ReNNtech Unveils SEC V12 Sledgehammer: A Tribute to V12 Performance

Introducing the ReNNtech SEC V12 Sledgehammer

ReNNtech, the US-based aftermarket tuning powerhouse, has officially announced the SEC V12 Sledgehammer. This limited edition model pays homage to the iconic Mercedes-Benz M120 V12 engine and represents what they claim to be the ultimate evolution of the C125 SEC platform.

The Heart of a Legend

At the core of the SEC V12 Sledgehammer is the M120 V12 engine, renowned for its use in legendary cars like the CLK GTR and Pagani Zonda. This 7.5-liter, naturally aspirated V12 is meticulously hand-built at ReNNtech. It has been reengineered to deliver an impressive output of 660 horsepower and 450 lb-ft of torque, while custom equal-length headers amplify that unmistakable V12 sound.

This design not only enhances its aggressive look but also includes improved cooling systems and revised aerodynamics, ensuring high-speed stability. The flared wheel arches accommodate a set of custom forged wheels, adding to its performance capabilities.
