RUMOR: RX-7 to get Larger 2 Rotor Rotary? 
Speed Magazine
Posted: Dec 02, 2002
Dave Morris writes in about an article in "SPEED MAGAZINE": "There's a new RX-7 on the way. Senior Mazda engineers revealed key details during animated after dinner conversation at the October long range preview of the RX-8 in Hiroshima. The blueprint for the car is complete and the new two seater will share major systems with the RX-8. But while the new RX-7 will utilise the same elegant double A-arms front and five link rear suspension as the RX-8, as well as it electrically assisted rack and pinion steering, it will have a more powerful rotary engine. Instead of turbocharging the RX-8's 184kw Renesis rotary, Mazda is developing its largest ever two rotor mill, the power target is atleast 206kw.
"Mazda has always increased rotor width (similar to increasing cylinder bor and stroke in a conventional piston engine) in 10mm steps. The 10A engine had 60mm wide rotors, the 12A went to 70mm and the 13B twin and 20B triple rotor were 80mm, so it's a pretty safe bet the new rotors will go to 90mm."
Could the next RX-7 contain an engine dubbed the 14C? We'll have to wait. Rumors going around now say Mazda will not "produce" an RX-7 until/unless the RX-8 is a financial success. ("Produce" is the key word)
