New Mercedes-AMG GT Black Series 2021 detailed: Flatplane engine Affalterbach's most powerful V8 yet

Mercedes-AMG has officially revealed the latest addition to its Black Series flagship line-up, the GT coupe, which features its most powerful V8 engine yet.

A thoroughly revised version of Mercedes-AMG’s ubiquitous 4.0-litre twin-turbo petrol unit (including a flatplane), the engine in question punches out 537kW of power from 6700-6900rpm and 800Nm of torque from 2000-6000rpm.

Just like the ‘regular’ GT variants, the Black Series exclusively sends drive to its rear wheels via a seven-speed dual-clutch automatic transmission, although the latter is reinforced.

This combination helps the GT Black Series sprint from a standstill to 100km/h in 3.2 seconds while on the way to 200km/h in less than nine seconds and its top speed of 325km/h.

Racecar inspiration isn’t limited to the engine bay, as the GT Black Series has coil-over suspension with adaptive dampers and manually adjustable anti-roll bars and camber.

Predictably, a carbon-ceramic brakes package is also on hand to wash away speed with ease, while light but strong carbon-fibre is used extensively throughout the chassis to increase bodyshell stiffness.

The Black Series well and truly stands out from the GT crowd with its aerodynamically honed exterior redesign, which is highlighted by the vented bonnet, front wheelarch louvres and double rear wing.

Inside, the GT Black Series is upholstered in black Nappa leather and Dinamica microfibre with orange stitching, while matte carbon-fibre trim features prominently. Naturally, bucket seats are an option alongside four-point seatbelts, a fire extinguisher and a roll-over cage.

It’s not yet known how many examples of the Black Series will be heading to Australia, but when it arrives early next year, expect it to be priced well above the GT's current flagship, the $453,200 (plus on-road costs) R Pro.
