It worked. Really cool stuff too. It is great to see that Mazda is going back to its roots. I really liked the Mx-5 and I can't wait to see that. But a 4-door Rx-7? I don't know about that one. I guess we can only wait

Meanwhile, chief Mazda rotary engineer Hiroshi Kinoshita indicated a larger capacity version of the 184kW RX-8's 1.3-litre twin-rotor Renesis engine with side-mounted exhaust and induction ports was the preferred option to power the next RX-7 - or a higher-performance RX-8 variant - rather than increasing the number of rotors or turbocharging.
"There are three possible ways to increase power from this engine," Mr Kinoshita said. "Turbo is one, using extra rotors is another and using wider rotors to increase engine capacity is a third.
"This engine can be turbocharged, that is technically possible, but there is still more power available through normal aspiration.
"For me, the most suitable method would be the third - increase capacity with bigger rotors."
No turbos

"Yes, a new RX-7 is heavily under development right now," Mr Katabuchi told GoAuto at the global RX-8 launch at Laguna Seca in California last week.
"Of course, it is not yet approved but a new RX-7 is definitely being developed.
--Sweet!
"In the past we put rotary engines into all our passenger cars but now we realise that was a mistake," said Mr Katabuchi.
"Rotary has a unique character that's more suitable for sports cars and I believe the most appropriate use for rotary technology is in sports cars."
--Oh so true!
