The diesel versions of the Chevrolet Colorado/GMC Canyon will be the first to undergo increased scrutiny from the Environmental Protection Agency after the recent Volkswagen scandal turned emissions reporting on its head.

According to Automotive News, a spokesman for GM said the testing could slightly delay the truck’s fourth-quarter release.

“The EPA and CARB told us they are going to do on-road testing,” Chevrolet Trucks assistant chief engineer Scott Yackley told Automotive News.

Farmers are the ultimate craftsman when it comes to small-scale production. The level of management needed to stay competitive and above the high water line is, simply put, astounding. Consolidation in certain areas of agriculture has lead to factory farming, the widespread adoption of automation and genetically modified seeds that keep seed producers competitive. Private farmers are constantly at war with the market and their own budgets.

The agriculture industry has wholly transformed itself over the last 100 years. The automotive industry, which has only really existed for that same period of time, has seen similar levels of change. We are now building more cars, trucks, SUVs, crossovers, trikes and quadracycles than ever before, just like we are growing more food than we’ve ever seen in human history.

But, there’s one major stumbling block ahead — and Sergio Marchionne sees it.

Hydra-Matic 8L90 8-speed automatic

15 city/21 highway/17 combined (EPA Rating, MPG)

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.

2016 Chevrolet Colorado 2.8L Duramax Turbo Diesel

When the 2016 Chevrolet Colorado and GMC Canyon start arriving at dealer lots this fall, they’ll be sporting more than an additional diesel option under the hood. Monroney stickers will be afflicted with much higher prices to the tune of $3,730 more than an equally equipped V-6 model.

However, you will get increased towing capability thanks to a standard towing package, improved fuel efficiency, and a diesel engine brake to minimize wear on brake components.

Next year for General Motors could be defined by a new lower, longer Spark, production starting on the Bolt and a convertible Camaro, according to Automotive News’ facts and factoids department.

The automotive publication posted a speculative timeline of cars that may or may not be in GM’s future, including fuzzy details on a mid-engined Corvette that may or may not happen in or around the year 2020.

In case you’re wondering, we don’t know either.

2015 Chevrolet Silverado

The Chevrolet Silverado has outsold the Ford F-150 so far this year, but sales of Ford’s Super Duty trucks have boosted the company’s truck business past its competition, is reporting.

All three truck makers are selling more pickups than they were a year ago, but flagging F-150 sales and depleted inventory could be keeping Ford’s perennial half-ton leader back.

UAW Wages

The newest round of negotiations between the Big Three automakers and the United Auto Workers will focus on narrowing the gap between veteran workers and “second-tier” workers hired after 2011, Reuters is reporting.

Talks between the UAW, which represents around 138,000 workers, and Ford, Fiat Chrysler Automobiles and General Motors will begin Monday. The UAW’s contract with GM ends Sept. 14.

Union President Dennis Williams said he wanted to focus on narrowing the gap between veteran workers, who make on average $28 an hour, and workers hired post-recession, who make on average $16 to $19 an hour, according to the story.

Sergio Marchionne sent Mary Barra a detailed email in the middle of March in an effort to start merger talks. Barra, CEO of General Motors, was uninterested in the offer and rebuffed Marchionne, CEO of Fiat Chrysler Automobiles.

It was the first time the two executives had ever spoken, but it wouldn’t be the last Barra would hear of Marchionne’s merger desires.

That’s the story being told by the New York Times today, detailing the lengths to which Marchionne is going to trigger consolidation within the automotive industry.

2015 GMC Canyon V6 SLE All Terrain (2 of 18)

Today we are running two reviews of the GMC Canyon at the exact same time – one V6 and one 4-cylinder – for your reading pleasure. If there ever was a time to compare the same truck with different powertrains (and two reviewers with different perspectives), this is it.

The last (and only) truck to grace my driveway in an ownership role – a 2008 Ford Ranger – taught me as much about itself as it did pickups in general. The 3.0-liter Vulcan V6, while durable, was as effective as a donkey pulling a container ship for towing. And just because a truck is rated to tow or haul X pounds certainly doesn’t mean it should. There were also times I would’ve rather had an automatic transmission, like when I inadvertently jumped on Connecticut’s Merritt Parkway. In a snowstorm. With a trailer. 3-4-5-4-5-4-3-4-5. Wipe sweat. 3-4-5-4-5-4-3-4-5.

For better or worse, the Ranger did everything I absolutely needed of it: haul, tow and not throw a rod as I traveled the no-stop, shoulderless freeways over Louisiana swamp.

Creature comforts? Fuhgeddaboudit. Crank windows. No A/C. Not even a CD player.

The new GMC Canyon, with its 3.6-liter V6 engine and semi-plush interior in SLE trim, is nothing like my long departed Ranger. And while it’s logical to compare the Canyon to the Toyota Tacoma and Nissan Frontier on most fronts, it’s more fitting to put it up against the full-size competition on others.
