Toyota shows a smoother autonomous Lexus for CES

Toyota is bringing a new research vehicle to CES. The TRI-P4 autonomous driving test vehicle, based on the Lexus LS500h, is a major step ahead, according to Toyota, as it has improved computing power and additional cameras for better reaction times. Earlier test mules have also used the LS as a basis, and the shift to the new, fifth generation LS brings chassis and steering-control benefits, so the vehicle's movements are smoother in automated mode. The camera tech has also been better integrated into the vehicle design, courtesy of CALTY in Ann Arbor, Michigan. Development has been swift, as the TRI's P2.1 car was unveiled in 2017. The P4 car will be used for Toyota Research Institute's Guardian and Chauffeur mode development. The two tiers differ somewhat, as TRI's Ryan Eustice explains: "Our Chauffeur development is focused on full autonomy, where the human is essentially removed from the driving equation, either completely in all environments, or within a restricted driving domain. Guardian, on the other hand, is being designed to amplify human performance behind the wheel, not replace it. The introduction of the new P4 platform will help us accelerate the development of both tracks when it joins our fleet this spring." The vehicle's situational awareness is boosted by two extra cameras facing on the sides, and a new imaging sensor both forward and rearward. Toyota says the P4's lidar setup is a carryover from the previous platform, but that its machine learning is much improved by its more powerful computer setup. The electricity required by the P4's computing power also comes from the hybrid battery, and as the computer "brain" is now housed vertically against the rear seat's backing, actual trunk space has been freed. More LS500hs will begin to be modified into TRI-P4 vehicles during spring 2019. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

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.

2018 Lexus RX 350L, RX450hL are here to fill your 7-seat needs

The Lexus RX is the Japanese automaker's best-selling model, moving nearly twice as many units so far this year as the runner-up, the Lexus NX. Considering the state of the crossover-crazed market, that should be a surprise to absolutely no one. Still, customers demands more, and automakers are happy to deliver. Currently, Lexus has a three-row crossover-shaped hole in its lineup. Soon, that gap will be filled by the new seven-passenger 2018 RX 350L and RX 450hL. Sure, you can get three rows in the GX and LX, but traditional SUVs like that aren't selling nearly as well as more fuel efficient and more affordable car-based crossovers. The RX 350L and RX 450hL are based on the standard and hybrid RX variants. The pair have been extended by 4.3 inches to help accommodate an extra pair of seats. The angle of the rear window has also been changed to make sure third-row occupants have a reasonable amount of headroom. The RX's second row folds in a 40/20/40 split. Access to the third row is granted with a lever that slides the second row up and forward. The second row also sits slightly higher than the third, creating some much needed footroom. Tri-zone climate control is available, and gives those in steerage control of their own ventilation. A pair of cup holders keeps drinks from ending up in the hair of those sitting up front. The third row folds flat when not in use. Like the standard RX 350, the RX 350L is powered by a 290-horsepower 3.5-liter V6 and is available in both front- and all-wheel drive. The RX 450hL comes standard with all-wheel drive. It's powered by a 3.5-liter V6 and two electric drive motors. Total power output is 308 horsepower. An EV mode allows the hybrid to run on pure electricity for a short amount of time. The models go on sale early next year.
