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.

Apple uses Logitech steering wheels and pedals to control autonomous cars

SAN FRANCISCO (Reuters) - Apple outlined a plan to train operators of self-driving cars in documents submitted to California regulators earlier this month, the latest clues to the company's autonomous vehicle technology aspirations. Apple was granted a permit to test self-driving cars on April 14 by the California Department of Motor Vehicles but the company has never said anything about its plan. The state released 41 pages of Apple application documents to Reuters that give some clues about the company's highly secret self-driving effort, which it has never openly acknowledged. The iPhone maker joins a long list of carmakers, start-ups and technology rivals, including Alphabet's Waymo, that are testing cars on state roads. Apple is looking for new hit products and autonomous car technology is expected to revolutionize the traditional auto industry. As part of the application, Apple included a 10-page training plan that appeared to be related to operators taking back manual control of the car during automated driving exercises of the system, which it calls a development platform. Business Insider reports that Apple engineers riding in the back seats have the ability to take over control of the car using off-the-shelf steering wheel and pedal video game controllers from Logitech. Apple declined comment beyond the filing. The plan includes a document called "Automated System: Development Platform Specific Training Overview" whose objective is "to train safety drivers in various automated driving conditions." "Development platform will be controlled electronically (e.g. joystick) and safety drivers must be ready to intervene and take control," the document reads. The document highlights different scenarios to be tested, from high speed driving and tight U-turns to lane changes. One letter sent from Apple to the state Department of Motor Vehicles noted that Apple's development platform "will have the ability to capture and store relevant data before a collision occurs." The document does not include detail on how Apple's self-driving platform actually works or other technical details. It also does not say what kind of sensors are found on Apple's three permitted vehicles, all 2015 Lexus model RX450h. The permit does not necessarily mean that Apple itself is building a full car. Apple could instead be designing a self-driving platform that can be integrated into other manufacturer's cars. (By Alexandria Sage.

2022 Lexus GX gets big infotainment update, Black Line Special Edition

The 2022 Lexus GX mostly soldiers on with the same old platform and powertrain as before. But it is finally getting a pretty major infotainment update to help modernize it. Not only that, but it's getting a Black Line edition like other Lexus models with the lovely Nori Green Pearl paint available. That infotainment upgrade is the addition of a 10.3-inch touchscreen. It should be much brighter, higher resolution and more pleasant to use than the quite-old existing unit. It's also accompanied by a revised center stack with more minimalist buttons and switches. The actual infotainment operating system also appears to be from other Lexus models, rather than the one shared with Toyotas. The evidence for this is in the inclusion of the unloved track pad, but you're unlikely to use it much with the prominent touchscreen. Besides the physical infotainment improvements, it also comes with a few feature upgrades. The new system comes with Android Auto and Apple CarPlay compatibility, something that was sorely missing in the previous model year. Navigation is also now standard as are parking sensors and power folding and heated mirrors. Then there's the Black Line Special Edition pictured at the top. Like other Black Line Lexus models, it's mostly a color and trim package, but a fairly attractive one. It comes with gloss black 18-inch wheels, grille surround and roof rails. The door handles are body color, and the bumpers are slightly tweaked design-wise. The taillights are red, rather than clear, and the trim gets an exclusive available color in the aforementioned Nori Green paint. Inside, the GX Black Line has a black headliner, black and grey upholstery, and matte black Ash wood trim. Pricing and availability hasn't been announced yet, but we expect it to go on sale later this year. Related video: This content is hosted by a third party.
