Mazda CX-3 almost ready for LA Show

The Mazda CX-3 is just days away from its unveiling at the 2014 Los Angeles Auto Show, but elsewhere in the world, the Japanese brand still has the compact crossover disguised for testing. These spy shots aren't too camouflaged though, and when combined with the previous teaser image, they give a pretty clear idea what the new model will look like.
The grille here is well covered, but the photo from the front reveals the similarities to the design sketch. The rear shows a similar horizontally oriented design as the Mazda2, which the CUV is based on. However, the dipping sides around the B-pillar from the teaser don't appear to be on this tester. Even with all the swirls, the vehicle looks fairly attractive.
Mazda is doing a fantastic job of keeping mechanical details about the CX-3 a secret. It's not yet known whether the model is front-wheel-drive only or if all-wheel drive is also an option. The crossover also likely shares the Mazda2's engine, which isn't revealed for North America, yet. The diminutive CUV will compete with a huge crop of new classmates, including the Fiat 500X, Jeep Renegade, Chevrolet Trax and Honda HR-V. Check out the gallery for the latest glimpses of this Japanese CUV just days ahead of its full debut.

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 Miata 25th anniversary display is roadster heaven on Earth

As part of the celebration of the 25th anniversary of the MX-5 Miata, Mazda has put together a rather large display at its New York Auto Show booth, showing off significant models from the diminutive roadsters history.
The display represents a healthy split of volume models, with cars 14, 15 and 17 sitting alongside cars 500,000 and 700,000. There are also more than a few concept cars in the offering, such as the Super20 Concept we drove a few years back, as well as older offerings, like the Club Racer concept from the 1989 Chicago Auto Show, the M-Speedster from the 1995 Chicago show and the M Coupe from the 1996 New York Auto Show.
We've put together a gallery of images of the historical Miata display, which you can view above. Take a look and then let us know which of Mazda's awesome roadsters is your favorite.
