Torque time | 2017 GMC Sierra HD First Drive

It's not the truck that counts, it's how you use it. It's the heavy stuff you fit in its bed or the extremely heavy stuff that gets hooked up to the tow hitch. The ATV, the Jet Skis, the trailer with more square footage than a Greenwich Village apartment. Perhaps you need to get Seabiscuit or, uh, Mr. Ed to wherever they need to gallop next. In our case, there's a pair of very serious-looking snowmobiles perched atop the bed of a GMC Sierra. They spread out as wide as the extended tow mirrors, and their back halves are dangling precariously beyond the truck. Sterling Archer would be giddy; I'm a little nervous. But only because canyon roads and wide vehicles with a high center of gravity go together like peas and custard. The added weight is no sweat at all. That's because this is the 2017 GMC Sierra HD Denali, a truck with the sort of enhanced power, torque, suspension, and stopping capability expected of a heavy-duty pickup. And for this year, the power and torque get a serious bump courtesy of a new 6.6-liter Duramax turbodiesel engine reengineered from almost the ground up with 90 percent new parts. It's quieter and more efficient and it emits less, while most importantly producing 445 horsepower and 910 pound-feet of torque. That's up from 397 and 765, respectively. Chevy fans will note that the same engine is also available in the updated 2017 Silverado HD. Now, for those keeping score at home, that horsepower is best-in-class but the torque number still falls short of the new Ford Super Duty and its Power Stroke diesel V8's 925 lb-ft. Aw shucks. For the record, GM's engineers didn't seem too concerned that they weren't able to eke out an extra 16 torques just to say they're No. 1. "We wanted to first meet emissions and then deliver the maximum horsepower and torque we could, and deliver it over the widest usability range possible," said chief engineer Eric Stanczak. And let's be honest here, 910 pound-feet is herculean, and once again, a jump of 145 lb-ft. Or one Subaru Impreza's worth. Or 110 more than the best Ram can do on a 2500, and its Cummins turbodiesel's 800 pound-feet was eye-popping not too long ago. (The Ram 3500 maxes out at 900 lb-ft with the right transmission.) Ah, but here's the rub. That Cummins-equipped Ram 2500 can still tow more weight according to SAE-compliant measurements – 17,510 pounds for a Ram crew cab with a short bed versus 13,000 in the similar Sierra 2500. The Ford F-250 can manage 15,000.

2017 GMC Acadia coming to Detroit Auto Show

Well, it's about time. If there's one group of vehicles that are in serious need of an update, it's the GM Lambda crossovers. You know, the Chevy Traverse, GMC Acadia, and Buick Enclave. They're super old. Good thing, then, that the brand-new Acadia is coming to the Detroit Auto Show next week, as evidenced by this teaser image found on the company's Facebook page. There's not much to see here, except for an LED taillamp signature on what appears to be a much cleaner rear end. We expect the three-row CUV to feature all of the latest GM tech, including a robust infotainment system with Android Auto and Apple CarPlay. V6 power and optional all-wheel drive makes sense here, too, though we won't rule out some kind of four-cylinder option. When GM launched the Lambda crossovers, the Acadia arrived first in late 2006, alongside the now-discontinued (but still very much present in the current Acadia) Saturn Outlook. The Buick Enclave came next, and the Chevy Traverse arrived after that. It's unclear if GM will stick with this rollout plan, of course, but one thing's for sure: all-new versions of these CUVs cannot come soon enough. Related Video:

Which of these high-powered pickup classics would you choose?

High-performance pickups would appear to be having a moment on the auction site Bring a Trailer, with two tempting examples up for auction right now: a 1971 Ford Ranchero GT and a 1991 GMC Syclone. These trucks are a generation apart, but they each represent the peak muscle truck of their time. The Ranchero, of course, was Ford's car-based pickup, and Ford took advantage of its Torino roots by offering the same ultra-high-performance 429 Cobra Jet V8 in the Ranchero as it did in the Torino-branded coupes and convertibles. The 429 V8 in this truck is said to be numbers-matching, and it looks the business topped with an air scoop poking through the hood. It's paired with a three-speed automatic and a limited slip differential, reportedly one of only 82 1971-model Rancheros with this powertrain combo. As a Ranchero GT, this example sports hidden headlights, and the dual sport mirrors and vinyl top further establish its kinship with its passenger-car siblings. A set of factory Magnum 500 wheels and a respray in the original red add to the muscle-truck vibe. Two decades later, car-based pickups were dead, so when GMC decided to revive the muscle-truck genre it did so with the mid-size Sonoma. The resulting Syclone put a more modern spin on the fast-pickup idea (and on the spelling of "cyclone"). This hi-po hauler uses a 4.3-liter V6 topped with a Mitsubishi turbocharger that helped it make 280 horsepower. It's mated to a floor-shifted four-speed automatic and a Borg-Warner all-wheel-drive system with a 35/65 torque split. The Syclone was a one-year-only model, of which just under 3,000 were built. All were black with matching cloth seats with red accents. The only other '71 Ranchero to appear on BaT was a non-original GT with a 351ci V8 that was a no-sale at $7,900. This Ranchero is already nearly double that figure. Of the four previously Syclones that have crossed BaT's virtual auction block, two have sold, for $36,000 and $50,000, but both had lower miles than this truck. At this writing, these two trucks are neck-and-neck, both in the mid teens with both auctions set to end April 23. Which powerhouse pickup makes you want to put your money down?
