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 settles first wrongful death suit related to unintended acceleration

Toyota's sales seem to have rebounded from the unintended acceleration issues from 2009 and 2010, but the automaker is far from done dealing with this situation. Following a settlement worth up to $1.4 billion for economic loss to affected vehicle owners, Toyota has settled rather than going to trial in a wrongful death lawsuit stemming from an accident in Utah in 2010 that left two passengers dead. This isn't the first case in which Toyota has settled, but it was the first among a consolidated group of cases being held in Santa Ana, CA.
According to The Detroit News, this case was scheduled to take place next month, and it was for a November 2010 incident in which Paul Van Alfen and Charlene James Lloyd were killed in a Camry when, based on findings by the Utah Highway Patrol, the accelerator got stuck causing the car to speed out of control and hit a wall; the terms of the settlement were not announced.
The article says that while Toyota will settle on some cases, it doesn't plan on settling on all of them as it still wants to be able to "defend [its] product at trial." This will probably be the case in suits claiming that software for the drive-by-wire accelerator was the cause of an accident in a Toyota or Lexus vehicle. The question of whether or not the electronic accelerator played any role in this problem has been a hot-button topic since the beginning. Toyota has issued recalls in the past to attempt to prevent unintended acceleration caused by trapped floor mats and faulty accelerator pedals, but it also says driver error was to blame in some instances.

Toyota announces two recalls affecting 1M Corolla, Matrix and Lexus IS models

The recall bug strikes Toyota again. The automaker has issued a voluntary recall of three models that, in total, represent more than one million units. Around 752,000 2003-2004 Toyota Corolla and Matrix models are being recalled for airbag concerns, while a windshield wiper issue is causing the recall for close to 270,000 Lexus IS sedans from the 2006-2012 model years.
Completely unrelated to the small airbag-related recall issued earlier in the week, the Corolla and Matrix recall is caused by a faulty airbag control module that could potentially short circuit, which could lead to the front airbags or seat belt pretensioners deploying. The Lexus recall is due to a wiper arm nut that wasn't tightened properly, which can cause the wipers to not work when trying to clear heavy buildup such as snow.
