Jay Leno drives a 1970 Dodge Charger with 1,650 horsepower

When Jay Leno says a vehicle might have too much horsepower, he's got our attention piqued. That's exactly what he thinks about the 1970 Dodge Charger Tantrum from Wisconsin-based SpeedKore Performance. While it still looks like a classic muscle car, the front end now features a carbon fiber hood and fenders. Underneath the lightweight parts, there's a twin-turbo, 9.0-liter Mercury Marine offshore boat racing engine with an astonishing 1,650 horsepower, or an only slightly less asinine 1,350 hp on pump gas. Jay is very mechanically intrigued by the Charger at the beginning of this video, and puts it on the lift to take a look at the underside. The engine plumbing is a thing of beauty, and the mill packs a massive radiator and intercooler to keep things running cool. Leno's drive in the Tantrum is especially interesting. The beastly engine is difficult to control, and anything above half throttle in most gears can spin the rear tires. The significant turbo lag also makes the power unpredictable. When Jay finally finds a straight piece of road, he puts the hammer down and rockets into the distance. And, of course, you know Jay's not going to end the video without some suitably smoking tires.

FCA cuts powertrain warranties to 60k miles

FCA US is cutting back the mileage of its powertrain warranty on some 2016 model year vehicles. Rather than the current five years/100,000 miles of coverage, the new amount is five years/60,000 miles for gasoline-fueled models from Chrysler, Jeep, Dodge and Ram. In March 2015, General Motors made a similar switch to five-years/60,000-miles of coverage for Chevrolet and GMC, and FCA US seems to be citing this as part of the reason for the shift. "Following changes already made by competitors, FCA US is adjusting powertrain warranty coverage for 2016 model year vehicles to be more consistent with industry practices," the automaker said in a portion of its statement. The bumper-to-bumper warranty for these vehicles is unchanged at three years/36,000 miles. According to Automotive News, Fiat's warranty is remaining at four years/50,000 miles. When it changed the mileage limit, GM also halved the number of free service visits for Chevy, GMC, and Buick to two from the previous four. The automaker claimed that the reason for the adjustments to its coverage was that a long warranty was seldom a reason for customers to buy a vehicle.

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".
