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 boots up 2014 IS configurator

Throw away those scraps of paper and pull yourself up to a keyboard, as Lexus has launched the online configurator for its all-new 2014 IS sedan. The base price for the entry-level IS 250 RWD is $36,845 (all listed prices include the $895 delivery fee), delivering a 2.5-liter V6 rated at 204 horsepower that provides enough thrust for a 0-60 sprint in 7.7 seconds. The range-topping IS 350 AWD starts at $42,595, packed with a 3.5-liter V6 rated at 306 horsepower that will deliver 60 mph in just 5.7 seconds.
After choosing an engine and driveline, the configurator will offer eight exterior colors and five interior upholstery shades (some combinations, such as selecting Obsidian over Rioja Red NuLuxe leather, require upgrades such as the F Sport package). Consumers are then offered four different bundled option packages as enhancements. The least expensive is Navigation ($4,670), followed by the aforementioned F Sport ($5,800) and a choice between two luxury packages ($7,195) with light or dark wood trim.
Last to come are the accessories and dealer-installed options such as remote engine start, glass-break sensor, wheel locks and a cargo net. Go crazy with your choices, as we did, and the price will exceed $50,000. Head over to the Lexus IS configurator, and check it out for yourself.

Lexus to display turbocharged LF-NX Concept at Tokyo Motor Show

Concept cars typically have a short lifespan. They debut at a major international auto show, then make the rounds of the lesser local shows, and that's pretty much it. They might be loaned out for test drives or put on display in a museum, but by and large they've had their fifteen minutes of fame by that point. That said, Japan's automakers have found a way to keep these show cars going and keep them in the news. They're modifying them and giving them a fresh lease on life.
That's what Subaru is doing with the Viziv concept for the upcoming Tokyo Motor Show, and what Lexus is doing as well with the LF-NX concept. Having already unveiled the crossover concept at the Frankfurt Motor Show, Lexus is fitting the LF-NX with a new 2.0-liter turbo engine. (But then, as far as we could tell, Lexus never revealed engine specs for the concept in the first place.)
To go with the turbo engine, Lexus has also fitted the concept with a new front splitter, but otherwise it's the same - and even appears to be wearing the same liquid-metal paint, unlike the LF-LC concept that got repainted from red to blue when its limelight was starting to fade.
