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!"

Ford F-150, Chevy Silverado, Toyota Tundra flunk IIHS headlight test

The Insurance Institute for Highway Safety put pickup truck headlights to the test and found that the majority of them were equipped with subpar units. The 2017 Honda Ridgeline was the only truck to earn a rating of "good." The large pickup truck test was comprised of the: 2016 to 2017 GMC Sierra, 2017 Nissan Titan, 2016 Ram 1500, 2016 to 2017 Chevrolet Silverado, 2016 to 2017 Ford F-150, and 2016 to 2017 Toyota Tundra. The Sierra's headlights earned a rating of "acceptable," the headlights found on the Titan and Ram 1500 were found to be "marginal," and the ones on the Silverado, F-150, and Tundra were rated as "poor." IIHS claims the F-150 was the most disappointing out of the large pickup trucks as both its halogen and optional LED headlights failed to provide adequate visibility during testing. The Ridgeline (which earned a "good rating"), is usually considered a midsize or small truck, though IIHS included it in the field of large pickups. The headlights on the 2016 Chevrolet Colorado, 2016 GMC Canyon, 2016 Nissan Frontier, and 2016 to 2017 Toyota Tacoma, which made up the small pickup truck group, all earned a rating of "poor." The IIHS claimed the Colorado had the worst headlights of any truck that was tested, as the base vehicle's units were only able to illuminate up to 123 feet in front of the car. The Ridgeline's headlights, for reference, were able to illuminate up to 358 feet in front of the vehicle. To conduct its test, the IIHS utilizes a special tool to measure how far light is projected out of the headlights in different driving situations. The trucks' headlights were tested in a straight line and in corners, while vehicles with high-beam assist were given extra praise. The headlights on the pickup trucks also mimic the testing that was done on small SUVs and cars earlier this year. Next year, automakers will need to fit their vehicles with headlights that earn a rating of either good or acceptable to earn the IIHS Top Safety Pick+. Related Video:

2020 Ford Explorer, Lincoln Aviator reportedly facing numerous QC issues

A lengthy report in the Detroit Free Press delves into a range of quality control issues confronting the 2020 Ford Explorer and its luxury platform sibling, the 2020 Lincoln Aviator. Freep says it's been following the issue for two months, tapping various unnamed sources for information on the automaker's unorthodox route to resolution. Seems the problem is Explorers and Aviators leaving the production line at the Chicago Assembly Plant with flaws in areas like the chassis, transmission and suspension, said vehicles trucked to Ford's Flat Rock Assembly Plant (FRAP) outside of Detroit for repair. The estimates range from 10,000 to 18,000 vehicles affected, numbers so high that Ford has sought help from Roush Engineering in nearby Allen Park, and brought workers and managers from other plants in the Midwest to FRAP to get vehicles repaired and shipped to dealers. Ford hasn't shared the nature of the problems with anyone outside the company, including dealers and customers. Freep's sources are said to include workers who have provided photos of certain vehicles and of tents used to house parts at the FRAP repair site. The Explorer chassis allegedly has an unidentified problem that engineers are using X-rays to diagnose, and the transmission is having problems sensing when it's in park or going into park. Both the Explorer and Aviator have come off the line with HVAC units that only blow hot air. And the Aviator's height-adjustable suspension enters failure mode for unknown reasons. These come on top of quotidian mishaps common to every new vehicle, but that are meant to be sorted in pre-production, like missing emblems and trim pieces. They also come on top of a recall in early August issued for the Explorer and Aviator concerning the instrument cluster and parking brake, and another at the end of August over rear seatbacks that could collapse in a crash. An automaker spokesperson told Freep, "Making updates to preproduction models based on all-new platforms as they roll off the assembly line – is standard industry practice." Except these aren't pre-production, these are early production vehicles that paying customers and dealers are waiting for, and some of the affected vehicles have been pulled off dealer lots. Dealers say they are fine waiting for the trucks to get sorted out, and they'd rather have Ford fix the problems before the SUVs go to customers.
