MB didn't make the car start in 2nd gear due to torque (big fallacy), it was because there are less tailpipe emissions when the transmission starts off in 2nd gear. Actually, starting off in 2nd gear puts MORE load on the engine's crankshaft.

For better performance, you should modiify you transmission with a 1st gear start controller so it starts off in 1st everytime (like every normal car and all new MBs after 1995).

I've done this to my 560 and what a beautiful difference!
