72 Dodge Challenger Rallye on 2040-cars

Dodge Challenger spied exercising supercharged Hellcat Hemi V8

One of the prime complaints against the Dodge Challenger is that, even in SRT8 guise, its 470 horsepower is responsible for hauling over 4,200 pounds of vehicle. For comparison, the 420 hp in the Ford Mustang GT only has to deal with 3,618 lbs. Things only get worse from there, as the higher-performance variants of both the Mustang and the Chevrolet Camaro are far more powerful than an SRT8 without adding on much heft.
So what is Chrysler to do? The correct answer is add a whole lot more grunt to its hefty two-door and even the odds. That's where the all-new Hellcat engine comes into play. We reported on this engine in May, and suggested that the Hellcat, a supercharged powerplant based on a 6.4-liter V8, would easily generate 500 to 570 hp and could likely arrive boasting more than 600 ponies.
Chrysler's ace in its sleeve has now been spied testing, with a number of Hellcat-equipped Challengers running the potent new engine both in more urbanized areas and under the sun of Death Valley. The hoods on these testers have been raised to accommodate the engine, and that camouflage over the fascias of these prototypes is there to hide a larger air intake. We also note what appears to be a new split grille under wraps. As for power output, our spies are now suggesting a Viper-equalling 640 hp from the Hellcat-equipped cars.

Chrysler killing off the 200 Convertible, Dodge Avenger

When Chrysler rolled out the first-generation 200 to replace the Sebring range in 2010, it included replacements for both the sedan and the convertible. The Sebring Coupe, however, was left out of the mix. And now that the second-generation Chrysler 200 is descending upon us, Auburn Hills is paring things down even further. But this time, it's the convertible that reportedly isn't making the cut. Shame, too, since the rendering above shows what could have been quite an attractive droptop.
As our compatriots at Edmunds point out, sales of the convertible model accounted for less than five percent of overall Chrysler 200 sales, and at those numbers, the considerable cost of engineering a new drop-top couldn't be justified. With the Toyota Camry Solara and Volkswagen Eos also gone from the market (well, the VW isn't gone quite yet), the discontinuation of the Chrysler 200 Convertible leaves the affordable convertible segment largely to the sportier likes of the Ford Mustang and Chevy Camaro and smaller European offerings like the Mini Cooper and VW Beetle.
The Chrysler 200 Convertible isn't the only derivative being left behind with the new model: so too is the Dodge Avenger. That will leave a glaring hole in the Dodge lineup, with nothing to bridge the gap between the compact Dart and the larger Charger. Whether the Dodge brand has any plans to replace the Avenger with another model, not to be based on the 200, remains to be seen.

NHTSA closes investigation on 4.7M FCA power modules, no recall

FCA US hasn't had the best time with recalls as of late. Not only did the company recently agree to greater safety oversight and paid $105 million to the government, that came just days after hacking fears prompted a 1.4-million model recall campaign. However, a recent decision to close an investigation by the National Highway Traffic Safety Administration means that the automaker doesn't have to worry about another major recall possibly affecting 4.7 million vehicles, according to the agency's report (as a PDF). Last September, the Center for Auto Safety petitioned NHTSA to investigate an alleged problem with the totally integrated power module (TIPM) on these FCA US models. The group claimed that a fault with the component could cause a variety of maladies, including stalls, not starting, catching fire, unintended acceleration, and airbag non-deployment. At the time, it also submitted 70 cases where this had reportedly happened. According to NHTSA, "no valid evidence was presented in support of claims related to airbag non-deployment, unintended acceleration, or fire resulting from TIPM faults and these claims were found to be wholly without merit based on review of the field data and design of the relevant systems and components." The agency did find signs of an issue with the fuel pump relay in some Jeep Grand Cherokees and Dodge Durangos, but FCA US issued recalls for the problem in September 2014 and February 2015. Without anything else to go on, the Feds don't think it's worth investigating this topic any more.
