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.

2016 Lexus RX sharpens up for round four

Go back a couple of decades and no one would have heard of a luxury crossover. Most of the benefits of a luxury sedan and an SUV with few of the drawbacks? Unheard of. Then 1997 rolled around and two vehicles changed the face of the industry forever. One was the Mercedes M-Class. The other was the Lexus RX. And both have seen their successors unveiled at the New York Auto Show this week. The new Mercedes GLE that takes the place of the M-Class, we've already brought you from the floor of the Javitz Center. Now it's time for its Japanese rival. Now entering its fourth generation, the new RX is distinguished from its predecessors with a far more revolutionary design than that which separated the previous three: It's altogether more angular, more recognizable, more... Japanese – from the oversized spindle grille to the sharp taillights and at every pointy point in between. Of course it's not quite as edgy as its kid brother, the NX, but it has to appeal to a more conservative customer base. They'll get to choose once again between the RX 350 with conventional V6 and the RX 450h with its hybrid powertrain, both of which have been upgraded to produce 300 horsepower. The interior has likewise been updates as well, with more space and enhanced equipment. All of which ought to help the RX remain the top seller for Toyota's luxury division. Related Video:
