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 reveals LF-NX crossover concept for Frankfurt

Compact luxury crossovers are becoming big business for upscale automakers. Mercedes is slotting the new GLA beneath the GLK, BMW has the X1 below the X3, Audi has downsized from the Q5 to the Q3, and Lexus is keen to get in on the game. And to that end, Toyota's luxury division is coming to the Frankfurt Motor Show this year with the concept crossover you see here.
Previewed a couple of weeks ago with an enigmatic teaser, the LF-NX concept, in the company's own words, "explores the potential for a compact crossover within the Lexus model range." The latest adaptation of the "L-finesse" design language could be the sharpest and most stylistically Japanese we've seen yet, with the sharp creases of the signature spindle grille repeated all around for a razor-sharp look. Lexus only released one shot of the cabin, but it looks as sharp as the exterior and, while clearly stylized, looks essentially more production-ready than most show cars.
Lexus hasn't revealed much about the powertrain, saying only that it incorporates "a new variant of the Lexus Hybrid Drive system tuned for SUV performance." Whether it actually has an engine that Lexus will detail at the show remains to be seen, but you can delve into the press release below for more and scope out the five images released thus far in the gallery above for a closer look.

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.
