2019 Mazda CX-3 crossover updated with a tad more power and refinement

NEW YORK — Mazda's smallest vehicle, the CX-3 subcompact crossover, is getting a refresh for the 2019 model year. Visually, you'd be hard-pressed to tell what changed, and that's because not much did. The grille now has slats that are grouped in pairs, and the rear taillights have been redesigned. But there are a number of changes aside from visuals that separate this model from the 2018. Under the hood is still a 2.0-liter naturally aspirated four-cylinder engine. It picks up two more horsepower and pound-feet of torque for totals of 148 for each, though Mazda says that it also picks up torque across more of the rev band and gets better fuel economy. Mazda didn't have official mileage numbers, though. The CX-3 will also now come with the G-Vectoring Control system that helps improve turn-in by reducing torque and shifting weight forward. The steering and suspension have been slightly retuned, and the tires developed to better absorb bumps. Deeper inside the CX-3, several changes should make the driving experience more calm and refined. These include thicker door panels and rear door glass to make things quieter. The seats are now wider with redesigned foam cushions for greater comfort. A new integrated armrest in the center console and one in the rear seats with cup holders help the same cause. Mazda will also add faux suede trim to the cabins of CX-3s for a more premium feel. Pricing hasn't been announced for the new CX-3, but the little crossover will go on sale in late spring. So expect pricing to come soon. Fuel economy numbers will likely be available soon, too. Related Video:

Cedar Rocket is the fastest all-electric log car in the world

An electric turbine manufacturer, a mechanic, and a log house builder walk into a bar. No, wait. The three are standing around at Barrett-Jackson a few years ago, talking about the world. What's the eventual punchline? An all-electric vehicle mash-up of a Mazda RX-8 and a giant piece of wood. One that was just awarded a Guinness World Record for "fastest motorized log." "Truly, what else would you think of?" - Bryan Reid, Sr. Bryan Reid, Sr., star of the reality show Timber Kings, is the log house builder in the set-up above, and he's now the proud owner of Cedar Rocket. He told AutoblogGreen that a log-based EV is the natural result of the three guys chatting. "Truly, what else would you think of?" he said. "I mean, really? There has to be something to come out of it other than girls. It was crazy, but it's a good story and nobody gets hurt. It's hard to make the news when everything's positive." Idea in hand, Reid and his friend set off to actually build the car. Gerald Overton, the mechanic, turned the Mazda into a welcoming recipient, working on the disc brakes, axles, frame, differential, and suspension. While the presence of a television producer kept things moving, Reid said that it still took almost two years. "It started out, not as a joke, but as something very light," he said. "You put a log on a couple of axles and 'ha ha.' It ended up taking many thousands of hours. We don't do anything halfway." In the end, Reid and the team took the Cedar Rocket to the Wild Horse Pass Motorsports Park in Chandler, Arizona and managed two runs of 55 miles per hour within an hour (that's what Guinness required to hand out the official record). The Rocket is incredibly stable – heavy batteries help there – and Reid pointed out that because the EV uses electric turbines, it's not a quarter-mile car. "It's more like a salt-flat car," he said, because the "turbines that take a while to spin up." Given the right conditions, Reid said the team thinks the Cedar Rocket could go 120-130 mph. "It's crazy because it's different." But the point of this car isn't to just go fast. The builders will bring the car to Barrett-Jackson and auction it off next year, but before that it will make the rounds at places like SEMA and a number of unexpected events, like golf shows. The point is to get attention and raise money and awareness for veterans groups. "I believe it's for the best cause in North America," he said.

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.
