Apologies if this has been asked before.

From research I see that bmw claims 2.9s but some owners claim it goes faster. Thought I'd ask some m8 owners who are into track and dragy. I'm a g82 owner looking to upgrade and wanting more. I drove the m8 yesterday and the v8 and overall experience is night and day

Thanks

Nobody has replicated 2.5 on a stock car afaik.
You can get close with a tune…

I've seen a few videos of people getting high 2s but never 2.5, I think it would be tough if not impossible on a stock car.

Even with rollout, that's far too optimistic. Neither of my M8s can manage that with or without rollout even when tuned. The fastest of my recent BMW V8 Ms (that use the S63TU) was my 2020 M5 which repeatedly managed 0-60 in 2.57s (no rollout) and the 1/4 mile in 10.33s with just a JB4 piggyback. With a similar setup, my M8 GCs are in the 2.7s to 60 and 10.5s in the 1/4 mile (that's per Dragy since I don't frequent drag strips much anymore). The Coupe can likely do better since it weighs a bit less.

EDIT - Oops. I misunderstood what they meant by rollout. They're actually shaving time off the launch - 0.2 seconds in this case as documented further down in the road test review. Fluffy, indeed.

Original post:
That's what I thought too since that's their standard operating procedure for 0-60 times. But in the linked story they claim to have just used factory launch control:

"Set it to Sport mode, make sure the transmission is in its most aggressive setting, and Hulk-smash the brake first and then the gas. A notice flashes in the IP that launch control is engaged, and when you release the brake, the M8 smashes you back. It blasts through 60 mph in just 2.5 seconds and clears the quarter-mile in 10.7 at 129 mph. Just 15 seconds from stopped, it's at nearly 150 mph."

I concur here too sir.... magazine prepped surfaces and premeditated in nature vs real world mash and go.

C&D definitely makes an owner feel good/better though

Got it. I'm in there, too—same name as here—a few ticks above you but that's with a tune. Your DA was meh; very minor gravity assist. Do you have any mods—related to perf or otherwise?
