmission and drivetrain keep the sedan calm in town and composed at higher speeds.
