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 goes from land yachts to water yachts with this boat concept

Just this week, Lexus unveiled its fully redesigned flagship, the LS sedan. But the term "flagship" seems a bit misplaced now that Lexus has revealed an actual ship. Well, the Lexus Sport Yacht may be a bit small to be called a ship, but it's as close as many automakers will get. According to Toyota, the idea for the boat came about when the company's CEO, Akio Toyoda, was trying out one of the marine division's new yachts that use Toyota diesel engines. He wanted to see what a sporty, luxury yacht using Lexus design would be like. At his behest, the Toyota Marine Department and Lexus got to work on the concept you see here. More than a clay model, this is a fully-functional nautical machine. The Lexus Sport Yacht was constructed from carbon fiber by Marquis-Carver Yacht Group in Wisconsin, and has a pair of V8 engines shared with the Lexus RC F (and GS F, and LC500). You can even see through the clear engine compartment cover that they share the same bright blue-painted intake manifolds. Compared with the automotive applications, each engine makes a bit less power at 440 horsepower. When you have two of them, though, that becomes less important. Together the engines' roughly 880 horsepower can propel the boat to a top speed of 49 mph. The Lexus Sport Yacht comes complete with many luxury amenities. There's seating for eight on the deck. Two of those seats fold out from either side of the captain's chair "for very special guests." The captain also has access to a pair of touchscreens, a small one in the wheel and a massive one ahead of it for instruments and other information. Down below, the forward passenger cabin is loaded with leather, wood, air conditioning, a table, and sofa seating for six. The yacht's galley has a sink, refrigerator, and stove, and the bathroom comes complete with a shower. Don't expect to see the yacht on sale anytime soon, since this is just a concept at the moment. That being said, luxury automakers, including Aston Martin and Mercedes, have started competing in the yacht market. And while Toyota's marine division hasn't built a pleasure boat since the Epic line, it probably wouldn't be too difficult for the company to start building this Lexus. Related Video:

Lexus RC F police cruiser set to patrol Australia's highways

Planning a trip down to Australia? Better keep an eye on the speedometer. Because with this latest set of wheels, the local cops should have little trouble chasing you down. It's a Lexus RC F coupe that's been specially outfitted to join the police motor pool in the southern region of New South Wales. Details on how it's set up for official duty are scarce, but as you can see, it features special graphics as well as flashing lights on the dashboard and rear shelf. There's probably special communications equipment installed as well, but we doubt the Aussie bobbies will be trying to squeeze any perps into the back seat. The Japanese performance coupe is slated for use in a number of applications, one of them being to promote road safety. We're not sure how a 467-horsepower V8 luxury coupe gets that message across, exactly. But even though it's not quite as impressive as what they've added to the fleet in Dubai, the RC F ought to garner some attention at events like the Bathurst Six Hour race and the MS Sydney to the Gong bike ride where it'll be on display. And just in case it's put on highway patrol, we'd suggest locals and visitors exorcise their speed demons on the Stuart Highway up north and keep their right feet light on the streets in NSW.
