2015 Dodge Challenger gets 6.4L 485-HP V8 Scat Pack

While it's not seeing the drastic facelift of its brother, the Charger, at the 2014 New York Auto Show, the 2015 Challenger is packing some upgrades of its own. It wears even more retro-inspired styling cues, and there are new 6.4-liter Scat Pack and Shaker trims.
If you thought the Challenger looked retro before, Dodge is taking things even farther with inspiration for the refresh coming from the iconic 1971 model. Up front, it has a new split grille, a larger power bulge in the hood and projector fog lights. At the rear, the classic inspiration continues with split LED taillights with Gloss Black trim, and a rear valance panel redesigned to make the 2015 model look wider and lower.
The '71 motif is carried inside as well with a high-sill center console and aluminum gauge bezels. There's still more than a touch of modernity, with an available 8.4-inch Uconnect infotainment system and 7-inch customizable display between the retro-inspired speedometer and tachometer. For better safety, the Challenger is also now available with forward collision warning, adaptive cruise control, blind-spot monitoring and rear cross path detection. Stability control and electric power steering are standard across all models too.

The biggest gas-guzzlers of 2024: 'The Meanest List' is the opposite of greenest cars

In some circles — especially some automotive circles — bigger is better. This explains the Hummer, for example. In its so-called “Meanest List” of a dozen models, the American Council for an Energy-Efficient Economy (ACEEE) makes no apologies for berating “the worst-performing mass market automobiles” sold in 2024 in the U.S. The most diminutive car on the list is a Chevy Corvette Z06. At the top of this particular heap is the Mercedes-Benz AMG G63, a gas-powered SUV that the environmental agency says was “the worst-performing vehicle of the more than 1,200 models assessed by Greener Cars and has an annual fuel cost over $4,000.” Not to mention its MSRP of around $184,000.

Lonely at the middle of the list is the sole electric, the GMC Hummer EV, which weighs in at 9,000 pounds. The council notes that “though EVs have lower emissions than similarly sized gasoline models, the Hummer demonstrates that size and efficiency, not just fuel source, are important factors in a carÂ’s environmental impact.” ItÂ’s also worth reminding prospective buyers that the average fuel cost of a vehicle on the “Greenest List” eats up only a fifth of the fuel cost of a vehicle on the Meanest List, “showing that greener options can also be more affordable.” The ACEEE also put out a "Greener List" of efficient gasoline and hybrid cars that don't require plugging in.  By the Numbers Green Cadillac Chevrolet Dodge Ford GMC Hummer Jeep Maybach Mercedes-Benz RAM Emissions Fuel Efficiency Green Automakers Truck SUV Electric Hybrid

Chrysler readying Hellcat V8 with Viper-like power

A monstrous supercharged V8 engine could be in store for Chrysler and SRT products, if recent rumors are to be believed. Allpar is reporting that the forced-induction V8 - Chrysler's first, if this goes down - could make its debut this summer.
The story goes that the Hellcat would be based on a 6.2-liter Hemi engine, rather than on the existing 5.7- or 6.4-liter versions of the company's vaunted mill. In any case, the general consensus is that the motor will have gobs of power. Modest estimates call for between 500 to 570 horsepower, with some outliers predicting a figure as high as 600 hp. That figure would put the output would place the Hellcat awfully close to that of the 640-hp V10 in the SRT Viper, too. Allpar contends that a slightly lower powered version would allow Chrysler to keep costs below that of the more powerful Ford Shelby GT500, which might be a sweet spot.
The Hellcat could debut in a number of SRT products. SRT versions of the Charger, Challenger and 300 are all up for grabs, as is the rumored SRT Barracuda.
