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 UX Concept represents a bold crossover future

This is the Lexus UX Concept. You can call it the Ucks, because that's what we're doing. And oh yeah, it's really weird. The UX is a concept in its truest form, from the bizarre wheel/tire combo to the "inside-out" design concept, the latter which reminds of Wonko the Sane from So Long and Thanks for All the Fish. Designed by Lexus' studio in southern France, we aren't even really sure how to describe the design features of the UX. The sharp and angular exterior bleeds in and out of equally strange cabin seamlessly. But more than the body's creases and cuts, it's the general shape of the UX that's most interesting – this is a compact crossover, but it looks more like a jacked-up shooting brake than a typical two-box CUV. The rear doors seemingly bleed into the aggressively raked C-pillar, while the long hood give the UX a more sporting character than most cars in this segment. At the same time, Lexus went out of its way to deemphasize the UX's sporty traits – square, off-road-like wheel arches contrast the strong front fenders that bulge up and above the hood, for example. The fact that designers painted these arches silver to contrast with the lovely amethyst paint gives them an even greater visual weight. Lexus says the overall idea for the silver accents – the wheel arches, mirrors, and roof rails – "represent a form of continuous yet interrupted bone structure." Whatever you say, guys. But the wheels and tires represent the strangest visual detail. The 21-inch wheels actually extend into the tires. Lexus says it used laser carving to cut into the tire sidewalls, and then integrated the wheel spokes into rubber. The visual effect reminds us of those weird airless tires that pop up every few years. The interior, meanwhile, implements Lexus' Kinetic Seat Concept for the first time. Believe it or not, the futuristic seats are the most insignificant part of the cabin. See, UX, in tech circles, is short for user experience. With a name like that, we expect big changes to the driving experience, and that's what Lexus delivers – from the swooping, overlapping dash that creates a real sense of depth from the driver's seat to the three-dimensional effect of the cabin's three displays, the cabin is a fascinating place. Of all the "deconstructed" styling elements Lexus implemented on the UX, we like the design of the dash the most.

Jaguar solution to keyless start could save lives

UPDATED: An earlier version of this story indicated the Jaguar keyless start function was meant as a safety feature, when in fact, it is meant as a convenience one and will not work as described if automatic stop/start is not engaged. Today, The New York Times published an article about more than two dozen deaths related to drivers accidentally leaving their cars running, closing their garages and later succumbing to carbon monoxide that flooded their homes. The reason has been identified as "keyless start" features, or proximity entry and push-button start, where owners don't need to physically handle a key or fob to gain entry into the vehicle or start it. It is the latest, and deadliest, issue raised with this system after those related to security and simple inconvenience (for instance, leaving the car at a valet or car wash with the fob in your pocket). From my personal perspective, The New York Times had a rather harsh "evil carmakers" tone throughout the article. This is not a matter of a known faulty component, as with the GM ignition switch recall. This has as much to do with user error where people leave their car without pressing the "off" button and without noticing the engine is still running. About half of the cars in question are produced by Toyota and Lexus, brands that have offered keyless start longer than most. They are also brands with high rates of elderly owners, who seemingly made up a majority of reported deaths and injuries. One fire department in Florida even started a campaign alerting those in the area of the dangers of leaving your car running when it noticed a correlation between an increase in cars equipped with keyless start and calls related to carbon monoxide poisoning. I see several contributing issues at play, most of which go well beyond this particular issue. First is insufficient training of owners by dealers and/or owners not paying close enough attention during this training. Cars are complicated, but you should at least know how basic functions work. Second, woefully inadequate driver training in this country. Third, and with apologies to the AARP, insufficient testing of elderly drivers and/or insufficiently low standards for elderly drivers. If you don't know you have to shut the car off or cannot hear that an engine is running, perhaps you shouldn't be driving. Fourth, re-examining keyless start systems.
