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.

Junkyard Gem: 1992 Lexus SC 400

After Toyota stunned the automotive world with the Lexus LS 400 in 1989, offering a majestically engineered luxury sedan with an all-new DOHC V8 at less than half the cost of its Mercedes-Benz 560 SEL rival, what could be done to follow that (other than a money-printing Lexus-badged Camry, that is)? Clearly, the missing piece of the Lexus branding puzzle at the time was a sports coupe, something to extract the money of car shoppers considering, say, a new Mercedes-Benz 300 CE or Acura Legend coupe. That car turned out to be the Lexus SC, styled in California and known as the third-generation Toyota Soarer in Japan. Here's one of the very first SCs sold in the United States, found in a Denver-area self-service yard last month. These cars had intimidatingly good build quality (I know, because I dismantled a '92 SC 400 down to its smallest components a while back), clearly designed to last at least a quarter-million miles with routine maintenance. This one got hit hard in the right rear, however, and it wasn't worth repairing the damage to a non-SUV pushing three decades of age. Americans could buy a six-cylinder version, the SC 300, which came standard with a five-speed manual transmission (almost all buyers "upgraded" to the automatic, of course). This car is the SC 400, which means it has the same 1UZ-FE V8 engine as the LS 400. That's 250 super-smooth horses and six-bolt main bearing caps keeping the crankshaft from going anywhere it shouldn't. The SC 400 never was available with a manual transmission, nor was its SC 430 successor. This one has the mandatory Aisin-Warner four-speed automatic. This content is hosted by a third party.

These cars were very quiet and comfortable and they could cruise all day at triple-digit speeds, but a curb weight pushing 3,600 pounds meant that the SC 400 wasn't going to beat its Porsche 928 rival on a race track. Actually, the 1992 928S4 cost more than twice as much as the 1992 Lexus SC 400 ($80,920 versus $37,500) and had both a more powerful (326hp) V8 and available manual transmission; perhaps the 1992 Cadillac Eldorado Touring Coupe ($32,470, 200hp V8, automatic) was a more realistic sales rival for today's Junkyard Gem.

Florida police officer injured by DUI suspect after traffic stop

What started as a fairly normal traffic stop for Sergeant Kerstan Tatro ended with him lying on the ground with a compound fracture in his arm. The policeman in Gulf Breeze, FL, pulled over a woman driving a Lexus SC 430 because her erratic driving suggested that she might be under the influence. It all went well until Tatro asked the driver to perform a field sobriety test and she sped away partially trapping the officer in the car. It was all captured by the cruiser's dashcam. As the woman started to drive away, Tatro tried to grab for the keys. He was too late, though, and she got on the gas. The Lexus ran over the officer's foot and caused the serious injury to his arm. Thankfully, bystanders were at the policeman's side within a few seconds of him being hurt. By coincidence, even Tatro's daughter was driving by the time, and was pretty shaken by her dad's condition. According to the Pensacola News Journal, a witness to the officer's injuries followed the woman to a hotel parking lot and told police where she was. They allegedly found drugs in her possession. Below is a video from the Pensacola News Journal interviewing Tatro, and he gives a thorough account of exactly what happened. This content is hosted by a third party.
