After they upgraded the already impressive BMW M3 and M4 models, the tuning specialists over at G-Power decided to focus their attention on the BMW M4 GTS. The car received the company’s own B-Tronik 2 V3 upgrade, which includes a remap of the initial engine control unit in order to enable better fuel management, sparking and boost.
The upgrade also involved removing the speed limiter, which means that this car can now reach a top speed of over 200 mph. The engine is good for 615 horsepower and 560 pound-feet of torque, and this represents a 115 horsepower and 118 lb-ft of torque increase when compared to the stock figures. This special BMW M4 GTS can do a 0 to 62 mph sprint in just 3.6 seconds, and it runs on a superb set of 21” wheels.
