2017 Ford F-150 Raptor desert testing heats up

In case there was any doubt, Ford is taking the development of the second-generation SVT Raptor very, very seriously. The Blue Oval recently completed over 1,000 miles of testing in the boiling heat of the American southwest. Apparently, that mileage was accrued over a 66-mile route designed to mimic the torturous terrain encountered by racers in the Baja 1,000 off-road race. The prototypes, which were built from a mix of existing and next-gen Raptor components, were tested with "fast sandy washes, deep-rutted silt beds, steep climbs in deep sand, and slow meticulous crawls through tight trenches." Ford claims the new truck managed to run the circuit 25-percent faster than the current F-150 SVT Raptor, averaging 50 miles per hour while going as fast as 100 mph in stretches. That said, Dearborn didn't release any dedicated times, so it's unclear just how quickly the 66-mile stage was completed. We do know that durability was a big part of the testing. Ford claims each lap was completed by what sounds like a pretty significant jump, with the trucks ascending a steep ramp onto a two-foot plateau and then completing a step-down to level ground. We have to take Ford at its word here, though. "Steep" can mean any number of things, and we've no idea just how fast the trucks were hitting the ramp or how much air they got. Hopefully, the jumps were aggressive enough to prevent future frame issues. Still, Ford boasting about how rough the Raptor's testing is can be taken as a positive sign for fans of the next-generation of SVT's rugged pickup. NEW F-150 RAPTOR WRAPS UP INITIAL DESERT DURABILITY TESTING DEARBORN, Mich., July 7, 2015 – The 2017 F-150 Raptor – Ford's toughest, smartest, most capable off-road truck ever – recently completed more than 1,000 miles of testing in the southwestern United States. Over 1,028 miles of desert trail designed to parallel the Baja race course in Mexico, the 66-mile route featured a wide range of surfaces including fast sandy washes, deep-rutted silt beds, steep climbs in deep sand, and slow meticulous crawls through tight trenches. The truck topped speeds of 100 mph in places, slowing to 10 mph in others, for an average speed of approximately 50 mph. The 2017 Raptor is 25 percent faster than the current truck based on lap times. At the end of each lap, the new Raptor completed a tabletop jump consisting of a steep ramp up to a two-foot plateau, then a step-off back to level ground.

2021 Ford Raptor vs Ram TRX Specs Compared

Hopefully by now you've had a chance to read our thorough 2021 Ford F-150 Raptor review. If not, check it out, 'cause you'll find a lot more detail and expertise than normal (for Autoblog or anywhere) thanks to Dan Edmunds' vast engineering and off-roading background. If you want all the dirt on the Raptor, pun intended, that's where to turn. If you just want to gaze at the specs, however, and wonder how they compare to the old Raptor or to the Ram TRX, check out the chart below. There you will find dimensions, clearances, angles, weights, capacities, engine output and fuel economy for the 2021 Raptor with both 35-inch and 37-inch tires. As Dan explains in his first drive, there's actually more going on there than just tire sizes. You'll find the same specs for the outgoing second-generation Raptor plus the 2021 Ram 1500 TRX and the less extreme Ram Rebel trim level in the chart, too.  Other reviews and deep dives about the F-150 and TRX 2021 Ram 1500 TRX First Drive Review Our review of the Raptor's chief competitor, the mighty TRX.

NHTSA closes Ford F-150 EcoBoost acceleration probe

Typically when we report on the findings of an investigation from the National Highway Traffic Safety Administration, it's because the government body has discovered a safety issue and prescribed a recall. In this case, however, NHTSA has closed an investigation into a reported performance deficit without ever getting to the recall stage.
The issue revolves around the Ford F-150 - specifically those equipped with the 3.5-liter EcoBoost engine - of which some 360,000 were built in the 2011, 2012 and 2013 model years. After receiving an initial 95 complaints, NHTSA opened an investigation last May - almost a year ago - into the reported issue of reduced engine power under hard acceleration. The agency has since received a total of 525 such complaints, and Ford itself reported receiving over 4,000.
Together, NHTSA and Ford determined that the problem resulted from cylinders misfiring, an issue itself stemming from water getting into the charge air cooler (CAC) mated to the turbochargers. In particularly humid or rainy conditions, water was found to get into the CAC, causing some of the cylinders to misfire, which in turn triggered the ECU to disable those cylinders in order to protect the catalytic converter from damage.
