Renntech will be showing their C63-based AMG Mercedes C74 Konzept car at the SEMA auto show. Renntech has put on a very aggressive wide body kit on the Merc and have tweaked the engine to produce even more horsepower.
The body kit includes a carbon fiber front lip, a spoiler and a rear diffuser. The car rides on 19 inch wheels in the front and 20 inch wheels in the back. The back wheels are 11 inches wide and are matted to 305-series tires, making the rear track of the car 74 inches, hence the name. The tweaked engine in the Renntech C74 now produces a massive 605 horsepower and 555 pound-feet of torque.
The Renntech C74 Konzept packages start at $11,950 and can reach upwards of $30,000.
