Mazda's Tokyo concept foretells of rotary revival

Mazda has long been rumored to be planning a revival of its rotary-powered sports car. Some of those rumors may have come down to wishful thinking as much as concrete information. But now, on the eve of the Tokyo Motor Show, new details have come to light. The Japanese automaker is slated to unveil a two-door sports car concept, previewed in the teaser image above. Little in the way of firm information has been made available prior to the show car's debut, but sources are now citing senior company officials as confirming it has a rotary engine. "It is a two-door, two-seater, Mazda CEO Masamichi Kogai told Autocar. "It is a pure sports car design. We have MX-5 and another icon is a rotary sports car. We haven't talked about market reach but this would be in that segment." R&D chief Kiyoshi Fujiwara added: "People think rotary can not meet modern eco demands. The SkyActiv engineers worked on rotary and gave it cutting-edge tech. It is an essential part of our DNA and it [will] just be passed onto future engineers. It is synonymous with the brand. Some time in the future it will return and be called SkyActiv-R." The last time Mazda produced a rotary-powered model, of course, was with the RX-8, which ended production in 2012. That was preceded by three generations of RX-7, the first of which will be celebrating its 40th anniversary in 2018. If it manages to get the Wankel technology up to modern standards, that could provide just the right opportunity for Mazda to launch a new model. Reached for comment, Mazda spokesman Jacob Brown told Autoblog: "While we can confirm that Mazda continues to develop rotary engines, we cannot confirm production of a rotary at this point. Rotaries are one of the signature engineering technologies that define Mazda, and we will continue exploring them to see where they may fit for production applications." Related Video:

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.

WAVE 2015: Metron 7 sets new record of 513 miles on one charge

Sometimes you just gotta push harder, faster, longer. Last fall, the Metron Institute team from Slovenia took their converted all-electric Mazda5 minivan on an impressive 457-mile journey from Bled (in Sloveniva) to Dubrovnik (in Croatia) without stopping to recharge at an average speed of 40 miles an hour. Today, as part of the WAVE Trophy 2015, the Metron 7 EV just finished up a drive of 826.1 kilometers (513.3 miles) on a single charge. The drive started in Berlin and ended in Karlsruhe, Germany. As you might suspect, a drive of this length on normal roads required a big battery pack. The total pack capacity was 108 kWh, thanks to the combination of the built-in 86-kWh pack that uses lithium polymer cells from Kokam and a 130-pound, 22-kWh external pack that Metron has developed that can charge the built-in pack while driving. The average speed of the 500-mile journey was 45 miles per hour (72 kilometers per hour) through rural countryside, towns, and some time on the highway. The drivers –Andrej and Jasna Pecjak – did not use air conditioning, but the fans were running. The weather was temperate enough that AC wasn't needed anyway these last two days. The Metron 7 was a part of the last two WAVE events and has been updated since the last record was set in October 2014. On the new record journey, the minivan was loaded up with gear, but the Metron engineers made improvements to the car in the last eight months: the side mirrors are smaller and they fitted a better aerodynamic cover underneath the vehicle, for example. Andrej said that the cost for the batteries was around $50,000, since some of the cells he got were used. Today's record is unofficial, but AutoblogGreen witnessed both the sealing of the charge port in Berlin and was in the car for the last 125 kilometers today.
