PickupTrucks.com's latest test results in a familiar winner [w/video]

PickupTrucks.com has gone and thrown the latest batch of half-ton pickups into a cage match to see who would come out on top. The site put the 2014 Chevrolet Silverado 1500, GMC Sierra 1500, 2013 Ford F-150, Ram 1500, Toyota Tundra and Nissan Titan through a battery of tests. Those included 0-60 miles per hour acceleration, 60-0 mph deceleration, fuel economy, a hill climb, and payload and towing. They even threw the rigs on an autocross course to evaluate overall handling. Each truck was given points based on how it scored in each evaluation.
Who came out on top? Somewhat surprisingly, the 2013 Ford F-150 walked away with the gold, though fewer than 50 points separated first and fourth place. Head over to PickupTrucks.com to read the full evaluation and the final results. You may be shocked to see exactly where some of the segment's newest additions placed. You can also watch a video on the test below.

2018 GMC Yukon Denali gets a sculpted new grille

More than half of all GMC Yukon and Yukon XL models sold wear top-level Denali trim. That's a profitable scenario for the automaker, so, perhaps above all else, GMC needs its premium Denali series of vehicles to continue to stand out in a line of trucks and SUVs at the dealership lot. Hence, chrome, and lots of it. But for 2018, GMC is blessing the behemoth Yukon Denali with an added dose of class with a new multi-dimensional grille. "The new grille, which is flanked by HID headlamps and LED Signature Lighting, advances the design legacy established with the very first Yukon Denali in 1999," said Matt Noone, director of Global GMC Exterior Design. In addition to a sophisticated new look, the grille adds customizable cooling capabilities to the Denali range. Active shutters open when additional cooling is needed, or close to reduce aerodynamic drag when the engine isn't too warm. Further increasing the efficiency of the big brutish 'ute is a new 10-speed automatic transmission. That's two extra gears over the 2017 Yukon Denali, leading to a numerically lower final drive to help save fuel at highway speeds. Inside, Mastique Ash wood trim differentiates the 2018 model from previous years. A 420-horsepower 6.2-liter V8 engine remains standard for 2018, as do blingy 20-inch wheels with 22 inchers optional.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).
