The AMG GT's swansong is going to be an absolute monster.
Just last week, we caught a new prototype of the long-awaited Mercedes-AMG GT R Black Series being put through its paces in southern Europe during some hot weather testing. Compared to previous prototypes, the new Black Series was sporting some very aggressive-looking hood vents hinting at the high-performance engine lurking under the hood. However, it seems that Mercedes-AMG is testing multiple Black Series Prototypes to test different aerodynamic components.
Spotted at the Nurburgring, this latest Black Series prototype once again features a sculpted hood and massive hood vents seen on last week's prototype, but this one has also been fitted with a ginormous rear wing that will no doubt generate considerable amounts of downforce to keep this monster glued to the track. Look closely, and you can see it's been designed as a double wing.
Elsewhere, the Black Series prototype has the same fender louvers as the GT R Pro and even wider fenders, unless Mercedes is trying to mislead us with the camouflage. The front end also looks more aggressive than last week's prototype, but the rear bumper still appears to be unfinished judging from the stacked quad exhaust pipes and a lack of rear diffuser.
As a swansong for the current AMG GT, the new Black Series is going to be the most powerful variant yet. The hardcore AMG GT R packs a 4.0-liter twin-turbo V8 producing 577 horsepower and 516 lb-ft of torque, which is plenty of power for most people. However, the Black Series is expected to increase the output to over 700 hp, which should make it a true Porsche 911 GT2 RS fighter. That's 70 more horsepower than the GT 63 S Four-Door Coupe, which currently has the most powerful version of AMG's V8 engine. Expect the Mercedes-AMG GT R Black Series to debut sometime in 2020.
