RCF vs old C63 vs E90 M3 vs M4 vs C63S
Cool video, thanks for posting!
The old C63 sounds like a beast. I love that sound. The RC F has that induction/airbox noise and needs a little more out of the tailpipes, which is why an aftermarket exhaust really helps the sound out. As far as quickness, it's about what I expected. Front engine, rear will drive cars that have a ridiculous amount of torque will always have trouble getting off the line, which is why the magazine racers that fall in love with HP/Torque numbers need to get the full picture. The C63s are great roll racers.
Not that we need any affirmation for buying our cars, but look at the depreciation on those C63s... and we all know that repair and reliability is a thing with zee Germans. All nice cars, but I definitely bought the one that I wanted. The only German car I can ever see myself buying again starts with a P.

In a straight line, RCF seems very close with the old C63 AMG. The Euro RCF compared to the NA versions is also down by 18 PS (15 HP) due to stricter emission standards.
C63 has a lot more low end torque, which helps in this format. If I were racing such a car, I would go manual mode and start in the powerband at around 5500 - 5800 rpm in 2nd gear as opposed just hammering it in D like in the video. Time to downshift in D, slippage and torque deficit both hurt the RCF out of the gate.

??? What does engine torque have to do with launching? What you're saying is either the engine is down on power OR the gearing in the car isn't focused on quick launches. Torque is a useless number. Power is everything, and gearing focused on what you want to achieve with the right amount of power is unbeatable. Torque at the crank is meaningless. Torque at the wheel/ground interface is everything and that's fully manipulated by the car's gearing unless it's direct electric motor drive.
So, is the gearing too tall for a good launch? This is the only place final drive ratios matter. Once you're into the meat of the engine's powerband, final drive is inconsequential as long as you can stay in the meat of the powerband. This is pretty simple mathematics.

I agree. It is more about how our transmission acts in D mode. It does not get to the best gear and not quick enough, which is why I use manual with sport+ just be in the right gear at around 5500 - 5800 rpm for maximum throttle/initial acceleration. 2nd gear at 50 mph is my favorite acceleration run especially merging on to highways etc.

Yes, that is true. The torque converter is not locked in D mode regardless of sport+. Only in manual with sport+, the torque converter is locked preventing slippage. Coming from manuals for 18 years, manual is the only mode I use.

I still don't know why he would use 3rd gear at 50 mph. Like I said above, 2nd gear goes to 75 mph and is the perfect gear for instant power.

A little surprised by the old C63...wow.
