Dodge Scat Packages add Mopar performance upgrades in three stages

Dodge has revealed what it calls Scat Package Stage Kits that enhance the performance of the Charger and the Challenger equipped with the 5.7-liter V8, and the Dart equipped with the turbocharged 2.4-liter inline four-cylinder engine. The Scat Packs use Mopar performance parts that also can be bought separately. Most of the upgrades increase engine output, but Dodge somehow manages to not specifically mention the power gains associated with each Scat Pack.
The three Scat Packs offered for the V8-powered cars focus on higher power ratings, and each stage comes complete with a unique engine-management calibration to optimize output. Stage one comes with a cold-air intake and a cat-back exhaust; stage two adds a performance camshaft; and stage three really gives you the goods, adding ported polished cylinder heads and performance headers.
For the Dart, the Scat Packs focus on engine, transmission, chassis and brake upgrades. Stage one will net you a cold-air intake, a short-throw shifter and slotted rotors with performance brake pads; stage two adds a cat-back exhaust system and an engine-management calibration to increase output by taking advantage of premium-octane gasoline; and stage three adds 13-inch vented brake discs up front clamped by four-piston calipers, suspension with adjustable springs and struts and performance front and rear antiroll bars.

NHTSA investigating Chrysler for airbags, ignition switches

Chrysler is being targeted by the National Highway Traffic Safety Administration in a pair of actions that focus on over 1.2 million Jeeps, minivans and crossovers.
The first is a "preliminary investigation" that focuses on an airbag issue afflicting the Jeep Commander built in model years 2006 and 2007 and Grand Cherokee from 2005 to 2006. In total, 700,000 vehicles could potentially be affected. It's not entirely clear what the airbag issue is, with The Detroit Free Press simply stating that the restraint systems in the affected Jeeps may be "faulty."
The other investigation is what's called a "recall query" and it covers a problem that General Motors should be familiar with. In this case, there could be a problem with the ignition switches of 525,000 vehicles, ranging from 2008 to 2010 Chrysler Town & Country and Dodge Grand Caravan minivans, to the 2008 to 2010 Dodge Journey crossover. Again, it's not entirely clear what sort of behavior prompted the 32 complaints that NHTSA has received on these vehicles.
