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.

2018 Lexus LS has a livelier look and new twin-turbo V6

When considering that the Lexus LC 500 made it to production virtually unchanged from concept form, it was reasonable to think that the LS would similarly follow suit. Especially when the LS shares the LC's GA-L platform. Unfortunately, it didn't pan out that way. It is possible to spot cues inspired by the LF-FC concept, such as the lower contour of the windows, the crease in the metal leading up to the rear wheel, and of course the lights and spindle grille. But they're overshadowed by the fact that this LS has a significant amount more girth. View 14 Photos Just because it doesn't live up to the concept doesn't mean it's a bad looking car. It's far more interesting to look at than the dated, upright LS currently on dealer lots. It also sits quite low and the wheels and tires fill the wells nicely, which gives it a road-hugging stance. There are some nifty design details, too, such as the glass that is completely flush with the pillars. View 28 Photos As already mentioned, the new body is wrapped around a stretched version of the LC's platform, and it also uses its 10-speed automatic. Surprisingly, though, the LS doesn't use the LC's powertrain. Under the hood is a completely new twin-turbocharged 3.5-liter V6 that pumps out 415 horsepower and 442 lb-ft of torque. That puts it down on power, but ahead in torque compared with the LC's V8. It's also significantly more than the previous LS' V8, and Lexus predicts it will be capable of a 0-60 mph time of 4.5 seconds with rear-wheel drive. A Lexus PR representative also said the LS is only being released with the V6. We doubt it would be hard to drop one in later though if Lexus saw demand. Inside, the LS is more interesting than the outside would suggest. The dash is clearly inspired by the LC 500, utilizing a similar gauge pod with traction control and drive mode selectors protruding from each side. The dash is also dominated by a wide, dark section that houses the 12.3-inch infotainment display. Just below that, is an attractive strip of slats that follow the contours of the dash and house the air vents. Back seat passengers also will have a pleasant environment thanks to the fact that the LS will only be available in a long wheelbase form, so leg room will never be in short supply. They also will have access to available reclining seats, ottoman, and Shiatsu massage functionality. According to a spokesman, the Japanese-style of massage function is a first for the LS.

10 automakers sued over keyless ignitions

Keyless ignition has rapidly proliferated throughout the auto industry to become a fairly normal feature on new cars. It's supposed to offer the convenience of keeping the fob in your pocket and just pressing a button to drive away. However, ten major automakers are now being sued in US District Court over claims that the system is dangerous, Reuters reports. The suit alleges that people are forgetting to shut off the engine, and the lack of an idle timer is the cause for 13 deaths by carbon monoxide poisoning and multiple injuries. The suit currently includes 28 plaintiffs, according to Reuters, but the lawyers are asking for class-action status to potentially add many more. The case goes after a major swath of the industry, including BMW, Daimler, FCA, Ford, General Motors, Honda, Hyundai, Nissan, Toyota, and Volkswagen, plus their related brands like Acura, Infiniti, Mini, and Lexus. In all, over five million vehicles are affected. The assertion here is that people walk away from their vehicle without shutting it off because they believe the engine shuts off automatically. If parked in a garage, carbon monoxide can build up, leading to poisoning. The lawyers claim automakers know this is a problem and also cite 27 complaints to the National Highway Traffic Safety Administration about the issue, according to Reuters. The plaintiffs are asking for an automatic shut-off and damages from the companies. These concerns have come up before, though. Toyota previously faced a lawsuit over a carbon monoxide death after a woman accidentally left her Lexus running. Also earlier this year, GM recalled 64,186 examples of the 2011-2013 Chevrolet Volt because owners weren't shutting them off. The problem resulted in two injuries, and the company released a software update to limit the idling time.
