Toyota Mirai, Lexus LS show off Advanced Drive assists with OTA updates, AI

TOKYO — Toyota Motor Corp unveiled on Thursday new models of Lexus and Mirai in Japan, equipped with advanced driver assistance, as competition heats up to develop more self-driving and connected cars. Toyota's latest launch comes as automakers, electric car startups and tech giants invest heavily in so-called active safety features. The Japanese carmaker's new driving assist technology, or Advanced Drive, features a level 2 autonomous system that helps driving, such as limiting the car in its lane, maintaining the distance from other vehicles and changing lanes under the driver's supervision on expressways or other motor-vehicle-only roads. The system can even handle lane merges, and when passing trucks its lane system will move the car further to the opposite side of its lane. The car will recommend a course of action to a driver before executing it. The system also features a camera to monitor the driver's actions and level of attentiveness, and if the driver seems unresponsive or incapacitated, the car will pull itself over. The luxury sedan Lexus LS will be on sale from Thursday, costing between about 16.3 million yen ($148,600) and 17.9 million yen ($164,000), while the second-generation Mirai hydrogen fuel cell car will be offered on April 12 at between 8.4 million ($76,900) and 8.6 million yen ($78,750).

The new models are Toyota's first products brought to the market that provide over-the-air updates and utilize AI technology centered on deep learning, said Toyota executive James Kuffner, who is also the head of Toyota's research unit Woven Planet. "This is really an important first step in our journey towards software-first development," he said at an online briefing on Thursday, adding that the company has tried to design the software to be truly global and to provide re-usability. In the future, software features on cars will be "upgradable" and "more customizable" much like how people personalize their smartphones, Kuffner added. Fully self-driven cars are still likely to be years away, but rival General Motors early this year made a splash at the virtual Consumer Electronics Show with a fully-autonomous all-electric flying Cadillac concept, while Chinese search engine operator Baidu unveiled a partnership with local car brand Geely.

Lexus planning a hydrogen fuel-cell LS by 2017

Toyota's Fuel Cell System will certainly migrate to other vehicles in the carmaker's lineup, but Australian car site Motoring reports that one of the models at the head of the queue is the Lexus LS. According to its sources, the executive barge powered by hydrogen will be released by 2017 and take the top spot in the range, rolling in above the LS Hybrid. We're told that Toyota engineers will find a way to slide two hydrogen tanks into its bodywork with the same general setup as on the Mirai – one under the rear seats and another under the rear parcel shelf. The 150-kW fuel cell stack will be placed under the front seats. Motoring says the resulting sedan and its 220-kW electric motor would come in "at around 2,100 kg," which is 4,620 pounds; that's a ginormous 539 pounds less than the listed curb weight of the current LS Hybrid, and 387 pounds more than the standard LS. Assuming all goes as planned, it would have a range of roughly 238 miles, a few dozens less than the Mirai's range of about 300 miles. It would look slightly different, too, the front end getting larger intakes to cool the power unit. It wouldn't surprise us if Lexus does have a hydrogen LS planned – it would be a statement car, and the company likes making statements, even if few heed them; it has stuck with its LS 600h for the past seven years, yet of the 7,539 LS models sold through the end of November this year, only 61 of them were hybrids. The timing would be intriguing, however; by the time the LS hybrid came out, Lexus had already worked over its filet-and-potatoes models. And if the hydrogen version is going to come in above the $120,440 hybrid, well, that will be a statement indeed.

2021 Lexus IS debuts with new styling and greater emphasis on handling

The reveals keep on coming today. Lexus just took the wraps off the 2021 Lexus IS sport sedan, the fourth generation of its small, sporty four-door. It may not look all that different on the outside, but Lexus is making heady claims that the driving experience is going to be the real head turner. We’ll start with the looks, though. Lexus has only revealed the 2021 IS in F Sport trim, which is the most aggressive of all the models. The spindle grille again sits proudly in front. (Apparently, even non F Sport models have mini spindles within the grille design, so we hope you like spindles.) YouÂ’ll also see a new air intake below that grille. ItÂ’s meant to direct air to the brakes and assist in cooling. The slimmer headlights with a new LED pattern look sharp. Along the side, Lexus has implemented new rocker panels that kick up into the rear fender for a more aggressive stance. The view from the rear offers up the most noticeable change. Lexus has gone with the full-width taillight design, stretching the red element from one side of the trunk to the other. Those taillights feature more intricate sculpting, and the rear valance is finished in a glossy black. Lexus changed the exhaust tip look, too, opting for ovals this time. But, onwards to the performance. The powertrain lineup hasnÂ’t changed a bit. A Lexus IS 300 with rear-wheel drive continues to be powered by a 2.0-liter turbocharged four-cylinder. It makes the same 241 horsepower and 258 pound-feet of torque as before, and is mated to an eight-speed automatic transmission only. However, Lexus says itÂ’s been updated for “adaptive transmission control” that is better at choosing the appropriate gear for the driving situation. An all-wheel-drive IS 300 is also available, but itÂ’s equipped with the 3.5-liter V6 that makes 260 horsepower and 236 pound-feet of torque. The all-wheel-drive IS 300 is also continuing to send the power through a six-speed automatic transmission exclusively. The system can send as much as 50% of torque to the front axle. The tip-top IS is the IS 350. ItÂ’s equipped with a 3.5-liter V6 that makes 311 horsepower and 280 pound-feet of torque. With rear-wheel drive, itÂ’s equipped with an eight-speed automatic, but the all-wheel-drive version is equipped with a six-speed auto. Lexus says the rear-drive IS 350 will get to 60 mph in 5.6 seconds, while the all-wheel-drive car gets there in 5.7 seconds.
