The latest creation of ReNNtech is the C74 Konzept, which is based on Mercedes-Benz C63 AMG.

The project features a lot of carbon fibre such as – rear spoiler, front splitter, and rear diffuser, also including a widebody kit. The car stands on huge 3-part forged alloys fitted with Nitto INVO ultra-performance tires.

You already know about the 6.2 liter naturally aspirated V8 engine from Mercedes, which turned to be incredibly successful with its 457hp at 6800RPM and 600Nm of torque. However, ReNNtech boosted the engine to the mighty 605hp (451kW) and 752Nm (555 lb-ft). The results are thanks to a re-mapped ECU, CAI with high-flow air filters, an upgraded camshaft, and new cylinder heads. All new power means that C74 run ¼ mile in 11.4 seconds at 203 km/h (126mph) and the top speed of the car is 328 km/h ( 204 mph ).

Furthermore, ReNNtech installed an adjustable sports suspension, a limited slip rear differential, high performance brakes, and carbon fiber stabilizer bars.

The tuning package starts at just $11 950 (€8 580).
