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.

Judge halts Toyota unintended acceleration cases, triggers time for settlement negotiations

So far, the lawsuits brought forth against Toyota for unintended acceleration have gone both ways: the automaker was found not at fault in a 2009 California crash and liable for a 2007 crash in Oklahoma. Both cases involved a Camry and resulted in fatalities. With a big chunk of these UA cases (around 200) set to his the docket of US District Judge James V. Selna in Santa Ana, California, Bloomberg is reporting that the judge has halted the lawsuits until March after Toyota and its lawyers have had extra time to try and settle the cases.
According to the article, Toyota is looking to take care of the cases out of court with an "intensive settlement process." Having already paid out $1.6 billion in "economic loss" suits, this latest settlement process is aimed at the wrongful death and personal injury cases allegedly associated with unintended acceleration. A hearing for the settlements will be held on January 14 with conferences on the matter commencing in February. There is no word as to when lawsuits may start back up if settlements can't be agreed upon.

Recharge Wrap-up: Tesla breaks dyno on video, Lexus trademarks 'LS 500h'

A video shows a Tesla Model S P85D breaking a dyno during a test. Starting at a slow roll, the instant torque under full power snapped a belt on the dynamometer. Before it broke, the dyno measured over 700 pound-feet of torque from the all-wheel-drive Tesla. A previous dyno run saw the car reach its 155-mph top speed and a peak 435 horsepower. See the video above, and read more at DragTimes. Lexus has filed a trademark for "LS 500h" in Europe. This calls for some speculation as to what this means for an upcoming model. It could be that Lexus plans to release the LS with a new powertrain, perhaps a 4.0-liter engine with a hybrid system. Maybe it will use the 3.5-liter V-6 with a more powerful hybrid system. The LS 600h could simply be getting a new name. Or, we might not see the LS 500h badge used at all in the near future. Note that Lexus trademarked LC 500 and LC 500h in Canada last year, and we've seen no such cars yet. Read more at Hybrid Cars. Ethanol producers have strong words in response to the American Petroleum Institute's claims for demand for ethanol-free gasoline. The API and National Marine Manufacturers Association have urged the EPA to consider marine and small engine demand for E0 gasoline when setting Renewable Fuel Standard volume requirements. Big Oil is using a "false narrative to discourage the use of a cleaner, less expensive, homegrown renewable fuel," according to Growth Energy CEO Tom Buis. Buis says ethanol doesn't cause problems in marine and small engines, a statement backed by the Outdoor Power Equipment Institute. "What probably does concern boaters is the amount of time they spend dry docked as a result of oil spills, like the one that dumped 21,000 gallons of oil along four miles of coastline in Santa Barbara, California," says Buis.
