Back in 2011, BMW introduced the M3 CRT (Carbon Racing Technology), a limited edition of the M3 sedan, which brought weight savings of 45 kg over the standard model. BMW built only 67 units, each powered by a 4.0-liter V8 engine generating 450 hp (331 kW) and 440 Nm of torque.
The M3 CRT was capable to accelerate from 0 to 100 km/h (62 mph) in just 4.4 seconds and had a top speed electronically limited at 290 km/h or 180 mph. The BMW M3 GTS made its debut in 2009 and was a track-focused version of the M3 Coupe.
The M3 GTS was powered by a 4.4-liter V8 that delivered 450 hp and it could sprint from 0 to 100 km/h (62 mph) in 4.4 seconds, while top speed was 305 km/h or 189.5 mph. The V8-powered M3 is now history as BMW introduced the new M3 model that is powered by a 3.0-liter high-revving in-line six-cylinder engine that generates 431 hp and 550 Nm (406 lb-ft) of torque.
For those who are still in love with the predecessor, G-Power offers the strongest version of the S65 V8 high-revving engine of the M3 CRT and M3 GTS. Thanks to the supercharger systems based on the radial superchargers developed by ASA Kompressor and the adaption of the engine to forced induction, the total output delivered by the V8 is an impressive 650 hp and 630 Nm of torque.
In addition, there is a new all-titanium exhaust system made by G-Power, that delivers the necessary reduction in exhaust back pressure.
As a result, the G-Power M3 GTS and M3 CRT accelerate from 0 to 100 km/h (62 mph) in 4.1 seconds, to 200 km/h (124 mph) in 11.8 seconds, while top speed is 323 km/h or 200.7 mph. Pricing for the 650 hp G-Power SK II supercharger system for the BMW M3 CRT/GTS is 23,500 euros (excluding tax) plus installation.
