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 to display turbocharged LF-NX Concept at Tokyo Motor Show

Concept cars typically have a short lifespan. They debut at a major international auto show, then make the rounds of the lesser local shows, and that's pretty much it. They might be loaned out for test drives or put on display in a museum, but by and large they've had their fifteen minutes of fame by that point. That said, Japan's automakers have found a way to keep these show cars going and keep them in the news. They're modifying them and giving them a fresh lease on life.
That's what Subaru is doing with the Viziv concept for the upcoming Tokyo Motor Show, and what Lexus is doing as well with the LF-NX concept. Having already unveiled the crossover concept at the Frankfurt Motor Show, Lexus is fitting the LF-NX with a new 2.0-liter turbo engine. (But then, as far as we could tell, Lexus never revealed engine specs for the concept in the first place.)
To go with the turbo engine, Lexus has also fitted the concept with a new front splitter, but otherwise it's the same - and even appears to be wearing the same liquid-metal paint, unlike the LF-LC concept that got repainted from red to blue when its limelight was starting to fade.

2015 Lexus NX starts at $34,480*

Lexus has announced pricing for the 2015 NX crossover lineup, which goes on sale next month.
The NX 200t starts at $34,480, and the all-wheel-drive model adds a $1,400 premium to lift the sticker to $35,880 (*destination charges of $925 are not included in the prices). The 200t uses a 2.0-liter four-cylinder engine making 235 horsepower, and it's Lexus' first-ever gasoline-fed turbo.
The hybrid version, the 300h, starts at $39,720, and all-wheel drive tacks on $1,590 for a price of $41,310. The hybrid teams a 2.5-liter four-cylinder with an electric motor to generate 194 hp. Though power dips, Lexus anticipates this version will get a combined 33 miles per gallon with front-wheel drive when the EPA ratings are announced - a considerable leap when compared with the combined 24-mpg estimate for the turbo model.
