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.

Toyota and Lexus show off advanced safety research vehicle [w/video]

While Google and Audi explore the possibilities of autonomous vehicles, Toyota and its Lexus division are studying the intermediate step of vehicles equipped with a deep suite of technology that help drivers make the best decisions. Introduced at this week's Consumer Electronics Show in Las Vegas, the Lexus advanced safety research vehicle is an LS sedan fitted with three high-def color cameras to detect objects up to almost 500 feet away, 360-degree Light Detection and Ranging (LIDAR) lasers that can detect objects up to 220 feet away, three radar units to keep track of other vehicles at intersections, a precision odometer on the rear wheel, GPS that estimates orientation and an accelerometer.
Currently testing at a purpose-built 8.6 acre urban testing ground at the Higashi-Fuji Technical Center in Susono, Japan the Toyota research vehicle is being used to study how to make better drivers, as well as figuring out how to reduce crashes as the industry's journey through passive and active safety systems progresses. In the event of a crash, new rescue systems are also being tested.
Further investment is being put into the Intelligent Transportation System (ITS) that would use shortwave signals to harness information from the car and from other vehicles on the road, as well as roadside infrastructure and even pedestrians. Toyota reasons it could then build a picture of interactions and, for instance, alert the driver to a potential collision at a blind intersection.

Lexus RC media event in Japan canceled over lack of interest

It's a good thing senior editor Seyth Miersma doesn't live in Japan, or he wouldn't have been able to snap a photo like the one you see here, of a fresh-off-the-line Lexus RC F on hand at a first drive for media. That's because Toyota's Japanese arm has outright canceled its RC press launch. Sure, we've heard about events being delayed, but canceled? That's rare. Even worse is the reason: according to Automotive News, the event was nixed due to lack of interest. Wow.
In an email to media, Lexus said the event "has been canceled due to insufficient attendance," according to AN. The News posits that perhaps it would have just been better to hold the event anyway, in an attempt to save face, and that this is another example of the Japanese culture (especially youth) becoming less and less interested in cars. Of course, there's also the thought that local media just didn't want to drive out to Yokohama to drive the RC on a not-so-sexy press launch, which, if you ask us, is an incredibly lame excuse (do your jobs, folks!).
Either way, will this bode well for the Lexus RC's public launch? Will it receive the same lukewarm response when it arrives at Japanese dealers? We'll see.
