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:

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!"

GM executive chief EV engineer says reducing cost of plug-in vehicles is 'huge priority'

As we know, another major automaker investing heavily in electrified vehicles is General Motors, and it's doing things much differently than rivals BMW, Ford or Nissan. The Chevrolet Volt extended-range EV is a modest seller at its $35,000 sticker price but a huge hit with owners. The Chevy Spark BEV, still in limited availability, puts smiley faces on its owners and drivers. The just-introduced Cadillac ELR, a sharp-looking, fun-driving $76,000 luxocoupe take on the Volt's EREV mechanicals, has admittedly low sales expectations. With this interesting trio in showrooms and much more in the works, the third vehicle electrification leader I collared for an interview at Detroit's North American International Auto Show (see #1 and #2) was Pam Fletcher, GM's executive chief engineer, Electrified Vehicles. ABG: Why do your EREVs need four-cylinder power to extend their range when BMW's i3 makes do with an optional 650 cc two-banger? "We designed [the Volt and the ELR] to go anywhere, any time" - Pam Fletcher PF: I get that question all the time: why not something smaller? You don't really need that much. You use the electric to its ability, then you just need to limp. But we designed those cars to go anywhere, any time, and we don't want their performance to be compromised. If you're driving through the mountains, we don't want you to be crawling up grades, or to be limited on any terrain. So it's optimized to be able to travel literally the biggest grades and mountain roads around the globe at posted speeds. Because what if you can't? Another good reason: when the engine is on, you have to run it wide open throttle, max speed, most of the time. And while we can do a lot with acoustics, and the ELR has active noise cancelation, a small-displacement, low cylinder-count engine at high speed, high load all the time isn't something you want to live with. That's how we came up with the balance we did among the key factors of performance, NVH [noise, vibration and harshness] and range. ABG: Where you go from here? Is the range-extender engine due for an update? PF: We know and love the current Volt, and there is still a lot of acclaim about it, so we think it's a good recipe. But we are heavily in the midst of engineering the next-generation car, which I think everyone will love and be excited about.
