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.

The Lexus Sriracha IS is the hottest Lexus ever

For this year's Los Angeles auto show, Lexus created its hottest IS ever: the Sriracha IS. And the company did so by putting Sriracha sauce in everything! It's in the paint, the steering wheel, and even in the trunk! Check out the video if you don't believe us. Ok, so Lexus didn't really put Sriracha in everything. In reality, the company partnered with Huy Fong Foods to produce this one-off car, and turned to West Coast Customs to execute it. It features a custom paint job designed to emulate the look of Sriracha sauce, and green accents on the grille, mirrors, brake calipers, and exhaust tips are a call back to the food company's sauce bottles. View 13 Photos Inside, West Coast Customs created some clever and surprisingly subtle changes. The climate controls only show increasing heat levels, and the seat heater buttons are bright red with little flames above the seat icons. The drive selector trades sport mode for "Sriracha" mode. The seats get red and green inserts along with logos stitched into the seat backs. Other parts of the interior have green contrast stitching, too. The steering wheel is a particularly unique piece. West Coast Customs found a liquid that looks similar to sriracha, put it a resin container and shaped it to fit the steering wheel, so now it looks like there's sriracha in the steering wheel. It also has a warning sticker for "hot handling." And lest you think there isn't any real Sriracha anywhere in the car, you'll find 43 bottles of the stuff in the trunk, and the key fob dispenses some as well. As for how Lexus tops this, perhaps they could make a habanero or ghost pepper car. Or maybe they could show us a real IS F successor. We think another V8 Lexus would come across as pretty hot.

Did BMW really win the luxury car sales race?

As anyone who follows our monthly By The Numbers series already knows, the luxury car sales race in the United States was close all of last year as BMW, Lexus and Mercedes-Benz seesawed up and down for sales supremacy. At the end of the year, it was BMW on top of the standings with 346,023 total sales. Or was it? According to data released by Polk, comparing the actual number of vehicles registered between the three top luxury players in the US paints a slightly different picture. Polk's data suggests that only 335,259 BMWs were registered in 2015, compared to 340,392 Lexus models. Why the disparity? It's all a matter of timing. Actual end consumers buy new cars, in almost all cases, from a franchised dealer. BMW delivered 346,023 vehicles in 2015, but only 335,259 of them were registered by their new owners. Presumably, those 11,000 BMWs did (or will) end up registered in the driveways of consumers, but they hadn't before January 1, 2016. Lexus General Manager Jeff Bracken wrote in an email to Automotive News, "Luxury sales leadership as measured by vehicle registrations is important to Lexus as it represents actual consumers engaging directly with our dealers." Of course, it goes without saying that we'll be paying keen attention to the 2016 luxury car sales race as it unfolds. If it's anything like it was in 2015, it'll come down to the wire, and even then may not be entirely clear.
