Wow, so they're releasing the RC-F ahead of the regular RC versions? That's a first.![Smilie](https://www.clublexus.com/forums/images/smilies/smile.gif)
Anyhow, is there confirmation that the engine in the RC-F is still the 2UR-GSE? Or is it an all-new engine?
If it is using the 2UR engine, then I would like to know how we jumped from 416 HP (in the ISF) to 460 HP (in this new RCF)...........given that this engine is naturally-aspirated (aka no force induction).

It was way downtuned in the ISF
A picture is a thousand words, just look at it!

why would you keep it in atkinson cycle at full throttle?

but i am sure eco will not be atkinson at full throttle... it is a sports sedan with almost 500hp... at full throttle you get full power.

i think it'd be cool to make eco mode more useful by keeping it in atkinson cycle. so even if you're accelerating from a stop, or whatever, it stays in atkinson cycle and thus better mpg.

Anybody who buys an RC-F and is worried about such a thing is buying way too much car. There are smaller engine variants for people who want the best possible fuel economy. If you want the best fuel economy in any car...don't accelerate at full throttle!

I can't believe we're talking about this in a small run, low volume high performance v8 coupe lol especially with the same person who wrote the car off because it's 300 pounds more than an M4

secondly, this mpg saving tech is probably the only reason this car still has a V8. in city driving who wouldnt want better mpg? this tech doesnt take away from the 460-480 hp when you want to burn dead dinos....

and yes, you go crazy about 300lbs extra and then you want to accelerate with 120-150hp less because you want to save fuel.
it is funny :-)
