Thank you for posting.
Nice showing by the RCF. 2nd place can't be a bad thing.

I don't like the M4 personally, but it's easily the quickest car of that test. How hard was to learn its launch control
? And the i8 looked to finish ahead of the RC-F, and not by a hair, which means in reality the RC-F is last. But still close to all of them. To me though, the RC-F has the best driving position and best interior (design, execution, feel, materials, etc), so I don't care if it's a few ticks behind its more expensive competitors

. That driver either didn't engage LC, or fully disabled TC thinking he was Vettel. Or maybe both. Ha ha. At any rate, not a good driver, and quite embarrassing, especially for BMW. If you can only engage LC with TC off on the new M4, then you just don't use it without knowing what you're doing. My E92 M3 took off like a scalded cat. Not nearly as quick as the GTR, but definitely very consistently. Surprised they didn't do the test again, since it was clearly a blatant driver error. Good for us though
. By the way, which modes are best to launch the RC-F? Sport+ or sport+ expert, and auto or manual? The latter may allow excessive wheelspin, so probably just sport+, no? But manual or auto? And does the ECU allow brake-torquing with SST (smart stop technology)? Not that I'd do that to my car, but just curious if the ECU doesn't kill the power when both pedals are depressed. It supposedly does it only when the brake is pressed last, but maybe also above certain rpm when stopped, to prevent tranny damage. Thx.

Honestly, the M4 might as well have an oil spray in the wheel wells. No stick...no traction.

That's what TC (in M mode) is for. That driver either didn't engage LC, or fully disabled TC thinking he was Vettel. Or maybe both. Ha ha.

This is the 2nd 'drag race' that they've had in England where the BMW comes in DFL to supposedly slower cars...

And that's the problem...you have to completely disable DSC. On most cars...the LC will still modulate wheel spin even with your foot planted firmly on the mat. In the M3/4...it just allows you to lay long patches of Michelin rubber. It's really no different than dumping the clutch and having to feather the throttle in manual cars. Smh...

A bloody shame, but it's a smoke house.

it can put the power down...as shown by its tested and verified 0-60/quarter mile times. but the LC is just trash. a Vette with the same kinda traction control would produce the same results. the question is...why is BMW's LC so hit or miss?

Manual mode in the RC F off the line seems to have better grip for me...enough to make a difference in a comparative run.

. No brake-torquing, correct?
