2017 Tokyo Motor Show | Mega Gallery

The 2017 Tokyo Motor Show has been a big and busy one. It's also had machinery ranging from beautiful to bizarre. But there's been something for everyone. Companies such as Honda and Subaru brought performance oriented vehicles, Toyota showcased a wide array of funky and practical concepts, and Yamaha even broke away from motorcycles to do another car concept. You can check all of these vehicles out, and more in the galleries below. 2018 Honda Gold Wing: View 5 Photos Honda Neo Sports Cafe Concept: View 5 Photos Honda Riding Assist-e Concept: View 7 Photos Honda Sports EV Concept: View 5 Photos Honda Super Cub: View 3 Photos Isuzu FD-SI and Elf EV: View 9 Photos Lexus LS+ Concept: View 18 Photos Mazda Kai Concept: View 18 Photos Mazda Vision Coupe Concept: View 15 Photos Mitsubishi e-Evolution Concept: View 8 Photos Nissan IMx Concept: View 29 Photos Nissan Leaf Nismo Concept: View 8 Photos Subaru Viziv Performance Concept: View 12 Photos Toyota Century and Crown: View 7 Photos Toyota Concept-i Series: View 16 Photos Toyota GR HV SPORTS Concept: View 6 Photos Toyota Tj Cruiser: View 12 Photos Yamaha Concepts (Cross Hub, MOTOROiD, MWC-4, Motobot): View 5 Photos Related Video: Tokyo Motor Show Honda Isuzu Lexus Mazda Mitsubishi Nissan Subaru Toyota

Mazda 16X rotary engine two years away, will arrive in all-new model

We last reported on Mazda's next-generation rotary engine project in June of 2012 when the automaker built its last Renesis-powered RX-8, but rumors of this new engine's development had been around way before that final car left the production line in Japan, last year.
We now have enthusiastic confirmation that this next-gen rotary engine is really and truly going forward. It is still referred to as 16X and has several priorities. First is to lower fuel consumption compared to the RX-8's engine, while still making gains in terms of performance. The second is to reduce the burning of oil that was happening at the highest revs. And the third and final priority, and perhaps most key for enthusiasts, is to give the powertrain a big torque upgrade.
What we were told by a Mazda USA insider (while we are all here together at the festivities in Monterey) is that the first application of the new 16X engine will be happening in two years' time in an as yet undisclosed new model. Oh, the mind races to our eternal Mazda wish list...

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.
