One of the most extraordinary M3s ever produced was the 2011 factory-built BMW M3 GTS . The vehicle had racing bucket seats, a roll cage, lightweight body panels, carbon aerodynamic components, titanium exhaust, and six-point seatbelts.
Two of the company’s most expensive M3s were the BMW M3 GTS and its brother, the M3 CRT. Only 150 of the M3 GTS’s units were produced, while only 67 of the M3 CRT’s were made the following year. The S65 4.4-liter V-8 engine, which has 450 horsepower and 324 lb-ft of torque, was installed in both models by BMW.
However, G-Power supplied the Sporty Drive TU supercharger system that improved the performance of the vehicle, claiming to be the only BMW tuner with an update for the S65 engine. With the addition of a lightweight, 100 cpsi metal catalytic converter exhaust system, G-Power was able to lower the exhaust backpressure to a setting that was optimal for the SK II supercharger.
The astounding power boost produced 650 horsepower and 480 lb-ft of torque. The M3 GTS acceleration ‘s time to reach 62 mph decreased from 4.4 to 4.1 seconds, and its top speed increased from 180 to 200 mph.
