2020 Mercedes-AMG GT Black Series spotted testing

Mercedes-AMG’s fastest accelerating car yet, the GT Black Series, has begun road testing ahead of its unveiling next year.

Pictures taken by Autocar reader Pedro Lopez show the Black Series will bear a close resemblance to the recently launched AMG GT R Pro, sporting the same prominent rear spoiler and low, wide stance, but will go without that model’s track-oriented winglets and splitters. 

The future range-topping coupé will be beaten only by the limited-run AMG One hypercar when it arrives in mid-2020, AMG boss Tobias Moers confirmed to Autocar at the New York motor show.

Moers said: “It will be the fastest AMG yet, bar the One. Not in terms of top speed, but lap times.

“Driveability is most important but, with balance, it gets good lap times too.”

First confirmed by Moers back in 2016, the Black Series is mooted to receive AMG’s turbocharged 4.0-litre V8 engine in a state of tune offering at least 630bhp.

This is the figure offered by the current most powerful AMG model with that unit, the GT 4-door Coupé. Any growth on that would ensure the Black Series dwarfs the peak output offered by the current GT champions, the 577bhp GT R and GT R Pro (pictured).

It would also edge it towards one of the category’s most radical supercars, the 690bhp Porsche 911 GT2 RS. According to Moers, the Black Series will be “great competition with our close neighbour.”

The GT Black Series’ extra grunt will be accompanied by a more focused chassis and aerodynamic set-up, which may go even further than the track-focused GT R Pro launched at last year’s Los Angeles motor show. That car was designed with uprated suspension and aero upgrades, but received no extra power over the regular GT R.

Such a set-up should ensure the GT Black Series tips the scales at around 1575kg, in line or slightly less than the GT R Pro. 

The 2020 arrival of the GT Black Series will mark a return for AMG’s most extreme moniker after a seven-year hiatus. The last Black Series model was based on the SLS and entered production in 2013.
