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.

2018 Lexus LC 500h is a wonderful mechanical mishmash

Lexus is following up on the Detroit debut of the LC 500 with a Geneva debut for a new hybrid model that, yes, has a four-speed automatic. We're still getting used to the idea, too. But as we've explained before, even with the old-school gearbox there's some real cutting edge stuff going on here. While the LC hybrid will have a four-speed auto, it will work in conjunction with an eCVT, a Lexus hybrid system, and possibly black magic. It's all very complicated – you can get particulars here – but it's best to think of the LC 500h's transmissions not as a CVT and a four-speed auto, but as a sort of ten-speed hybrid of the two, since both systems are always engaged. The hybrid system is much more familiar. There's a 3.5-liter V6, a battery pack, and two electric motors. Total system output is 354 ponies and Lexus claims the sprint to 60 mph will be done in under five seconds. For the record, the gas-only LC is projected to do the deed in around 4.5 seconds, so the hybrid shouldn't be a dramatic compromise in terms of performance. Of course, stats only tell so much. The ultimate question for the LC 500h is how its wild mix of transmissions, batteries, motors, and an engine will behave on the road. We don't have an answer for that yet, but we do have live images of the new hybridized Lexus at the 2016 Geneva Motor Show. Check them out.

The LC 500h is equipped with Lexus' next generation hybrid powertrain, the Lexus Multi Stage Hybrid System, providing enhanced driving pleasure, more performance, and greater efficiency. The LC was first revealed at the 2016 North America International Auto Show. Its styling, performance and craftsmanship position the vehicle as Lexus' flagship coupe. The LC also utilizes Lexus' new architecture that promises enhanced dynamic capability. Inspired by the acclaimed LF-LC concept that debuted in 2012, the LC represents a shift in Lexus' engineering processes and design ideologies, and marks the beginning of a new phase for the Lexus brand.
