The limited edition and already sold out BMW M4 GTS is getting a significant power upgrade from the renowned tuning shop G-Power. With a series of software and hardware upgrades, the German powerhouse has given the M4 GTS a power bump from 500 horsepower to 615.  The tuning has implemented numerous mechanical modifications to lift power, including a customized turbine wheel and housing.

Additionally, a more free-flowing exhaust was needed to reduce backpressure so a set of stainless steel downpipes without catalysts have been fitted.

The ECU map with the Bi-Tronik 2 V3 kit helped deliver the 615 hp figure. Torque has also been dramatically increased from 600 Nm (442 lb-ft) to 760 Nm (560 lb-ft).

When launch control is active, the G-Power BMW M4 GTS can now sprint from standstill to 100 km/h (62 mph) in a mere 3.6 seconds and continues onto over 320 km/h (200 mph) thanks to the removal of the stock electronic speed limiter.

The company also offers a set of lightweight 21-inch forged wheels for the car and for owners not wanting to mess with the engine’s internals, an ECU-only tune is offered, resulting in 575 hp and 740 Nm (545 lb-ft).
