The Mercedes-AMG S63 is a gorgeous powerhouse of an executive sedan that isn’t overly flashy or ostentatious. It lets class do the work of grabbing attention as it slips away with its thundering V-8 engine. The team at IMSA, however, wanted to turn things up a notch without getting too showy and created the IMSA S720.
The newest IMSA S720 focuses on the 2018-model-year facelift while bringing forth the same attention to detail and quality as the previous model. Holger Mohr and his team started by giving the Mercedes-AMG S63 a new carbon fiber aerodynamic facelift that keeps right in line with the factory bodywork. Here, the little things make all the difference and that can be seen starting with the new side sills. Up front, new air intakes, grille, and splitter redirects air into the radiators and engine bay. At the rear, a new trunk-mounted spoiler lip works with the lower diffuser and perfectly-integrated exhaust tailpipes to create more downforce.
Making with the pavement on the IMSA S720 is a fresh set of customer-spec CR2 lightweight alloy wheels that reduce rotating mass at the wheel hub for better overall performance. These 21 x 9.0 front and 21 x 10.5 rear wheels are shod in sticky 255/35/21 and 295/30/21 tires, respectively.
Under the hood is where the real fun begins on the IMSA S720. The twin-turbocharged 4.0-liter V-8 engine was outfitted with a new pair of in-house turbochargers, stainless steel downpipes, and catalytic converters. This not only results in more boost but gets all the exhaust gasses out as quickly as possible. To accommodate for the new hardware and turn up the power, the IMSA team upgraded the software for the engine and transmission. The end result is a whopping 710 horsepower (720 PS) and 730 lb-ft. of torque hitting the rear wheels.
As an option, customers can get their IMSA S720 outfitted with a specially-tailored interior.
The new IMSA S720 based on the Mercedes-AMG S63 is currently available for the newly-facelifted 2018-MY vehicle.
