To continue the epic battle between the two of the most brutal tuning companies on the market -G-Power and Brabus, now we will compare BMW M3 E92 SK II and BULLIT. Both cars are extremely powerful and expensive, of course, especially the Mercedes.
Let’s start with the less powerful G-Power BMW M3 E92 SK II, which is based on the sports compact executive M3 Coupe. It is powered by the well-known high-revving 4.0 liter V8, which is now boosted to the exquisite 570PS (419 kW) and 565Nm (417 lb-ft) of torque.
The performance is awesome – 4.4 seconds to 100 km/h and just 12.9 seconds to 200 km/h. The top speed is somewhere around 333 km/h. Actually, you can check the tuned M3 doing that in the video below.

Besides the incredible acceleration, G-Power SK II also has incredible deceleration system consisting of 396 mm diameter discs on the front axle with 6-piston calipers and 380mm discs at the rear axle with 4-piston calipers. The high-performance brake system alloys decellerations beyond 1.0g.
Other upgrade is the GM3 RS coilover suspension and Silverstone alloy wheels fitted with Michelin Pilot Super Sport road tires.
The overall price is not calculated, but BMW M3 E92 starts at €68 750 and the “Sporty Drive” supercharger kit is priced at €11 500.
Continuing with Brabus Bullit based on the mighty Mercedes AMG C 63 AMG originally producing 457PS and 600Nm of torque from the most powerful naturally aspirated 6.2 liter V8 in the world. However, Brabus decided that this engine is not good enough and they fitted the small C-Class with enormous bi-turbo V12. It develops 730PS (540 kW) at 5100RPM and 1320Nm (970 lb-ft) of torque from 2100RPM.
The performance – 0 to 100 km/h in 3.9 seconds, to 200 km/h in 10.5 seconds and top speed of more than 362 km/h (225 mph). The car is way more powerful and faster than the G-Power SK II and still it is street-legal.
Brabus Bullit also features a modified 5-speed transmission, a LSD, full aerodynamic body kit, huge brakes and an adjustable rear suspension. The car also has an aluminum hood with ventilation slots and Brabus wheels fitted with high-performance tires.
The interior boasts custom sports seats with carbon fiber covers and carbon fiber elements.
The price for this pleasure is no less than €348 000.
The conclusion is easy – Brabus Bullit rocks!
