Fiat Chrysler recalls 4.8 million U.S. vehicles for cruise control defect

WASHINGTON - Fiat Chrysler said on Friday it is recalling 4.8 million U.S. vehicles over a defect that could prevent drivers from deactivating cruise control and warned owners not to use the function until they get software upgrades. The Italian-American automaker said no injuries or crashes are related to the large recall campaign but said it had one report of a driver of a 2017 Dodge Journey rental car unable to deactivate the cruise control. Fiat Chrysler, which in 2015 was hit with penalties from U.S. regulators totaling $175 million for safety lapses, did not say how much the recalls would cost. The recall addresses what Fiat Chrysler called an "extremely rare" series of events that could lead to drivers being unable to cancel cruise control. The National Highway Traffic Safety Administration (NHTSA) said on Friday it "strongly encourages vehicle owners to follow a warning" to stop using cruise control on the recalled vehicles until repaired. NHTSA said drivers could overpower the system by forcefully applying the brakes until the vehicle stopped. Fiat Chrysler also said the vehicle could be stopped by shifting into neutral and braking. Fiat Chrysler shares fell more than 2 percent in premarket trading in New York on the recall. Fiat Chrysler noted that at times cruise control systems automatically initiate acceleration to help vehicles maintain driver-selected speeds, including when going up an incline. If an acceleration occurs simultaneously with a short-circuit in a specific electrical network, a driver could be unable to deactivate the function. Fiat Chrysler said vehicles may be placed in park once stopped, at which point cruise-control is canceled. The recall involves a group of gasoline-powered vehicles with automatic transmissions from various model years built from 2014 through the 2019 model year. Most of the vehicles being recalled cover the 2014-2018 model years. Among the vehicles being recalled are the Chrysler 200, Chrysler 300, Chrysler Pacifica, Dodge Charger, Dodge Challenger, Dodge Journey, Dodge Durango, Jeep Cherokee, Jeep Grand Cherokee, Jeep Wrangler and Ram 1500, 2500 and 3500 pickup trucks and Ram 3500/4500/5500 cab chassis trucks. Fiat Chrysler made the announcement going into the busy Memorial Day weekend, which traditionally kicks off the summer driving season.

2015 Dodge Challenger SRT Hellcat has 707 glorious horsepower [w/video]

Hold onto your butts. "600-plus horsepower" is what we were told to expect from the 2015 Dodge Challenger SRT with its 6.2-liter supercharged Hellcat V8 engine. But as we've just learned, those were incredibly conservative numbers. Dodge has officially announced that the range-topping Challenger will hit the asphalt with 707 - seven hundred and seven - horsepower, making it the "most powerful muscle car ever."
Of course, 707 hp is only part of the story, as the Hellcat has also been confirmed to produce 650 pound-feet of torque. All that power will run exclusively to the rear wheels through an eight-speed automatic transmission that differs from other Challengers. The new gearbox, 8HP90 (rather than the 8HP70) is "upgraded to handle the extra power and torque," says Dan Reid, SRT's manager of product design and motorsports.
We certainly hope you're prepared to spend a ton of money replacing tires.

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!"
