The redesigned 2019 Mazda3 moves way upscale

Mazda didn't lie — the 2019 Mazda3 is a gently reworked production version of the Kai concept shown at last year's Tokyo Auto Show. In hatchback and sedan forms, you'll still quickly peg this a Mazda3. The dimensions barely change: The wheelbase grows by an inch, but the hatchback width and length carry over, while height decreases by an inch; the sedan is the same width but 3.2 inches longer and 0.7 inches lower. Nevertheless, the look and details have evolved throughout, yielding a much more potent and piercing hatchback, and a more sophisticated, accomplished sedan. Instead of using hard shoulder and swage lines to "draw" contour onto a flat profile, Mazda designed a car with contours that create real shoulders and hips. Shedding the illusion of surface depth for reality redefines the look and presence of the Mazda3. The new model erases the hash of lines and embossed panels in back of the current car so that the S-curved hatch has only its shutline for framing. After that, the highlights enhance the theme. On either side of the larger grille, single-lens headlamps get new accents; instead of a just plain silver bar, streaks of amber turn signals decorate the more dimensional units. The contoured taillamp housing holds highly structured, highly embellished twin circles that probably look even more sinister at night. On the sedan, those naughty taillights are surrounded by a refined rear valance with a more angled, muscular lip along the trailing edge. It's the same inside, a design based on results of Mazda's in-depth studies of human mechanics. The flatter instrument panel stresses clean lines along the horizontal. Trimmer steering wheel spokes with silver buttons line up with the central span across the dash housing the climate control buttons and vents. The new shift panel sits higher and more forward, making it easier for the driver to move a hand from the steering wheel to the lever. To raise perceived luxury, the center tunnel trim is a clear layer laid over a laser-engraved black layer, said to produce a "look of deep transparency," and similar to the effect found on the new BMW X5 and X7. The cupholders are now in front of the shifters, and the armrest is longer. There's no mention of that digital gauge cluster that leaked earlier this year, though. Buyers who opt for fabric will get a new "Greige" hue, a mix of gray and beige. Mazda designed a new leather grain with creases of varying depths and shapes depending on where it's placed.

Mazda won't build new Mazdaspeed3 or 6 based on current models

It's sad news but not entirely unexpected: According to a Motoring interview, Mazda doesn't intend to build high-performance versions of the latest Mazda3 and Mazda6. Instead, it will wait for the next generations of those cars to arrive before applying the Mazdaspeed treatment. When the future performance models do eventually arrive, expect them to take a step upmarket compared to the last ones. In the meantime, the Japanese brand will focus its engineering resources on the next-generation Skyactiv engine family, according to Mazda's North American operations president and CEO Masahiro Moro. "Our research and development department is 100 percent focused on delivering Skyactiv generation two and if we don't have this we don't have any other derivatives," Moro told Motoring. Once the new engines arrive around 2017, Mazda's engineers can start to develop performance versions. "MPS or performance model or a sort of iconic model of the future will be a little bit later at this stage," Moro said. Moro is already thinking about the direction for the future performance vehicles. He calls the previous Mazdaspeed3 "childish" and thinks it's time to go a different way. "Mazda brand has become more mature, more upscale, more sophisticated, and we have a new transition of the brand to relate that direction," he said. Rumors last year suggested that Mazda might introduce a new Mazdaspeed3 (speculative rendering above) as a concept at the 2015 Frankfurt Motor Show. It would have reportedly used the CX-9's 2.5-liter turbocharged four-cylinder tuned to 295 horsepower and an all-wheel-drive powertrain. The vehicle never appeared, though. The current Mazda3 and Mazda6 arrived in 2014, so a new generation of each wouldn't arrive until around 2020. That would put Mazdaspeed derivatives at 2021 or later. In short, it will be a while. For customers that have the Driving Matters attitude now, Mazda still offers the award-winning MX-5 Miata as a convertible and soon with an impressive folding hardtop. Plus, Fiat will sell its own versions of the car with 160 hp. We wouldn't mind if Mazda turned up the heat a little by introducing something like the Racing concept from last year's Tokyo Auto Salon, though. Related Video:

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.
