RENNtech has unveiled the C74 Konzept with the new C74 Widebody Aerodynamic Package.

Based on the Mercedes C63 AMG, the C74 Konzept features various carbon fiber accessories (a widebody kit, rear spoiler, front splitter, and rear diffuser) and three-piece forged aluminum wheels with Nitto INVO performance tires.

Under the hood, the 6.2-liter V8 engine has been outfitted with a revised ECU, a modified air intake (with high-flow air filters), an upgraded camshaft, and new cylinder heads. Thanks to these changes, the V8 produces 605 hp (451 kW / 613 PS) and 555 lb-ft (752 Nm) of torque. This enables the car to run the quarter mile in 11.4 seconds, at 126 mph (203 km/h), and hit a top speed of 204 mph (328 km/h).

To ensure the car remains planted, the tuner installed an adjustable sports suspension, a limited slip rear differential, high performance brakes, and carbon fiber stabilizer bars.
