The long legendary discontinued engine, are being heard will make its second big entry
"Despite the engine's absence from the U.S. market since 2012, Mazda never quit working on the rotary, a technology it began using in the 1960s. - Detroit
And the company's North American president and CEO says the engine, also known as the Wankel after its inventor Felix Wankel, is primed or a return.
"Well,(the) rotary engine is our heart-line " - Masahiro Moro to the WardsAuto, sidelines of the 2018 Automotive News World Congress.
The message above completely quoted from here
So the Rotary engine itself are inherently small compared with portlier internal-combustion engines ( conventional engine) with the major downside of it know for its relatively poor fuel efficiency and emissions, leading to world market exit six years ago, well not to the chop shop and underground alike, they still rock em' hard haha.
I mean look at that, who doesn't want to get their hands dirty hand put an aftermarket part already lol, totally near impossible to find a stock rotary based Mazda, Continue on the matter
at CES Las Vegas Moro are asked to define near-term regarding this issue, he said it himself in a "few years" he expects the rotary will return as part of the propulsion system in joint-venture partner with Toyota's e-Palette, autonomous concept that is also revealed at CES
To put it, Mazda or promising an old matter issue such as fuel cumbustion and quality of the rotary which is offered in the last RX-8 (sports car) but then discontinued
More can be seen in here, regarding the promised major upgrade such as 'sans fuel-cell stack' owh man, its getting abstract at this point I say.
