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 919 Hybrid revives Porsche's factory Le Mans efforts

After months of teasing with camouflaged testers, Porsche has finally unveiled its prototype entry for the 2014 World Endurance Championship, the 919 Hybrid. Porsche, you may recall, hasn't had campaigned a factory team at Le Mans in years, so the 919 is nothing less than their recommitment to endurance racing.
Combining a 2.0-liter V4 (yes, a V4) that revs to 9,000 rpm, the 919 produces around 500 horsepower with a pair of energy recovery systems. The first system recovers the heat energy from exhaust gasses as they pass through an electrical generator, while the second system is a bit more familiar. Using a setup similar to what is found on the production 918 Spyder, a generator on the front axle recovers kinetic energy from the brakes, which is subsequently stored in a battery system. That power can then be sent to the front wheels at the driver's command, effectively turning the 919 into an all-wheel-drive racecar.
Despite these various forms of motivation, Porsche doesn't claim to be seeking outright power supremacy, with Chairman Matthias Müller saying, "In 2014, it will not be the fastest car that wins the World Endurance Championship series and the 24 hours of Le Mans, rather it will be the car that goes the furthest with a defined amount of energy. And it is precisely this challenge that carmakers must overcome. The 919 Hybrid is our fastest mobile research laboratory and the most complex race car that Porsche has ever built."

Ferrari return to Le Mans looking more likely?

Statements made by Ferrari president Luca di Montezemolo may indicate that the Italian brand could return to a form of racing it's been absent from for 40 years - prototype racing. That's right, LMP1 could see a factory Ferrari team for the first time since 1973, if a report from ESPN F1 is to be believed.
"We have won with the 458 GTE, but I also quite like the idea of racing at Le Mans in the highest category: who knows, maybe one day we can return and win, say thanks and come home," Montezemolo said. "Maybe we should give it some consideration..."
These seemingly idle, off-hand comments might not hold much water, were rumors about Ferrari's return to prototype racing not swirling as recently as August. There's also the fact that the upcoming, 1.6-liter, turbocharged V6 being used for Formula One complies with the Automobile Club de l'Ouest's own LMP1 regulations, according to ESPN. Finally, Ferrari returning to Le Mans might also explain this video of a camouflaged Ferrari LaFerrari testing a new turbocharged engine, which we showed you a few weeks back. There's a fair chance that what we're actually seeing in that video are the early stages of a new Ferrari prototype testing.
