Mazda engineer wants new rotary to be turbocharged

Hope springs eternal for Mazda to revive the high-revving Wankel engine for a new sports car, and the company keeps feeding that thirst with hints that it could happen. To make the possibility even more tantalizing, Mazda drivetrain and powertrain assistant manager Tetsushi Marutani tells Motoring that he wants the updated mill to pack a turbocharger. "Personally, I think that a rotary with some turbo or compressor would be good," Marutani said to Motoring. "Because a rotary, in my opinion, they require more [torque at] low speed, low down torque. So if we have some small compressor or turbo it would help." Mazda hasn't sold a rotary-powered model since the RX-8 and hasn't had a turbocharged one since the third-generation RX-7. However, the recent RX-Vision concept (above) at least hinted at a possible Wankel revival, and Mazda officials confirmed that its engineers continued to develop the engine since the RX-8's demise. The RX-Vision used a next-gen rotary called the Skyactiv-R, but Mazda didn't officially confirm any details about it. Rumors suggested the engine had a two-rotor layout with a total displacement of 1.6 liters. A two-stage electric turbo and hybrid powertrain would allegedly boost the total output of around 450 horsepower. The electric assistance could also counter the Wankel's lack of torque at low revs and poor fuel economy. Those rumored specs sound fantastic, but we still take the rotary's return with a grain of salt. Mazda CEO Masamichi Kogai is adamant that it's not worth the company's limited resources to develop a niche sports coupe instead of better selling vehicles. Related Video:

Mazda revamping dealers with 'Retail Evolution'

Mazda introduced its Retail Revolution dealership design language 12 years ago, which focused on open-plan spaces, multimedia areas, and allowing customers to interact with the brand before needing to interact with a salesperson. Two years ago the carmaker started work on the next step in its dealership design, and the new language, called Retail Evolution, was unveiled at Mazda of Everett in Seattle, Washington. Aiming to make the Mazda brand feel more premium and increase dealer profits, it goes even further on the open-plan to create "a new level of business transparency." It's all done with a lot of black, white, raw wood, metal finishes, and a lot of glass. Mazda Lounges will offer free wi-fi, and digital displays will replace static photographs. So as not to hurt showrooms still recouping their investment in Retail Revolution, Mazda will work with dealers to figure out how best to update facilities, and the Retail Evolution has three tiers that can be adapted to particular locations. The press release is below, a couple of renderings are above. MAZDA ANNOUNCES ALL-NEW RETAIL EVOLUTION DEALERSHIP DESIGN Mazda of Everett Showcases First Ground-Up Retail Evolution Design IRVINE, Calif. (August 27, 2015) – Mazda North American Operations (MNAO) today announced its all-new dealership design, dubbed "Retail Evolution", featuring an open concept floorplan that offers a new level of business transparency, and a look and feel enhanced through the use of natural materials that results in an even more upscale decor than the company's current popular Retail Revolution design. The first Retail Evolution dealership built from the ground up to this exacting standard will be Mazda of Everett in Seattle, Wash., opening today. "Thanks to our KODO design philosophy and suite of SKYACTIV technologies, our vehicle lineup has never been stronger. We are now able to take that groundbreaking design language and translate it into our dealership experience," said Jim O'Sullivan, president & CEO, MNAO. "Retail Evolution embodies the spirit and direction of the Mazda brand, while offering an upscale experience our customers expect and deserve." Clad in premium black, clean white, and featuring new chrome Mazda signage, the new Retail Evolution Mazda dealerships will provide dealers with strong curb appeal. New materials throughout the building give dealers an upscale look and feel with warm raw-material tones of wood and metal in the showroom.

Recharge Wrap-up: Renault-Nissan hits 250,000 EVs, will the next Toyota Prius be an SUV?

Will the next Toyota Prius be an SUV? Mazda and Toyota recently reached an agreement to share powertrain technologies, which will help Mazda comply with California's tightening ZEV restrictions with a plug-in vehicle. On the flip side, Toyota will have access Mazda's Skyactiv diesel powertrain, which a source tells Motoring will be used in an SUV based on the Toyota Prius (and, as Hybrid Cars suggests, on the Toyota C-HR concept). Interestingly, the collaboration will also give Mazda access to Toyota's fuel cell technology, which could mean more hydrogen powered cars on the road and the subsequent expansion of hydrogen fueling infrastructure. Could it also make way for a long-awaited hydrogen powered rotary-engine sports car from Mazda? Read more at Motoring. Samsung SDI unveiled two new lithium-ion stationary batteries at Intersolar Europe.

The quarter-millionth EV was a white Renault Zoe sold to a French computer engineer from Bordeaux named Yves Nivelle. While he credits a government program offering a ˆ10,000 rebate for EV buyers trading in an older diesel vehicle for helping him make the decision to pull the trigger on the new Zoe, "I have to say, I was convinced the first time I drove the car. It's a real pleasure to drive and it feels good to do my part for the environment," says Nivelle. The Alliance had sold around 31,600 EVs from January to May this year, up 15 percent from the first five months of 2014. See the video above, and read more in the press release below.
