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 debut small hybrid CUV at 2014 Geneva Motor Show

Following rumors that Lexus has been working on a small crossover to slot below the RX (pictured), Automotive News Europe reports that the production-ready CUV will bow at the 2014 Geneva Motor Show next March. Later this year, Lexus will preview this new crossover by way of a concept car at the Tokyo Motor Show in November.
According to the report, this new crossover will be a hybrid, and will ride on the smaller architecture that underpins the Toyota RAV4. Specific details have not been confirmed, but AN states that the entry-level CUV will be powered by the same 2.5-liter gasoline-electric drivetrain found in the Lexus ES 300h. Since Toyota will evidently be taking the time to hybridize the platform, we can't help but assume that it will eventually build a second-gen RAV4 EV.
Either way, with the small luxury CUV segment heating up, Lexus is likely smart to offer a player in this space. Until now, there has not been a Lexus crossover below the RX, and this new model will compete with other new players in the class including the BMW X1 and Audi Q3.

Lexus reveals production RC coupe en route to Tokyo

Feast your eyes, ladies and gentlemen, on the new Lexus RC coupe. With the exception of the six-figure LFA supercar, it's the first stand-alone two-door model to come from Toyota's premium brand since the demise of the SC, and it's coming to the Tokyo Motor Show later this month.
With unmistakably Japanese styling, the Lexus RC is clearly inspired by the LF-CC and LF-LC concepts, and features the brand's signature spindle grille. Anyone who's been inside a contemporary Lexus should feel right at home inside the four-seat cabin, where the Japanese automaker has fitted ambient lighting that glows upwards instead of down, coupled with a new Remote Touch Interface.
Lexus has already announced two versions of the coupe: the conventional RC350 with a 3.5-liter gasoline engine and the RC300h with a 2.5-liter hybrid setup. It's all packed into a form that, for comparison's sake, is slightly larger than the new BMW 4 Series but markedly smaller (in every dimension but height) than a 6 Series.
