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 recalls 90,736 vehicles due to engine valve issue

Ford will recall 90,736 vehicles as engine intake valves in the vehicles may break while driving, the National Highway Traffic Safety Administration (NHTSA) said on Saturday. The recall impacts certain 2021-2022 Bronco, F-150, Edge, Explorer, Lincoln Nautilus, and Lincoln Aviator vehicles equipped with either a 2.7L or 3.0L Nano EcoBoost engine, the NHTSA said. According to documents posted by NHTSA and sourced from the automaker, "The engine intake valves may break while driving, which can result in engine failure and a loss of drive power." Following an investigation that started in January, 2022, Ford found 22 instances where "the engine intake valves fractured and fell into the combustion chamber of the engine causing catastrophic engine damage." The automaker's analysis continues: "Ford identified that the potential root cause of the failures was engine intake valve failure due to valves that exceeded the designed specification for hardness, were brittle, and more likely to fracture. Ford determined that this was due to the supplier’s grinding processes and the sensitivity of the intake valve material to grinding processes that were not within control specifications. The intake valve material was changed for vehicles produced after October 31, 2021." Fixing the problem will require replacement of the entire engine. "Dealers will inspect each vehicle to determine its cumulative number of engine cycles. For vehicles that do not meet the engine cycle threshold, dealers will accumulate high revolutions per minute (rpm) engine cycles per a service procedure. Engines will be replaced on vehicles that do not pass the engine cycle accumulation," Ford says.

Ford C-Max spied with fresh updates

The Ford C-Max hatchback looks to be getting a few cosmetic updates, as evidenced in this latest set of spy photos. Like the smaller Focus, which also received a nip/tuck for the 2015 model year, the C-Max appears to be getting a revised front fascia with slimmer headlamps and a more, shall we say, Aston Martin-like grille. Around back, there looks to be a new bumper with redesigned taillamps, as well.
In other markets, the C-Max people-mover is available with a range of powertrains, but here in the US, it exists either as a traditional gas-electric or plug-in hybrid. The C-Max's fuel economy has been a particular topic of interest lately, with its official fuel economy ratings having been lowered twice since the vehicle's launch. Sales initially suffered a bit following this fiasco, though numbers have since leveled out. It's unclear if Ford is working on any powertrain tweaks for the updated C-Max seen here, however.
Ford has likely spruced up the hatch's interior, as well, though we don't have photos of that at this time. Mum's the word on when we'll see the new C-Max, but our best guess is that it'll arrive sometime in the next year.
