121k Dodge Darts being investigated over braking problem

The National Highway Traffic Safety Administration is investigating the Dodge Dart due to reports of braking problems. Some 121,000 cars are possibly affected, all from the 2013 model year. According to The Detroit News, NHTSA received 18 complaints about the brake pedal becoming hard to depress on these cars, increasing stopping distance. Drivers reported hearing a "pop noise or an air hissing noise when applying the brake pedal, followed by a hard pedal feel and reduced brake effectiveness," NHTSA told the News. In a particularly terrifying incident, one driver says the Dart's braking system shut down while driving at 50 miles per hour. "I feared for my life. It is one of the scariest things I have ever dealt with," the complaint said, according to The Detroit News. A Fiat-Chrysler spokesperson said the automaker is "fully cooperating" with this investigation.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"

Tesla Model S P85D shows 707-hp Dodge Challenger Hellcat how to drag race

Street Car Drags hosted a bang-up event at the Palm Beach International Raceway last weekend, with a list of massive horsepower ICE cars going up against one another and a trio of Tesla Model S P85Ds. One of those duels pitted the 691-horsepower Tesla against a 707-horsepower Dodge Challenger SRT Hellcat, and the result was an old-school beatdown and a world record for electric cars. The Model S P85D ran the quarter in 11.6 seconds at 114.6 miles per hour, the new mark for BEVs at the drag strip. Proving its pace, it ran three more times in 11.69, 11.72 and 11.76 seconds. It got from the start line to 60 miles per hour in 3.1 seconds. The Hellcat, well, it wasn't a race, really. It was the Hellcat's driver's first time at a drag strip and his first time trying to launch it, so after an excellent burnout ahead of the lights, he rolled to the line, almost jumped the start, balked at the real start and spun his tires for the first 100 feet down the strip. The theory is that he overheated his street tires during that burnout, and the resulting greasy rubber did what greasy rubber does. By the time he got to the other end 17.46 seconds later the Tesla driver had showered and was enjoying a funnel cake. When things go right, though, Dodge estimates the Hellcat will do 11.2-second runs on street tires and it has been clocked at 10.85 seconds at 126.18 mph on street-legal drag radials. There's video of the not-quite-a-race above, and Drag Times says there'll be a rematch between the two in a couple of weeks.
