They put millions and millions into developing a new high tech rotary engine at mazda for their miata sports car. The result was an extremely durable, extremely clean running engine. It produces a LOT of power appearantly. Its a "three cylinder" version. Also, with the stick shift model it has a redline of 12,000 RPM.

and the automatic has a 9,500 rpm redline to protect the torque converter. Yikes. I read a review on one around a year ago, and the guy said it absolutely rocked and highly recommended the manual model, nothing like shifting at 11,000 rpm! The engines also deliver almost a steady torque output across much of the rpm range, its awesome.
However, I'll stick with my 617.
