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.

Evo pits Jaguar XKR-S vs. Mercedes SL63 AMG in heavyweight droptop fight

We recently received the sad news that the Jaguar XK is ceasing production by the end of the year, but what better way to bid it farewell than with some big, smoky powerslides? The retirement of the sporty GT isn't actually the topic of the latest video from Evo - it's on hand to compete against the Mercedes-Benz SL63 AMG to see which is faster around a track. Still, we can think of it as a wonderful sendoff for the Jag.
Both convertible grand tourers get their laps around the course, and they couldn't be more different. Driver Jethro Bovingdon gets some grins out of them both, but absolutely giggles while behind the wheel of the XKR-S convertible. The SL63 AMG is the more powerful of the two, but as we know, that doesn't always matter at a racetrack. You'll just have to scroll down and watch the video to see which of them is actually the winner.

Jaguar envisions future without V8 engines

With tighter emissions and fuel economy regulations looming, Jaguar may have to do more than make a small, fuel-efficient hatchback to lower its model range's consumption figures - it also might give up its venerable V8 power, Drive reports. But not anytime soon, says Steven de Ploey, Jaguar's product and marketing director, who recognizes that the V8 can be replaced only by something that offers the same, or better, performance. But he has a word of caution: "We are not wedded to V8s."
In the meantime, de Ploey says there are other ways to reduce emissions. One of the first steps Jaguar could take is to shift away from the use of superchargers, which aren't as good as turbochargers at maintaining efficiency and making power. But he adds that supercharging still is "at the heart of Jaguar's performance proposition," and that the company has addressed the current downsizing trend by "replacing our naturally aspirated V8 with a 3.0-liter supercharged V6."
Consider one of de Ploey's comments on the cancelled C-X75 supercar (pictured) for some clue about Jaguar's future: "Some of the stuff we have already exploited to the extreme in the C-X75 is the kind of thinking for us and is an essential test bed to see how we could evolve from today to something that is sustainable in the future."
