Mazda will build a successor to the famed RX-7 and RX-8 complete with a rotary engine, according to Auto Express. The new rotary-powered sports car, expected in 2017, will be based on an extended and reinforced variant of the upcoming fourth-generation Mazda MX-5 Miata ’s chassis, the report says.

While Mazda is the only manufacturer to actively pursue Felix Wankel’s rotary design, the automaker has its work cut out to find solutions to the engine’s inherent flaws of high fuel and oil consumption and low torque output. The new engine is said to be being developed with the automaker’s Skyactiv approach to efficiency used on its piston engines such as natural aspiration, weight reduction, and high compression ratios.

The report suggests the new naturally aspirated rotary engine could produce as much as 300 hp – a substantial jump over the RX-8 ’s 238 hp. While Auto Express suggested the a six-speed manual or five-speed automatic would back the new rotary engine, we expect the new sports coupe to use the Miata’s six-speed auto. For optimal performance, it was also suggested the new sports car would be a lighter two-seater like the RX-7 rather than a heavier four-door RX-8 type vehicle.
