Mazda6 Skyactiv-D Racecar ready to bring diesel to Grand-Am

It may not be quite as radical as some of the company's past rotary racers, but the new Mazda6 Skyactiv-D racecar does have a notable powertrain underhood: the automaker's brand-new clean diesel four-cylinder engine.
Three of these new diesel-powered Mazda6 racers will take to the track in the Grand-Am GX class of the upcoming 2013 Rolex 24 at Daytona on January 26, with five drivers on each team. The car you see above, number 70, is sponsored by Mazda's longtime motorsports partner, SpeedSource.

Mazda patents show rotary engine for range-extended EV

Two years ago, Mazda introduced a fascinating range-extended electric car called the Mazda2 RE Range-Extender. It took an electric Mazda2, and dropped in an itty-bitty 330cc rotary engine. It wasn't the rotary-powered sports car we had hoped for, but it seemed like a unique way to keep the quirky engine alive and kicking. But not long after the car's reveal, it seemed to disappear. Now the basic idea has resurfaced with a few modern updates in a couple of US patents. The first patent is pretty straightforward and describes a range-extended EV similar to the BMW i3. At the front is an electric motor driving the front wheels. At the back is an internal combustion engine that powers an electric generator. In the middle is a lithium-ion battery for storing and delivering electricity. It's the same set-up as that Mazda2. The second patent is for an engine start-and-stop system, but specifically for rotary engines. The system is designed to shut off a rotary engine when not needed, much as modern piston engines do. It also stops the rotor in a position that closes the intake port to ensure no fuel or exhaust emissions slip out through the intake tract. This is necessary since there are no valves in a rotary, and air and exhaust come through ports that are "opened" and "closed" by the rotor itself. The patent also describes the possibility of firing a spark plug after the fuel has been cut to eliminate any leftover fuel emissions. This system would theoretically improve a rotary engine's fuel economy and emissions significantly, which would be a boon as those are two of the rotary's major weaknesses. The rotary-engine patent also includes the same range-extended powertrain drawing as the first patent. It's there as a description of a possible application. And in such an application, where the rotary wouldn't have to run all the time, the system could take advantage of the rotary's inherent strengths. Weight can be kept low thanks to the engine's small dimensions, which should help in keeping the car sprightly and efficient. Rotaries are renowned for smoothness, too, so it shouldn't need too much refining and sound deadening, the latter of which adds more weight. The small size would also help with packaging, leaving more space for people, cargo, or possibly batteries. And since it has been patented, the company may be looking to bring the system to market.

Mazda Koeru concept forecasts next CX-9 in sleek form

Mazda rolled in to the Frankfurt Motor Show this year with the Koeru concept you see here. The showpiece is the latest embodiment of the Japanese brand's Kodo design language, applied with dramatic effect to a large crossover shape. Could this preview the next CX-9? The Koeru takes its name from the Japanese verb for "going beyond," and the reason is plain to see: though created by a mass-market brand, the concept could easily belong to an upscale marque like Infiniti (which offers a range of crossovers), Jaguar (which just revealed its first), or Maserati (which is preparing to get in on the action as well). It strikes us as aggressive as it is elegant, with taut lines and sporty details from the sharp lights to the muscular wheel arches. Few technical details as to what lies underneath it all were made available. And these show cars often lack working underpinnings to speak of anyway. But Mazda says that, beyond the styling, it optimized the aerodynamics over the upper body as well as underneath it to reduce turbulence and "enhance vehicle stability when driving at speed." It's also said to encompass the company's latest Skyactiv, i-Activesense, and Mazda Connect technologies. Which is all well and fine, but we're looking forward to seeing what innovations the company might incorporate if and when the Koeru (hopefully) transitions from concept to reality. In the meantime you can scope it out in the live and stock image galleries above and below. MAZDA KOERU The all-new crossover concept proposed by Mazda Mazda Motor Corporation is unveiling the all-new crossover concept Mazda KOERU for the world premiere at the Frankfurt Motor Show this year. The Mazda KOERU demonstrates Mazda's unique and daring interpretation of a crossover vehicle, proposed for the fast-growing crossover market. Featuring the full suite of Mazda's new-generation SKYACTIV technologies and designed under the KODO—Soul of Motion design language, the concept offers sporty yet delightfully refined styling and driving performance. The name "KOERU", which literally means "exceed" or "go beyond" in Japanese, comes from Mazda's aspiration to deliver value that goes well beyond the existing category norms and standards. As the latest incarnation of Mazda's new-generation products, the Mazda KOERU crossover concept offers styling that exudes power, vitality and a new level of polished refinement.
