SL/R230: Car & Driver comes clean
"The RENNtech SL600 finished in sixth place, but that doesn’t warrant a sneer, considering it’s a wind-in-your-hair luxury roadster that was up against some very serious sports cars. A stock Mercedes-Benz SL600 cranks out a remarkable 493 horsepower and a neck-snapping 590 pound-feet of torque, and after RENNtech’s head honcho, Hartmut Feyhl, gets through with his 15-grand engine massage, those numbers soar to an astronomical 640 horses and 770 pound-feet. On its best run at Michigan speedway, this souped-up SL600 ripped from 0 to 60 mph in 3.9 seconds, only 0.2 second behind the winning Hennessey Venom’s performance."
