That puts the whole "RC-F is slower than IS-F" debate to rest. We knew it all along (well, except a few bitter people). If the RC-F had both I/E like the IS-F, margin would have been bigger.

With automatics from a roll?
I have been driving a 6 speed manual for 12 years so I agree first hand, it takes a great degree of skill to launch and shift fast (especially in a high strung peaky car), but I am not sure if I can say the same thing about automatics.

From personal experience, I can say this:
H/I/E IS-F = Stock RCF 2nd-4th gear
Both cars went from a roll in 2nd and IS-F started at the rear bumper and stayed there till 4th gear. Stock RCF was quick! I could not gain on it 1 inch.

The next gen engine is amazingly powerful. It was designed for response, sound, and continuous acceleration, even above 7,000 rpm.
The ISF just does not have the same pull. Owners with experience in both cars should not be surprised. We also knew the car was modeled after the CCS-R--a faster ISF. Lastly Yaguchi San said the new F would exceed the capabilities of its predecessor.
Yes. Both Fs are remarkable machines in the hands of skilled drivers.

Why is this a big deal? The RCF is a newer F, no chance the guys at lexus will make it slower than the older gen F.
And btw, I own a bone stock RCF and a modded (loud exhaust ISF) tried to race me, and got murdered badly.

If the RCF is that fast, one can only imagine how fast an M4 is if it kills the RCF in a straight line. And the new C63 looks like it's even faster. Every generation can only be better than the last.

. The M4 does not "kill" the RCF. Here again the M4 runs very inconsistent times. I'll wager the RCF in a comprehensive performance run against the M4 on a track or closed circuit with much more than straights will take the flag more often than not.

The RCF is not as raw as my 2012 ISF was. While I miss some of that, the RCF delivers in ways the early car simply could not--it is a combination of brute force and elegance. I am just glad that I was able to get Lexus' next gen V8. This may very well be one of the last great V8s that we will see in this class of car.
