RENNtech Does Mercedes SL65 AMG Black Series

RENNtech is the third tuner to make their own 800-hp version of the Mercedes SL65 AMG Black Series. They’ve done it in collaboration with luxury car dealer Domani Motors of South Florida, who provided the car. So thanks to some fiddling with the ECU and installing a new exhaust system, they managed to extract 805 hp and over 1000 lb/ft of torque.

805 hp does not make that big a difference in performance over the 670 hp standard version, but since it’s now fashionable to get an overpowered Merc SL Black between rich dudes, it makes sense! But from every other point of view it is completely bonkers and pointless.

Performance Package 1 contents include ECU/TCU tuning, Dual Intercooler Pump Upgrade, and RENNTECH Sport Exhaust. This particular vehicle was also equipped with a Transmission Upgrade and 100% Locking Rear Differential from RENNTECH. The RENNtech differential is based on OS Giken’s line of Super-Lock LSD which functions as a traditional open differential in low and normal-load situations, transforming smoothly and gradually up to 100% full lock as loads rise. The Super-Lock LSDs clutch packs make the unit incredibly quiet and smooth, without the kind of chatter usually associated with limited-slip cars.
