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.

Dodge Durango gets performance Mopar options for R/T, SRT

Fiat Chrysler is showing new performance add-ons for the 2018 Dodge Durango R/T and SRT models at the Chicago Auto Show, including the familiar Dodge dual center stripes and a new Mopar exhaust system. The 475-horsepower SRT model, which is powered by a 6.4-liter Hemi V8, will also offer a lowering spring kit and a carbon-fiber instrument panel. The signature two-stripe treatment blankets the three-row SUV from the front to rear fascia and is tailored to the signature NACA duct-hood vent. It'll come in five different colors — bright blue, flame red, gunmetal low gloss (metallic finish), low-gloss black and sterling silver — and retail for $1,195 starting in March. View 7 Photos Mopar developed its new bolt-on performance exhaust systems with Dodge SRT engineers and designers to improve flow and achieve that sweet sound. It features a chromium 304 stainless steel construction to make it more resistant to corrosion, with stainless steel band-style clamps and welded and polished 4-inch tips. It costs $1,595 for the Durango R/T and is available now. On the SRT, the price goes up to $1,850, with the package available in the second quarter. New Mopar springs improve the Durango SRT's high-speed cornering stability and consistency by lowering the SUV an average of 15 millimeters, or 0.6 inches. They were developed with proprietary Dodge SRT data not available to the aftermarket to tune the lowering springs to the factory dampers, giving the vehicle less rear-end squat during acceleration, less nose dive while braking and reduced body roll on corners. MSRP on the package, which is available now, is $325. For just under $2,500 you can get the SRT Interior Appearance Group package, which adds a premium-wrapped carbon-fiber instrument panel and door bezels, Dinamica soft-touch headliner and accent paint on speaker trim rings. The Chicago Auto Show is open to the public Feb. 10-19.

A look at the Dodge Demon's drag settings, modes, and go-fast tech

In the same video that gave us a peek at the 2018 Dodge Challenger SRT Demon's performance stats, there's a serious dump of info on the tech and tools that will likely help this muscle coupe slaughter drag strips. Dodge has outlined a few of them for us and we're using the power of inference to figure out the rest. Here's what we've gathered. A lot of these hints come from the Demon's version of Performance Pages, the infotainment screens that show what SRT models are doing and let the driver change the powertrain and chassis setup. There are a lot of Demon-only features, including line lock, a quick cooldown mode for the supercharged engine, and data recording. And of course there are pages to show a digital time slip with acceleration and braking figures, a g-load plot, and lots of gauges to track temps and levels. The engine output is shown in the video on a special Dyno page. It tracks horsepower and torque over time on the upper graph, and engine rpm and shift points on the lower graph. And we think it's still hiding something. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Any good drag car has a line lock, allowing the driver to lock the front brakes and leave the rears free to do a nice tire-warming (or tire-shredding, depending on length) burnout. Ford has it on the Mustang, Chevy puts it on the ZL1, and now Dodge is adding it to the Demon. It should help get the giant Nitto tires up to temp for a drag run. And once the tires are warm, there's launch control, just like on the SRT Hellcat, with selectable rpm to dial things in for the conditions. The Demon also has a shift light in the cluster, and the driver can set a shift point individually for each gear. After each drag run, you can activate Quick Cooldown, which Dodge says uses the first production application of After-Run Chiller – it runs the cooling fan and intercooler coolant pump with the engine off until the coolant reaches its target temp. It's shown in one of the slides above. The checklist on the left side of that page suggests it requires a set of conditions be met to work: engine off, hood open, and sufficient battery level. This further reinforces our theory that the supercharger is going to make big boost, beyond the Hellcat's 11.6 psi. And while you're waiting for the supercharger to cool off for another run, you can review the performance data the car records.
