"The BMW M4 Competition xDrive Convertible is already a heavy hitter straight out of the factory. With its twin-turbocharged 3.0-liter inline-six engine delivering 523 horsepower and a 0-60 mph time of 3.6 seconds, it's no slouch. But in true tuner fashion, G-POWER decided that "fast enough" wasn't good enough. Enter the G4M Bi-TURBO Cabrio, a reimagined version of the M4 Convertible that cranks output up to an eye-watering 700 horsepower - while dressing the drop-top in enough carbon to make supercars nervous."
"The G4M doesn't just announce its presence with horsepower - it looks the part, too. The most noticeable change is the GP-Venturi carbon hood, designed to both reduce weight and improve cooling. GP-Shuriken carbon front corners and grille add a more aggressive edge, while also enhancing airflow. These upgrades are subtle enough to maintain the M4's recognizable silhouette but bold enough to separate it from the crowd."
The G4M Bi-TURBO Cabrio increases the BMW M4 Competition xDrive Convertible's output from 523 horsepower to roughly 700 horsepower through intake changes, a Deeptone exhaust, detailed ECU tuning, and software refinements. The tuning yields significantly stronger throttle response and greater punch through the rev range, suggesting acceleration will improve well beyond the factory 0-60 mph of 3.6 seconds. Weight and cooling benefits arrive via GP-Venturi carbon hood and GP-Shuriken carbon front corners and grille, while GP-Hurricane RR forged wheels reduce unsprung mass and support the more powerful drivetrain. Exterior upgrades combine performance and aggressive visual presence.
