RC F automotive reviews thread

We should all know by now that the 0-60 time is a grip issue only , nothing else. You could add another 200 hp and the Merc would probably get slower than Rc-F up to 100 mph. Or simply make it AWD.

This has been posted like a bazillion times. You are not looking hard enough since M4 has weighed about 3610 lbs in many tests (with DCT). For example, the RC-F vs M4 test by Motor Trend.
Again, where is your over 3600 lb figure? You're also guessing that the items he removed (a manual and trunk net LOL) and some gas will get you to the reported 3540..right (but does the BMW reported curb weight actually include FULL gas - go check). Yes BMW misled, but they also countered with understated power by the absolute majority of dynos out there to show this car is delivering about 420 rear wheel power to the base (as supported by a 12 second or under quarter mile).
There is a strong possibility C63 weighs around 3600 lbs. 0 to 60 3.9s is an estimate and as the poster above me alluded to, it's likely a grip issue as the C63s has 255 wide rear tires versus the M3's 275.

Here you go. This particular configuration is a 6 speed manual M3 and it was put on a scale and it weighs 3600 lbs. Add another 30 - 40 lbs for the DCT weight and a DCT comparably equipped would have tipped the scale at 3630 - 3640 lbs.

Check the edit again. 3595 lbs for BMW M3 with 6 speed manual. 1/4 mile 12.3@114 mph.

Justin Bell and Townsend Bell go head-to-head once again during this episode of Shut Up and Drive, but this time they do it behind the wheel of the 467-hp RC F.
Both drivers take advantage of the long straights at Palm Beach International Raceway, and let the V8 stretch its legs.
See if Justin wins out or if Townsend has enough talent to bring the RC F across the finish line first.

While you might not like to admit it, it's not a low 12 second car "at best": While not an M3, the M4 (heavier than the base M3) got an instrumented objective tested 3.7s 0 to 60 and a 12.0s quarter mile with DCT:

You're going to call their test a freak test too? At the end of the day, it's C63s and M3 and then everything else miles behind.

The way I look at, can it hold up well against solid 12 seconds cars? It cannot. For example, a Porsche 911 Carrera S with PDK is a solid 12 - 12.1 seconds car and it is quicker than the M4. Same with Jaguar F Type R or Stingray Corvette.
If you want to believe the M4 is a 12 seconds car then you will have to bump the other cars that run 12 seconds, but are known to be faster than the M4 relatively speaking.
Most importantly, in a head-to-head drag race, the M4 was 5/10ths quick han RC-F in the same conditions and same track with the same driver.
RC-F is certainly not "a mile" behind. It was only 3/10th slower than M4 (equipped with optional carbon ceramic brakes) with Randy Pobst on the same track.
I think this video demonstrates what a "solid" 12 seconds performs like versus an M4.

Short answer - Absolutely not.

and then youre just gonna ignore how comparable both cars are in the real world?

In German car tests (AMS, AutoZeitung etc.) have done several direct head to head comparisons with Carrera S and it simply outclasses the M4 in every department and it is typically in the range of 12.1 - 12.3 seconds in those tests.
M4 is a low-to-mid 12 seconds range car. There is far more evidence of 12.2 - 12.4 seconds for the M4/M3 than there are 12.0 seconds. Simply no one can ever deny that, with objective and rational thinking.
At least the Jaguar F type garnered 5 stars like the M3/M4 from caranddriver - RCF? not so much. And not so much in nearly all other publications too.
And way to interject track speed tests to this discussion when we're discussing straight line speeds. Track times and conditions have more variability. If anything, having a driver drive 2 different cars back to back on the same track immediately after one another induces more variability as the driver's experience and intuition with the other car is fresh in mind.
(Maybe, it makes you feel better about your IS-F by putting down the RC-F? Perhaps?)

so wait...you used a video where a twin turbo 3 liter V6 just punches it from a dig...against a car with twice the displacement doing the same...as proof positive that the M4 isnt a 'solid 12 sec car'. why use that video to illustrate a point when no tests are done in that manner (ie...brake torquing/launch control)? did you expect anything different with a highly boosted car thats just idling vs a 6 liter v8? and we're just gonna ignore what happened when they went from a roll (which demonstrates, more accurately, how much power each car has)?
and then youre just gonna ignore how comparable both cars are in the real world?
i guess we're just lucky that both cars didnt just spin out with all that low end torque

That was one example. Even a Juice Box Stage 4 (not 1, 2 or 3) tuned M4 could barely inch out a bone stock 6 speed manual Stingray (slower than auto) from a rolling start (no launch variability). In another one, a Dinan tuned M4 got beaten by a stock Stingray 8AT. Way too many videos all showing the same pattern.
I only wanted to post stock vs stock to make it apples to apples, which is why I picked that video.
Both of my prime examples (Porsche 911 Carrera S and Stingray) are typically tested somewhere in the low 12s. All I am saying is, the M4 is far more a low-to-mid-12 seconds car than anything else. I believe no one can deny this statement.

Most importantly, 5/10ths at those trap speeds is equivalent to a bus length. It's not even close. You can split hairs all you want talking about whether the F8X is a "solid 12 second car" (What does that even mean?) at the end of the day, the RC-F is not in the same league in terms of acceleration. Fact.

It would not have ended any other way no matter what.

thats 3 mph faster than any stock vette has posted on DT...
this is JB4 on map 7 vs a FBO GTR making about 600/600. and you think it would barely inch on a stock vette?

OMG. This is getting just ridiculous at how the RC-F gets trashed. I know RC-F has it flaws, but by the same token I don't own the car, but I feel for the owners on this forum and the unfair flack and disrespect this gets by Lexus owners (no offense, but particularly IS-F owners and it is a very consistent pattern).
That is 5 car lengths at best according to my calculations in the 112 - 117 mph trap speed range.
p.s. A "solid 12 seconds" car means something that can consistently and repeatedly get that number. The M4 cannot. Plain and simple.
Look at this video and tell me at the finish line that 3/10ths at 115 mph trap speed is "bus lengths". It is 3 car lengths at best.

anywho...this looks like its about to take a turn so im gonna eject before i get lumped into the collateral damage. let the record show that my posts had NOTHING to do with the RCF vs anything. hahahahaa
