Are you sure the something he releases isn't just the brake? i.e. He builds revs to 2,500 and then releases the brake? MY23 Panamera E-Hybrid

I think I saw a video about the Audi system and launch control has 10 goes and then it’s new gearbox time.

Having watched it a few limes I'm thinking he must. I would have thought the vehicle wouldn't allow you to rev with the left foot on the brake but I can't see him doing anything else. Even the chapter on the video is entitled "launch control" so it just made me curious. Anyone willing to try it? FFRR SDV8 Autobiography |

Many Audi automatics and some BMW's I've driven if you have left foot on the brake, disengage drive and allows revs to rise to a predetermined level to allow turbo's to be spooled etc. When the brake is release the gearbox then transmits the drive and youre off. BMW i3 Electric Car

If the engine and box are nice and warm and you have a standard auto box then holding it on the brake will not harm the box, it will overheat rapidly if left there for any time but what he did is fine...

Do the same thing in reverse and once you get tires all smoking haul it into drive you will get the familiar black J strips on the pavement. Occasional you will get the engine to run backwards which it doesn't do well.
