2015 Lexus NX 300h

With so much hullabaloo being made over the first gasoline turbocharged engine produced by Lexus, it's easy to forget that there's another option for those who'd rather (barely) hear the whirring of electric motors than the high-pitched whizzing of turbos. That's too bad, because we think the NX 300h is one of the more interesting hybrids on the market, due in large part to its innovative all-wheel-drive system and relatively sporty driving dynamics. We spent several hours with the brand-new hybrid crossover from Lexus, and we came away with plenty to talk about.
Driving Notes
Of course, the big thing that differentiates the 300h from the 200t is its drivetrain. In place of the 2.0-liter turbocharged four-cylinder sits a 2.5-liter gasoline engine that runs exclusively on the Atkinson cycle to save fuel, augmented by a pair of electric motors and mated to an electronic continuously variable transmission. Lexus is no stranger to hybrids, buoyed by parent company Toyota's expertise, and the basic setup used by the NX 300h is a well-known quantity shared with the ES 300h.

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.
