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.

Toyota recalling 1.67 million vehicles worldwide in 3 campaigns

Toyota is issuing three separate recalls covering 1.67 million vehicles worldwide with most of those models in Japan. It looks like the campaigns' impact on the US may be smaller, though. According to Reuters, Toyota isn't aware of any accidents, injuries or fatalities affecting the models. Some yet-unnamed Lexus models might also be affected.
The largest of the campaigns does not currently affect any US-market vehicles. About 802,000 units of the Toyota Crown Majesta, Crown, Noah and Voxy in Japan are being repaired to replace a seal that could leak in the brake master cylinder. Those already leaking get a new brake booster, as well, according to Reuters.
The only recall currently believed to affect the US is due to a problem covering approximately 759,000 vehicles with 423,000 of them here. The repair is to fix a faulty fuel delivery pipe that could cause a fire if the fuel leaks out. Unfortunately, we don't know which models it covers. Autoblog spoke to Toyota spokesperson Mona Richard and was told the information was still "under embargo." When exactly that embargo will lift isn't yet known, but we're on the case.

2015 Lexus RC F Review

Every year, thousands of people buy two-door coupes that bear the badges of BMW M, Mercedes-AMG, Audi RS, and Cadillac V. These cars are powerful, fast, agile, and - if you believe the marketing - are made to kick ass on the track. But, and this is just my theory, only about 0.2 percent of these owners actually drive their cars the way the companies intended. Most buyers, I think, want the image put forth by an M4 or C63 AMG more than any dynamic abilities. These people just want to give the impression that they're out tearing up the local road course, and a $70,000 sports coupe and a pair of Pilotis are just the ticket. Which is not to say they don't use the performance of these cars, just not the full track-day capabilities. If this describes you, I recommend checking out the new Lexus RC F. This coupe is powered by a 5.0-liter V8, complete with 467 horsepower and 389 pound-feet of torque. These figures, while impressive in a vacuum, are troubling when viewed alongside the competition. The Mercedes-AMG C63 tops 500 in horsepower and torque in S guise, while the six-pot Cadillac ATS-V is nearly equal on power but offers almost 60 more pound-feet of torque. And while the BMW M4 cedes more than 40 horsepower to the Lexus, the RC F doesn't feel as potent from the driver's seat. The RC F doesn't even feel as potent as less-powerful competition. This numerical deficit translates to the stopwatch, where the RC F lags behind the force-induced competition. The C63 and ATS-V both hit 60 in 3.9 seconds, while the BMW takes 4.1 seconds (these are all manufacturer estimates, by the way). The RC F needs 4.4 seconds to hit 60 miles per hour. The only vehicle in this segment that's slower is the Audi RS 5, and that's been on sale longer than all its current competitors combined. And the Audi's charms (oh, that glorious engine note) help you overlook its lack of pace. The RC F doesn't have the aging Audi's charisma, making its lack of both perceived and actual pace more glaring. I'm placing blame on this car's overbearing induction sound. It was a neat trick on the original IS F – this car's predecessor – but over the years it's just become kind of played out. At the least the noise is real, piped into the cabin via a resonator, but it sounds too artificial. And the point at which it kicks in is entirely predictable. Neither of these traits contribute to an involving driving experience.
