2015 Dodge Challenger SRT Hellcat has 707 glorious horsepower [w/video]

Hold onto your butts. "600-plus horsepower" is what we were told to expect from the 2015 Dodge Challenger SRT with its 6.2-liter supercharged Hellcat V8 engine. But as we've just learned, those were incredibly conservative numbers. Dodge has officially announced that the range-topping Challenger will hit the asphalt with 707 - seven hundred and seven - horsepower, making it the "most powerful muscle car ever."
Of course, 707 hp is only part of the story, as the Hellcat has also been confirmed to produce 650 pound-feet of torque. All that power will run exclusively to the rear wheels through an eight-speed automatic transmission that differs from other Challengers. The new gearbox, 8HP90 (rather than the 8HP70) is "upgraded to handle the extra power and torque," says Dan Reid, SRT's manager of product design and motorsports.
We certainly hope you're prepared to spend a ton of money replacing tires.

1 Of 1 Dodge Viper looks a fabulous mess in Chicago

Earlier this year, we told you about the new Dodge Viper 1 Of 1 program, which offers buyers the chance to customize their supercars to the tune of some 25 million different combinations. With 8,000 paint colors, 24,000 hand-painted stripe patterns, 10 wheel options, and 16 interior trims to choose from, you'd be right to think that the possibilities for personalization are endless, and can probably get a little weird. That's kind of what's going on here in Chicago, with a Viper showcar that's definitely... unique. It doesn't really look bad, necessarily. It's just kind of strange. We call this color job, "Oh no, there are tiny paint cans falling from the sky, but I simply can't stop driving 200 miles per hour." And when it came time to spec wheels, it looks like FCA US said, "Aw heck, let's just use all of 'em." You'll definitely want to take a look at this unique creation, in the gallery above. And be sure to let us know if you think this Viper is hot or not, in Comments. Related Video:

Killing the Dart and 200 might lower FCA's fuel economy burden

Killing the Dodge Dart and Chrysler 200 could allow FCA US to take advantage of an intriguing quirk in the next decade's fuel economy regulations. By increasing its ratio of trucks versus cars, the automaker might not need to worry so much about hitting the more stringent efficiency rules. At first thought, it might seem harder for an automaker with a ton of trucks to meet the government's mandated 54.5 mile per gallon corporate average fuel economy for 2025. However, every company doesn't need to hit that lofty figure, according to The Detroit Free Press. The exact target varies by the product mix between trucks and cars. "While passenger car and light truck categories have separate CAFE targets, it's still true that more trucks versus cars in a company lineup means a lower combined CAFE target," Brandon Schoettle, Project Manager Sustainable Worldwide Transportation at the University of Michigan Transportation Research Institute, told Autoblog. "While passenger car and light truck categories have separate CAFE targets, it's still true that more trucks versus cars in a company lineup means a lower combined CAFE target." FCA US' current product blend has 80 percent pickups and CUVs, which means the company stands to benefit from a lower fuel economy target. It might not seem entirely fair environmentally, but this is a great move from a business perspective. The new CAFE rules aren't set in stone, according to The Detroit Free Press, but potentially taking advantage of the regulation is just one more reason to cut the Dart and 200. Modern crossovers also aren't gas guzzlers like older SUVs, which could make it easier to hit the fuel economy target. "Utilities offer practicality and versatility that cars do not, and now, built on car architectures, they do not penalize consumers on fuel economy as they once did," AutoTrader Senior Analyst Michelle Krebs told Autoblog. Schoettle warns that FCA is still making a gamble by killing the small sedans. "Depending on the previous sales volumes and how much these vehicles might have exceeded their specific CAFE targets, it's possible that these cars helped earn CAFE credits for FCA that they could bank for future use," he said.
