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.

Mopar maneuvers into SEMA with a multitude of modified models

As the aftermarket and performance arm of Fiat Chrysler Automobiles, Mopar has a duty to extract everything from the company's models that it can, and there's no better place to show all of its work off than the annual SEMA Show.
Dodge really gets in on the act this year with several customs to show off different parts of the brand's performance heritage. Perhaps the most interesting among them is the track-prepped Viper ACR Concept (pictured above). It wears a custom body kit to produce even more downforce, thanks in no small part to a monstrous wing at the back. To shed weight, most of the interior is stripped out, as well. Next up, the Challenger T/A Concept takes inspiration from '70s Trans-Am racing in a livery of Sublime Green and matte black paint. The center scoop in the hood keeps the 6.4-liter V8 fed with cool air, and the special's 20-by-9.5-inch matte black wheels keep it planted in the corners.
Also getting the once-over from Mopar is the Charger R/T. It wears the division's body kit, and under the hood, a cold-air intake keeps the 5.7-liter V8 breathing. The suspension is retooled to hold the road better with a coil-over kit, upgraded sway bars and strut tower braces for the front and rear. The company is also showing off a snazzy blue Charger with a mean look. The final Dodge getting work from Mopar is the Dart R/T Concept with bright, O-So-Orange paint and a matte black hood with a scoop hooked directly to the air intake. The performance-oriented design is finished off with a coil-over suspension and big brake kit, as well.

Dodge Viper to out-Hell the Hellcat with supercharged V10?

The Viper wouldn't be the Viper if it wasn't the most powerful model under the Chrysler umbrella. But with the arrival of the Hellcat engine in the Dodge Charger and Challenger, the Viper has fallen behind in the bragging rights department: where the new supercharged V8 produces 707 horsepower and 650 pound-feet of torque, the naturally aspirated V10 offers "only" 640 hp and 600 lb-ft - gargantuan output figures by almost any other standard, but crucially behind on the SRT power scale. Conner Avenue is going to have to do something about that.
Although the Hellcat's engine reportedly won't fit under the Viper's hood, SRT is now rumored to have another trick up its sleeve: supercharge the existing V10. According to the Pentastar performance enthusiasts at allpar.com, Chrysler has already taken delivery of the first such prototype engines so that it can begin the process of fitting it into an upgraded Viper.
The spooled ten-pot is tipped to produce around 800 hp and 650 lb-ft of torque. More than that and the Viper's drivetrain, chassis and bodywork would have to be substantially reworked. Though beefier transmissions are available, fitting them would reportedly set off a domino-game of changes required to handle the added torque. Which may be something Chrysler would be prepared to do for the next-generation model, but in the meantime, 800 hp could prove enough to put the Viper back atop the Mopar performance ladder where it belongs, and give it an edge against the new Corvette Z06 to rekindle sales.
