Toyota announces GT86 CS-R3 rally car

Toyota Motorsport GmbH has developed cars for all manner of racing, up to and including Formula One and Le Mans. But it got its start back in 1979 in rally competition, winning four drivers' and three manufacturers' titles in the World Rally Championship. And now it's announced a new rally car.
Based on the Toyota GT86 (better known to us as the Scion FR-S), the CS-R3 rally car isn't built to contest the top tier of the WRC, but is being developed to conform to the lower R3 class. That means a six-speed sequential gearbox, limited slip differential and upgraded engine, brakes, aero... the works. It'll retain the road-going model's rear-drive setup, joining the front-drive Yaris R1A in TMG's portfolio of customer rally cars.
Further details are set to be revealed "in the coming months", but the GT86 CS-R3 will benefit from the experience TMG accrued in developing the GT86 CS-V3 (pictured above) for the Nürburgring-based VLN endurance racing series.

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.

How Toyota's 100-year textile history influenced FCV hydrogen fuel cell car

Turns out, Toyota had a surprising ace in the hole when it came to building the new fuel tanks for the FCV hydrogen fuel cell car, which is coming next year. Well before Toyota became the Toyota Motor Company, it was the Toyota Industries Corporation and it made textile looms. This is important because the main structure of the hydrogen tank is wound carbon fiber. When Toyota set out to increase the strength of the tanks to hold hydrogen stored at 10,000 psi (up from 5,000 in the previous tanks), it was able to draw on its 100-year-old history as it designed its car of the future. "A lot of that textile experience came back when we did the tank wrapping." – Justin Ward "We have a lot of experience with textiles," Justin Ward told AutoblogGreen at the 21st World Congress on Intelligent Transport Systems (ITS) in Detroit this week, "and a lot of that textile experience came back when we did the tank wrapping." On top of being able to hold the higher-pressure hydrogen, Toyota's first attempt to build its own hydrogen tank was six times faster than the industry standard, so it saved time and money as well as working better. The company will also be able to inspect its own tanks. Ward is the general manager of powertrain system control at the Toyota Technical Center and hydrogen vehicles are something he knows a lot about. The reason for the stronger, 10,000-psi tanks is because the 5,000-psi tanks only offered around 180-200 miles of range, even with four tanks in the early $129,000 FCHV Highlander hydrogen prototypes. The FCV only has two, but they will able to deliver the 300-mile range that customers told Toyota they wanted. Dropping the number of tanks not only obviously reduced the cost for the tanks themselves but also the number of valves and hoses and other components you need. Despite the benefits of higher compression, going much higher doesn't make sense. 10,000 psi is the "natural progression," Ward said, because "you start to bump up against compression inefficiencies." Think of an air compressor. When hydrogen is produced at a wastewater treatment plant or a reforming site, Ward said, is it at around ambient pressure (14 psi). That has to be raised, using compressors, all the way to 10,000 psi. "That takes energy," Ward said, "and every doubling of pressure adds another doubling of energy needed, so it starts to add up pretty fast if you go too high." Component specifications are also fine at 10,00 psi, but more difficult at higher levels.
