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 LF-FC concept is a preview of the next LS [w/video]

As far as flagship luxury sedans go, the Lexus LS is one of the oldest on the market. But the upscale Japanese automaker is out to fix that in short order. And to give us a taste of what's to come, it's presenting the concept you see here at the Tokyo Motor Show today. Called the LF-FC, the show car clearly points the way forward for the next-generation LS. The design adopts the latest take on the brand's "L-finesse" styling language, with a large, spindle-shaped front grille leading to sharp creases cutting their way across the entire surface. Lexus refers to the roofline as approaching that of a four-door coupe, though it clearly places more of an emphasis on rear-seat space. Power comes from a conceptual hydrogen fuel cell whose components have been scattered throughout the vehicle to optimize weight distribution. The fuel cell drives the rear wheels and sends power to hub motors in the front wheels as well for all-wheel-drive capability. Those 21-inch rims are made of carbon fiber, with aluminum spokes, to minimize unsprung weight. Naturally, Lexus has equipped the concept with all the latest electronic aids to track the flow of traffic and even drive autonomously through it. Of course a vehicle like this is designed around the driver and occupants. The white and brown interior space features four individual bucket seats, because really, who wants to dream of riding in the middle? Interior appointments look suitably tasteful, all done in satin-finish wood and metal with white and brown leather, and would look at home on the next generation of first-class aircraft cabins. Lexus has equipped the concept with gesture control that incorporates a floating holographic image to show users where to place their hands to operate the audio and ventilation systems touchlessly. In typical concept style, the LF-FC sits wider and squatter than the production sedans at which it takes aim. More telling, however, is the overall length: at 208.7 inches, it's a few thumbs longer than even the extended version of the current Lexus LS, and a touch longer than the current long-wheelbase Mercedes S-Class, Audi A8, BMW 7 Series, Jaguar XJ, and Maserati Quattroporte. We're looking forward to seeing the production version in the form of the next LS in due course to see how it measures up against the competition, and not just in terms of size.

Luxury car brands scrambling to avoid a blue Christmas

DETROIT — When financial markets surge to new records, sales of luxury cars usually rise, too. Instead, October U.S. auto sales reports on Wednesday showed that a collapse in sales of luxury sedans is accelerating. Consumers have gradually shifted over to luxury sport utility vehicles from sedans in the past decade, but the trend — which has occurred in both the non-luxury and luxury sedan segments of the auto market — was particularly pronounced in October. Sales of Daimler AG's Mercedes-Benz S-Class, long a global benchmark for large, premium sedans, plunged 49 percent in October, and are down 24.8 percent for the year to date. General Motors' Cadillac brand said it sold just 779 of its CTS sedans in October. Demand for that car, designed to compete with German luxury sedans, is down nearly 33 percent for the year. "There's still a significant portion of the market that wants a car, but I'm sure there were people who preferred a horse to a car at one point." Cadillac's best-selling model this year is the XT5 compact SUV, which has more than doubled sales from a year ago. The shift within the luxury vehicle market away from sedans toward SUVs of all sizes is forcing some of the most prestigious brands to scramble to add SUV models to their lineups or boost SUV production to meet demand. "In the short term, there will be pressure to add (consumer) incentives, cut production or both," said Cox Automotive analyst Michelle Krebs. "And we just don't see an end in sight to this trend." The Dow Jones Industrial Average has been trading at all-time highs, usually a good sign for luxury sedans, but as major automakers reported new U.S. vehicle sales for October on Wednesday, sales for passenger cars continued their slide while luxury SUV and crossover sales rose again. According to Kelley Blue Book data, in 2007 luxury sedans made up 7.6 percent of U.S. new vehicle sales, while luxury SUVs made up 4.2 percent. Through September this year, luxury SUVs made up just over 7 percent of the market, compared with 4.9 percent for luxury sedans. In the short term, luxury brands could use holiday season sales promotions to clear slow-selling sedans off dealer lots, analysts said. Toyota's Lexus brand said on Wednesday it will launch its "December to Remember" year-end sales promotion for the 18th straight year.
