Hellcat no help to Fiat-Chrysler's bottom-of-the-pile mpg average

What, you expected the "fastest muscle car ever" to help fleetwide fuel economy? Nope, don't think that's going to happen. That means Fiat Chrysler will likely to continue to languish at the bottom of the heap when it comes to fleetwide fuel economy among the largest automakers serving the US, especially as the automaker starts to sell its Dodge Challenger SRT Hellcat. A few hundred Fiat 500E electric vehicles aren't going to turn the trend around. See, Chrysler has once again finished at the bottom of the list when it came to fleetwide fuel economy among automakers for 2014 model-year vehicles, according to a preliminary study by the US Environmental Protection Agency. Chrysler and Fiat had an average of 21.1 miles per gallon. That substantially lagged the overall 24.2 mpg average, but it was an increase from the company's 20.9 mpg average last year and the 20.1 mpg average two years prior. For 2014, General Motors had the second-worst fleetwide fuel economy at an even 22 mpg. Fiat Chrysler does say it's working on improving its fuel economy, according to Automotive News. The company plans on making its inline-four-cylinder and V6 engines smaller, and will sell more vehicles with eight- and nine-speed transmissions. Heck, there's even a plug-in hybrid version of the Chrysler Town & Country minivan in the works for late 2015, and the company can tout fuel-efficiency gains with the Chrysler 200 and Jeep Cherokee. We would be remiss if we didn't note that, compared to its muscle-car forefathers, the Hellcat actually performs pretty well at the pump. Last month, word got out that the 2015 Challenger Hellcat, equipped either with a six-speed manual or an eight-speed automatic transmission, got a combined fuel economy of 16 mpg. Heck, the automatic-tranny version got 22 mpg on the highway. And that's for a car with 707 horsepower and a 10-second quarter-mile time. Still, with the pedal floored, the car can burn a gallon and a half of fuel per minute. Ouch.

Dodge celebrates big B-day with 100th Anniversary Editions muscle cars

Being in business for 100 years is a HUGE milestone, so we hope Dodge has more in mind to celebrate its centennial than just a special edition package for the 2014 Charger and Challenger. Called the 100th Anniversary Edition package, this collection of cosmetic enhancements will be available in limited quantities for both cars at a cost of $2,500.
Ordering a Charger or Challenger with the 100th Anniversary Edition package means starting with either a V6-powered SXT Plus or V8-powered R/T Plus model. They can each be ordered in many colors, but only the High-Octane Red Pearl Coat above is an anniversary exclusive. Each car also comes with an anniversary-exclusive set of 20-inch, five-spoke wheels with what Dodge calls "Granite Crystal pockets," a texture that's also mirrored on each car's grille.
Of course, there are commemorative badges galore affixed to the exterior of each car, including "Dodge Est. 1914" fender badges and "100" logos on the center caps of each wheel. The styling theme of each car's interior is a bit more interesting, with Dodge designers trying to evoke "the patina and machinist legacy of John and Horace Dodge," the company's founders. To that end, the leather interior can be had in Molten Red or Foundry Black Nappa, and each features a custom cloud overprint that makes the hide look like a working man's dirty dungarees. Designers also used brass-colored accent stitching on the interior's leather trim pieces, and affixed more "Dodge Est. 1914" badges to the front seat backs and floor mats. We do like the flat-bottomed steering wheel, and the Challenger 100th Anniversary Edition gets exclusive white gauges faces and the Charger black. The "100" on each car's speedometer is also highlighted in red.

Chrysler almost smothered the Hellcat before it lived

Chrysler's 6.2-liter supercharged Hellcat V8 was an absolute sensation from the very moment it was announced, and honestly, how could it not have been? Packing 707 horsepower and 650 pound-feet of torque, its numbers immediately put every other production muscle car (and many supercars) to shame. Plus, we soon learned that would be wrapped in a package retailing for around $60,000 - a pittance compared to other vehicles offering similar grunt. However, the Hellcat almost never got the chance to rumble under the hood of the Challenger and Charger.
The Hellcat was initially proposed back in 2011, back when Fiat was deciding its future strategy for Chrysler Group, according to Automotive News. At the time, the company was just emerging from its bankruptcy doldrums, and an ultra-high-performance V8 wasn't exactly a must-have item. The program didn't move forward. However, SRT engineers kept fighting, according to AN, and four months later, they received the green light to pull the project off the shelf and continue developing the Hellcat. The muscle car world is certainly better for that decision.
The work of those engineers focused on taking Chrysler's standard 6.2-liter V8 and making it reliably handle all of the extra power from the supercharger. "It came down to micron levels of changes in the crank to be able to withstand the pressures of the engine," said Chris Cowland, director of advanced and SRT powertrain, to Automotive News. The changes amounted to switching out about 91 percent of the parts to make the Hellcat, including some quite minuscule alterations. For example, the washer holding the supercharger pulley is embedded with industrial diamonds to keep it from slipping.
