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.

2015 Porsche Macan Turbo

I knew it was a softball question, but I asked it anyway. It's pretty standard for automakers to offer up some examples of competitors when they invite the media to drive a new vehicle for the first time. If not stated outright, it's just as standard for some journalist to query about the competitive set as soon as the Q&A begins. I knew full well that Porsche believes it has a valuable new niche to itself with the 2015 Macan (and especially with the Macan Turbo), but I wanted to hear the answer to the competitor cars question anyway.
Porsche CEO Matthias Müller didn't hesitate for a second to respond. With a half-smirk appropriate to an executive that is about to launch the (very probably) most profitable and best-selling product in his brand's lineup he chuckled, "Of course, I could be arrogant and say this car has no competitors..."
Arrogant? Well, the grinning Müller certainly didn't give off a humble vibe as he proceeded to count down a list of German and British utility vehicles from various classes that are clearly behind the pace of the Macan in either looks, luxury, or sporting prowess - Range Rover Sport, BMW X3 and Mercedes-Benz GLK among them.

'Faster. Farther.' dives into the history of Porsche racing tech

No doubt, Porsche has produced some of the best endurance racecars around, such as the turbocharged, slant-nose 935 of the 1970s and the ground-effects-enhanced 956 and 962 of the 1980s. But the company's most famous racecar, its first overall winner at the 24 Hours of Le Mans, was the 917.
The 917 embodied many of Porsche's technological achievements up to that point, such as the company's first 12- and 16-cylinder engines (the flat-16 was never used in competition), fiberglass bodies that implemented early aerodynamic practices and the use of new, exotic materials, such as magnesium and titanium.
The racecar was commissioned by the head of Porsche Motorsports, Ferdinand Piëch, to win overall at the 24 Hours of Le Mans in 1970, after he realized a loophole in the rules that allowed cars to compete with engines up to five liters in the Sport category if they were also production models. Piëch saw opportunity: the top prototype class was restricted to three liters; the production minimum to compete in Sport was 25 cars. And so, with much effort, Porsche assembled 25 "production" 4.5-liter 917s and had them parked in a neat line for the race inspectors to verify their legitimacy. It didn't take long before people realized the new Porsches were much faster than the prototype racers, with a top speed approaching 250 miles per hour.
