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.

2016 Lexus RX First Drive [w/video]

There is no more important model line to Lexus than the RX. Year to date, with a replacement on the way, the RX accounts for 28 percent of the brand's sales. It's the undisputed champ of the midsize luxury SUVs, nearly outselling BMW's entire SUV lineup. So when it came time to push a significant update to its best-seller, Lexus put the whole of its engineering might into the challenge. The 2016 RX represents the very best that Lexus is capable of, specifically when its spindle-shaped grille is pointed at its core audience. Starting with the basics, Lexus increased the exterior dimensions. Wheelbase grows just under two inches while overall length goes up by five. But overall interior space remains exactly the same at 139.7 cubic feet. Rear-seat passengers get extra space – head, hip, and legroom all nudge up slightly for 2016 – but it comes at the expense of cargo area, at least on paper. Whereas the 2015 RX offered as much as 80.3 cubic feet of storage space with the rear seats folded, the 2016 model cuts that by a quarter to 56.3 cubes. Lexus representatives say that cargo space is up, and the numerical reduction is due to different measurement methods. The 450h's cargo area is smaller by a negligible half cubic foot due to the location of the car's battery pack. The new RX looks seriously chiseled. RX buyers and their friends enjoying the more spacious back seat are going to look considerably more stylish in 2016. The new RX looks seriously chiseled, with sides creased and cut to the point that there's hardly any flat surfaces. It's hard to pick favorite details, but we really like the upward-kick of the rocker panel. At the front lives Lexus' ubiquitous spindle grille, more exaggerated than ever before and rimmed by a strip of thick chrome. Sharp lines dominate the rest of the fascia, from the slit-like headlights to the arrowhead-shape that surrounds the fog lamps. There is a premium lighting package that includes LED lamps everywhere not to mention awesome sequential turn signal indicators in the taillights. UPDATE: It turns out the awesome sequential turn signal indicators aren't going to be available in the United States, which is a big bummer. If the floating roof looks familiar, that's because you've seen it on the Nissan Murano. Somehow the massive proportions of the trademark Lexus grille is not the most controversial styling element of the new RX.

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.
