Bighearted enthusiast rescues stranger's Mazda RX-7 from floods

With Tropical Storm Cristobal charting a path for the Gulf Coast, a Biloxi, Mississippi, local named Khuong Nguyen wanted to get his FD-series Mazda RX-7 out of the storm — the coupe had some bad seals that would let in rain. He parked the orange and black coupe in the bottom story of a parking garage at the city's Golden Nugget Casino, which kept the rain from getting in. But Cristobal came on stronger than expected, creating a new threat of water from below when the parking garage began to flood. Austin Owens, a Gulfport resident about 10 miles from Biloxi, saw photos of the RX-7 with water up to its rockers on a local Cars and Coffee page. As he would later tell Jalopnik, the RX-7 being one of Owens' dream cars, he decided he needed to rescue it. Just to make sure we're all on the same page, a young man braved a tropical storm in his own vehicle to save a stranger's RX-7 in another city. Owens dragooned a friend and hopped in a Ford Bronco, dodging closed roads and fording three or four feet of water on open roads. They drove to Home Depot to pick up cinder blocks, then headed to the Golden Nugget parking garage. As Owens and his friend arrived, they met Nguyen and a couple of his friends pulling Nguyen's second car, a Ferrari 360, out of the garage on a trailer. The RX-7 had already been set on wood blocks, thin bricks, and some orange wheel chocks, but the stilt job wasn't high enough in front; the water in parts of the garage was knee deep. Owens jacked up the RX-7 to get the cinder blocks under the front wheels; the rear end was fine, due to the slope of the garage floor. Success. As one of Nguyen's friends told Jalopnik, Owens' actions "did give us adequate time to combat the rising water." The success came at a cost, though, Owens reporting, "We actually killed the [BroncoÂ’s] transmission on the way out. We actually had to drive in second gear all the way home" due to floodwater seeping into the transmission. He has no regrets, explaining his derring-do with, “ItÂ’s a rare car ... I would hope somebody would do the same for me if I was in the situation with a car of that stature. I didnÂ’t have it in my heart to leave it there." With the story blowing up on Facebook, he told the legion of enthusiasts sending their respects, "Appreciate the love, but IÂ’d expect the same for one of my cars," followed by, "Alright, whoÂ’s down for some Forza?" Save for the original seal issue, the RX-7 came out of the storm with no issues.

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.

Next Mazda CX-9 to launch by 2016, could get turbo-four

Mazda has a lot going on these days, what with launching the new Mazda6 and Mazda3, with the new Mazda2 just around the corner. We know the new Miata is also on the way, and after that it looks like the next vehicle in its lineup due for an overhaul is the CX-9 crossover, due to launch by 2016. The move makes sense because the CUV is growing long in the tooth. It was first introduced in 2007 and was refreshed twice since then.
The next-generation CX-9 will move away from Ford-derived components like the V6 in the current model and will likely use a turbocharged four-cylinder engine. However, a final decision hasn't been made yet. "If I ask Mr. Hitomi, our top guy of powertrains at Mazda, he believes the downsizing turbo solution costs more. But real downsizing means six-cylinder to four-cylinder turbo could make sense from a cost point of view," said Mazda's global marketing boss Masahiro Moro to CarAdvice at the New York Auto Show. The executive said a hybrid powertrain option would be unlikely, but markets outside the US could get a diesel, as well.
Moro also tipped his hand at future Mazda model plans. He hints that the Japanese automaker is considering building a luxury vehicle with a six-cylinder engine. "It's too early, we don't have a car yet. But we are collecting advice as to V6 or straight-six," he said to CarAdvice. We'll definitely be watching.
