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.

2019 Toyota Avalon vs. full-size sedans: How they compare on paper

Full-size sedans aren't exactly in great demand at the moment, and at least one of the vehicles in this comparison has been rumored to be on the endangered species list. Yet, we've just had our first drive in the 2019 Toyota Avalon, and if anything has a chance of rejuvenating the segment a bit, it's an all-new version of what has long been the segment's benchmark. To see how the new Avalon compares, we've put together the below spreadsheet featuring the Avalon's primary apples-to-apples rivals, the Buick LaCrosse and Chevy Impala. We also included the Nissan Maxima, which is comparable in price, sales and non-luxury badge, and which offers the sort of increased driver engagement promised by the new Avalon XSE and Touring trim levels. We also included the outgoing Avalon for reference as well as that car's luxury cousin, the Lexus ES, which can definitely be cross-shopped with the luxuriously trimmed Avalon Limited. You can use our Compare Cars tool to create your own comparison, such as one featuring the rear-wheel-drive Chrysler 300, Dodge Charger or even Kia Stinger. Alright, enough chit chat. On to the spreadsheet. Performance and fuel economy The GM sedans may come standard with four cylinders, including a mild hybrid system in the LaCrosse, but puh-lease. The V6 is the name of the game in this segment, with outputs now surpassing the 300-horsepower mark. The LaCrosse is the horsepower and torque champ, though it also weighs a bit more than the new 2019 Avalon, so acceleration is likely to be comparable. The Impala weighs a lot more and has only a six-speed automatic, so despite having a wee bit more power, one should expect it to be pokier (not a good sign for a car rumored to be on the chopping block). One would expect the Maxima's 300 hp and lowest curb weight to result in the quickest acceleration, but then it's also strapped to a CVT, which despite being better than ever, is still a CVT. Things get worse for Chevy when you consider the Impala's base four-cylinder gets the same 25 mpg combined as the Avalon's V6 — once again a segment best. Now, should you really prioritize fuel economy, the 2019 Toyota Avalon Hybrid really stands out with a 43 mpg rating (or 44 with the base XLE trim) that bests the outgoing Avalon Hybrid. Honestly, after driving this new Hybrid, it actually seems like it would be the best bet for most buyers. There's sufficient power, and it only costs $1,000 more than the comparable V6 version.

Lexus LC convertible could appear in 18 months, LC F to follow

Auto Express reports that Lexus has a approved a convertible version of the LC, and is close to green-lighting a high-performance LC F trim. The Detroit Bureau reported that the same two models were in development one year ago, citing Lexus sources at the Detroit Auto Show who told the outlet "a number of additional variants" would follow the coupe's launch. The timeline's been stretched a bit between then and now; instead of getting the convertible this year, Auto Express says the "done deal" droptop should arrive in 18 months to two years. It's harder to read what we might get in an LC F. Gossip is that the naturally aspirated, 467-horsepower, 5.0-liter V8 wouldn't be the right motor for a hot LC. That V8 serves in lower-tier F models. so word is that Lexus engineers are considering a 4.0-liter, twin-turbo V8 with around 600 hp. Lexus chose the BMW 650i, Mercedes-Benz S-class coupe, and Jaguar F-Type as competitors to the LC, all of which have convertibles and high-performance trims. Among the specially-tuned challengers, the Jaguar F-Type R comes in with the lowest power figure at 550 hp. Both models would return Lexus to a small, exclusive end of the market where it hasn't held a membership since 2010. Rejoining that soiree — a party hosted by the Germans, because these matters always come back to the Germans — is another huge, and costly, step toward shedding Lexus' somnolent image. Akio Toyoda said the goal for his luxury arm was "that the words 'Lexus' and 'boring' never appear in the same sentence again." A three-model lineup would give the LC a genuine chance to contribute to that aim.
