TMG's super Lexus LS Sports 650 gets track tested

The people at Toyota Motorsport GmbH have been responsible for the Japanese automaker's motorsports efforts since the 1970s, but since Toyota pulled out of Formula One after the 2009 season, the tuning shop has been developing a super sedan based on the Lexus LS called the Sports 650. Details on TMG's first road car have been scarce, but XCAR was recently invited to drive the 641-horsepower Lexus on track.
Here's what we know: the Sports 650 has enough power to sprint to 60 miles per hour in under four seconds, tops out at 199 mph, weighs over two tons and utilizes LFA brakes. Oh, and its twin-turbo V8 bellows like an AMG V8. That last part isn't surprising when considering TMG could become Toyota's in-house tuning arm - like AMG is to Mercedes-Benz. As for the bespoke body kit, fender flares and stacked exhaust pipes? They fit the car well and even remind us a bit of Lexus' other high-performance sedan, the IS F. Currently there are no plans for the Sports 650 to be made into a production car, but we doubt TMG is devoting this much effort developing the LS into a road-rocket for nothing.
Check out XCAR's video below to see the AMG-fighter wrung out on track, and then ponder what could be if TMG were let loose to fiddle with other cars in Lexus' lineup. Now that's something we could get used to!

Toyota reveals cause of heartbreaking failure at Le Mans

Toyota was set to become only the second Japanese automaker to win the grueling 24 Hours of Le Mans endurance race. But on the last lap, the No. 5 TS 050 car, which was being driven by Kazuki Nakajima, suffered a technical issue that resulted in a sudden loss of power. In a team statement, Toyota Gazoo Racing has revealed that the culprit was a "defect on a connector on the air line between the turbocharger and the intercooler." The defective air line connector, according to the statement, resulted in a loss of control over the turbocharger. The team isn't sure why the connector failed and is continuing to analyze the component to get down to the root cause, the team said in the statement. During the race, the team was able to get the No. 5 car running again by modifying the control settings. The fix, however, came a little too late as the vehicle could not complete the lap under Le Mans' maximum final lap time of six minutes and limped its way to 45th place. While the team is working hard to find the fix – to avoid a similar type of failure in the future – it claims there is no relation to the engine issues that were experienced by the two TS 050 cars at Spa during the World Endurance Championship in May.

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.
