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 LF-LC approved for production

On the sidelines of a press drive for the 2014 Lexus IS, the company's vice president of marketing in the US told Ward's Auto that the honchos in Japan have approved the Lexus LF-LC concept for production. He wouldn't offer any other details on how the luxury coupe might be transformed into a vehicle for the buying masses, and that has led to a bag full of speculation.
The show car was hybrid-powered and rear-wheel drive, a beautifully executed stab by Toyota designers in Newport Beach at redefining Lexus, but even with the concept, the point was to keep it "within reach for premium buyers." The report says the odds are on limited production and higher pricing than Lexus' "mainstream products," and other sites have speculated on what kind of powertrain it might end up in showrooms with.
GT Channel posits that the LF-LC will be the inspiration for a coupe in the Lexus LS price bracket with a choice of either the 4.2-liter V8 or the hybrid powertrain from the LS 600h, further speculating it will be called LC 550 and cost more than $100,000. It then says that there would be another coupe created beneath that one to replace the SC 430. Lexus Enthusiast, however, calls those "warmed-over rumors" and says that the marque probably won't deviate from its engine-capacity-naming scheme - labeling a car with a 4.2-liter V8 an LC 550. Nor does it think Lexus will use the letters LC after the company has trademarked "RC" in the US and Australia.

Lexus resurrecting SC name for big, expensive coupe

Lexus is preparing the SC nomenclature for its third act, after the first bombshell SC coupe from 1991 and the second, Desperate Housewives hardtop convertible evolution from 2001. The brand is aiming again for something that makes a deep mark, with rumored specs pointing to a large, heavy, powerful coupe that will square its spindle grille up against the Mercedes SL and BMW 6 Series. It will be built on the frame of the next-generation LS sedan, and Automobile says internal combustion motivation will come in three flavors. The starter will be a juiced-up version of the company's 5.0-liter, naturally aspirated V8, the one that currently makes 467 horsepower in the RC F. Stepping up from there will be some kind of hybrid powertrain good for around 500 horsepower; last year Motor Trend wrote that the hybrid would be based around a V6 ICE with Toyota's coming "multi-hybrid" system. The top step will be a twin-turbo version of the V8 that could exceed 600 hp. Early reports of dimensions have it at 185 inches long, 75 inches wide, and 53 inches tall. It is expected to use the world's first application of a ten-speed automatic transmission. It'll also get the RC F's torque vectoring mechanism for the rear-wheel-drive setup, though Car and Driver says an all-wheel drive option "might be added later." Aluminum and carbon fiber components will help manage weight. Its design will be inspired by the LF-LC concept, and right now its pricing is as murky as its looks. C/D posits an MSRP from $80,000 to $95,000, Automobile figures it will go "past the $100,000 mark," and MT pegs the situation at $150,000. All agree, however, that it will join the retail pipeline as a 2017 model.
