Chrysler extends fuel tank warranties on LX cars, NHTSA ends probe

The National Highway Traffic Safety Administration has ended its investigation of 153,817, 5.7-liter and 6.1-liter Hemi V8-powered 2006 Chrysler 300, Dodge Charger and Dodge Magnum models after reports of stalling. Chrysler has responded by granting a lifetime warranty on the fuel tanks for these vehicles.
NHTSA received 299 reports of engines stalling while the models were stopped or driving at low speeds, and began an investigation. The government agency found that the control valve shutoff float in the V8s' 19-gallon fuel tank could malfunction if the fuel had too high of an ethanol content. In many cases, the valve would break in the open position, allowing the tank to be overfilled, which would then cause the cars to stall. However, there were no accidents reported, and the vehicles could be restarted immediately.
There will not be a recall on these vehicles because, "the condition represents a low risk to motor vehicle safety and is adequately addressed by Chrysler's extended warranty," NHTSA said to The Detroit News.

The biggest gas-guzzlers of 2024: 'The Meanest List' is the opposite of greenest cars

In some circles — especially some automotive circles — bigger is better. This explains the Hummer, for example. In its so-called “Meanest List” of a dozen models, the American Council for an Energy-Efficient Economy (ACEEE) makes no apologies for berating “the worst-performing mass market automobiles” sold in 2024 in the U.S. The most diminutive car on the list is a Chevy Corvette Z06. At the top of this particular heap is the Mercedes-Benz AMG G63, a gas-powered SUV that the environmental agency says was “the worst-performing vehicle of the more than 1,200 models assessed by Greener Cars and has an annual fuel cost over $4,000.” Not to mention its MSRP of around $184,000.

Lonely at the middle of the list is the sole electric, the GMC Hummer EV, which weighs in at 9,000 pounds. The council notes that “though EVs have lower emissions than similarly sized gasoline models, the Hummer demonstrates that size and efficiency, not just fuel source, are important factors in a carÂ’s environmental impact.” ItÂ’s also worth reminding prospective buyers that the average fuel cost of a vehicle on the “Greenest List” eats up only a fifth of the fuel cost of a vehicle on the Meanest List, “showing that greener options can also be more affordable.” The ACEEE also put out a "Greener List" of efficient gasoline and hybrid cars that don't require plugging in.  By the Numbers Green Cadillac Chevrolet Dodge Ford GMC Hummer Jeep Maybach Mercedes-Benz RAM Emissions Fuel Efficiency Green Automakers Truck SUV Electric Hybrid

Dodge Durango could get eTorque mild hybrid system in 2020

The 2020 Dodge Durango appears slated to get a mild-hybrid powertrain option. That's the word from moparinsiders.com, which unearthed the news from documents relating to contract negotiation between the FCA and the UAW. Although the documents give no further details, it's a pretty safe bet that we're talking about Chrysler's eTorque mild-hybrid system, which was introduced on the Ram 1500 pickup and has since been extended to the Jeep Wrangler. Currently, the Wrangler offers the eTorque system on the 2.0-liter inline-four and the 3.6-liter Pentastar V6, both on the Sahara model only, while the Ram 1500 makes the mild-hybrid system standard with the 3.6-liter V6 and an option with the 5.7-liter Hemi V8. The V6 eTorque powertrain makes 305 horsepower and 269 pound-feet of torque (Ram) or 285 horsepower and 260 pound-feet (Wrangler). The Wrangler's four-cylinder eTorque is good for 270 horses and 295 lb-ft. The V8 version in the Ram is good for 395 horsepower and 410 lb-ft of torque. In all cases, the eTorque system does not increase peak output over the standard version of the gasoline engine. The mild-hybrid system does provide a minor fuel-economy boost. In the Wrangler, the 3.6-liter with eTorque has EPA city estimates that are 1 mpg better than without the system. On the Ram's V8, eTorque adds 2 mpg city and 1 mpg highway. (The 2.0-liter sees no improvement in its EPA ratings.) It's not known whether the Durango will add eTorque to its V6, or V8, or both. Either engine could do with a fuel-economy boost, as the V6 is EPA rated at 19/26 mpg city/highway (RWD) and 18/25 mpg (AWD), while the V8 version has estimates of 14/22 mpg. Related Video:
