Cruising in a sleeper.
Even though the Mercedes-AMG SL 65 Roadster is an AMG model, it often slips under the radar as a boulevard cruiser. The team at VÄTH is making it into a real asphalt-ripping machine with its new upgrade program for the mighty V-12 engine and its chassis.
The hand-built, twin-turbocharged 6.0-liter V-12 engine of the Mercedes-AMG SL 65 Roadster has more than enough power right off the bat, but VÄTH thought it needed an extra boost. The team at VÄTH installed their V65 tuning kit which includes a new software tune, top-speed limiter removal, new intercooler, and a high-flow air filter.
The end result of the upgrade is 700 horsepower. To prevent the drivetrain from exploding, the torque was electronically limited to 737 lb-ft. instead of the possibly 847 lb-ft. This also comes with a top speed that’s pushed back to 202 mph.
Customers that want to show off their more powerful V-12 engine can opt for the VÄTH stainless steel muffler. The valve-controlled muffler comes with a wireless remote and provides three different levels of sound from the quiet to the blaring.
The next step was the chassis. Here, VÄTH installed their new lowering setup for the factory ABT sport chassis. This not only reduces ride height, but adds a sportier, more athletic touch without affecting the overall comfort.
From there, VÄTH installed a new set of in-house, three-piece forged wheels on the Mercedes-AMG SL 65 Roadster. The lightweight wheels have a black and polished finish and measure 10.0 x 20 and 12.0 x 20 at the front and rear with sporty 265/30 ZR20 and 305/25 ZR20 tires.
The full VÄTH Mercedes-AMG SL 65 Roadster upgrade program is currently available. Customers can pick and choose the upgrades they desire or order the entire program for their sports car.
