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 LF-NX Concept takes aim at the small crossover herd [w/video]

Lexus is drawing crowds with its sharply styled LF-NX Concept, a car that previews a competitor for the likes of the BMW X1, Mercedes-Benz GLK (also debuting at Frankfurt) and Audi Q3. We previewed the LF-NX last week, but we've since gotten a bit of in-person time with the compact crossover on the Frankfurt show floor.
There's a lot of show-car tinsel here, but the makings of a production model are fairly visible. That trademark Lexus face, with the separate headlight and running light arrays and an even more extreme version of the "spindle" grille, is present and accounted for. The styling is sliced and carved, like the Lexus IS, although it's difficult to tell if the production model will be quite so extreme in its looks. We'll bet yes.
Take a look above for the full set of live images from Frankfurt, then scroll down for video and some of the stock images from the original, online unveiling. Finally, click over for our complete coverage of the LF-NX from its debut, last week.

Vice chronicles Okinawa's illegal street racing scene

We all know that street racing is dangerous, and that motorsports are best left on the track or drag strip. However, that doesn't mean that there still isn't some outlaw allure among enthusiasts of racing on public roads. In this video, Vice Japan profiles Eikichi Nagayoshi of Japan's island of Okinawa. He is a used car dealer by day and an illegal racer by night.
Nagayoshi has a deep love for his highly customized Toyota Aristo (better known to us as a first-generation Lexus GS) that he claims produces over 1,000 horsepower and has hit 205 miles per hour. He races his car both on drag strips and in drifting competitions, but says that he often has to ship the car to mainland Japan to compete. In the absence of those opportunities, he sometimes gathers friends and takes the racing to the public roads. While we're not down with street racing, this Vice video is an intriguing personality piece, as well as a look into Japan's fabled underground racing scene.
