Lincoln, GMC clean up in AutoPacific Vehicle Satisfaction Awards

In recent years, there have been a lot of dire pronouncements made about Lincoln's future, or a lack thereof. But Ford's premium marque is like the Rocky Balboa of the auto business; every time the company seems ready to go, it comes back for more. Apparently, that dogged persistence is paying off, because the industry analysts at AutoPacific have put a big check in their win column with their newly released 2014 model year vehicle satisfaction survey. And despite recent enmity for its seemingly never-ending recall saga, it appears General Motors knows how to satisfy new owners, too.
In fact, not only was Lincoln named as the premium brand with the highest new owner satisfaction, even scored three models on the list of passenger cars with the most gratified buyers - the MKS, MKZ and MKZ Hybrid.
GM's stable of brands was also among the top companies in this year's survey. GMC was named the top popular brand by AutoPacific, with its Sierra pickup and Acadia crossover singled out for awards in their segments. Chevrolet also did incredibly well, with more cars on the list than any other brand. The Corvette, Camaro, Sonic and Impala all made the cut in their respective categories.

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's fullsize SUVs boost highway mileage by nearly 10 percent

We met the redesigned 2015 versions of the Chevrolet Suburban and Tahoe, and the GMC Yukon and Yukon XL at the 2013 LA Auto Show. Improved gas mileage numbers have been announced to go along with the improved exteriors and interiors, with city mileage improving by seven percent and highway mileage going up by nearly ten percent; you'll now get 16 miles per gallon in the city and 23 on the highway.
The only applies to models with the 5.3-liter engine, though, not the premium Yukon Denali and Yukon XL Denali SUVs with the 6.2-liter motor. Still, the 5.3 gets you more power than previously, with 355 horsepower and 383 pound-feet of torque underfoot, on top of the improved fuel economy numbers. The 6.2-liter sticks with official mpg ratings of 15 highway, 21 city. There's a brief press release below with words straight from the horse's mouth.
