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 considering V8 Supercars racing program

Just a few years ago, Holden and Ford were the only manufacturers competing in Australia's V8 Supercars series. But those days were left long ago in a cloud of smoke on the track, and are only disappearing even further in the rearview mirror as the latest intel suggests Lexus could be ready to enter the series as well. Speaking with CarAdvice.com.au at the local launch of the RC coupe, Lexus Australia chief Sean Hanley revealed that his office approached the race organizers to hold "very high-level discussions" about the Japanese luxury brand entering the series. The development is reportedly spurred by the warm reception the RC has enjoyed so far Down Under, and by an expected impending shift in the rules of the V8 Supercars championship. The series has been rumored to be shifting away from strictly eight-cylinder sedans to include coupes and other engine types – a move that would open the door to more manufacturers to participate, including Lexus with the RC F. Currently the field is made up of Holden Commodores, Ford Falcons, Nissan Altimas, Volvo S60s and privately-entered Mercedes E63 AMGs. Nissan, Volvo and Mercedes only joined in the past couple of seasons following the last round of rules changes. The series received "international" status from the FIA in 2011and in the past few seasons has held races in locations as far flung as Abu Dhabi and Texas to its principally Australia-based calendar. Lexus, for its part, has competed in Grand-Am, Germany's Nurburgring-based VLN series and Japan's Super GT series, but unlike parent company Toyota, has yet to embark upon a top-level racing program in Formula One, the World Rally Championship or at Le Mans.

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.
