2004 SL 600 ( in Forbes )

Just consider the V-12: With 493 horsepower and

590 foot-pounds of torque, it'll launch the SL to
60 miles per hour in 4.5 seconds, yet at 80 mph it's barely breathing, only churning at 2,500 rpm; so, unlike other machines that can accelerate this quickly, the Benz is true to its heritage. Smooth power is this car's raison d'être, and it is manifested through luxurious packaging, an unbeatable reputation and excellent engineering.
