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.

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.

Here are this year's top 5 automaker April Fools’ jokes

April 1 is the wonderful day when PR departments really push themselves to top the zany jokes they came up with the previous year. And it's not just fast-food chains competing with each other, or breweries announcing they have released stuff like a fermented herring flavored beer: carmakers' media teams rarely miss out on the opportunity to play a little joke on their audience. Here are a few of our favorites from this year:1) Porsche Porsche announced that it's launching a Mission E tractor, styled to resemble its 1950s tractor models. "With a power output in excess of 700hp, the Mission E Tractor will be the fastest accelerating agricultural vehicle in the world, enabling farmers to harvest crops in record time with the added environmental benefits of zero emissions at source and significantly reduced operating noise."2) Lexus Lexus actually jumped the gun, telling us on March 28 that it's combining cars and drivers using DNA matching. The kicker was that with DNA-matched cars, owners would be able to start their Lexuses by licking the steering wheel.3) McLaren Automotive McLaren said it's boosting efficiency by quite eccentric measures, such as measuring the technology center's lake and floor tiles daily, and by synchronizing the staff's tea breaks.4) BMW Motorrad BMW's motorcycle arm is solving parts availability issues in remote locations by offering a 3D printer mounted permanently on the bike's rack: If you need to replace a broken-off gear lever, you can just print one. "The new system will mean that even very rarely required parts not generally stocked by BMW Motorrad sales partners can be supplied on a just-in-time basis." BMW even went to the lengths of announcing that the "BMW Motorrad iPart 3D Mobile Printer" was tested on the Antarctic, by erecting a tent whose poles were produced onsite.5) Honda Last but not least, Honda UK purportedly cut the roof off a new CR-V, calling it the CR-V Roadster. Tellingly, no convertible top was even offered for the concept, "making it a no-top rather than a drop-top. This innovative design makes it a vehicle purely for sunnier climates and therefore completely useless for the two-day British summer which traditionally occurs in May."Related Video: Featured Gallery Top 5 April Fools 2018 Image Credit: Porsche Green Humor Weird Car News BMW Honda Lexus McLaren Porsche bmw motorrad mclaren automotive
