Driving the Maserati MC20 and BMW i7 | Autoblog Podcast #802

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor, Green, John Beltz Snyder and Road Test Editor Zac Palmer. They're amped up about the BMW i7 and Maserati MC 20 they've all been driving. They also opine about the BMW M3 CS and 2024 Ford Mustang. The Japan Mobility Show (formerly Tokyo Motor Show) is coming up, and there have been some interesting reveals and teasers, including the Nissan Hyper Urban and Hyper Adventure concepts, some neat kei car concepts from Daihatsu, a Miata-inspired EV concept from Mazda and an electric sports coupe concept from Subaru. Finally, they discuss the wild situation surround last weekend's Formula 1 Qatar Grand Prix. Send us your questions for the Mailbag and Spend My Money at: Podcast@Autoblog.com.

Mazda Recalling Cars Due To Spider Webs In Engines

It seems that Yellow Sac spiders really, really love Mazda. Three years after Mazda recalled 52,000 Mazda6 sedans over spider webs obstructing the evaporative canister vent lines of 2009 and 2010 Mazda6 models, another recall has been issued for 42,000 more of the models built between 2010 and 2012 and equipped with the 2.5-liter four-cylinder engine. According to the automaker, there have been nine confirmed sightings of spiders in vent lines since the original recall. It seems that covers were applied at the factory to keep the arachnids from entering, but it hasn't quite exterminated the problem. A reflash of the ECU is required that "[changes] the logic behind how the car purges the charcoal canister during normal operation," says Jeremy Barnes, Director, Public Relations & Brand Experience at Mazda North American Operations. So far, Mazda has not recorded any fires, accidents or injuries due to this tangled mess of webs. Recall notices will be mailed out to owners later this month.

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.
