Mazda Hazumi concept presages next Mazda2

Looks like Mazda's big Geneva Motor Show debut is actually something quite small. Teased here, the Hazumi concept "points the way to the future" for the brand's subcompact offering, the Mazda2. Details are slim as of this writing, but from what we can see in the image above, the Hazumi will use the same Kodo design language found on the Mazda3, Mazda6 and CX-5. We're big fans of this styling direction, so we fully expect the concept to be quite an attractive little number.
Hazumi means "bound" or "spring up" in Japanese, with Mazda saying this nomenclature is "particularly well-suited to a small car that appears to be bursting with energy." In other words, say goodbye to the friendly faced Mazda2 we've enjoyed since it launched in the United States in 2010. Instead, prepare for something decidedly more assertive, hopefully improving upon the already-great driving dynamics of the current subcompact. If we're honest, we can't wait.
Mazda will also use the Geneva show to debut its new small-displacement, 1.5-liter Skyactiv-D diesel engine. The automaker hasn't confirmed that this new fuel-efficient powerplant will be part of the Hazumi concept package, but considering the two are debuting alongside each other, it would seem to make sense. As for whether or not this engine could come stateside when the next Mazda2 launches, we're not holding our breath for that, especially considering the company's current woes with US-spec diesel engines.

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.

World Car of the Year finalists announced

To say the 2014 Geneva Motor Show was packed full of news is an understatement as big as the show's home at the Palexpo convention center. Despite everything that we were able to cover during this year's show, there's still more coming out of Switzerland, including the announcement of the finalists for the 2014 World Car of the Year Awards.
We reported on the original list of finalists over three weeks ago, and now, that initial list has been pared down to three finalists for each of the five awards. The finalists were announced at a press conference by frequent Autoblog contributor and co-chair of the awards, Matt Davis (above).
The finalists for the overall title of 2014 World Car of the Year are the Audi A3, the BMW 4 Series and the Mazda3. The World Luxury Car of the Year will be either the Bentley Flying Spur, the Mercedes-Benz S-Class or the Land Rover Range Rover Sport, while the Performance Car of the Year will be awarded to the Chevrolet Corvette Stingray, the Ferrari 458 Speciale or the Porsche 911 GT3 (which, um, yeah...).
