Mopar rolls out new Scat Packages for Dodge Challenger, Charger and Dart

Dodge buyers looking for that extra performance edge, take note: Mopar is bringing back the Scat Pack. Announced at the SEMA Show in Las Vegas today, the new Scat Packages will be available in three stages for the Challenger, Charger and Dart starting next spring.
Upgrades for the Charger and Challenger equipped with the 5.7-liter Hemi V8 engine include a
new cold-air intake and cat-back exhaust, as well as a remapped ECU. Upgrade to the Scat Package 2 and you get a new camshaft, and the Scat Package 3 tosses in ported and polished heads and hi-flow headers. Upgrades for the Dart GT with the smaller 2.4-liter, four-cylinder Tigershark engine with six-speed manual transmission start with a cold-air intake, short-throw shifter and upgraded brakes. The second stage kicks in a remapped ECU and cat-back exhaust, while the Scat Package 3 for the Dart gives you even bigger brakes, an adjustable suspension and sway bars front and rear.

FCA and Cummins named in diesel emissions class-action lawsuit

Chrysler is now the first United States-based carmaker to be sued for allegedly skewing emissions results. In a move that sounds eerily similar to the troubles of European manufacturers, Chrysler is claimed to have hid diesel engine characteristics causing emissions as much as 14 times higher than permitted by regulations. According to Bloomberg, the lawsuit alleges that Chrysler, together with its diesel engine partner Cummins, has concealed the nitrogen oxide output of certain Ram vehicles produced between 2007 and 2012. The NOx pollutants were meant to be broken down in a process called regeneration in the truck's NAC system, or NOx Absorption Catalyst, which predated the 2013-introduced SCR, or Selective Catalytic Reduction system. By design, the NAC captures and stores NOx emissions, converting them to nitrogen and oxygen through a catalytic process. The lawsuit claims the Cummins engine's system has a limited capacity to store the emissions, and as a result the pollutants escape, increasing emissions, worsening fuel consumption and wearing down the catalytic converter. The later, cleaner SCR system uses a urea-water injection, and it gradually replaced the NAC on Cummins 6.7-liter engines, as it was first implemented in 2011 and made standard in 2013. As Bloomberg notes, the model years of Ram trucks involved in the lawsuit predate the earliest Volkswagen "Dieselgate" models by two years. The lawsuit, filed on behalf of 500,000 truck owners, accuses Chrysler and Cummins of fraud, false advertising and racketeering. As an underlying motive, the filing mentions a 2001 change in EPA emissions standards. Announced to become effective in 2010, the EPA requirements drove Chrysler and Cummins to try and reach those already by 2007. However, the NAC system is said to have fallen short of these goals, and the filing claims that Chrysler and Cummins chose to "rig" the engines instead. The affected vehicles predate the 2014 merger of Chrysler and Fiat. FCA US has released a statement regarding the lawsuit, saying it will contest the lawsuit "vigorously".

Dodge CEO and Gas Monkey Garage dissect the 10-second Challenger Hellcat

So far, whenever we've seen the 2015 Dodge Challenger SRT with its 707-horsepower, supercharged Hellcat V8, the muscle car has been smoking its tires. Dodge is finally proving that the SRT can do more than ruin perfectly good sets of rubber, though. In it's latest video, company CEO Tim Kuniskis hands the Hellcat off to the guys from Gas Monkey Garage to show how quickly the automaker's most powerful model can make it down the drag strip.
Of course, the only fitting contender to race against Dodge's latest top muscle car is its grandpa - a Hemi-powered 1971 Challenger, in this case. Before getting to the main event, the hosts also show off some of the SRT's unique features like the blanks in the grille that feed the intercoolers. We'll go ahead and spoil that the Hellcat makes its pass in the 10-second range, and the video admits the tires on the production version would take just a touch longer to cover the quarter-mile. However, you have to watch film to see just how quick it actually goes. Scroll down to see a classic example of American muscle drag racing against its modern legacy.
