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.

Dodge Scat Packages add Mopar performance upgrades in three stages

Dodge has revealed what it calls Scat Package Stage Kits that enhance the performance of the Charger and the Challenger equipped with the 5.7-liter V8, and the Dart equipped with the turbocharged 2.4-liter inline four-cylinder engine. The Scat Packs use Mopar performance parts that also can be bought separately. Most of the upgrades increase engine output, but Dodge somehow manages to not specifically mention the power gains associated with each Scat Pack.
The three Scat Packs offered for the V8-powered cars focus on higher power ratings, and each stage comes complete with a unique engine-management calibration to optimize output. Stage one comes with a cold-air intake and a cat-back exhaust; stage two adds a performance camshaft; and stage three really gives you the goods, adding ported polished cylinder heads and performance headers.
For the Dart, the Scat Packs focus on engine, transmission, chassis and brake upgrades. Stage one will net you a cold-air intake, a short-throw shifter and slotted rotors with performance brake pads; stage two adds a cat-back exhaust system and an engine-management calibration to increase output by taking advantage of premium-octane gasoline; and stage three adds 13-inch vented brake discs up front clamped by four-piston calipers, suspension with adjustable springs and struts and performance front and rear antiroll bars.

Watch 1,414-hp worth of Dodge Challenger SRT Hellcat do stereo burnouts

When Dodge announced that the 2015 Dodge Challenger SRT Hellcat would produce 707 horsepower and 650 pound-feet of torque from its supercharged 6.2-liter V8, automotive enthusiasts were shocked. The company had promised us that it would be powerful, but no one expected for the muscle car to post even larger numbers than the range-topping Viper.
Car and Driver recently got ahold of two new SRTs and decided that the only proper way to show them off was by lighting up the rears in stereo. With a combined 1,414 horsepower, the pair of them make burnouts from the Hellcat V8 look as easy as breathing. The tires start spinning at the slightest provocation and just don't stop. If you buy one of these, it looks like you and the employees at the local tire store are going to be on a first name basis.
