Default 0-60 Under 4 Seconds difficulty

How difficult would it be to get a new RCF to under 4 seconds 0-60?

i don't think hard at all. my previous ISF was hitting 4.1 easily with just an exhaust, light weight wheels/tires, . the newer year ISFs were getting those numbers almost stock.

I think that with the weight, auto and no launch control, it would be pretty hard. The cars on this list are either lighter weight, stick or have LC.

The RC-F does 0-60 in about ~4.5sec (I'm assuming that number is based on the best run)

There is no way you can save 5/10th of a second without having to loose a bunch of weight followed by better Exhaust, Air filter, Dyno Tune and other mods.

Maybe with a Super charger you will be able to do 0-60 in 4sec flat.

4.2 - 4.3 seconds is the norm for the RCF (Motortrend, C&D etc.) with minimal launch.

The 4.5 is from Lexus website, and I'm sure the 4.5 is probably the BEST (not average) number achieved in ideal conditions.

Well it says 4.4 seconds (4.5 seconds is GSF). You do realize that is the official claim, which are almost always pessimistic. You should check Caranddriver, MotorTrend, RoadAndTrack results. You will see it did 4.2 - 4.3 seconds.

BTW. RoadAndTrack got a freak run of 3.9 seconds 0-60 mph with the RCF. Not sure if this is repeatable

Not sure how accurate this chart is, but it looks to be pretty accurate. And I don't believe I've seen a time slip from an RCF with street tires below a 2.0 60ft....so unfortunately I'd have to say the RCF is a 4.8-5 sec car realistically, 0-60.
And of course magizines post the BEST times, not the Average. They may have tried 40 to 50 0-60 runs and just took the best one/time and marked it.
I have no doubt that it can get down to very close to 4.5 0-60 with just exhaust though.

0-60 mph is irrelevant when it comes to drag strip. Only 1/4 mile times matter there (or the 1/8th mile). Stock Lexus RCF in the hands of a race car driver did run a 12.5 seconds bone stock in cold conditions at sea level (Bahrain). I believe his 60' appeared on the screen as 1.96.

Wonder what tires they had on it?! Doubt the stock summer tires if it was "cold conditions" as the stock summer tires don't hook good enough for a 1.9 60ft in cold weather, lol. AMHIK

E.Kanoo said it was bone stock. It is actually 1.96 so it is closer to 2.0 than it is to 1.9.

Sorry to be the rainy cloud but I personally investigated that 0-60 time with the Road and Track web editor and the 3.9 sec time was a typo. The RC-F actually did a 4.3 sec 0-60 during the R&T PCOTY competition.

Weight reduction (lighter parts and wheels) along with supercharger w/ tune should easily net 3.5-3.7 0-60 times.

Wow, great investigation finds. Thank you for finding that. I was definitely on the fence when it comes to sub 4 seconds for our F cars due to the big whop of mass being carried and the lack of low end torque.

Claim debunked.
