2018 Technology of the Year Award | We chat with Lexus about the LC 500h's hybrid system

Every year, Autoblog editors test dozens and dozens of the newest vehicles available, sometimes even before they're available. From those vehicles, we select the ones we think provide the most innovative technology in the industry. Then we pare the list down to the very best, test them again, and vote on our winner for Technology of the Year. This year, Lexus's multi-stage hybrid system — as tested in the LC 500h — came out ahead of the rest of the finalists. We chose the 2018 Detroit Auto Show to hand over the award to Lexus Group Vice President and General Manager Jeff Bracken. He was kind enough to sit down with Autoblog Senior Editor Alex Kierstein and Green Editor John Snyder at the Lexus stand to talk about the hybrid system, what it does, and what it means for the future of Lexus and Toyota. Check out the video above, and follow along for all our coverage from the 2018 North American International Auto Show in Detroit, where we are taking a look at all of the new cars and technology that we'll see in the near future. Perhaps the next winner of Autoblog's Technology of the Year award is sitting somewhere on the Detroit show floor.

Lexus IS 250 to get new turbo four?

"All show, no go." That's how I described the 2014 Lexus IS 250 F Sport that you see above, when I reviewed it back in November. Don't get me wrong, there's a lot to like about the new IS, but the 204-horsepower, 2.5-liter V6 in the IS 250 is not on that list. In my review, I suggested that Lexus ought to get on the bandwagon of offering a small-displacement, turbocharged, four-cylinder engine in its base IS (like its rivals), and now the folks at Motor Trend are furthering that discussion.
Lexus pulled the wraps off its new NX 200t crossover at the Beijing show recently, and it'll be the first vehicle in the company's lineup to use a brand-new - you guessed it - 2.0-liter turbo-four. With 238 horsepower and 258 pound-feet of torque on tap, that represents a healthy increase over the 204 hp and anemic 185 lb-ft currently being offered with the 2.5-liter V6, and we imagine the fuel economy gains will be rather significant, too. For comparison, the Lexus' four-pot power numbers are very close to the 240 hp and 255 lb-ft offered in the same-sized engine that BMW uses in the 328i.
Motor Trend also posits that Lexus may consider changing the base IS' name from 250 to 200, or perhaps 200t, to properly reflect the new engine's displacement. Of course, that's assuming Lexus doesn't pull a BMW or Mercedes-Benz, and no longer has its alphanumeric names properly reflect the size of the powerplant found underhood.

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.
