G-POWER G4M Bi-TURBO Cabrio
Powered by a twin-turbocharged 3.0L inline-six engine producing 523, the standard BMW M4 Competition xDrive Convertible can sprint from 0 to 60 in 3.6 seconds. We'd imagine the G-POWER G4M Bi-TURBO Cabrio, which uses it as a base, is considerably faster. Through a combination of software, a new intake system, a new Deeptone exhaust, and ECU tuning, it coaxes 700hp out of the same engine. While performance numbers haven't been published, the G4M does look the part, with a GP-Venturi carbon hood, GP-Shuriken carbon front corners and grille, and GP-Hurricane RR forged wheels. G-POWER's G4M upgrades can be purchased separately or as a complete package.
