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.

FCA seeks partner to keep building Dodge Dart, Chrysler 200

Mere weeks after FCA announced it was shutting down production of the Dodge Dart and Chrysler 200, new hope emerges to give the sedans a stay of execution. Speaking at the Geneva Motor Show last week, Sergio Marchionne said that the company was looking for a partner "who is better at it than we are and who has got capacity available" in order to continue building the models on its behalf. "There are discussions going on now," said Marchionne, according to Motor Trend. "I think we will find a solution. We continue to talk. It's both a technical solution and an economic one. We need to find a solution that works economically." Contracting vehicles to be manufactured offsite is more common practice among European automakers than it is with American ones. Chrysler's former patron Mercedes, for example, has the G-Class built for it by Magna Steyr in Austria, the A-Class by Valmet in Finland, and the R-Class by AM General in Indiana (even though it's no longer sold in the US). This arrangement would, on the surface at least, appear more similar to the deal that Toyota struck with Mazda to build the Scion iA, drawing on the contractor's expertise and capacity to build the small sedan on the client company's behalf. Only rather than basing a new model on one of the partner's existing ones, this deal would ostensibly continue building FCA models on FCA platforms using FCA components. We'll have to wait to find out with whom FCA strikes up the manufacturing deal, but we wouldn't be surprised to see Marchionne turn to a partner he already knows. The company is, after all, at the center of an intricate web of joint ventures and manufacturing contracts. The Fiat 124 Spider, for example, is built by Mazda. The Fiat Sedici that preceded the 500X was built by Suzuki. Models like the Dodge Stealth and Eagle Talon were built in Illinois at the Diamond-Star Motors joint venture before Mitsubishi took it over altogether. And Dodge continued selling the Mercedes-made Sprinter long after DaimlerChrysler split. The Ram ProMaster, though built by FCA in Mexico for the North American market, stems from a partnership in France with PSA Peugeot Citroen. And the ProMaster City is built in a joint-venture plant in Turkey, from which it's also sold by GM as an Opel in Europe and a Vauxhall in the UK. With all those deals coming and going, after all, what would one more add to the complexity?

The Dodge Demon gets a Drag Mode and a lesson in Newtonian physics

It's Thursday morning, which means we have more news on the upcoming Dodge Demon, the pumped-up Challenger Hellcat variant that's looking to cause mayhem at a drag strip near you. This week's video, "Third Law," shows the Demon's revised suspension in action and displays another one of SRT's cryptic messages. Dodge claims that the 6.2-liter supercharged Hemi V8 in the Hellcat twins is compromised because it's fitted to a car that needs to be comfortable on the street in addition to a performer on the drag strip. Not so with the Demon, as Dodge says the car is "designed to be highly competent in all drive modes and configurations," including the all-new Drag Mode. Dodge says details about the new mode will trickle out over the next few weeks, but all the info this week focused on suspension. The "Third Law" in this week's title refers to Isaac Newton and motion: "When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body." We're not sure what Newton would have thought seeing the sidewall wrinkling Nitto NT05R drag radials in action, but he'd probably have a reaction of some sort himself. An ideal suspension setup for the drag strip makes for a poor setup on the road. As Dodge puts it, the "old school" way to set up a drag car was to "get the quickest reacting springs upfront, the softest rebound front shocks that wouldn't restrict the springs' reaction, remove any restrictions (sway bar) and increase the compression of the rear shocks." This would give a car great front to rear weight transfer but made for very poor lateral direction control, meaning minor corrections were difficult. The Demon's Drag Mode will use electronics to give the car the best combination of launch and lateral stability. Dodge listed some of the parts to help aid in this goal. They also gave us a few equations that we can't make sense of. Let us know if you have any clues. Hardware: 35 percent lower rate front springs/28 percent lower rate rear springs 75 percent lower rate hollow front sway bar/44 percent lower rate rear sway bar Drag-tuned Bilstein Adaptive Damping Shocks Software: Rear = F/F and Front = F/S F/F – F/S maintained @ wide open throttle (WOT) F/F – F/F < WOT Traction control disabled/ESC maintained Result: 13.5=575@500 Related Video: This content is hosted by a third party.
