Jeep still working to improve Cherokee's 9-speed auto

Fiat Chrysler is hoping an upcoming software update will stem the tide of consumer complaints surrounding its nine-speed automatic transmission. Owners of the 2014 Jeep Cherokee have reported a number of problems on the National Highway Traffic Safety Administration's SaferCar.gov website, since the new model and its troubled gearbox arrived way back in October 2013. The software update is "intended to keep the vehicle performing as intended, and to prevent durability issues from occurring in the future," an FCA spokesperson told Automotive News, and will be available to owners of both the 2014 to 2015 Jeep Cherokee and the 2015 Chrysler 200, which also uses the 9AT. While FCA will be notifying consumers of the update, owners can also request the software reflash if they happen into their dealer before then. Despite the widely documented problems with the transmission, the only complaints on NHTSA's website relate to the 2014 Cherokee – neither the 2015 Jeep nor the 200 have received any complaints. That bodes well as FCA prepares to begin deliveries of the 2015 Jeep Renegade and launch the Fiat 500X, both of which pair the 9AT with the 2.4-liter Tigershark four-cylinder. "We have had to do an inordinate amount of intervention on that transmission, surely beyond what any of us had forecast," FCA CEO Sergio Marchionne told Automotive News. "There are things that we have done – that we continue to do. Our proactive customer care intervention has actually increased in intensity on these vehicles in 2014, especially in the second half." What's fascinating about the 9AT's problems are that they haven't been the fault of manufacturer ZF, but have related to software that wasn't "mature" and had "teething problems," Marchionne has said previously, AN reports. With the lack of criticism for the 9AT in 2015 models and this pending software update, though, here's hoping that FCA has finally figured out its fuel-sipping gearbox. Related Video:

Mopar highlights wild SEMA creations, AWD Challenger Concept

Thanks to 15,345 square feet of display area, FCA US' Mopar division certainly has ample space to display its parts and accessories at the SEMA Show. To lure attendees to check out all of those cars and components, the company is now revealing ten tuned vehicles for this year's aftermarket event. This isn't even the brand's whole fleet for the show, but it includes some major highlights for Dodge and Ram fans. A lack of traction traditionally makes rear-wheel-drive muscle cars dismal to drive when the weather gets slippery, but the Dodge Challenger GT AWD Concept (above) solves that age-old problem at SEMA. In addition to powering all four wheels through an eight-speed automatic, it boasts an angry-looking, wide-body kit with aggressively flared wheel arches. The asymmetrical stripe with Header Orange accents also adds some extra panache to the Destroyer Grey and Matte Black color scheme. The coupe can back up the macho look thanks to the Scat Pack 3 Performance Kit that adds 75 horsepower and 44 pound-feet of torque to the 5.7-liter V8. However, before you get too excited about driving one this winter, FCA US spokesperson Ariel Gavilan tells Autoblog: "It is only a concept." Mopar isn't done tuning Dodges for SEMA. The Charger Deep Stage 3 shows what's possible with the company's catalog by packing the Scat Pack 3, strut tower braces, coilover suspension kit, and bigger brakes. Meanwhile, the blacked-out Dart GLH Concept tries to harken back to the style of the famous Omni GLH by fitting a red-accented body kit, including a Mopar Performance aluminum hood. If the standard Ram 1500 Rebel is somehow too subdued, check out the Rebel X (right) in a vibrant shade called Copper. To be ready for anything offroad, it wears some muscular flares to fit 17-inch beadlock wheels and 35-inch Toyo tires. A concept, two-piece front skid plate protects the front. Drivers should also be comfortable no matter where they drive thanks to prototype Katzkin leather seats and a concept air-ride suspension. Chrysler enjoys some mods, as well. The 300 Super S has suave style with Matte Cerulean paint, concept 22-inch wheels, and a grille with little Mopar Ms dotted around it. Performance also sees a boost with a tuned engine, bigger brakes, and coilover kit. The gray 200 S Mopar is similarly stylish with a complete body kit, including a conceptual, dual-vented hood. Fiat and Ram's commercial models aren't left out of the SEMA fun, either.

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.
