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 files to copyright LC 500 nameplates [UPDATE]

UPDATE: Reached for comment, Lexus told Autoblog that it "cannot offer comment on the potential naming of a production version of the LF-LC concept" and pointed out that automakers trademark nameplates as a matter of course. Some automakers already slap a production-ready name on their concepts, but not Lexus. The Japanese automaker typically labels its show cars with the letters LF-XX. So when we heard that Toyota had green-lit the LF-LC concept for production, we naturally started wondering what name the production version would carry. But if the latest intel is any indication, we can stop wondering. According to Lexus Enthusiast, the automaker has filed to trademark the names LC 500 and LC 500h in a variety of markets – including the United States, Canada and Australia. The application tells us a number of things: first of all, that the LF-LC will retain that second set of letters along the road to production (like the NX but unlike other recent Lexus concepts). And secondly, it indicates what engines we can expect to find under the hood. The 500 designation would seem to suggest that the base version of Lexus' upcoming halo sports car will pack the 5.0-liter V8 from the RC F. The bigger question mark is over the hybrid version. Current gasoline-electric models in the company's lineup include the RX 450h (based on a 3.5-liter V6) and the LS 600h (with a 5.0-liter V8). For the LC 500h, Lexus could be planning a more potent electric motor to mate to the 3.5L V6, or planning a new powertrain altogether.

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.
