In case you haven’t noticed, America’s truck wars are in full swing. Now, more than ever, the Detroit Three are gleefully beating each other over the head with a proverbial chair printed with towing and torque figures. Prodigious power? Sure. Enormous cabins? Yewbetcha. Grilles to the moon? They got ya covered, buddy.

Hot on the heels of a half-ton rethink, the crew at Chevrolet turned their attention to the Heavy Duty series of pickups. In a perpetual race with their competition, and the introduction of new engines and no fewer than fifteen camera views, you know this thing is going to haul trailers like a large poutine from Frank’s Diner turns your author’s bloodstream into artery putty.

If we were to have told you a few short years ago that The General would soon be producing mass copies of a rear-drive vehicle powered by a turbocharged straight six diesel, you’d have had us committed to the nearest madhouse. After all, such a bumf reads like sport European sedan from the eighties, when cars were cars and most passengers were terrified.

But it isn’t a sports sedan, nor even a performance coupe. Getting inline at GM these days means moving into a Silverado half-ton pickup truck, the latest entrant from the Detroit Three in a quickly escalating war of diesel supremacy in trucks not competing in the Dreadnought-class. These are the volume trucks, folks, and all of the diesel powertrains — Ford, Chevy, and Ram — displace an identical 3.0L from their six cylinders.

Differences abound between the three, causing your friendly neighborhood gearhead’s mind to temporarily out of control, even more so than it does after his third ration of Lamb’s Rum. Let’s dive in and decipher it all.

While diesel may be deader than disco in the passenger car segment, it is rolling plenty of coal in the half-ton pickup truck class. Once the domain of heavy duty rigs, oil burners are now snaking their way under the hoods of consumer-grade trucks.

We’ve known for a spell the output of Ford’s half-ton PowerStroke, as we have with Ram’s on-again-off-again EcoDiesel. Now we learn GM’s rating and, compared to that pair of competitor mills, it can brag about being best in class.

Earlier this year, Chevy unveiled its new 2019 Silverado and, at the time, made mention that the nameplate would eventually migrate to its commercial line of trucks.

At today’s Work Truck Show in Indianapolis, Chevrolet did indeed unveil its 2019 Silverado in burly 4500HD, 5500HD, and 6500HD formats. It’s the biggest Silverado ever, news that will surely delight groups as diverse as hard-working construction crews and builders of aftermarket bro-dozers.

Suing automakers over diesel emissions violations is quickly on its way to becoming passé.

Since Volkswagen admitted to installing software that circumvented pollution laws, regulators have been on the hunt for their next big target. While it might make their efforts seem like a bit of a witch hunt, there’s good reason to be on the lookout. Studies have shown diesel emission levels are often much higher than analysts expected, with experts attributing the results to the high probability that other automakers are skirting regulatory guidelines — likely by way of defeat devices.

Daimler, Renault, and PSA Group are all being investigated in their home countries as FCA faces legal action within the United States.

General Motors is now being sued for allegedly installing defeat devices in its trucks to sidestep emissions tests, making it the sixth major manufacturer accused of diesel cheating since 2015. However, General Motors isn’t dabbling in gray areas, acting confused, or assuring the public it will get to the bottom of the accusations. It says the claims against it are flat out wrong.  (Read More…)

Sometimes, a manufacturer sees fit to offer its newest ‘you-gotta-try-this’ feature on a range of trims in a particular model. Is it worth getting the most expensive example just to try the new toy? Or should one save their scratch and get the least expensive model? 

With the inclusion of a diesel mill, the 2017 GMC Canyon puts us on par with the rest of the world. Everywhere else, this isn’t a mid-size truck — it’s simply a truck. Only in the land of bald eagles and freedom (or maple syrup and hockey sticks) is this machine considered small – or, at least, smaller. The now horribly mislabeled half-ton class of Rams, Silverados, F-150s, Titans, and Tundras aren’t disappearing anytime soon, but there is a sizable group of buyers who don’t want to pilot a Dreadnought-class battleship around city streets.

Tim reviewed the Canyon Diesel earlier this week, finding it to be a left-field choice that nevertheless ticked many of the right boxes. With that in mind, let’s strip away the options and see if it’s still worth buying.

You want a pickup truck.

You want a small pickup truck.

Unfortunately, such a thing no longer exists, at least not north of the Rio Grande. You’ve migrated your desire to the “midsize” sector, a class in which the Toyota Tacoma, Nissan Frontier, Honda Ridgeline, and two General Motors candidates offer a quintet of possibilities.

Yet a major issue crops up when you begin comparison shopping and discover three full-size issues standing in the way: strong incentives on full-size pickups, full-size truck fuel efficiency comparable to midsize trucks, and full-size capability and interior volume far exceeding that of midsize pickups.

No wonder 85 percent of pickup buyers opt for a full-size truck. Still, 2016 was the best year ever for the Toyota Tacoma and the best year since 2001 for the Nissan Frontier. 2017 is on track to be the Honda Ridgeline’s best year since 2007. The Tacoma has a legendary reputation for toughness. The Frontier is the small-truck traditionalist’s pickup of choice. The Ridgeline is unusual in almost every way.

What unique attribute does GM’s duo manifest? This 2017 GMC Canyon SLE Crew Cab 4×4 has diesel. Diesel fuel in a diesel engine with diesel towing capacity, diesel fuel economy, and a diesel sound owners of decade-old Jetta TDIs will love. (Read More…)

At the end of September, some of my auto journo colleagues busied themselves with the French delights of Paris, covering new reveals at the Paris Auto Show.

Me? I was somewhere much more in line with my personality, surrounded by heavy-duty trucks at the 1.5-mile Texas Motor Speedway. With both Ford and Ram cresting the 900 lb-ft of torque mark, the General needed to play catch-up.

Enter Chevy’s new 6.6-liter Duramax Diesel.

A document containing official horsepower and torque numbers for General Motors’ new 6.6-liter V8 Duramax turbo-diesel was found buried on the GM Powertrain website — before the company quickly deleted it.  (Read More…)

You remember the hood scoop on that teased 2017 GMC Sierra 2500HD? The one General Motors really wanted you to notice?

Well, GM spilled the beans on the mystery inlet, explaining that all of its diesel-powered 2017 heavy-duty pickups will receive the scoop to force-feed air into the 6.6-liter Duramax engine. (Read More…)

After delaying its Chevrolet Colorado/GMC Canyon diesel trucks for a “final validation” issue, General Motors said Tuesday that the trucks would be on their way to dealers.

“The highly anticipated 2016 GMC Canyon diesel has begun shipping to dealers. We look forward to getting these trucks in the hands of our customers and appreciate their patience,” GMC spokeswoman Kelly Wysocki said in a statement.

Earlier this month we reported that people who ordered the truck — in some cases as far back as August — said GM was delaying delivery. A GM spokesman said the trucks were delayed due to a “final validation” issue. GM didn’t specify what the “final validation” issue was with the trucks, nor did they say why they were delayed.

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.

This Duramax-powered 2015 Chevrolet Silverado 2500 HD possesses an as-tested price that’s precisely triple the as-tested price of the 2014 Mazda 3 hatchback I drove around for a week back in late May.

The Mazda had half as many cylinders as the Silverado HD, less than one-third the engine displacement, and no turbocharger. The Silverado has 20% more seating capacity, a wheelbase that’s within eight inches of the Mazda’s overall length, 278% more cargo bed volume than the Mazda has cargo capacity behind the rear seats, and 2.6 times the weight.

The Silverado’s 6.6L turbocharged V8 diesel produces 242 more horsepower while generating more than five times the torque. Yes, it’s not quite three times as heavy as the Mazda, but the Silverado has the torque of five Mazda 3s. Mazda’s 3 operates only as a front-wheel-drive vehicle, but the Silverado can send power to all four wheels. Both utilize a 6-speed automatic transmission. (Read More…)

An I.P.O for a physical product is a refreshing change from the Tech 2.0 bubble we’ve been subjected to lately. Allison Transmission, formerly of General Motors, just issued their first I.P.O, raising $600 million for the company. Allison is now valued at $4.2 billion.
