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 LC 500 gets customized at SEMA before it even goes on sale

We still have to wait until next year for Lexus to start delivering the gorgeous new LC 500 to dealer showrooms, but that little fact didn't stop Lexus from letting people modify it for SEMA. The first LC coupe to get the custom treatment is this bright yellow example modified by Gordon Ting and Beyond Marketing. Prospective LC 500 buyers who want to modify their rides won't have to wait long do start adding these parts to their cars. Because Lexus let these companies develop parts this far in advance, the parts should be available around the same time as the car. On the outside, the LC 500 gets a new Artisan Spirit body kit that consists of a front diffuser, fender flares, side skirts, rear diffuser and rear spoiler. The car also has a lower stance thanks to a kit developed by KW Suspension. It features adjustable springs for ride height, plus a hydraulic lift system to keep the custom body work from scraping. The Lexus rolls on HRE P101 wheels that are stopped by Brembo brakes. The other highlight of this custom Lexus is under the hood. The LC 500 comes with a 471-horsepower 5.0-liter V8 that's also found in the RC F and GS F. However, the engine development team at Hard Media, Inc. and D SPORT Magazine had the engine rebuilt with CP pistons and Carrillo connecting rods, and it was given new cylinder sleeves from LA Sleeves to increase bore-size. The end result is a 5.6-liter engine making 525 horsepower. According to Lexus, 525 horsepower is far from the limit of this engine, saying that its capabilities could be, and in fact "have been more than doubled." If anyone at Lexus is reading this, we don't doubt the claim, but we'd also be more than happy to see this capability proven. Perhaps at next year's SEMA show?

The Lexus LC 500h has a four-speed auto and that's a good thing

Lexus is sharing some powertrain details on the LC 500h ahead of the big hybrid coupe's debut in Geneva. Its new gas-electric setup strays from Toyota's tried-and-true system found in everything from the Prius to the Lexus GS. It's called the Multi Stage Hybrid System that's designed for performance vehicles, and it has an antiquated-sounding piece of equipment buried deep inside that's supposed to make it more enjoyable to drive. The basics: In the LC 500h, its first application, the Multi Stage Hybrid System will consist of a 3.5-liter V6, a hybrid transmission, and a lithium-ion battery pack. The hybrid transmission has an electric motor for motivation (and we're guessing a second for charging) and a four-speed automatic mounted to its rear, which either means inside or aft and in series. Why add ancient tech to a new hybrid system? Lexus says it preserves the connection between throttle input and engine speed that gets lost in a CVT. And while four seems like an insignificant sum in the face of nine- and 10-speed autos, remember that it is an infinite increase in gear count compared to CVT-packing hybrids. Toyota has been using versions of the Hybrid Synergy Drive system since the first Prius debuted in 1997, and the same system is sold under the Lexus Hybrid Drive banner in most of the luxury brand's offerings. These systems use what Toyota calls an e-CVT – two electric motors paired with a planetary gearset. This lets the engine and electric motors share the job of propelling the car – one motor handles charging of the battery and the other is primarily used to drive the wheels but can also recoup energy through regen. Like a conventional CVT, the planetary gearset arrangement allows the gas engine to run at its optimal engine speed when called upon for motivation and/or charging. But that doesn't make for the most exciting or familiar driving experience, as it affects both power delivery and the sound of the power being delivered. This is where the four-speed auto comes in. Based on the limited details Lexus has shared, our hunch is that the hybrid transmission will meld some form of the existing Lexus Hybrid Drive system with two more planetary gearsets, or the basic guts of a four-speed auto. This will provide the four fixed ratios and the feeling of actual shifting gears – because there will be actual gears shifting.
