In their quest to modify every new BMW known to man, G-Power came across the M4 Convertible and pushed its power up to epic proportions.

While the vast majority of petrolheads agree that BMW’s 431 PS (425 HP), turbocharged 3-0-litre convertible is a balanced package, there are some who might consider the figure inadequate. That’s where G-Power comes in, always prepared to transform the potent drop-top into a monstrous super-machine.

Decades of experience determined the German tuner to extract every last drop of latent potential from BMW’s model, offering three bumped-up settings that would satisfy even the most pretentious customer.

G-power starts easy at first, implementing its Bi-Tronik 2 V1-ECU to make the car deliver no less than 520 PS (513) and 700 Nm of torque. Impressed? Well, it’s not over yet because the company can push the final output to 600 PS (592 HP) and 740 Nm – which requires additional hardware and software upgrades. In order to achieve this level of performance, G-Power completely modified the turbochargers, beginning with the bigger, lighter wheel and finishing with the housing.

The end result is an automobile that can leap of the line, from 0 to 100 Km/h (62mph), in 3 seconds and won’t stop accelerating until it reaches its 320 Km/h (199mph) top speed. The bespoke, ultra-lightweight exhaust system’s note will further enhance the vehicle’s grunt, as G-Power says it has put a lot of heart in creating a melodious soundtrack for the convertible.

To ensure the M4 will maintain a perfect road manner – despite the additional power – a set of fully adjustable coil-overs and a set of 21-inch HURRICANE RR rims complete the package.
