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 details diesel prototype at Daytona test

Diesel has without a doubt become the dominant fuel in the modern era of endurance racing. The 24 Hours of Le Mans has been won under diesel power for the past eight years running, as has every race in the FIA World Endurance Championship since its inauguration in 2012. Yet there will only be one diesel prototype entered in the top tier of the new Tudor United SportsCar Championship this year, and it belongs to Mazda.
The last Japanese manufacturer to win at Le Mans outright, Mazda has been gradually working its way back up the endurance racing ladder once again, following the example set by Audi with diesel power. Last year it campaigned a competition-spec Mazda6 Skyactiv-D in the GX class of the Grand-Am series, but rather than simply port over the existing racer into the new series, it's fielding a new prototype instead, just as it promised a couple of months ago. And now that prototype has hit the track for the first time, prompting Mazda to release its basic specs for the first time.
Tentatively referred to simply as the 2014 Mazda Prototype, the purpose-built racecar is testing this weekend in the Roar Before the 24, the official test session at Daytona that kicks off the racing season. It packs a 2.2-liter SkyActiv-D engine that's based heavily on the production version but tuned to produce 450 horsepower and 580 pound-feet of torque in race trim. Power is channeled through a six-speed sequential transmission from Xtrac, carbon brakes from AP and 18-inch racing slicks from Continental. With the Daytona-spec aero setup, it'll top out at around 186 miles per hour.

Mazda MX-5 breeds upgraded Roadster RS in Japan

Fans of the new Mazda MX-5 Miata looking for something a little more performance-focused may be enticed by the new RS model. Unfortunately they'll have to go all the way to Japan to get it. Because Mazda will only be offering this particular version back home. The new RS version of the Mazda Roadster (as it's known in Japan) features a number of performance upgrades, although none of them specifically affect the engine or its output. The Roadster RS features Bilstein dampers and front suspension tower brace for better handling, along with bigger brakes for added stopping power, a retuned steering rack for sharper turn-in, and upgraded exhaust for a better sound. Inside it's also been treated to heated Recaro seats with Nappa leather and Alcantara trim and a nine-speaker Bose audio system. It also comes equipped with adaptive front lighting and high-beam control as well as lane-departure and blind-spot warning systems. Feeling left out yet? Don't be too disappointed, or book that ticket to Tokyo's Natita International Airport just yet. The Mazda Roadster RS only comes with the smaller 1.5-liter engine that produces 129 horsepower, which is significantly less than the 2.0L we get here at 155 hp. It does, however, come with the six-speed manual instead of the automatic. So while this may not be the most powerful version of the Miata, it may be the enthusiast favorite – at least in the JDM.
