8 things you should know about the Lexus LC 500h powertrain

Lexus unveiled the LC 500h today in The Netherlands, and I got to take a look inside its new hybrid system. On one hand it seems like a box of magic – it combines two seemingly incompatible transmission types into one package. But that's also the ingenious simplicity of the thing. We don't have all of the details on how it all works yet, but here's a rundown of the high points.Efficient business in front, low-key party in the back. What makes it all work is the mullet of transmissions. For the new hybrid transmission, Lexus used the Toyota Hybrid Synergy Drive/Lexus Hybrid System – which consists of an e-CVT with a planetary gearset and two electric motors (one for charging the battery, the other for motivation and regen) – and grafted a conventional four-speed automatic onto the back. The two units actually coexist in one package, with the e-CVT making things efficient and the automatic expanding the capabilities. So at the low end, the system can deliver more torque, and the engine can also run at lower rpm on the highway. It's all thanks to those fixed gear ratios, and it's surprisingly simple.Except it's not that simple. This is where the virtual gear ratios come in. Like current Lexus hybrids, the system has ratios it can call up with the e-CVT. In this case, there are six virtual ratios to complement the four real physical ratios, for a total of 10 "gears" at the transmission's disposal. (Not coincidentally, the V8 LC 500 coupe has a 10-speed automatic.) One of the four fixed gears is always engaged when the car is moving, so the 10 ratios come about from combinations of what the e-CVT in front and the automatic in the back are doing. In other words, all 10 ratios are variations on the four fixed gear ratios, which means that all 10 gears could be considered virtual.It won't use all the gears all the time. In Eco mode, the car will start off on electric power and skip the first couple of "gears." When it's set to Sport or Sport +, the engine will be engaged from a stop and the transmission will select the lowest ratio. The sportier modes will also ignore the top couple of gear ratios.It can drive faster with the engine off. In a Lexus GS 450h with the Lexus Hybrid System, for example, at speeds above 62 mph or so the engine has to start up. This is because something needs to take up some slack from the battery-charging motor-generator or else it will start spinning too quickly.

Lexus LC 500h | Autoblog's 2018 Technology of the Year winner

Each year, we here at Autoblog review and test hundreds of cars from dozens of automakers, but only a few show the kind of technological advancement (whether that's infotainment, active safety features, advanced engine or transmission designs, or novel suspension) required to compete in the Technology of the Year award process. We award an automaker for bringing to the market features, components or an entire vehicle that we feel pushes the industry forward and sets the stage for things to come. For 2018, the Autoblog Technology of the Year award goes to the Lexus LC 500h and its Multi-Stage Hybrid System. For years, hybrids have sacrificed engaging dynamics in favor of improved efficiency. A few high-end models bucked that trend, but nothing truly mainstream felt quite right. Lexus' Multi-Stage Hybrid System is different, marrying an e-CVT that has six virtual gears to a conventional four-speed automatic, resulting in 10 effective ratios. It's as complicated as it sounds, though in practice the difference between it and a standard automatic is nigh imperceptible. You get the benefits of a hybrid — fuel efficiency, part-time all-electric driving — without sacrificing driver enjoyment, all packaged inside a stunning, fun-to-drive grand tourer. We feel the new hybrid system really gives the LC 500h a leg up on the competition, particularly because it pairs long-distance comfort, high performance, and efficiency in a way we feel will really resonate with consumers (and competing automakers, too). Our editors were impressed by just how well the LC 500h passed off duties between the internal-combustion engine and the electric motors, the only real tell that it was in EV mode being the tachometer needle resting at zero. And the regular Lexus LC 500 is also a wonderful car. It's also a step forward for Lexus as a whole. For years, the Japanese automaker was known for solid luxury vehicles that were sedate to a fault. The LFA was a worthy halo car, but it was also basically unattainable to an average well-off buyer. The F performance vehicles (IS F, GS F, and RC F) gave a much-needed kick to the brand but were a bit rowdy and rough around the edges. The LC 500h strikes a more perfect balance that feels truer to Lexus' brand values: It's quiet without being boring, and exciting without offending. It's also green without punishing the driver for it. Lexus paid great care to get the balance of this car right.

Lexus spotted testing LF-LC coupe for production

Lexus has been preparing a production version of the LF-LC concept for some time now. The coupe would fill at least part of the void left by the culmination of the LFA's production run, albeit at a much lower market position. And judging by these latest spy shots, it looks like it's finally getting down to it. Spotted undergoing testing in Germany around the neighborhood of the Nurburgring, this camouflaged prototype provides us with our first glimpse at what the production LC will look like. It's still hard to tell with all those swirls encircling its bodywork, but the production version looks poised to adopt a form derived from the concept first seen at the Detroit Auto Show way back in 2012. Just don't expect the details to be quite as extreme as those on the show car. It may also be too early to determine what's under the hood, but the signs point towards implementation of the 5.0-liter V8 from the RC-F. A twin-turbo version of the same engine in the form of an LC-F could follow with even more power, while a hybrid V6 is also said to be in the cards. If you're having trouble imaging what it would go up against in the marketplace, though, our spy photographers on the ground inform us that Lexus has been benchmarking this prototype against a BMW 6 Series, Porsche 911, and Maserati GranTurismo. That'd put it in good company, and we're looking forward to seeing how it turns out. Related Video:
