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.

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.

Toyota shows a smoother autonomous Lexus for CES

Toyota is bringing a new research vehicle to CES. The TRI-P4 autonomous driving test vehicle, based on the Lexus LS500h, is a major step ahead, according to Toyota, as it has improved computing power and additional cameras for better reaction times. Earlier test mules have also used the LS as a basis, and the shift to the new, fifth generation LS brings chassis and steering-control benefits, so the vehicle's movements are smoother in automated mode. The camera tech has also been better integrated into the vehicle design, courtesy of CALTY in Ann Arbor, Michigan. Development has been swift, as the TRI's P2.1 car was unveiled in 2017. The P4 car will be used for Toyota Research Institute's Guardian and Chauffeur mode development. The two tiers differ somewhat, as TRI's Ryan Eustice explains: "Our Chauffeur development is focused on full autonomy, where the human is essentially removed from the driving equation, either completely in all environments, or within a restricted driving domain. Guardian, on the other hand, is being designed to amplify human performance behind the wheel, not replace it. The introduction of the new P4 platform will help us accelerate the development of both tracks when it joins our fleet this spring." The vehicle's situational awareness is boosted by two extra cameras facing on the sides, and a new imaging sensor both forward and rearward. Toyota says the P4's lidar setup is a carryover from the previous platform, but that its machine learning is much improved by its more powerful computer setup. The electricity required by the P4's computing power also comes from the hybrid battery, and as the computer "brain" is now housed vertically against the rear seat's backing, actual trunk space has been freed. More LS500hs will begin to be modified into TRI-P4 vehicles during spring 2019. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
