1992 Mercedes-Benz 600 SEL Restomod Has 615 HP From 7.2-Liter V12

Posted on

Renntech is one of the top names in modifying Mercedes-Benz products. When the company claims to build the perfect 1992 600 SEL, it’s worth paying attention. The result is the S76R, and the sedan has the company’s most powerful naturally aspirated V12 ever.

Renntech started with the Mercedes M120 6.0-liter V12. It drills and drives the powerplant to a massive 7.6 liter displacement. New internals include a titanium connecting rod and an AMG camera. There are ported heads, honeycomb valve springs, and titanium holders. The thirty-pound fuel injector feeds the gasoline.

The engine breathes through Renntech’s own design for the air box. Exhaust gases pass through a stainless steel header of the same length to the sport catalytic converter and quad muffler. Polished stainless steel exhaust tip sticks out from behind.

With all this work, the V12 makes 615 horsepower (459 kilowatts) at 5,500 rpm. Peak torque of 703 pound-feet (953 Newton-meters) is available between 4,250 and 4,500 revolutions. This power allows the sedan to hit 60 miles per hour (96 kilometers per hour) in a low-5.0 second range. The top speed is 155 mph (249 kph).

As the 1992 SEL 600, this sedan usually comes with a four-speed automatic. Renntech replaced this with an upgraded five-speed car from the 1996 model year. Plus, the tuner added a Giken OS limited slip differential.

Beyond the engine overhaul, Renntech provided the S-Class restomod carbon-ceramic discs measuring 15.83 inches (402 millimeters) up front with six-piston calipers and 14.17 inches (360 millimeters) with four-piston plugs at the rear.

The suspension consists of shorter coil springs, and Renntech added a second-generation adaptive damping system.

The tuned 600 SEL looks almost stock on the outside. Renntech added its own front splitter, trunk lip spoiler, and louvered side molding. There is also an AMG ground effects kit. The sedan uses one-time forged aluminum alloy wheels measuring 19 x 9 inches at the front and 19 x 10.5 inches at the rear. The company is pairing Michelin Pilot Sport 4 S tires.

Renntech kept the interior looking original but added some modern enhancements. There was a new chair, and diamond stitched embroidery covered it. Most of the trim is carbon fiber, and the headliner is Alcantara. The company replaced the original bench seat with two individually adjustable seats. Stereo is now compatible with smartphones.

Renntech built the S76R as a one-of-a-kind, but you can also take it as a proof of concept. The company takes a commission for more. The company announcement does not include pricing details. This seems like one of those cases where if you have to ask, you can’t afford it.
