Powering this monstrosity is a modified 1.6-liter turbocharged 90-degree V6 engine from the Mercedes-AMG F1 W06 Formula One car allied with four electric motors outputting a whopping combined output of 1,050 horsepower.
2 2023 Audi R8 GT

3 2014 Mercedes-Benz SLS AMG Black Series
The Black Series badge is the top-most rank given to Mercedes sports cars and the 2014 Mercedes-Benz SLS AMG Black Series is one of the most legendary machines to bear that moniker. The Mercedes-Benz SLS AMG itself is truly special as it was the first car designed and built from scratch by AMG and the Black Series takes it up a notch. This Mercedes masterpiece with gullwing doors has a gracefully euphonious 622-horsepower 6.2-liter V8 engine under its hood which was the most powerful naturally aspirated engine when it came out.
4 2015 Audi R8 Competition
The 2015 Audi R8 Competition can be considered the spiritual predecessor to the now most-powerful 2023 Audi R8 GT as it was the final sendoff given to the first-gen R8.

6 2013-2017 Audi RS5 Coupe
The Audi RS 5 is the high-performance version of the brand’s compact luxury A5 sedan that has been around for a decade now in the American market. However, the current, second-generation, turbocharged, V6-powered RS5 isn’t the greatest of its kind. Unlike it, the first-gen RS5 has a serenading naturally aspirated V8 under its hood, producing an increased 450 horsepower. The first-generation RS5 has a distinct character and delivers an exceptionally enjoyable driving experience, the spirit of which was lost somewhere after its redesign.
7 2021 Mercedes-Benz AMG GT Black Series
The 2021 Mercedes-Benz AMG GT Black Series is the direct descendant and royal successor of the SLS AMG Black Series, which is totally worthy of adorning its crown. Before the arrival of the Mercedes-AMG One, this Black Series monster with a 720-horsepower 4.0-liter turbo V8 was the most powerful and capable Mercedes ever created. A track-tuned suspension setup, extensive usage of carbon fiber, extreme active aero components, and a unique set of tires contribute to sticking this speed demon to the tarmac and rocketing it to 60 mph in under 3 seconds.
8 2019-2022 Audi TT RS
The Audi TT is getting axed after the 2023 model year and this would result in the retirement of the TT RS too. The Audi TT RS can be recognized as a baby R8, and it does deliver a phenomenally fun driving experience in a mini supercar package. Although the latest generation TT RS was launched in 2018, it was the next year it got its winsomely enraging demeanor after a minor facelift. Power comes from a 394-horsepower 2.5–liter turbocharged inline-5 engine and this remarkable sports car is undoubtedly an icon.
9 1999-2000 Mercedes-Benz CLK GTR AMG
Primarily designed as a full-fledged racecar intended to compete in the FIA GT Championship series in 1997, the Mercedes-Benz CLK GTR is a homologation special built in very limited numbers. This supercar is an engineering marvel conceived in just 128 days featuring a carbon fiber tub and powered by a stupendous 622-hp 6.9-liter naturally aspirated V12. Another highlight is the 6-speed sequential manual transmission with a carbon fiber clutch that transmits power to the rear wheels enabling the CLK GTR to charge to 60 mph in 3.3 seconds.
10 1985-1986 Audi Sport Quattro S1 E2
The Audi Sport Quattro S1 E2 is the updated version of the Sport Quattro S1 both of which are rare homologation cars built for Group B rallying.
