Back in 2011, the guys from G-Power launched the so-called G-Power GTS SKII "Sporty Drive" system for BMW's GTS M3. It was comprised of a set of upgrades, out of which the most important was the supercharger system.
A G-Power GTS SKII 'Sporty Drive' M3 used to develop 635 HP and was pretty fast: 0-100 km/h (0-62 mph) in 4.2 seconds, 0-200 km/h (124 mph) in 12 seconds and the top speed was 200.7 mph (323 km/h).
Now, the car is even faster. The updated 'Sporty Drive' system now takes the engine up to 650 HP and 630 Nm (465 lb-ft) of torque. Of course, that makes the car even faster, reaching 100 km/h (62 mph) in 4.1 seconds and 200 km/h (124 mph) in 11.8 seconds whilst the top speed remained the same.
In case you're convinced, you should also know that the whole kit costs €23,500 ($30,720) without labor costs.
