You need to try the petrol version. To date I have only ever tried the car in standard auto and it takes off like a rocket if needed.

If you want to experience real Launch Control try it on a Porsche 911 with a pdk gearbox. I did it with an instructor, left foot on the brake. rev the engine to 7000 rpm and take your foot off the brake. You can get up to about 100mph and stop again in about 10 seconds. I did it once and felt physically sick and had to get out of the car in case I threw up. How the F1 guys cope with faster than this it I can't imagine. 3 x FL1 2 manual + 1 auto

Pull up to a stop. Flick on the auto handbrake Take foot off brake and on to accelerator. Floor it! Car leaps from standing start. I've had a chance to think about why this has such a big affect on standing start acceleration. I noticed when i took my foot off the brake once the Electronic Hand Brake is applied that the rear would "haunch" down. For efficiency purposes the gearbox is uncoupled when at a stand still and this would appear to be linked to having your foot on the brake. With hand brake applied and foot off brake the gearbox selects a gear anticipating it's about to drive off. This also means the turbo will begin to spool as increased load at idle would increase exhaust gases. I'm also certain that due to the nature of the dual clutch auto gearbox that there is some electronic retardation, under normal operation to allow the gearbox to idle disengaged to engaging a gear on standstill and driving off. That's my theory cause whoa, what a difference.

Drive along gently at 20kmh and with your left foot gently touch the brake pedal, not enough to apply the brakes, you will feel the car slow and the engine die, applying the brakes, or more rightly the electronic signal received from the switch cuts the engine torque to allow 'better' braking.
