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 reveals more photos of its future electric sports car

Lexus previewed its Electrified Sport late last year amongst a gaggle of other EVs the company says is coming by 2030. However, photos of the two-door sports car were in short supply back then. That changes today. Now, you can see the battery electric sports car in all its glory with a number of images from different angles, in a fresh batch released by Lexus. Unfortunately, the new images are not accompanied by new information. This means we’re still dealing with the same set of details Lexus provided a couple of months ago. The EV is predicted to have a 0-60 mph time in the mid-2-second range, and its total range is going to be greater than 430 miles. The latter part of that spec breakdown is reliant on the use of solid-state batteries, so weÂ’ll just have to wait and see if that tech comes to fruition by the time this sports car launches. As for the photos, weÂ’re just as entranced by this Lexus as we were before. ItÂ’s meant to revive “the spirit of the iconic Lexus LFA,” and its two-door coupe body style with the extra-long hood is certainly working in our eyes. We canÂ’t be sure how much of this conceptÂ’s design will reach production, but if the final car looks like this, itÂ’s going to be a stunner. LexusÂ’ recent track record on two-door luxury sports cars has us thinking positively, too — just look at the LC 500 as proof. More details on the car and its timing are likely a long way out at this point, but at least there are some pretty pictures to look at in the meantime.
