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.

Jaguar F-Pace V6 reminds us why we love supercharged engines

There are many things we like about our 2018 Jaguar F-Pace long-term car, as well as some things we don't care for, but easily one of the best things about it is the engine. Under the hood is the 380-horsepower supercharged V6 that Jaguar offers on other models. That amount of power would be fun in just about any car with any engine, but there are specific reasons why this particular engine is special, and it's because of that supercharger. Supercharged engines have a very different character than increasingly common turbo engines. One of the most noticeable differences being engine response. Unlike turbo engines, the F-Pace's V6 feels hardwired to your foot. Every extra millimeter of pedal travel yields a slightly greater amount of tug. And the tug is felt immediately. Even the best turbo engines have a hard time recreating this response. The power band is very linear, as well, so you know exactly what you're getting every time you hit the gas. The engine is wonderfully torquey, too. Because the Jaguar's engine uses a classic Roots-type blower, there's a major improvement in low-end torque. This means that our F-Pace has loads of grunt for punting around at low-rpm and can seriously move when tromping on the gas. And because of the near-instant throttle response and linear power band, it doesn't slam you in the back unexpectedly like some turbo engines do. Despite how great these supercharged engines are to experience, we're concerned that supercharged engines like this may disappear in all but ultra-limited production, high-performance cars such as the Chevy Corvette Z06 and Cadillac CTS-V. The reason being that car companies have to keep making cars more fuel efficient and lower emitting. Putting a supercharger on an engine is adding a handicap, since it takes engine power to spin the belt-driven supercharger. And when a turbo, which uses wasted energy from exhaust gas to spin the compressor and built boost, can effectively do the same thing, it's hard to make a case for a supercharger. We won't give up hope completely, though. Mazda is using superchargers on its spark-assisted compression ignition gasoline engines. And while we're not sure how powerful and sporty those will be, Mazda has said that it's going with superchargers for exactly the reasons we like the Jaguar engine: smooth power and fast throttle response.

Jaguar redesigned the F-Type for 2021, and you can win one here

See official rules on Omaze. Before it was redesigned for the 2021 model year, the Jaguar F-Type was one of the best-looking vehicles on the market. The same can be said for the updated version. What also hasn’t changed is the fact that, while it looks great, it sounds even better. Thanks to a supercharged V8 that makes 575 horsepower, the growl of the F-Type can be heard long before you see it coming. Oh, itÂ’ll turn heads. ItÂ’s also quite a bit of fun to drive too. And Omaze is giving one away.  Win a 2021 Jaguar F-Type R Coupe - Enter at Omaze HereÂ’s what we thought of the F-Type when we first drove it last summer: “Being behind the wheel of the V8-powered F-Type R also remains an absolute hoot. You sit low in the cockpit, looking out over the long hood — we couldnÂ’t see the end of it without raising the seat up a smidge. The round steering wheel is large for a sports car, and while the leather is supple and grippy, it was tough to find a position where our hands were comfortable and our fingers could reach the clicky metal paddle shifters. Two seat types are available on F-Type models, but the more aggressive “Performance” seats come standard on the R. TheyÂ’re plenty bolstered, but wide enough to not be restricting on longer journeys. “The supercharged V8 fires up with a loud snarl, but a new Quiet Start mode can tone it down by closing the valves in the exhaust at startup. Your next-door neighbors will appreciate this feature, as the F-Type R is one of the loudest vehicles with a factory exhaust weÂ’ve ever tested. The engine and exhaust dominate the experience of the car from start to finish. Volume levels range from extremely loud to how the hell is this legal?  “Jaguar claims 60 mph comes in just 3.5 seconds, so acceleration within the speed limits is short-lived. This engineÂ’s nature, the way it makes power, is the most alluring part of the acceleration. You donÂ’t have to wait that split second for a couple turbos to spin up. The power is simply here, and thereÂ’s zero disconnect between your right foot and the Jag bounding forward. DonÂ’t shift before max horsepower comes on at 6,500 rpm, either, as the feeling of forward thrust just gets stronger the more you wind it out.
