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 hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.

Mazda CEO predicts record US sales in next 2 years

The recently appointed CEO of Mazda is apparently quite the optimist, claiming that the Japanese brand, renowned for its Zoom-Zoom driving character (and more recently its sleek, refined designs and Skyactiv efficiency), is claiming the company will record its best-ever US sales within the next two years. According to a report from Automotive News, Masamichi Kogai expects Mazda to move 400,000 of its Kodo-styled vehicles in the increasingly competitive US market by March 2016, with the recently launched Mazda3 leading the charge. "It will impacted considerably by the trend of the U.S. industry. But... it's my hope we achieve the record by that time," Kogai tells AN.
The brand is currently targeting 300,000 units by the end of this fiscal year in March 2014. Given that production and sales of the Mazda3 (and consumer awareness of the 2014 Mazda6) is still picking up steam, it isn't a stretch to imagine Mazda, which sold 240,000 vehicles from January to October of 2013, hitting its target.
Along with the overall increase in sales numbers, Kogai is expecting the independent brand to take an even larger slice of the US sales pie, claiming 2.5 percent US market share, improving from its current 1.9-percent foothold so far in 2013. "I think the upper limit may be 2.5 percent for the time being," Kogai told AN, before pointing out, "We don't want to use a lot of incentives. That is not the sales approach we aspire toward."
