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.

Porsche 911 Cabriolet refresh may hide new engine

If we learned nothing else from our recent frolic through Porsche's secret museum, it's that the automaker goes to incredible lengths to disguise future products during initial testing. Just as a number of cars in that Stuttgart bunker hid the true identity of developmental mules (like the Audi-V8-powered 911), such could very well be the case with these spy shots showing what, on the surface, appears to be simply a facelifted 991 911 Cabriolet.
Similar to what we saw last month on a 911 coupe, this Cabriolet has obvious styling modifications made to the front and rear fascias suggesting that the 911's still-fresh appearance is already set to get a few tweaks. The big news here is at the rear of the car. The additional vents on the lower edge of the fascia and the mocked-up vent above the engine leads our spy photographer to believe that a new engine could be tucked under the body work - likely a smaller-displacement, turbocharged flat-six focusing more on improving fuel efficiency and reducing exhaust emissions rather than performance.
We last heard rumblings of such a detuned 911 back in August, but could this be our first look at said new model? Have a look for yourself, and let us know what you think - either about this mule specifically or the idea of a "green" 911, in Comments below.

Next-generation Panamera will spawn variants, Sport Turismo in the running

A few years ago it took actual willpower not to consider what kinds of cool derivatives Porsche could make with the Panamera. Our fancies were helped by patent drawings of a Panamera convertible, rumors of a two-door 928 GT and internal Porsche sketches of such a car, and report after report after report that the current, second-generation Panamera would begin to expand the family. That hasn't happened, but according to a new report in Auto Express, the next Panamera will be the one to begin the bifurcation. Wolfgang Hatz, the brand's head of research and development, told the mag that, "We have prepared it for a lot of derivatives, personally I like very much the Sport Turismo." The Panamera Sport Turismo, remember, was the hybrid, concept wagon that rolled into the 2012 Paris Motor Show and made everyone ask, "Why didn't you build this design from the beginning?" It could have been Hatz's English, but after professing his ardor for the Sport Turismo, the executive said, "But there is a good chance for more derivatives." We're not sure if that means the Sport Turismo is all but approved, or if he was speaking of the third generation Panamera's new MSB platform in general. Even though Hatz mentioned a coupe and convertible, it sounds like that latter variant won't be happening, Hatz saying that the brand already has the Boxster and 911 Cabriolet. We're willing to forgive that omission – who's really looking for a four-door convertible, anyway? – and welcome the Sport Turismo first if Hatz will please please please get us a new 928.
