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 coupe caught in spy shots actually RC, headed for Tokyo reveal?

Lexus may have pulled a fast one on us. The car our spy shooters spotted yesterday may not, in fact, be an IS F Coupe as we indicated. Rather, the car shown above may be a new model, dubbed RC, that will arrive at this year's Tokyo Motor Show.
Following a report from Automotive News, the RC is believed to be a pure coupe, rather than a hardtop convertible. This gels with information provided on the IS sedan's launch, when Lexus spokespeople said the IS Convertible would remain on the current platform. With styling based on the LF-CC from the 2012 Paris show, the new car will share a rear-drive platform with the IS and GS sedans.
Power is expected to come from a 3.5-liter V6 that turns out 306 horsepower. That car will likely wear the RC 350 badge. A hybrid model is expected to follow, but in a twist, it won't be coming to the US. The big news, though, is that the RC will spawn an RC F.

Lexus has big expectations for small NX crossover

One has to wonder why it took so long for Lexus to enter the hotly contested compact premium crossover market. The brand itself projects some 36,000 sales for its brand-new NX, which is set to go on sale in the US in November. Add that potential to the 100,000-plus RX crossovers it sells annually in the States and Lexus looks poised to put some hurt on German rivals like Audi, BMW and Mercedes.
The vast majority of Lexus NX models imported to the States will be powered by a new 2.0-liter turbocharged four-cylinder engine that pumps 235 horsepower and 258 pound-feet of torque to either the front or all four wheels. Just 10 percent or so of NX models will get the 194-horsepower hybrid powertrain wrapped in NX 300h trim. Though not yet rated by the EPA, Lexus projects mileage ratings of 22 city, 28 highway and 24 combined for the turbo and 35/31/33 for front-wheel-drive hybrids (expect a one-mpg combined hit for AWD models with either engine).
In terms of sizing, the Lexus NX is dimensionally very similar to the Audi Q5, which starts at $37,300. Lexus hasn't yet released pricing information for its NX, but promises to be in the same range as its competitors. We note with interest that the larger Lexus RX starts at $40,795 - a little over $3,000 more than the Audi its NX will compete against - and wonder out loud if the Japanese automaker can undercut its German competitors in pricing with the NX. Expect official pricing info from Lexus closer to its on-sale date later this year.
