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.

Stellantis aims to eliminate separate inverter, charger to improve EV efficiency

Stellantis has announced that, in collaboration with French battery company Saft and French National Center for Scientific Research, has made significant progress in eliminating two major components of an electric vehicle powertrain: the on-board charger and the power inverter for the motor. The company claims that doing this will allow for better space use in vehicles, as well as improvements in efficiency, cost and reliability of components. As a quick primer, also explained in the below video, the on-board charger and power inverter are sort of translators to get the right current to different parts of the electric powertrain. The on-board charger takes AC power from the grid and converts it to DC to charge the batteries. Then when power goes from the batteries to the electric motor, the power inverter converts that DC power back to AC. These components aren't exactly small. Frequently you'll find them packaged somewhere under the hood. What Stellantis and its cohorts have developed, and have been using on a test vehicle since last summer, are small power inverter boards that can be mounted very closely to the battery packs. They can handle both conversion needs, for charging and discharging, instead of needing two separate devices. The most obvious perk to this is that you can do away with those traditional components and free up more space, either for making smaller vehicles without losing interior volume, or adding space to a vehicle that wouldn't have had it otherwise. There's the additional benefit of reduced weight, something that EVs struggle with. Stellantis also claims improvements in efficiency, reliability, and cost, however, it didn't go into detail as to how this setup would do that exactly. We'll try to get in touch with representatives from Stellantis in order to get more information. We're still a ways out from seeing this technology in production Stellantis vehicles. The company said it aims to apply it to vehicles by the end of the decade. Saft is also looking at using it on stationary battery systems as well. So maybe we'll see it on a 2029 Ram 1500 REV, but for now, we'll be living with traditional chargers and inverters. Related Video: Green Alfa Romeo Chrysler Dodge Fiat RAM Technology Electric

Dodge recalling 2k SRT Hellcat Challengers and Chargers for fuel leak

Bad news for fans of the obscene output of the Dodge Hellcat twins, as FCA has announced a voluntary recall of both 707-horsepower variants of the 2015-model-year Charger sedan and Challenger coupe. According to FCA, a total of 2,211 cars are being recalled after a dealer discovered a "possible fuel leak" during a pre-delivery inspection. Despite getting cleared by suppliers, FCA claims its engineers found "improperly installed" hose seals. Owners of affected vehicles will receive notification and be asked to report in for repairs. Of the vehicles affected, the overwhelming majority, 2,012, were sold in the US market. The remainder were sold in Canada (148), Mexico (30) and just 21 outside of North America. Scroll down for the official release from FCA. Related Video: Statement: Hose Seals March 1, 2015 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 2,211 cars globally to replace fuel-delivery components that may leak. An FCA US dealer alerted the Company to a possible fuel leak following a pre-delivery vehicle inspection. These components had passed the supplier's leak-testing, but FCA US engineers launched an investigation and discovered certain hose seals may have been improperly installed. The Company is unaware of any related injuries, accidents or customer complaints. Affected are model-year 2015 Dodge Challenger SRT coupes and Dodge Charger SRT sedans equipped with 6.2-liter V-8 engines. There are an estimated 2,012 in the U.S.; 148 in Canada; 30 in Mexico and 21 outside the NAFTA region. Affected customers will be notified and advised when they may schedule service.
