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 revisits its remarkable SC East African Safari rally car

Porsche and motorsports just seem to go hand-in-hand. The brand has defined itself by its ability to compete on the track with the concept that racing bred better road cars. While we are used to seeing 911s speeding along circuits around the world, the rear-engine icon's success in rallying is somewhat less well known. The Porsche Museum aims to fix that by highlighting a 911 SC that competed in the 1978 East African Safari Rally.
The 911 rally car definitely projects a '70s vibe. You wouldn't see too many racecars with a pink brush bar sliding through the stages these days, but it looks amazing. Its bank of spotlights and two, giant, hood-mounted horns definitely give away the car's purpose. Best of all, that fantastic Martini livery defines the looks of Porsche racers from this era.
The 911 SC performed well in the East African Safari Rally, but some suspension damage meant that this particular one never raced again. It's been a part of the Porsche Museum ever since. Scroll down to learn a little more about one part of the brand's off-road legacy.

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.
