2018 Lexus LS 500 F Sport Drivers' Notes Review | Pretty but imperfect

The ultimate Lexus, and the one that launched the brand, the LS was completely redesigned for the 2018 model year. It introduced an aggressive version of the famous (infamous?) "spindle" grille, a swoopy interior, and went to a completely V6-powered lineup, the fully gas-powered model featuring a twin-turbocharged 3.5-liter engine. Not only that, but it adopted the platform of the stunning Lexus LC 500. With all that in mind, the LS 500 sounds like it's got the potential to not only be a first-class luxury cruiser, but may have even gained some of the LC 500's sporting expertise. To find out, we spent some time in an all-wheel-drive model with the F Sport package, which adds a meaner-looking grille, sporty seats and the trick sliding gauge ring to remind us of the LFA supercar that first used such a cluster. The only thing it lacks is the handling upgrades exclusive to the rear-drive gas-only LS. Associate Editor Joel Stocksdale: I love the Lexus LC 500, like, a lot. It was my favorite car I drove last year because it has the perfect combination of style, comfort and performance. So knowing that the LS has LC roots, I was excited to drive it, hoping it would basically be a four-door version of that car. It certainly looks the part. Though not the gorgeous beast the LC is, it's still a looker. It's aggressive and intimidating, particularly with the black F Sport grille. And when you get in, you're greeted by hip-hugging leather seats and a flashy instrument cluster. Everything around you is leather, suede or metal in really interesting, unique shapes that make this Lexus feel like something different and special to most luxury cars. I particularly like the floating arm rest/grab handles in the doors. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. But things fall apart with the driving experience. The twin-turbo V6, although plenty powerful, doesn't sound nearly as lovely as the growling V8 monster in the LC. It also has really sluggish throttle response, and the gearbox doesn't shift as quickly and crisply as in the LC, even in Sport+ mode. The steering refuses to tell you anything either, feels too light, and what weight exists feels very artificial. The ride quality also doesn't quite seem to know if it wants to be La-Z-Boy cushy or sports sedan firm.

Toyota announces new, more efficient powertrains for 60 percent of its vehicles by 2021

In the face of increasingly strict standards on fuel economy and CO2 emissions, Toyota announced today that it's introducing a new hybrid system, a new 2.5-liter direct-injection inline four-cylinder engine, and two new transmissions – an eight- and a 10-speed. The development of all of these components will be based around the Toyota New Global Architecture, or TNGA. Development of the systems has moved forward and the new powertrains will find their way into vehicles starting next year. TNGA, like Mazda's Skyactiv technology, is a complete design philosophy that focuses on more than just a clean or efficient engine. The first vehicle to deploy the TNGA platform was the current, fourth-generation Prius. With TNGA, Toyota focused on improving handling, ride, and braking performance. The new powertrains are meant to compliment this new platform by being both engaging to drive and fuel efficient. Since TNGA can be adapted for front-, rear-, or all-wheel-drive layouts, it's capable of underpinning a number of potential products. Toyota is arguably the leader in hybrid technology, and taking lessons learned in the development of the current Prius, the automaker has developed the new Toyota Hybrid System II, or THS-II, for rear-wheel-drive applications. Performance has improved versus the outgoing model, and Toyota says efficiency, especially at high speeds, has been improved. In addition, the system's use in plug-in vehicles has been improved. For the first time, the electric motor will be able to provide direct driving power, whereas before it simply acted as a generator. The new, naturally aspirated 2.5-liter four-cylinder, like the THS-II, has been designed around the TNGA platform. Most notably, the thermal efficiency of the engine has been improved. This means a higher output and improved exhaust and cooling. The new engine, which works in both traditional and hybrid applications, will proliferate through the Toyota and Lexus lineup. Toyota's two new automatic transmissions, like the new engines, are based on the TNGA system. That means a lighter and more compact design relative to similar transmissions. The 10-speed is intended for rear-wheel-drive Lexus products like the GS and LS. The tuning has been adjusted to improve response and smooth out shifts, though it's impossible to say how much it's been improved without getting behind the wheel.

Google shares more details on self-driving car accidents

Google has pledged to release monthly reports on the status of its self-driving car program, and says these updates will include information on accidents involving the vehicles. But the company won't release the actual accident reports, a sore point for activists who recently have clamored for the company to be more transparent in the way it tests this promising technology on public roads. "Google is dribbling out bits of information in the hope to silence legitimate calls for full transparency," said John Simpson, privacy director for Consumer Watchdog, a nonprofit that has asked Google to release reports from the 12 accidents the company says it has been involved in over the past six years. "They are testing on public roads, and the public has a right to know exactly what happened when something goes wrong." Under California law, the accident reports are not considered public records. Google has attributed all accidents to human error, and says drivers of the other cars involved caused 11 of the 12 accidents. In eight of those, the Google cars were rear-ended, and the autonomous vehicles were sideswiped in two other crashes. One of the accidents occurred at an intersection when a human driver failed to yield at a stop sign, and in one incident, a Google driver accidentally rear-ended another car while manually driving. Google had previously provided those details. The first monthly report installment sheds new light on which types of self-driving vehicles were involved, directions of travel, locations, and whether the cars were operating in autonomous or manual mode. Update: Google says this information comes directly from the OL 316 forms used to report accidents involving autonomous cars in California, though it has "edited the summaries lightly to protect other drivers' information." But Google still will not release the original OL 316 forms, nor the "traffic collision report" forms used in California to report accidents. Another company that has been involved in a single self-driving car accident, Delphi Automotive, has released this information, which verified its car was not at fault. Regarding Google, Simpson said, "We now know a few more details of what happened. The problem is that it's Google's version and they want us to take their word for it." The Google self-report adds information that goes beyond accidents, with further details on the company's overall program.
