RENNtech SEC V12 Sledgehammer due in 2027 with Pagani Zonda power

US-based aftermarket tuner ReNNtech has revealed the SEC V12 Sledgehammer. This limited edition model is a tribute to the legendary Mercedes-Benz M120 V12 engine and “the ultimate evolution of the C125 SEC platform”.

The M120 V12 engine is the unit that was used in legendary models like the CLK GTR and Pagani Zonda. The 7.5-liter, naturally aspirated V12 is hand-built at ReNNtech. It is reengineered to produce 660 hp and 450 lb-ft of torque, while the hand-built equal-length headers deliver a signature V12 sound.

This legendary motor is wrapped in an equally iconic Mercedes SEC C126 body, which has been modified to give it a wider stance. It also gets enhanced cooling and revised aerodynamics for high-speed stability. The flared wheel arches house a set of custom forged wheels.

ReNNtech is building only 12 examples of the SEC V12 Sledgehammer. The first customer cars are expected to arrive in 2027.
