The Brabus 930 is the aftermarket specialist’s most powerful supercar ever. This shouldn’t come as much of a surprise, considering it’s based on the Mercedes-AMG GT63 S E Performance, which was the most potent AMG ever when it debuted two years ago. Brabus has cranked up the car’s engine and added a body kit that helps the hefty plug-in hybrid sprint to 62 miles per hour in just 2.8 seconds.

Under the bonnet is a modified twin-turbocharged 4.0-litre V8 engine. AMG GT63 S E Performance features new Brabus-designed turbochargers with larger compressors and additional reinforcement. Each cylinder receives its own Brabus PowerXtra control module, with new maps adjusting the injection and ignition.

The modified Mercedes powerplant works with the hybrid drive’s electric motor to produce a combined output of 917 bhp and 1,143 pound-feet of torque. Engine output increases by 86 bhp and 74 lb-ft, but Brabus leaves the electric motor in its stock form. The car has a top speed of 196 miles per hour (316 kilometres per hour).

Brabus also upgrades the exterior with its various carbon components that enhance the car’s aerodynamics, available with a glossy or matte finish. At the front, the AMG GT63 receives a front spoiler, caps for the large air intakes, and a more breathable grille. The tuner also fits the car with its Monoblock Z Platinum Edition 10-spoke wheels, which measure 21 inches on the front and 22 on the rear. They are wrapped in Continental SportContact 7 rubber.

A carbon diffuser insert at the back complements the four 3.5-inch titanium/carbon tailpipes. The stainless steel exhaust from Brabus includes actively controlled butterfly valves that alter the exhaust note, which consists of a quiet “Coming Home” mode and a more raucous “Sport” one. Brabus also adds its Airmatic Sport Unit plug-and-play module that can lower the ride height by up to 20 millimetres (0.8 inches) depending on the drive mode.

The Brabus 930 costs €323,435, excluding the 19% VAT (£281,000 at today’s exchange rates), and the specialist will convert the GT63 S E Performance that you already own. The car comes with the three-year or 62,000-mile Brabus Tuning Warranty too.
