The Mercedes-AMG S63 is an amazing powerhouse of an executive sedan that isn’t overly flashy or ostentatious. It lets the class do the work of catching attention as it slips away with its thundering V-8 engine. IMSA team, however, looking to turn things up a notch without getting too showy and made 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 began by giving the Mercedes-AMG S63 a new carbon fiber aerodynamic facelift that keeps right in line with the factory bodywork. Here, the small things create all the difference and that can be seen beginning with the new side sills. Upfront, new air intakes, grille, and splitter channelize 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 make more downforce.


Building contact with the pavement on the IMSA S720 is a fresh set of customer-spec CR2 lightweight alloy wheels that minimize 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 equipped with a new pair of in-house turbochargers, stainless steel downpipes, and catalytic converters. This not only results in enhancing boost but makes all the exhaust gasses out as quickly as possible. To accommodate the new hardware and turn up the power, the IMSA team enhanced the software for the engine and transmission. At the end outcome are massive 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.
