The RX-8 may be a much different car than the RX-7 that it replaced, but there’s one thing that’s exactly the same: the pure, simple fun of the excellent rotary engine. Smooth and turbine-like, there’s really no replicating its unique power delivery characteristics—approaching redline, it seems to want to keep on revving forever. That’s not surprising, considering that this very limited edition model comes with some refinements courtesy of in-house tuner Mazdaspeed, and the most important is the car’s new carbon fiber flywheel that allows the already rev-happy engine to spin up even faster. Other mild engine refinements boost output to 250 horsepower, and the Mazdaspeed version wears special bodywork to differentiate it from lesser versions. For rotary fanatics, this may be the ultimate RX-8.
