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 IS 250 to get new turbo four?

"All show, no go." That's how I described the 2014 Lexus IS 250 F Sport that you see above, when I reviewed it back in November. Don't get me wrong, there's a lot to like about the new IS, but the 204-horsepower, 2.5-liter V6 in the IS 250 is not on that list. In my review, I suggested that Lexus ought to get on the bandwagon of offering a small-displacement, turbocharged, four-cylinder engine in its base IS (like its rivals), and now the folks at Motor Trend are furthering that discussion.
Lexus pulled the wraps off its new NX 200t crossover at the Beijing show recently, and it'll be the first vehicle in the company's lineup to use a brand-new - you guessed it - 2.0-liter turbo-four. With 238 horsepower and 258 pound-feet of torque on tap, that represents a healthy increase over the 204 hp and anemic 185 lb-ft currently being offered with the 2.5-liter V6, and we imagine the fuel economy gains will be rather significant, too. For comparison, the Lexus' four-pot power numbers are very close to the 240 hp and 255 lb-ft offered in the same-sized engine that BMW uses in the 328i.
Motor Trend also posits that Lexus may consider changing the base IS' name from 250 to 200, or perhaps 200t, to properly reflect the new engine's displacement. Of course, that's assuming Lexus doesn't pull a BMW or Mercedes-Benz, and no longer has its alphanumeric names properly reflect the size of the powerplant found underhood.

2015 Lexus NX 300h

With so much hullabaloo being made over the first gasoline turbocharged engine produced by Lexus, it's easy to forget that there's another option for those who'd rather (barely) hear the whirring of electric motors than the high-pitched whizzing of turbos. That's too bad, because we think the NX 300h is one of the more interesting hybrids on the market, due in large part to its innovative all-wheel-drive system and relatively sporty driving dynamics. We spent several hours with the brand-new hybrid crossover from Lexus, and we came away with plenty to talk about.
Driving Notes
Of course, the big thing that differentiates the 300h from the 200t is its drivetrain. In place of the 2.0-liter turbocharged four-cylinder sits a 2.5-liter gasoline engine that runs exclusively on the Atkinson cycle to save fuel, augmented by a pair of electric motors and mated to an electronic continuously variable transmission. Lexus is no stranger to hybrids, buoyed by parent company Toyota's expertise, and the basic setup used by the NX 300h is a well-known quantity shared with the ES 300h.
