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.

Indications of 825 hp and emissions issues for Hellcat called 'speculation' by Chrysler

The 2015 Dodge Challenger SRT Hellcat is probably one of the hottest cars of the moment mostly because of its insane, 707-horsepower supercharged V8. However, there are conflicting reports coming out that the powerplant might be having problems with its emissions compliance and may be capable of even more power.
Jalopnik says that an unnamed source within Fiat Chrysler Automobiles told it that the Hellcat was having problems meeting emissions standards at its 707-horsepower tune. The person claimed that the automaker has been testing the V8 with different types of sensors, possibly to make it a bit cleaner in the future. Autoblog spoke to SRT spokesperson Dan Reid, and he said about the claimed poor emissions, "It's totally speculation."
The source also claimed that the Hellcat had been dynoed at a monumental 825 horsepower, internally. Based on the other rumor, though, it's hard to imagine the engine being emissions compliant like that. Autoblog also asked Reid about this speculation about more power and was told, "They are totally speculating about that."

Dodge Challenger Shakedown: '71 body, new guts

While Jeep has created a number of vintage-bodied custom vehicles with modern components, this year's SEMA show plays host to Dodge's take on the idea. The Shakedown concept began life as a 1971 Challenger and ditched almost everything in it, including the engine and chassis. What's left is a modern car with a retro look. The chassis was a particularly complicated part of the job, since the Challenger was originally a unibody car. However, Dodge chose to separate the Challenger's iconic body from its structural parts, and moved it onto a custom, one-off chassis from which the body can be removed as needed. The chassis also carries lowered suspension, Challenger Hellcat brakes, and a 6.4-liter 392 Hemi V8 connected to a six-speed manual transmission from the Viper. Dodge also installed the engine using the new Hemi engine swap kit from Mopar. With the shaker cold-air intake and custom exhaust, the Shakedown's powerplant makes 485 horsepower.

Dodge shaved off the drip rails, door handles, and turn signals for a cleaner look, and also fitted the grille, headlights, and taillights from a 2017 Challenger. The whole thing is finished in matte black paint with a "vibrating" stripe offset on the left side. The Shakedown also gets 20-inch Slingshot rear wheels and a pair of custom 19-inch versions for the front. On each fender is a bright red "392" decal that uses the same font as the labels on classic Mopars 360 cubic-inch V8s. Inside, the Shakedown gets the same radical upgrade as the chassis. Two Viper seats accompany a Viper steering wheel, and the rear seats are gone altogether. The Viper gearbox is shifted with a Challenger Hellcat gear knob, and carbon-fiber accents and leather adorn the wheel, door panels, instrument panel and center console.
