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.

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.

Lexus LS sedan will be quieter, more comfortable and smarter

Lexus made numerous updates to the LS in a bid to turn it into an even more comfortable cruiser. Unveiled online, the redesigned model gains a quieter cabin, new driving aids, and a handful of minor styling tweaks. Engineers turned their attention to parts of the fifth-generation LS that a majority of owners never think about in order to achieve a ride that's markedly quieter and smoother. They notably fitted a new solenoid to the adaptive suspension that reduces damping force, redesigned the motor mounts to prevent mechanical vibrations from entering the cabin, and changed the stiffness of the run-flat tires as well as the rigidity of the stabilizer bars. These changes come together to cement the sedan's positioning as the cushiest model in its category. Deeper stitch points and seat pads made with low-resilience urethane further enhance comfort, according to Lexus, but the biggest upgrades found inside are technology-related. The LS receives a digital rear-view mirror as well as a 12.3-inch touchscreen compatible with Android Auto and Apple CarPlay. Users can also control the display screen and audio functions using their phone once they've paired it to the infotainment system. LS buyers in select markets will be able to order the company's Teammate technology. It's a semi-automated suite of driving aids that bundles lane-keeping assist and adaptive cruise control while allowing the car to change lanes and pass slower vehicles. It does not turn the LS into an autonomous car; it merely helps motorists when driving becomes tedious. The system can only be used when the right conditions are met, and Lexus hasn't announced plans to offer it in the United States. The latest generation of park assist technology is available, too. The visual changes are relatively subtle. Up front, stylists redesigned the lights and gave the bumper a new look. Out back, eagle-eyed car spotters will notice the lights and the lower bumper have been slightly revised. It's the same story inside, where the most noteworthy change is the addition of the aforementioned touchscreen. Lexus expanded the color palette with a shade of silver named Gin-ei Luster that stands out with a smooth, mirror-like finish.
