G-Power
DE Aresing · Founded 1983
Supercharged, big-power BMW M cars and the odd hypercar.
The story
The Grommisch family established G-Power in 1983 in the Aresing area of Bavaria, tracing its performance work back to the early 1970s. The company is most associated with record-setting BMW M cars, including the M5 Hurricane RRS that reached 372 km/h, briefly making it the world's fastest production-based sedan. G-Power focuses on engineering quality over volume, producing a small number of complete vehicles alongside a broad parts catalog.
