This tuned version RENNTECH Mercedes SL65 AMG Black Series is one mean piece of machinery. As the dyno test video will show this hardtop coupe is able to spit out no less than 865 HP and 1,000 lb-ft of torque, which means 135 HP and 263 lb-ft over the standard version SL65 Black Series.
The power boost was achieved by fitting the RENNTECH Mercedes SL65 AMG Black Series with an upgraded dual intercooler pump, an optimized transmission and an 100 percent locking rear differential.
The RENNTECH Mercedes SL65 AMG Black Series has also received revised engine electronics and pricing for the modifications mentioned above starts at 16,390 USD.
