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.

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.

Lexus confirms three-row RX coming by 2018

Now seems like the perfect time for Lexus to launch a three-row version of its RX crossover. Not only are CUVs flying off of dealer lots – as you probably already know, the RX is Lexus' best-selling model – there aren't all that many car-based luxury soft-roaders on the market for Lexus to compete with. Problem is, these things take time, and product planners don't always get the new-model cadence just right. Now, though, we at least have a tentative date for the extended-wheelbase 'ute's arrival. According to Automotive News, Lexus General Manager Jeff Bracken has confirmed that the brand is readying a three-row version of the RX with plans to have it in the clutches of salivating dealers by late 2017 or early 2018. Chances are, the new model will wear RX 350L badges in gas-powered guise and carry the RX 450hL moniker in hybrid form. As AN points out, these names were registered as trademarks earlier this month. That indicates we'll see both standard V6 and optional hybrid-powered versions of the three-row RX. Not only will the extended RX keep the same nomenclature, it'll also look pretty much the same as its five-seat siblings. According to Bracken, "We put so much energy into the styling you see now that we didn't want to compromise even with the third row." All we have to do now is wait, said Bracken. "They would just love to have it now. But I think they're quite relieved that they know it's coming." Related Video:
