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.

The Dodge Demon's massive torque wrinkles its massive tires

Horsepower doesn't mean a damn thing if a car can't properly put the power down. That's why Dodge has fitted the upcoming Demon with some of the stickiest road-legal rubber available. Those Demon-branded Nitto NT05R drag radials skirt by regulations with just the smallest of margins, and in order to maximize the potential of the 315/40R 18 size tires Dodge increased the car's torque multiplication with a higher stall speed for the torque converter and a 3.09 rear axle. The 12.6-inch-wide tires are fitted to 18x11-inch wheels at all four corners, and they're fatter than those 305-section front tires on the Camaro Z/28 that we raved about years ago. Dodge says the combination of soft, gooey rubber and the new gear ratio gives the Demon about a 15 percent larger tire contact patch, more than twice as much grip, and roughly an 18 percent increase in both converter torque and rear-axle torque multiplication. Simply put, the Dodge Demon moves. You can see the results in the teaser video above, which is titles "Multiplication" and shows the crazy wrinkling of the sidewall that results from putting that torque to the road. We wouldn't be surprised if the inner rim of the wheel needs some grip to keep the tire seated, something Chevy had to do on the last Z/28. There is something wonderful about Dodge's approach to performance cars. While the Ford Mustang and Chevrolet Camaro have moved on from their muscle car upbringings with proper track-focused models, Dodge has stayed true to its roots by developing a machine that's sole intent is traveling a quarter-mile quicker than anything else on the road. Twisty roads may be fun, but there is something wholly and deeply satisfying about going deep into the accelerator with a comical amount of power at your disposal. We can't wait.

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".
