i'm betting that some of the new lightweight components are made from this...

stronger than aluminum and better heat transfer properties as well

The 13b in my 1978 RX-4 was pulling all of 110 hp, but it did get ~25 mpg. Mazda made a big mistake in not going to a catalytic converter right away and stuck with a big air pump and EGR. The Renny is a fabulous engine by comparison, but in pulling 230 hp, it's really pushing limits of what one can expect from a street engine where longevity and reliability are important. I'd much rather see the 16x pull 250 hp and get a solid 28 mpg, than get 300 hp with the mileage and other issues we see now.

The new Mustang is the first vehicle to have 300 hp and get 30 mpg. The LS engines from Chevy have more power than that and are knocking at the 30 mpg door too. These are highway miles of course and in cars that are heavier than the RX-8. If the rotary could hit 30 mpg highway, and I know it can, it would be quite nice. A light nible car would be welcome too. If Mazda gives us a reliable rotary (crosses fingers) in a car that runs in the 13's in the quarter, and returns 30 mpg hwy, it'll sell quite well. It's possible. They just need to do it.

Is it getting 30mpg while using the 400hp?
People always compare low power cruise mileage with high power burn, without anything between the two that is comparable really.
One reason I could easily see a potential 'enthusiast's' hybrid, where the last 'overdrive' gear isn't connected to the driveshaft, but rather a separate output shaft to an electrical generator to power a small electric motor on the rear diff or driveshaft, etc...
You don't need 400, 300, 200, or even 100hp to maintain highway speeds, and since it would only be operating when you are in the highest gear (6th in our case), all of your acceleration is gears 1 through 5, normal full enthusiast petroleum powered accerlation.
Having to get the electric motor and the powerplant to that motor capable of accelerating a car respectably is what makes the 'hybrid' idea so terrible for enthusiasts.
But any enthusiast that boasts, or complains, about X power and Y mileage, is comparing full burn to cruise. My solution would address each individually.

"I wanna go fast!"
Give me 20-25mpg combined, with 280hp NA model... and the top model with FI putting out 350. All on a 2 door 2 seater, 2800lbs. 50/50 weight with Rx8 handling.
You will see me drive one within 1 year of it coming out (unless its hideous). 3 things that brought me to my 8 was the handling, looks, and the rotary engine. Power was not a major thing... but IT BETTER HAVE MORE POWER!!!!!
MOOOOOAAARRRR POWER!!!!! More power is ALWAYS welcome for us men.
232hp... 180whp...blah.
I want 280 with at least 240whp... or the 350 with at least 300whp. Have the engine prepped for 15psi factory... and have the "Mazda" option to chip it and get MOOOAAAARRRR POWER!!! So that it wont void our warranty.
BMW and Audi does it... why can't mazda.
Man can dream.

300 WHP & 300 WTQ in a 2500-2700 turbo rotary car w/powerband, reliability, & handling like the RX-8 and I am sooooooooo there.
P.S. In mixed freeway/city driving, which includes plenty of WOT fun, I get around 25-26 mpg.

A car that powerful, and nimble would be an instant classic. I'm sure the suspension will see tons of updates, and at that weight, I can't imagine a stock car that good. I don't want to get my hopes up, but it was produced, I'd be right there with you.
