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.
