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.

Best places to get your car maintained and repaired

In this era of rampant inflation and high interest rates, the challenges of acquiring a car or SUV have been well documented. And so it has never been more important to protect that expensive investment by maintaining it. In recent months, Autoblog has shared Consumer Reports' evaluation of the least and most expensive car brands to keep running, as well as tips to prolong a car’s useful life. Especially since the pandemic, a number of factors have impacted these costs: more complex vehicles, new materials and manufacturing methods, a shortage of qualified technicians and replacement parts. Since 2022, repairs costs have jumped each year by about 10 percent. This month, Consumer Reports is offering a useful primer on keeping your ride in great shape, suggesting what might be the best options for searching out a repair shop, depending, as CR says, “on your car and your situation.” Author Ben Preston identifies three basic types of repair facilities: dealership service departments, independently owned repair shops, and chain repair shops. Building up trust with a specific shop and feeling comfortable going there is important. Preston quotes John Ibbotson, chief mechanic at Consumer ReportsÂ’ Auto Test Center: "You might be able to save a few bucks by going to whichever shop offers the cheapest prices, but if you want consistent, reliable service, itÂ’s best to find a repair shop you trust and stick with it,” Ibbotson says. The story goes on to evaluate each type of service facility. HereÂ’s a breakdown of CRÂ’s findings: Dealerships These work well for owners of newer cars, especially for covered warranty work. But the disadvantage is the high labor rates common to dealer service. Satisfaction ratings for dealer service departments range from very good (Acura, Lexus, Mazda, and Volvo) to not-so-good (Jeep and Kia). Dealers are best for: Fixing infotainment system glitches: "If the screen in the center of your dash has a habit of freezing up, or the touchscreen-activated climate controls arenÂ’t working, the dealership is the most likely place to find someone with the know-how to fix problems that maybe only a factory-authorized technician can access," Ibbotson says. Safety system recalibration: "Anything from a crack in your windshield to a minor fender dent can upset the calibration of the sensors that make features like automatic emergency braking and adaptive cruise control work," says Ibbotson.

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.
