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.

Mazda CX-5 diesels get discounts up to $10,000 off MSRP

When Mazda positioned its long-awaited and oft-delayed CX-5 diesel crossover as the “premium” option in the CX-5 trim structure, we were skeptical. After driving one last fall with a $42,045 sticker price, our eyebrows furrowed even deeper. Today, to nobodyÂ’s surprise, Mazda dealers are slapping massive discounts on the Skyactiv-D. CarsDirect initially reported on the discounts, pointing out that some dealers are slashing prices by $10,000. We took a spin through Autotrader to see what was out there, and the results were shocking. There were pages of CX-5 diesels with prices in the low-to-mid $30,000 range. We asked Mazda what kind of incentives it was currently offering on the 2019 CX-5 diesel. Since December, Mazda has offered a $5,000 cash rebate, alongside a 2.9 percent APR for 60 months. However, the other several thousand dollars worth of discounts weÂ’re seeing listed — as much as $5,000 more — are not being accounted for by Mazda.  Just as CarsDirect found, the largest discounts we could find on the web are for a cool $10,000, bringing the price down to $32,045. At that price, youÂ’re looking at a 23.8 percent discount. ThatÂ’s a discount of nearly a quarter(!) of the carÂ’s original asking price. We thought the Skyactiv-D was overpriced originally, but at this price, weÂ’d strongly consider it as the CX-5 to buy. Since the diesel is only offered in the top-of-the-line Signature trim, it has every gizmo and gadget Mazda offers in addition to the most premium interior materials. ItÂ’s also offered in all-wheel drive only, leaving every box with a checkmark in it.  Compared to the gas-engined CX-5 Signature that starts at $38,100 for the 2020 model year, these diesels are a steal. In fact, this price hierarchy makes a lot more sense than the way Mazda had it organized in the first place. The more powerful 2.5-liter turbocharged four-cylinder in the gas-engined Signature can easily be marketed as the most “premium” option in the CX-5 lineup since itÂ’s the fastest and most enjoyable to drive. Moving the slower diesel with the same equipment below it on the food chain sounds like the right move to us. At around $33,000-$35,000, the diesel isnÂ’t such a bad buy anymore. Fuel economy still isnÂ’t where weÂ’d like it to be, but as we opined in our First Drive review, itÂ’s still a wonderfully pleasant car to drive. Related Video:    

This is the 2017 Mazda MX-5 RF targa-roof fastback

We knew Mazda was going to introduce a new Miata variant ahead of the 2016 New York International Auto Show, but the smart money was on a power retractable hardtop version that largely mirrored the last-gen car's folding number. So it was a surprise when the new 2017 Mazda MX-5 RF – retractable fastback – drove onto the stage sporting wild buttresses and a hide-away targa roof panel. The buttresses lift up and swallow the rear window and roof panel in a matter of seconds, and then the buttresses snug back down. This leaves a hoop spanning the buttresses, but at least it's done up in black to be less visually apparent. The result is more of a targa roof experience, rather than the previous PRHT which gave occupants essentially the same experience as the soft-top with the top down. No matter. The result is stunning, and will differentiate the RF even more from the standard MX-5. Mazda designers took extra care to make sure the interface between the MX-5's dramatic fenders and the trailing edges of the roof support provided enough visual drama. Mission accomplished, we'd say. We can't take our eyes off that part of the car. View 13 Photos As you might expect, mechanical changes seem to be minor, although we'll be asking for detailed specs. Both the 1.5- and 2.0-liter engines will be available globally, but only the 2.0-liter Skyactiv-G engine will be sold in the US. The roof can be operated at up to 6.2 mph. Mazda claims the truck space is unaltered from the soft-top model. We don't yet know how much, if any, the RF's mechanism adds to the bantamweight roadster, nor the premium it'll command. Expect those details closer to launch. Related Video:
