I sure hope this is NOT like the BMW M computerized sound generation through the speakers.
I just don't believe it. Can't be. Better not be!
Any type of sound re-creation is not cool for me but I could put up with channeling sound into the cabin. Not creating it artificially. That just won't do.

What I am thinking as well. We'll know very soon. Looks like the spec is about to be released...finally...based on the thread from the UK.

It's real boys & girls...
It's now "Official"
Active Sound Control
The sound blasting from the RC F’s quad stacked tailpipes is sure to turn heads and raise
pulse rates. Yet, Lexus also had to design the cabin to be quiet enough to enable enjoyment of the standard premium sound system or sonically stunning Mark Levinson® Premium Surround Sound system.
How could RC F drivers enjoy both? The answer is Active Sound Control (ASC), which lets the driver control enhanced exhaust, intake and mechanical sounds within the cabin. Specifically, Lexus sought to approximate the aural experience provided by the Lexus LFA, which issued some of the most stirring mechanical intake and exhaust notes of any supercar. Although LFA V10 engine revs to 9,000 rpm and RC F’s V8 to 7,200 rpm, the engineers have come close.
An electronic control unit mounted beneath the instrument panel takes input from engine sounds, including varying engine speed, vehicle speed and throttle position and generates augmented sound through an actuator. It is entirely separate from audio system, so there’s no reduction in music fidelity.
Most importantly is the driver controls ASC. It’s activated only in SPORT S+ mode, not Eco, Normal and SPORT S modes. And when it’s on, ASC blends with the natural intake and exhaust sounds to about a 50:50 ratio.
At engine speeds up to 3,000 rpm, ASC issues a steady tone of low and deep sounds. As revs rise, the tone transforms into a higher-pitched note that blends with the engine’s mechanical sounds, culminating in a free-soaring sound beyond 6,000 rpm.
Enjoy,

From what I can hear in track tests, the RCF makes plenty of noise.

That secondary air intake flap (as seen on the IS F) opens at 3,600 RPM
Either way.. More noise

IS 300h has this ASC system to and it´s probably the most stupid thing I ever heard in a car. It sounds like a video game from the 80ties. Thankfully you can turn the volume off completely in all driving modes, and I really hope that RC-F has the same opportunity.
On the other hand, where can I download this fake RC-F cabin sound to install in the IS 300h ?
