New autonomous testing ground in Michigan will help battle bad weather

If one of the big weaknesses of autonomous vehicles is their ability to navigate in the snow, consider this a trial by fire. The American Center for Mobility says it has opened its $110 million driverless car testing facility on the site of a former General Motors assembly plant in Michigan, with Toyota and auto supplier Visteon the first to begin testing this week. The ACM proving ground is a 500-acre site at historic Willow Run in Ypsilanti Township, near Ann Arbor. It's one of 10 sites designated by the U.S. Department of Transportation as pilot proving ground sites to test AV technologies. It features a variety of simulated environments to test driverless cars, including a 2.5-mile highway loop, two double overpasses, intersections, roundabouts and a 700-foot curved tunnel. It also opens just as the region experiences a series of snowstorms and the first frigid temperatures of the season. That ability to test autonomous vehicles in a wide variety of weather conditions is important, as autonomous vehicle sensors have struggled to handle cold, wet and snowy conditions. Google parent Alphabet in October said its Waymo division was expanding its winter testing operations to Michigan, making it the sixth state where it's testing its driverless car systems. In a Medium blog post, Waymo CEO John Krafcik wrote that "This type of testing will give us the opportunity to assess the way our sensors perform in wet, cold conditions. And it will also build on the advanced driving skills we've developed over the last eight years by teaching our cars how to handle things like skidding on icy, unplowed roads." Waymo also opened a development center in suburban Detroit in 2016, working with Fiat Chrysler to integrate its autonomous technology into Chrysler Pacifica hybrid minivans. Visteon began testing and validating its DriveCore autonomous driving platform to evaluate algorithms, vehicle-to-vehicle and vehicle-to-infrastructure technology and other systems. Toyota used the facility Wednesday to begin orientation and driver training. ACM has so far secured $110 million to construct the first two phases from founders Ford, Hyundai America Technical Center, Toyota and Visteon, and says it expects to announce more investment soon.

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.

Hi-po Toyota GT86 to get KERS?

We happen to like the Toyota GT86 - and, it of course goes without saying that the same applies to the Subaru BRZ and Scion FR-S, as well - just the way it is. Yes, that includes the standard 2.0-liter four-cylinder boxer engine and its 200 horsepower at 7,000 rpm.
That said, a little extra power never hurt anybody, right?
The most obvious way to add some punch to the GT86 would be with a turbocharger, and that has indeed long been rumored for an STI version of the BRZ. Will Toyota follow suit? According to Top Gear, the answer is no. Says GT86 chief engineer Tetsuya Tada, "I think 300bhp with a turbo and 200g/km of CO2 would be tasteless in this day and age. And a turbo would mean the loss of the GT86's uniqueness." Perhaps a bit harsh, but there you go.
