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 teases new F Sport engine cover

Lexus has teased a new F Sport model by revealing just the engine cover. It could point to a new performance version of the 2021 Lexus IS, and a potential successor to the dearly departed IS F. The image was obtained by Lexus Enthusiast, which pointed out that the carbon-fiber pattern cover is exactly the same shape as the one found shrouding the 5.0-liter V8 that powers the GS F and RC F. Good for 467 horsepower and 389 lb-ft of torque and a symphonic revving sound, the 2UR-GSE has traditionally been the heart of Lexus's F performance line. The teased cover, however, shows an "F Sport" badge where the GS F and RC F's "F" badge once resided. That implies a car with stiffer sport suspension along with some of the styling of a full-blown F model, but not the full stable of horses under the hood. Recently, Best Car magazine reported that Lexus was about to come out with a trio of F models. We think this engine cover is unlikely to preview an LC F, as the LC 500 is already powered by the 2UR-GSE, and wears a completely different engine cover. Also, an LC F would likely be turbocharged and thus don a different cover altogether. While it's possible that Lexus would drop the more powerful 2UR-GSE into the LS to give it a 73-horsepower bump over its current 394, that would imply an LS F model, not a simple F Sport. And besides, the LS already has an F Sport variant. The Best Car report also indicated that the LS F in the works, if it happens at all — and that's a big "if" — would be propelled by a twin-turbo V8.  That leaves the new IS, which in its most powerful guise has a 3.5-liter V6 generating 311 horses and 280 lb-ft of torque. It's possible that rather the teased engine cover is foreshadowing an IS 500, a conclusion that Lexus Enthusiast also draws, albeit with slightly different reasoning. An IS 500 would be one way for Lexus to squeeze as much use out of its marvelous 2UR-GSE before the V8 goes the way of the dodo, but without having to develop an all-out F model. The original IS F had, among other things, wider body panels, six-pot front brake calipers with cross-drilled rotors, and a Torsen LSD. By not calling an IS F, Lexus could be lowering expectations for enthusiasts of the original who would expect those performance features. Or, if the V8 gods are listening, perhaps Lexus is saving the true F badge for an IS with the rumored twin-turbo powering the LC F. One can hope, right? Related Video:

2022 Lexus IS 500 F Sport First Drive | A charismatic outlier

For 2022, the Lexus IS is getting a V8, the first time since the last IS F was built back in 2014. But instead of an uncompromisingly sporty successor to the IS F, Lexus has created something a little softer and more civilized, and given it a similarly watered-down name: IS 500 F Sport. And in our time with the sedan, it's an apt name, since it's not a real competitor for the M, AMG, RS and Blackwings of the world. But what it is isn't bad, either. It's a characterful sport sedan that makes for an interesting alternative to similarly softer and more civilized choices like the BMW M340i or Audi S4. It is hampered by some familiar Lexus problems, but it has enough to like that the right buyer can happily overlook the shortcomings. Before diving too deep into the driving impressions, let's go over what was done to create the 2022 Lexus IS 500 F Sport. The lynchpin is the 5.0-liter naturally aspirated V8. It's a unique feature for a class full of turbocharged four- and six-cylinder engines. It sends 472 horsepower and 395 pound-feet of torque to the rear through an eight-speed automatic transmission and a standard limited-slip differential. Lexus clocks the 0-60 time at 4.4 seconds, which is on par with the rear-drive M340i. Of course, the BMW has 90 fewer horsepower. It sits on a sport-tuned adaptive suspension and gets bigger brakes with better cooling, but that's about it for mechanical upgrades. It's all wrapped in a body that looks almost exactly like the IS 350 F Sport except for the quad exhaust, exclusive Enkei wheels and the power bulge that raises the hood by 2 inches. It's great for keeping a low profile, but nodding quietly to those in the know that, yes, this is the fast one. The interior also gets leather and faux suede upholstery, a thick F Sport steering wheel and other F-related trimmings. As with every Lexus so equipped, the IS 500's V8 is a true treat that makes up for whatever disadvantages it might have on paper with endless character in person. It's spectacularly smooth and demure most of the time, but when asked, it delivers a raucous intake growl and a just right amount of exhaust noise. And it does so without needing to have the artificial sound enhancer turned on (it's adjustable from nothing to 100% via a scroll wheel on the dash). It's eager to rev and will do so to a little past 7,000 rpm. Peak power lives up there, but it has enough mid-range grunt to keep it entertaining even when you're not making the most of every gear.
