Mazda2 with extended-range hybrid rotary tech shown

Every story dealing with a new rotary engine from Mazda lands in a different place on the matrix of possibilities between "Coming soon!" and "Never gonna happen!" In 2011 it was speculated that the rotary engineering program would be shut down with the demise of the RX-8, in 2012 the program was still alive and taking lessons from the SkyActiv engines, in August 2013 a Mazda insider said a rotary engine called 16X would be here in two years, in November the CEO said the only way we'd ever get a new rotary is if Mazda could sell 100,000 of them per year. Meaning that, for the moment, you can forget about it.
And yet, last month Mazda was putting journalists in a Mazda2 RE Range Extender, an electric car using a 0.33-liter rotary to power its lithium-ion batteries when the charge runs down. With a 75-kilowatt, 100-horsepower electric motor turning the front wheels, the Wankel generator and its 2.6-gallon gas tank living under the trunk double the range of the electric-only Mazda2 to 250 miles.
There's been talk of using a rotary to assist an alt-fuel vehicle for at least seven years, with Mazda pairing an electric motor with a rotary that ran on gas and hydrogen in a Mazda5 in 2007. Since then, almost all of those stories debating its return or demise also spoke of the oddball motor's advantages, such as compact size and ability to run on various fuels, as an aid in an unconventional powertrain.

Mazda Skyactiv-D racer first diesel to run at Indy in 60 years

While it may not be touting the old "Win on Sunday, sell on Monday" axiom we all know and love, Mazda recognizes that racing can only improve its cars. And so it's no surprise that the Japanese automaker is testing and refining its Skyactiv-D diesel engine by sending it out on various race tracks around the country - notably being the first diesel ever to compete at Daytona and the first to notch a Grand Am win at Road Atlanta.
Next up? Indy. It has been over 60 years since a diesel-powered machine ran at the Indianapolis Motor Speedway, and the Cummins-powered racer that competed in the 1952 Indy 500 with a 6.6-liter inline-six-cylinder oil-burner was a fast and brutal machine that set a new lap record in qualifying leading up to the race. Though that car was withdrawn with turbocharger failure 71 laps in, its diesel powerplant left an indelible impression on the racing community, and that's something Mazda hopes to accomplish once again.
Mazda says that the diesel engine in its race car is pretty darn close to stock - 51 percent stock by parts count, and 63 percent stock by weight - which means the way it performs in competition is at least a somewhat meaningful way to the stock engine's durability in the real world. Check out the image of the Mazda6 Skyactiv-D racer posing alongside the 1952 Cummins above (click to enlarge) and feel free to peruse the press release below for the rest of the details.

Combine "sports car" with "user-friendly" and, in most forums, you have yourself an oxymoron. Sports cars are – by definition – sporty, but rarely do they qualify as easy to use. One that did and, regrettably, has faded from the scene is Mazda's RX-8. Initially launched in 2003, and out of production within roughly a decade, the RX-8 was perhaps the rotary-powered answer to a question few – at the time – were asking. Happily, Mazda produced it anyway. With its front mid-engined platform, freestyle doors and +2 seating, the RX-8 came as close to offering day-in, day-out utility as anything this side of an extended-cab pickup. And its nod to practicality did little, if anything, to diminish the essential goodness of the menu. Mazda's design team provided a high-revving rotary, nimble handling and almost telepathic steering, combining them into a frenzy-filled dollop of locomotion. The result was no more than mildly fast and furious, but in properly motivated hands the RX-8 delivered a high level of entertainment for a relatively modest outlay. This for-sale example, a 2004 RX-8 with automatic transmission, requires just $6,000 and – not incidentally – the ability to buy into its premise. The automatic will be perceived by many to be a negative, but might also suggest a more gentle ownership history. And without benefit of a clutch and shifter, the new owner can concentrate on the driving, with the Mazda's absurdly direct steering and slot-car cornering. The asking price is on the high side (book average is about $5K), but know that similar cars might bring upwards of $8,000. And at 91,000 miles it's been used, but perhaps not used up.
