A farm, lots of mud thanks to rain from the previous day, and a dose of sunshine to dry out the ground just enough so my feet wouldn’t lose their boots in the slop. This is the perfect location — along with the perfect conditions — to test one of the latest from the pickup crop, the 2015 GMC Sierra.

Or is it?

Under the hood of the SLT-trimmed Sierra sits a V-8 less suited to farm duty and better equipped for automotive trolling.

Before we get into the meat and potatoes of the Sierra, I have a small announcement to make. TTAC now has an off-road area for testing trucks and SUVs. Sort of. It probably won’t be fully available for us for a little while, but shenanigans will be had before the end of the summer. Here’s hoping the automakers send us some metal so we can put it to the test at this newfound playland.

As for this Sierra, well, it isn’t a farm truck. Hell, it’s barely a work truck. The Sierra is available in four different trim levels — base, SLE, SLT and the top-trim Denali. Our SLT-trimmed tester arrived with its bench seat still intact, which is great for mid-summer-romance canoodling and one of the reasons girls dig guys with trucks, maybe.

Interior configuration aside, the real news for this Sierra is under the hood. The 6.2-liter Ecotec3 V-8, with its 420 horsepower and 460 pounds-feet of torque, is a nod to old-school solutions to making power and a pragmatic approach to efficiency. The pushrod V-8 might sound antiquated next to the new turbo and diesel units from Ford and Dodge, but that doesn’t make it any less valid.

  • 1995 SC At least you can still get one. There isn't much for Ford folks to be happy about nowadays, but the existence of the Mustang and the fact that the lessons from back in the 90s when Ford tried to kill it and replace it with the then flavor of the day seem to have been learned (the only lessons they seem to remember) are a win not only for Ford folks but for car people in general. One day my Super Coupe will pop its headgaskets (I know it will...I read it on the Internet). I hope I will still be physically up to dropping the supercharged Terminator Cobra motor into it. in all seriousness, The Mustang is a.win for car guys.
  • Lorenzo Heh. The major powers, military or economic, set up these regulators for the smaller countries - the big guys do what they want, and always have. Are the Chinese that unaware?
  • Lorenzo The original 4-Runner, by its very name, promised something different in the future. What happened?
  • Lorenzo At my age, excitement is dangerous. one thing to note: the older models being displayed are more stylish than their current versions, and the old Subaru Forester looks more utilitarian than the current version. I thought the annual model change was dead.
  • Lorenzo Well, it was never an off-roader, much less a military vehicle, so let the people with too much money play make believe.
