Mazda to revive RX-7 in… 2017?

There is a special place in our hearts reserved for the Mazda RX-7. Its screaming rotary engine made the ’80s and ’90s a time of high-revving fun. While Mazda continued the rotary with the four-door RX-8, the two are not the same car, and eventually the latter was phased out.

The Motor Report is the latest outlet to crank up the rumormill over a return to Wankel power and an RX sports car for the troubled Japanese brand. According to TMR, a rotary engine could come back – and so could the RX-7 nameplate – albeit not overnight. The return of the RX-7 is said to be set for 2017, and the source quoted is none other than Mazda sports car boss Nobuhiro Yamamoto.

Speaking with the press at a local launch of the updated MX-5 Miata, Yamamoto said the future RX-7 would have a curb weight close to that of the Toyota GT 86 (about 2,600 pounds), and have a larger emphasis on the driver’s involvement. Yamamoto was also the powertrain chief for the JDM-market FD3S generation (1992-2002 model) and was extremely proud of that engine. Yamamoto reportedly says he would prefer a naturally aspirated version of that engine over any kind of forced induction solution, claiming that the 16X rotary engine that has been developed would be capable of 220kW (295 hp) in that configuration. The 16X was developed in 2007 but has yet to find its way into a production vehicle.

2017 would mark the 50th anniversary of the introduction of the rotary engine. Frankly, it would be a shame if some form of the quirky and revvy powerplant was not found under the hood of a sports car anywhere in the market.

Mazda rumored to use laser-ignition for next-gen rotary

Autocar is reporting that the next-generation rotary engine from Mazda may turn to a laser ignition system instead of traditional spark plugs. The report supposedly comes straight from the mouth of a shadowy senior engineer within the program. Mazda has been hard at work on the 16X Renesis rotary since around 2007 and the engine has seen quite a few evolutions over the intervening years. Autocar says that the design has seen displacement swell from 1.3 liters to 1.6 liters and that at least some parts of the engine have been designed to be made from aluminum to further reduce weight.

The work is in an effort to get the rotary to be more fuel efficient and provide more torque, the latter not usually being a chief attribute of this type of engine. According to Autocar, using a high-temperature laser ignition system would allow engineers to tune the Wankel to run leaner than systems that use a conventional spark plug. It would also reportedly allow the engine control module to more accurately adjust and monitor timing.
