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 pushing upmarket as others move down, LF-LC production hinted [w/video]

Jeff Bracken, Lexus' US group vice president and general manager, knows his company lost its position as America's biggest luxury brand back in 2011, and it's a mantle that his employer probably won't be getting back any time soon. That's because Lexus is electing not to follow the luxury segment's downmarket trend any more than its $32,500 CT 200h hybrid hatchback. "Since we won't be going down below $30,000, it will be very difficult for us to ever regain luxury leadership," Bracken admitted on Autoline After Hours late last week.
Rivals Mercedes-Benz, BMW and Audi all have new low-end entries on sale or in the wings to entice new buyers and fortify their CAFE scores, but Lexus has Toyota and Scion to capture sales underneath its lineup. Instead, Bracken hints that Lexus is going upmarket and higher-performance, fueling ongoing rumors of a LFA successor, or perhaps a new offering based on the lauded 2012 LF-LC coupe concept shown above, a production version of which could also slot in where the unloved SC convertible left off. "We need to begin bringing to market luxury performance... higher performance vehicles. IS-F certainly was the beginning of that, maybe on the lower end," says Bracken.
Later in the online video interview show, Bracken gets even more candid:

An Unlikely Star in the Lexus Stable
Think about Lexus for a second. Odds are your gray matter is busy regurgitating images of the company's middle-aged RX crossover or possibly the midsize ES sedan. As the volume movers for Toyota's luxury fleet, the two are the default ambassadors for everything with an italicized L pinned to the grille, and that's a damned shame. As the 2013 GS450h is so willing to point out, Lexus engineers are busily crafting models that offer drivers more than a safe luxury choice.
As the master of fuel-sipping battery propulsion, Lexus has brought the impressive width of Toyota hybrid engineering to bear on the GS450h. The result is a vehicle that manages to sneak its hybridness by you with buttery acceleration, stone quiet operation and brakes that don't feel like you're trying walk around the house in Velcro socks. The drivetrain doesn't feel the need to beat you over the head with its battery pack or announce to the neighborhood that you're saving the world one whispery mile at a time. Both driver and passengers get to enjoy a luxury car that just so happens to be a hybrid instead of the other way around.
