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 US execs want the LF-1 Limitless concept or something like it

Many years ago, Mercedes-Benz counted many blue moons debating about and then hinting at a full-sized SUV, before the GLS-Class arrived in 2007 (known then as the GL-Class). After that, Audi and BMW each grabbed a gilded handle on The Waffler's Cup, equivocating for years about a Q8 and an X7, respectively; both of those luxurious load-haulers are expected in showrooms soon. Having seen the Lexus LF-1 Limitless Concept at the Detroit Auto Show, we wonder if Lexus intends to hoe that same row - dodging years of questions about a production version of the LF-1 Limitless before finally committing. Lexus US general manager Jeff Bracken hopes that's not the case. His address to the unveil audience at the NAIAS included the appeal, "We have to build this vehicle," aimed at his boss, Lexus global chief Yoshihiro Sawa. Bracken stoked the flames of his own desire after the reveal, telling journalists, "We couldn't be happier if we turned this into a production vehicle," and, "We clearly have a gap at the high-end premium cross-utility segment." We're certain plenty of his colleagues share the sentiments, and why wouldn't they? A Lexus LS-based family functionary begs the question, "Why isn't this already a thing?" The LF-1 Limitless does fierce, futuristic service to its Ghost in the Shell design philosophy of "molten katana," and Lexus needs a proper three-row crossover. Not the three-row RX, nor the opulent, cretaceous GX and LX SUVs, but a unibody crossover to challenge the aforementioned German rivals. If Lexus really does "want to be the brand which is emotionally connected with the customer," it would do well to begin its courtship with this rose-copper gem.
