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:

Recharge Wrap-up: BlaBlaCar raises $100M, NASA launches CO2 satellite

BlaBlaCar, a ridesharing startup in Europe, has raised $100 million in a funding round led by Index Ventures. After recently growing to 12 countries and 8 million users, BlaBlaCar plans to us the funding for even more aggressive growth throughout Europe. The ridesharing service pairs drivers and passengers, allowing passengers to catch rides between cities while allowing drivers to save money on fuel on road trips. Drivers are not allowed to make a profit, and are only allowed to charge enough to break even after BlaBlaCar takes its percentage, to keep costs low for everyone involved. BlaBlaCar doesn't currently have plans to break into the US. Read more at The New York Times or at Gigaom. NASA has launched its Orbiting Carbon Observatory-2 into space to keep track of carbon dioxide in Earth's atmosphere. After being delayed on Tuesday, the Delta II rocket equipped with an instrument to measure CO2 launched from Vandenberg Air Force Base in California at 5:56 am on Wednesday. It is ultimately headed for a polar orbit to watch how CO2 levels rise and fall throughout the seasons, in part to try to figure out if the land and oceans will continue to be able to absorb half of carbon emissions. The mission will last two years, and should give further insight into climate change. Learn more in the video below, at NASA or at New York Times. Mazda is likely to release a plug-in version of its Mazda2 hatchback with a rotary range extender, reports Australian site Motoring. The electrified Mazda2, and any other future Mazda EVs and hybrids, will likely be limited to markets with government subsidies for such vehicles (which doesn't include Australia) says Mazda Australia Managing Director Martin Benders. "As the best possible fuel economy at an affordable price hybrid doesn't make sense, because the fuel economy gain isn't that great unless half of all sales are hybrid, which won't happen without big tax breaks like in the Netherlands," said Benders. That doesn't rule out the US, though. A prototype version of the range-extended Mazda2 featured a 0.33-liter rotary engine to provide power to the lithium-ion battery pack when depleted. A 2.6-gallon gas tank essentially doubled the electric Mazda2's driving range to 250 miles. Read more at Motoring. Zap plans on selling 1,000 Urbee EVs per month to SunRa for distribution in China.

Electric Miata smokes Tesla Model S at the track

Yes, folks, you read that headline right. A souped up battery-electric version of a Mazda Miata took down a Tesla Model S on a quarter-mile drag strip. And it wasn't even close. Road Test TV was kind enough to post a video of a forest-green Miata (and its very stoked driver) doing a quarter-mile run in a rather brisk 9.27 seconds, beating the Model S sedan by a whopping 3.5 seconds in the process. And the Mazda crossed the finish line moving at 142 miles per hour, or 40 miles per hour faster than the Tesla was going when it finished the race. It's a good thing for the Tesla owner that they weren't racing for pink slips. Granted, the comparison is probably an unfair one because the Tesla was a stock, production vehicle (the P85 Performance model, but still), whereas who knows how the Miata was juiced up and how much cash it took to do the job. It's sort of like putting, say, an automotive writer against Usain Bolt because we ate the same breakfast and share 99 percent of our DNA. Still, the video does lend a certain credence to the idea that a battery-electric, super-light, rear-wheel-drive Miata would be a lot of fun, or at least a heck of lot more fun than any other Mazda out there. We're just sayin'. Check out the 100-second video below, and remember not to blink. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
