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!

Lexus LS sedan will be quieter, more comfortable and smarter

Lexus made numerous updates to the LS in a bid to turn it into an even more comfortable cruiser. Unveiled online, the redesigned model gains a quieter cabin, new driving aids, and a handful of minor styling tweaks. Engineers turned their attention to parts of the fifth-generation LS that a majority of owners never think about in order to achieve a ride that's markedly quieter and smoother. They notably fitted a new solenoid to the adaptive suspension that reduces damping force, redesigned the motor mounts to prevent mechanical vibrations from entering the cabin, and changed the stiffness of the run-flat tires as well as the rigidity of the stabilizer bars. These changes come together to cement the sedan's positioning as the cushiest model in its category. Deeper stitch points and seat pads made with low-resilience urethane further enhance comfort, according to Lexus, but the biggest upgrades found inside are technology-related. The LS receives a digital rear-view mirror as well as a 12.3-inch touchscreen compatible with Android Auto and Apple CarPlay. Users can also control the display screen and audio functions using their phone once they've paired it to the infotainment system. LS buyers in select markets will be able to order the company's Teammate technology. It's a semi-automated suite of driving aids that bundles lane-keeping assist and adaptive cruise control while allowing the car to change lanes and pass slower vehicles. It does not turn the LS into an autonomous car; it merely helps motorists when driving becomes tedious. The system can only be used when the right conditions are met, and Lexus hasn't announced plans to offer it in the United States. The latest generation of park assist technology is available, too. The visual changes are relatively subtle. Up front, stylists redesigned the lights and gave the bumper a new look. Out back, eagle-eyed car spotters will notice the lights and the lower bumper have been slightly revised. It's the same story inside, where the most noteworthy change is the addition of the aforementioned touchscreen. Lexus expanded the color palette with a shade of silver named Gin-ei Luster that stands out with a smooth, mirror-like finish.

Apple uses Logitech steering wheels and pedals to control autonomous cars

SAN FRANCISCO (Reuters) - Apple outlined a plan to train operators of self-driving cars in documents submitted to California regulators earlier this month, the latest clues to the company's autonomous vehicle technology aspirations. Apple was granted a permit to test self-driving cars on April 14 by the California Department of Motor Vehicles but the company has never said anything about its plan. The state released 41 pages of Apple application documents to Reuters that give some clues about the company's highly secret self-driving effort, which it has never openly acknowledged. The iPhone maker joins a long list of carmakers, start-ups and technology rivals, including Alphabet's Waymo, that are testing cars on state roads. Apple is looking for new hit products and autonomous car technology is expected to revolutionize the traditional auto industry. As part of the application, Apple included a 10-page training plan that appeared to be related to operators taking back manual control of the car during automated driving exercises of the system, which it calls a development platform. Business Insider reports that Apple engineers riding in the back seats have the ability to take over control of the car using off-the-shelf steering wheel and pedal video game controllers from Logitech. Apple declined comment beyond the filing. The plan includes a document called "Automated System: Development Platform Specific Training Overview" whose objective is "to train safety drivers in various automated driving conditions." "Development platform will be controlled electronically (e.g. joystick) and safety drivers must be ready to intervene and take control," the document reads. The document highlights different scenarios to be tested, from high speed driving and tight U-turns to lane changes. One letter sent from Apple to the state Department of Motor Vehicles noted that Apple's development platform "will have the ability to capture and store relevant data before a collision occurs." The document does not include detail on how Apple's self-driving platform actually works or other technical details. It also does not say what kind of sensors are found on Apple's three permitted vehicles, all 2015 Lexus model RX450h. The permit does not necessarily mean that Apple itself is building a full car. Apple could instead be designing a self-driving platform that can be integrated into other manufacturer's cars. (By Alexandria Sage.
