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.

Aerodynamic Enhancements and Design
The SEC V12 Sledgehammer isn’t just about raw power; it’s wrapped in a modified Mercedes SEC C126 body that features a wider stance. 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.

Exclusive Production Numbers
ReNNtech plans to produce only 12 units of the SEC V12 Sledgehammer, making it an exceptionally rare offering in the automotive world. The first customer deliveries are anticipated to commence in 2027.
