Launch Control is VERY picky
My launch control (Race Start) feature seems to be extremely picky for when it will engage. I would say 80% of the time I try it, it says that Race Start is not available. Engine temps are warmed up and at normal operating levels, flat roads, wheel straight, set in race mode, all of the things I know to make it work are in order.... Occasionally it will work.
I have been at a stop light, engaged race start to see if it would let me and been successful, then let off the throttle to wait for the green light. When the light turns green moments later I try again and it will not engage.
Is this normal? It is very frustrating!

Have you checked the manual? On the 2021 cars, it’s 1,000 miles before it should be used (per the recently-released owner’s manual), but there’s no mention of whether it will engage earlier in its life. Regardless, it doesn’t seem wise to attempt it beforehand.

Might have been a software glitch. Once the brake pedal was mentioned, I was CERTAIN that must have been it... user error.
I went out and put the brake to the floor multiple times. Same problem. I had only tried launching in race mode. Then tried in Sport+ and it worked. Went back to race mode, worked. Has been working reliably ever since.
I bet it was more my fault than the car. Glad its worked itself out. Now I can't stop launching.

Also Accelerator to the floor... If it's not all the way down, you won't engage either. Brake and accelerator have to be firmly down. I used to have problems, but after that 100% success with launches. Good luck!

As the OP I feel like I should chime back in. After owning the car for a year, my issues were user error. After learning the car, Launch Control works when and how its supposed to. Temps must be up, proper pressure on pedals etc. Best vehicle ever made.

Thanks for coming back around. I guess I'm also in the same boat that you were in (new owner, sometimes working, sometimes not). Is it really as simple as everyone says? Just mash the brake then mash the gas? (With temps at right level)

Mercedes Benz AMG GLC 63s
Mine become far more picky when the clutch was getting worn in the GLA A45 AMG, my GLC63s with 80,000ks is still ok yet I almost never use it. Too worried about having to replace that gearboxes clutch pack due to what it is.

Okay quick question on the tttopic, My buddy has an Audi RS7 and it is now tuned. Not sure brand tune but my buddy said the tuner guy told him Audi are set from factory with 100 launches programed and after that will not work. He reset counter to 0. My question is does 2020 E 63s have a launch counter and a launch Max. limit?
