Renntech’s Ambitious Project
The Renntech SEC V12 Sledgehammer is a striking reinterpretation of the iconic Mercedes-Benz C126 SEC. This project showcases Renntech’s expertise in automotive tuning, a brand that has been enhancing Mercedes vehicles for over 35 years.

Powertrain Specifications

- The original Mercedes M120 V12 has been modified to a staggering 7.5 liters.
- This upgraded engine now delivers an impressive 660 hp and 650 lb-ft (881 Nm) of torque.
- Production will be limited to just 12 units worldwide, making it an exclusive collector’s item.
Engine Performance
To ensure the SEC V12 produces an exhilarating sound reminiscent of a Pagani, Renntech has engineered custom equal-length headers. While the exact transmission details remain undisclosed, it’s expected that power will be routed solely to the rear wheels, enhancing the driving experience.

Aggressive Custom Bodywork
The Renntech SEC V12 Sledgehammer features a bespoke body kit that significantly alters its visual profile compared to standard models from its era. The design includes:

- Revised front grilles
- A distinctive hood
- Wider front and rear quarter panels
This custom bodywork not only enhances aesthetics but also contributes to improved aerodynamics.
Upgraded Wheels and Brakes
In addition to its eye-catching design, the Sledgehammer will be fitted with new forged wheels and upgraded aftermarket brakes, ensuring both performance and style.
Interior Customization Options
While interior images have yet to be released, prospective buyers can expect a range of bespoke cabin configurations. Renntech is likely to offer a variety of materials and finishes, allowing each owner to personalize their vehicle to match their preferences.
Availability and Pricing
Although pricing details are currently unavailable, Renntech has announced that the first customer car is expected to be completed in 2027.
