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.

Lexus planning a hydrogen fuel-cell LS by 2017

Toyota's Fuel Cell System will certainly migrate to other vehicles in the carmaker's lineup, but Australian car site Motoring reports that one of the models at the head of the queue is the Lexus LS. According to its sources, the executive barge powered by hydrogen will be released by 2017 and take the top spot in the range, rolling in above the LS Hybrid. We're told that Toyota engineers will find a way to slide two hydrogen tanks into its bodywork with the same general setup as on the Mirai – one under the rear seats and another under the rear parcel shelf. The 150-kW fuel cell stack will be placed under the front seats. Motoring says the resulting sedan and its 220-kW electric motor would come in "at around 2,100 kg," which is 4,620 pounds; that's a ginormous 539 pounds less than the listed curb weight of the current LS Hybrid, and 387 pounds more than the standard LS. Assuming all goes as planned, it would have a range of roughly 238 miles, a few dozens less than the Mirai's range of about 300 miles. It would look slightly different, too, the front end getting larger intakes to cool the power unit. It wouldn't surprise us if Lexus does have a hydrogen LS planned – it would be a statement car, and the company likes making statements, even if few heed them; it has stuck with its LS 600h for the past seven years, yet of the 7,539 LS models sold through the end of November this year, only 61 of them were hybrids. The timing would be intriguing, however; by the time the LS hybrid came out, Lexus had already worked over its filet-and-potatoes models. And if the hydrogen version is going to come in above the $120,440 hybrid, well, that will be a statement indeed.

Lexus leads J.D. Power's Vehicle Dependability Study for 2021

J.D. Power's latest Vehicle Dependability Study is out, and, not surprisingly, Lexus sits at the top for the ninth time in the last 10 years. Right behind Lexus is Porsche, followed by Kia, which is the highest-ranked mass-market brand in the study. Genesis, last year's top-ranked brand (in its first year included in the results), fell from first to eighth, though the G80 sedan did earn an award in its midsize luxury segment. The Porsche 911 was called out as the Most Dependable Model by J.D. Power for the second time in the last three years. The vehicles being studied are from the 2018 model year, which means owners have had three years to get to know their cars and trucks. It's notable that this year's study shows a marked improvement in overall vehicle dependability as tracked by J.D. Power. The overall level of problems, scored by the number of problems per 100 vehicles (PP100), declined by 10% compared to last year.  "The study results validate what we have known for some time," said Dave Sargent, vice president of global automotive at J.D. Power. "Automakers are making increasingly dependable vehicles — but there are still some problem areas that need to be addressed and some warning signs on the horizon." Tesla makes its inaugural appearance on the Dependability Study, though its score of 176 PP100 isn't official. Tesla is the only automaker that has chosen not to grant J.D. Power permission to survey its owners in all 50 states. As we've pointed out in the past, the Vehicle Dependability Study includes eight major vehicle categories grouped by J.D. Power as follows: audio/communication/entertainment/navigation (ACEN); engine/transmission; exterior; interior; features/controls/displays (FCD); driving experience; heating, ventilation and air conditioning; and seats. All issues reported by owners are all tracked equally, which means a problematic phone pairing procedure dings an automaker's rating the same as a blown engine or transmission. And in fact, the ACEN category has more reported problems than any other, which means the majority of problems reported don't lead to a vehicle that leaves its owner stranded.
