Will the Mazda2 be offered as a PHEV with a rotary engine range extender?

Every few months, it seems a rumor crops up about plans from Mazda to revive the rotary engine. Last November, its CEO said the only way another one could happen is if the project was profitable, and then a month later the automaker showed off the Mazda2 RE Range Extender with a 330cc Wankel engine mounted in the rear. Now, Australian auto site Motoring reports that the PHEV may actually make production in the next-gen Mazda2 sometime after it's initial launch.
Martin Benders, managing director of Mazda in Australia, spoke to Motoring about the company's future with hybrids and basically reiterated what the CEO said last year. The Japanese automaker only plans to offer electrified powertrains in places where they can sell in sufficient numbers to be profitable, like Japan.
Mazda has been playing with the rotary range-extender idea for years. In the RE prototype, the engine was exclusively used to charge the lithium-ion batteries when they were running low, and a 100-horsepower electric motor provided all of the propulsion. It gave the little hatch an estimated range of about 250 miles. The company reportedly took inspiration from its Skyactiv engines to make the Wankel have lower friction and a lighter weight.

Weekly Recap: Toyota, Mazda team up to 'make cars better'

Toyota and Mazda are teaming for a noble purpose: to "make cars better." That's how the two Japanese automakers termed their partnership, which was announced this week. So what does this actually mean? The companies said they will set up a joint committee to look for areas of cooperation and named safety and the environment as issues they plan to tackle. From a product perspective, it's believed that Toyota is interested in Mazda's Skyactive engine portfolio. In turn, Mazda has its eye on Toyota's fuel-cell and plug-in hybrid technology. While more specifics were not confirmed, the companies said the "agreement will go beyond the traditional framework of cooperation," and it has the potential to be a long-range partnership. "The main purpose of this initiative is to enhance the appeal of our cars," Toyota president Akio Toyoda said at the announcement. Previously, Mazda has licensed Toyota's hybrid tech and assembled compact cars for Toyota in Mexico. Akio Toyoda said these projects "triggered" the automakers to explore further collaboration. Dave Sullivan, product analysis manager for AutoPacific, said the tie-up echoes Daimler's wide-ranging work with the Renault-Nissan alliance. "This could be a well-groomed match due to each having very unique skill sets," he said. OTHER NEWS & NOTES Volvo selects South Carolina for US factory Volvo confirmed this week that it will build its first US factory in South Carolina, with construction set to begin this fall. The company first revealed plans in March, though it didn't announce a site. The plant will have initial annual production of 100,000 units, though the vehicle or vehicles to be assembled were not specified. The factory, located near Charleston, will open in 2018 and ultimately employ 4,000 people. The facility will help Volvo continue its growth strategy, which includes strengthening its presence in the US market, where it wants to sell more than 100,000 cars per year. "Building a plant in the US is a reflection of Volvo Cars' commitment to the US and the key role the US plays in our growth objectives," Lex Kerssemakers, senior vice president, Americas, said in a statement. Ford GT spied on the road The 2017 Ford GT was spotted testing around the Blue Oval's headquarters in Dearborn, MI, this week. The raw body panels were exposed, and they lacked paint or camouflage. It's the first time the GT has been captured on the street after a spring of auto show reveals.

Tougher than steel: Wood pulp could make lighter auto parts

KYOTO, Japan — The global push among carmakers to make ever lighter vehicles is leading some auto suppliers in Japan to turn to what seems like an unlikely steel substitute — wood pulp. Japanese researchers and auto component makers say a material made from wood pulp weighs just one-fifth of steel and can be five times stronger. The material - cellulose nanofibers — could become a viable alternative to steel in the decades ahead, they say, although it faces competition from carbon-based materials, and remains a long way from being commercially viable.> Related: Jay Leno drives the Renew cannabis car — hemp you can't dent Reducing the weight of a vehicle will be critical as manufacturers move to bring electric cars into the mainstream. Batteries are an expensive but vital component, so a reduction in car weight will mean fewer batteries will be needed to power the vehicle, saving on costs. "Lightweighting is a constant issue for us," said Masanori Matsushiro, a project manager overseeing body design at Toyota. "But we also have to resolve the issue of high manufacturing costs before we see an increased use of new, lighter-weight materials in mass-volume cars."A NEW PROCESS Researchers at Kyoto University and major parts suppliers such as Denso Corp, Toyota's biggest supplier, and DaikyoNishikawa Corp, are working with plastics incorporated with cellulose nanofibers — made by breaking down wood pulp fibers into several hundredths of a micron (one thousandth of a millimeter). Cellulose nanofibers have been used in a variety of products ranging from ink to transparent displays, but their potential use in cars has been enabled by the "Kyoto Process," under which chemically treated wood fibers are kneaded into plastics while simultaneously being broken down into nanofibers, slashing the cost of production to roughly one-fifth that of other processes. "This is the lowest-cost, highest-performance application for cellulose nanofibers, and that's why we're focusing on its use in auto and aircraft parts," Kyoto University Professor Hiroaki Yano, who is leading the research, told Reuters in an interview. The university, along with auto parts suppliers, are currently developing a prototype car using cellulose nanofiber-based parts to be completed in 2020.
