Test drive done, please help me out by giving your feedback.

I have no proof. Just read from a lot of people who own 3IS, RC etc or Lexus in general, that the car completely changes character after a few thousand miles.
Here is one thread where the owner was "disappointed" in the 3IS initially for lacking power. The Lexus LFA had a reduced rev limiter for the first few hundred miles at 7500 rpm. After which, it went up to the full 9500 rpm, but Lexus never put such a mechanism in any other car.

It's all there. Just give it time to lap up some miles and learn your driving patterns.

Has anyone else experience this with their RC-F off the lot, and did you notice an improvement over the next hundred miles?
It almost feels like something is restraining the power, a bottleneck.
BTW the highest octane in my country is 93, perhaps the ECU is is still calibrating?

The new RC F that I test drove with 5 miles on it in sport+ mode accelerated with gusto--no glaring restraint in power delivery.

M4 = 405 lb/ft @ 1850rpm. ~3550lbs. RCF = 389 lb/ft @ 4800rpm. ~3950lbs
BMW grossly underrates their power figures too, not sure about Lexus. Nonetheless, simple math is the explanation to why the RCF doesn't "feel" fast.

What it feels and does are at variance: the carbon is 2-3 tenths off of the M4; the RC -F has three times demonstrated superiority on the track, and it has a higher top end speed of 170 versus the M4's 155. The M4 appears to be significantly flawed on the track as a result of unmanageable boost and excessive oversteer.

Update:
I went to the dealer again and asked to drive the RC-F once more. This time I immediately switched to Sport+ and traction off, and it was showing "Expert mode"
0-100kph time was 4.5s with a passenger, so everything is good. I did a couple WOT 2nd and 3rd gear pulls, WOW, what a difference compared to Sport and traction ON. The lack of power I was describing earlier was completely gone!
However, while the RC-F doesn't feel fast, it is actually deceptively fast, in my first launch I remember going through 2 gears and when I looked up I was already going 120kph, the second time I paid more attention to the speed and let the beeping guide the shift and took the time with my phone.
Everything about this car is superb, the noise, the handling, the interior!!! I can't wait until the end of the month for the deliver, it's a White/Red TVD. So excited
Novel, GReddy, RS-R and Vossen are the brands in my list of potential mods, so stay tuned for the build thread!

Just remember that peek power on this is at redline so you have to shift at redline to get the most out of it, sounds like you did that this time.
I had the same issues with my old M5 and NSX when people drove it and shifted 1/2 way up the redline
It's not a American V8 where peek power is 1/2 way to the redline lol.

When we did a drag race for kicks, I completely destroyed him after 2nd gear. I was shocked and did not expect that considering how much quicker his car "felt".
