Google self-driving Lexus crashes into a bus

Google's self-driving cars have been in accidents before, but always on the receiving end... at least, until now. The company has filed a California DMV accident report (PDF) confirming that one of its autonomous vehicles (a Lexus RX450h) collided with a bus in Mountain View. The crash happened when the robotic SUV had to go into the center lane to make a right turn around some sand bags – both the vehicle and its test driver incorrectly assumed that a bus approaching from behind would slow or stop to let the car through. The Lexus smacked into the side of the bus at low speed, damaging its front fender, wheel and sensor in the process. This was a minor incident, and we're happy to report that there were no injuries. However, this might be the first instance where one of Google's self-driving cars caused an accident. If so, the Mountain View crew can no longer say it's an innocent dove on the roads -- while this wasn't a glitch, its software made a decision that led to a crash. We've reached out to Google to see if it can elaborate on what happened. No matter what the response, it was always going to be difficult to avoid this kind of incident. Until self-driving cars can anticipate every possible road hazard, there's always a chance that they'll either be confused or make choices with unexpected (and sometimes unfortunate) consequences. However, the hope at this early stage isn't to achieve a flawless track record. Instead, it's to show that self-driving cars can be safer overall than their human-piloted counterparts.Related Video:This article by Jon Fingas originally ran on Engadget, the definitive guide to this connected life.

Lexus exploring PHEV, full EV and fuel cell versions of LS flagship

After four years of rumors about a Lexus LS powered by a hydrogen fuel cell, the chief engineer of the flagship sedan says the carmaker's working on even more options. Toshio Asahi told Australia's GoAuto that three alternative powertrains — plug-in hybrid, full electric, and hydrogen — are "all on the table" for consideration. Asahi wouldn't give any timeframes, but whenever they arrive, additional drive options would fill out the LS range to better contend with the Germans. Years of reports predicted this fifth-generation LS would get hydrogen power. A Motoring article at the end of 2014 forecast a fuel cell LS to arrive by 2017. In 2015 Japan's Nikkei newspaper reported that Lexus was considering a fuel cell option to arrive in 2020, around the time of the Tokyo Olympics. Later that year, at the Tokyo Motor Show, Lexus showed off the LF-FC concept, powered by a cell and stack arranged for "optimum front-rear weight distribution for a sporty saloon." GoAuto said that during that show, a Lexus executive said an FCEV powertrain would end up in production "sooner than you think." The following year, Autocar reported we'd see a production version of the LF-FC "on sale before 2020" as a replacement for the LS, and last year, Lexus trademarked the name "LF-FC Concept." The intel gets murkier regarding plug-in hybrid and full electric versions. We now know Lexus is working on a more powerful hybrid system. The current hybrid produces a total system 354 horsepower and 258 pound-feet of torque using the same 3.5-liter V6 in the standard car as a base, though the standard car adds two turbos for 415 hp and 442 lb-ft. The coming hybrid will likely use the twin-turbo setup and could achieve two important ends: Smoothing out noted issues of powertrain refinement, and at least matching the power specs of Mercedes-Benz and BMW flagship plug-in hybrids. That hybrid LS would still miss out on the all-electric driving of its rivals. If there really is an LF-FC coming in the next two years, it would seem a perfect time to retire the conventional hybrid and introduce a plug-in version embodying the velvet sophistication Lexus is known for. The battery electric LS is a big question mark outside of Lexus HQ. Last year Toyota announced a breakthrough in solid state battery technology, the carmaker announcing it wanted such batteries on the market by 2022.

2016 Lexus RC 200t Quick Spin

Cars like the BMW 4 Series, Cadillac ATS coupe, and Audi A5 exist not as volume cars, but as aspirational products designed to draw in the young and the young at heart. The humble four-cylinder turbo, offered in each car listed above, provides an accessible point of entry for lifestyle buyers that want the statement of a sporty coupe without the eagerness, fuel inefficiency, or cost of a big six-cylinder engine. Now, Lexus is throwing its hat in the ring with a turbocharged version of its polarizing RC coupe. We took the new RC 200t out for a day on the winding roads of the Pines to Palms Highway near Palm Springs, CA, and found that while Lexus' new engine will draw new customers, they probably won't like what they find. Driving Notes The RC joins the IS, GS, and NX as members of Lexus' four-cylinder turbo clan. There's 241 horsepower and 258 pound-feet of torque on offer here, numbers that compare favorably with the BMW 428i (240 hp and 260 lb-ft) and Audi A5 (220 hp and 258 lb-ft). None of that matters, though, because the turbocharged RC is easily the slowest car in its class. You'll struggle to keep pace with stuff like the Hyundai Veloster Turbo. The RC 200t somehow takes 7.3 seconds to get to 60 miles per hour. That's a second slower than the A5, and over half a second slower than the 4 Series or Cadillac ATS. You can't drive a car that looks as wild as this and take that long to get to 60. Blame it on the RC's 3,737-pound weight. Lexus only saved 11 pounds by switching out a 3.5-liter V6 for the 2.0-liter turbo. The BMW and Cadillac both weigh well under 3,500 pounds. Even the RC's four-door fraternal twin, the IS 200t, is 150 pounds lighter (and only takes 6.9 seconds to get to 60). The RC needs a diet, plain and simple. If Lexus truly wants to compete against the Germans and Cadillac, a snappier transmission is in order. Like the GS we talked about yesterday, the Aisin eight-speed is fine on upshifts – it's still not as fast as the 4 Series' ZF eight-speed auto – but it suffers when it's time to change down. Around town, it's less of a problem, but on the twisty mountain roads outside of Palm Springs and on the freeways, the RC's gearbox kept tripping over itself. We'd love to see what the 2.0-liter turbo engine could do in a lighter car, because it's a real charmer. The broad 1,650-to-4,400-rpm torque peak gives drivers a lot of space to play, although the RC does feel flat-footed as you crest 5,000 rpm.
