NHTSA investigating Ram 1500 models for rear differential failure

The National Highway Traffic Safety Administration is investigating Fiat Chrysler Automobiles and its Ram brand following a number of reports regarding the 2005 Dodge Ram 1500 pickup. According to 15 consumer complaints, the trucks' rear differential locked up while in other cases, the driveshaft separated at its connection to the diff.
Nearly half of the reports claim the truck was traveling at or above 50 miles per hour, while two consumers reported that the diff lockup/driveshaft separation sent their pickups into a spin. Most troubling, though, is that consumers reported little to no sound indicating there was a problem with their truck.
We reached out to Ram for additional information, such as how many vehicles may be affected or what equipment might be fitted that could cause the issue. Unfortunately, the company wasn't willing to elaborate on specifics.

Motorweek goes retro with '80s hot hatch shootout

Motorweek's decades of history on television make it the perfect medium to look back into the automotive past and see how things are different now. It recently added old road test videos to its YouTube channel of the Acura NSX and Toyota Supra, as well as the Ferrari F40. For one of its newest flashback clips, Motorweek has exhumed an affordable five-car challenge of 1986's premiere hot hatches.
By today's standards, this is an eclectic field that features fondly remembered classics like the Volkswagen GTI 16-valve and Acura Integra. However, it also throws in some nearly forgotten contenders like the Dodge Colt Turbo and Ford Escort GT. The angular Toyota Corolla FX16 GT-S rounds out the group.
It's fascinating to watch Motorweek run the quintet through the slalom, down the drag strip and on various roads. What's most striking in this clip is the difference in the definition of a performance car between then and now. With its 16-valve, 1.8-liter four-cylinder, the GTI is the burliest of the contenders with 123 horsepower, but it still takes 8.8 seconds to reach 60 miles per hour. By today's standards, that would make it a plain-jane economy car, and not even a particularly quick one.

Dodge Challenger Scat Pack adds power and noise, with a warranty

If you want to go fast, there's certainly nothing wrong with the Dodge Challenger SRT8. With 470 horsepower and 470 pound-feet of torque for 2014, there's certainly not much to complain about. But what if you want something more aftermarket in flavor? There's no shortage of options, but while turning to the tuner world will make your car plenty fast, that extra power won't just shred rear tires, it'll torch your warranty, as well. That's where Dodge's Scat Pack comes in.
With three stages of mods for both the 5.7 and 6.4-liter Hemi V8s Challenger (as well as the 5.7-liter Charger and, soon, the four-pot Dart), the Scat Pack cars give drivers all the power, aggression and noise of a heavily modded aftermarket car while maintaining the piece of mind provided by the Dodge warranty.
Power gets bumped up to 485 horsepower and 475 pound-feet of torque with the 6.4-liter Scat Pack, while the 5.7-liter can provide up to 58 hp and 47 lb-ft of torque to add to the stock engine's 375 horsepower and 410 pound-feet. It's the latter engine that can really get some work done, with upgrades ranging from the mundane - intake and exhaust - to the racy, like the ported heads and high-flow headers.
