Rotaries may seem like a thing of the past these days, especially with Mazda preparing to retire the RX-8. But the Wankel-powered sports car won’t be the last Mazda to get the odd powerplant, thanks in part to a recent breakthrough.
A recently big step forward for Mazda’s engineers is a newly developed laser ignition system that can remove spark plugs from the equation. This has made sealing the Wankel’s combustion chamber easier, resulting in better efficiency and, more importantly, lower hydrocarbon emissions.
This breakthrough could prove to be the catalyst Mazda needs to rejuvenate the RX-7 model, but it all comes down to finding the proper funding.
That influx of cash could come from a partnership with Audi. The two automakers are reportedly in talks and Audi’s A1 e-tron concept did use a 254cc Wankel range-extender underneath the trunk floor. The light weight, smooth and quiet rotary technology could prove the perfect pairing for a future production hybrid drivetrain for Audi.
