This whole rotary v. piston debate I always thought was a little pointless with the rx8...honestly, it needs a turbo. However if you asked me it needs a V8. In fact, think of any car, then imagine it with a rwd v8 powertrain. Did that just make the car better? Yeah, it did. V8 Miata? Rwd V8 Mazda6? Hell, rwd V8 New Ford Taurus? I firmly believe Pontiac would still exist if all their cars were rwd and V8 based. Solstice? Shoulda had a V8. VW golf? Needs a V8. Prius? V8.
I defy you to think of any car on earth that wouldn't be better with a rwd V8. A smaller engine is more fuel efficient you say? The bible doesn't say anything about fuel efficiency, I say, we ignore the problem until global warfare breaks out, and deal with it then. Or, how about a RWD V8 twin turbo diesel? Still a V8.
