News: Double clutch like a speed racer

Double clutching was born out of necessity to help ease gear transitions and prevent clutch wear.

They've since changed the transmission and the double clutch technique is now reserved for a more deliberate driver looking to add finesse to his acceleration.

This is a skill test. In effect, it's auto racing 101.

If you pass, you can feel confident test driving the most expensive cars on any lot.

If not, that's fine. It's why Mercedes makes an automatic transmission roadster.
