The 2020 Sierra AT4 Comes With Stronger Off-Road Specs, But Can It Beat The Ram Power Wagon In Its Own Yard?

The 2020 Sierra AT4 Comes With Stronger Off-Road Specs, But Can It Beat The Ram Power Wagon In Its Own Yard?

Ram Power Wagon has a worthy competitor in the GMC Sierra AT4

The Ram Power Wagon has proved its mettle as the ultimate off-road truck many times before. However, there’s another contender – an unlikely one, too - that has the potential to give it a run for its money: meet the GMC Sierra AT4.

The GMC Sierra, despite its intimidating size and structure, is known for its luxuriousness and towing prowess. But the folks at TFL decided to pit the two against each other to see how the underdog performs out of its comfort zone. Do you think the Sierra AT4 can take down the Ram Power Wagon?

Consumer Reports Rips the 2018 GMC Terrain to Shreds in its Latest Review

Consumer Reports Rips the 2018 GMC Terrain to Shreds in its Latest Review

We haven’t seen a beatdown this bad since Goldberg squashed Brock Lesnar in 2016

Consumer Reports does not like the new GMC Terrain. Actually, that might be an understatement of its own because the publication just laid the smackdown on the new Terrain, squashing the SUV in one of the most damning video reviews we’ve seen in a while. There was a lot said in the space of three minutes, and almost all of them were criticisms of the Terrain. It may only be an opinion of one man — in this case, Autos Editor Mike Quincy — but the beatdown isn’t going to make the Terrain look any better in the eyes of consumers.

2017 GMC Acadia Denali – Driven

2017 GMC Acadia Denali – Driven

Bigger isn’t always better

The GMC Acadia has been around since 2007 and shared its Lambda platform, powertrain, and nearly everything else besides its cosmetics with the Chevrolet Traverse and Buick Enclave. These three-row crossovers were the answer for folks wanting a less-expensive, slightly more efficient version of the Chevy Tahoe and GMC Yukon. But the Acadia is leaving the Lambda trio for the 2017 model year with an all-new platform wrapped in a slightly smaller package. It still boasts three rows and seating for seven, but it no longer directly competes with GM’s body-on-frame SUVs in shear size.

The Acadia offers a reasonable staring price around $29,000 for the budget conscious or fleet buyer. But, of course, GMC offers its insanely popular Denali trim, pulling the Acadia from mommy-mobile to high-end luxury cruiser. Its chrome grille and 20-inch wheels wouldn’t look misplaced if valet parked up front. Obviously the price sees a considerable jump, too.

I recently spent a week behind the wheel of the Acadia Denali. My tester came loaded with AWD, GMC’s Dual Skyscape sunroof, adaptive cruise control, automatic collision preparation, and the continuously variable real-time damping suspension. Pricing broke the $50,000 ceiling, but in modern times when vehicle pricing is getting extravagant, this loaded-out tester somehow seems justifiable. Find out how below.

2016 GMC Yukon XL Denali – Driven

2016 GMC Yukon XL Denali – Driven

Corvette power, Suburban size, & Cadillac posh for $10k less than the Escalade

The Yukon XL name has only been around for a relatively short time, having been introduced in 2000, but the long-wheelbase GMC is tied to one of the longest running nameplates in automotive history – the Suburban. Introduced in 1935, the Chevrolet Suburban has generated generations of fans and loyal customers. Now in the modern era, the Suburban has moved from a workaholic carryall to an upper-class status symbol. The GMC Yukon XL takes this to the next level with a more luxurious appearance and nicer interior trimmings. Then there’s the Denali trim.

The Denali lineup within the GMC brand has exploded in popularity with the rebounding economy. These leather-lined, chrome-clad versions of GMC’s vehicles offer Cadillac-like luxury with less shocking price tags. And that’s exactly how to describe the 2016 GMC Yukon XL Denali. It’s a Cadillac Escalade without the distinctive grille, higher price tag, and social clout that comes with owning a ‘Slade.

Nevertheless, the Yukon XL Denali provides all the right equipment and luxury for those seeking Cadillac comfort without the rock star vibe that follows the Escalade. Recently, I spent a week getting to know the Yukon XL Denali – all 18.6 feet of it. Make no mistake, it’s big; but it’s also powerful thanks to a 6.2-liter V-8 borrowed from the Corvette. Yep, this bad boy rocks the LT1 small block. Curious yet? You should be. Keep on reading to see what life is like with the Yukon XL Denali.

2016 GMC Canyon Duramax – Driven

2016 GMC Canyon Duramax – Driven

When you need torque and fuel economy

General Motors wasted no time in announcing its plans to bring a compact turbodiesel to the GMC Canyon and Chevrolet Colorado midsize pickups. In fact, the all three engine options were announced back in 2014 ahead of the 2015 model year launch. Sadly we had to wait until the 2016 model year before the 2.8-liter Duramax four-cylinder turbodiesel became available. Well, the wait is finally over and we’re gotten out chance behind the wheel.

The Duramax is slotted as the Canyon’s range-topping engine. And while it does carry a $3,730 premium over the 3.6-liter gasoline V-6, the turbodiesel offers impressive fuel economy, outstanding towing abilities, and surprising everyday livability. To say it’s a well-rounded engine is an understatement.

Of course, there’s more to the Canyon than just its powerplant. The large chrome grille, LED-encrusted headlights, utility-minded cargo bed, helpful step bumpers, and overall handsome looks are still present, though everything is carried over from 2015. The truck still looks fresh in its second year, and should continue looking so for several more years.

Inside, the Canyon’s cabin is a leather-lined paradise for hard-working folks. It’s also a usable space for the average family, too. The rear bench fits two comfortably, three in a pinch, and folds in two different directions to accommodate different cargo. GMC’s IntelliLink infotainment system software ranks high in user friendliness, while the gauge cluster looks somewhat dull. Nevertheless, the Canyon is a very strong competitor in its class. Let’s have a look.

USA Wins SEMA Middle East's 1st Annual Engine Build-Off

USA Wins SEMA Middle East’s 1st Annual Engine Build-Off

Redline Motorsports, a Florida based performance shop, just took home the top honors in SEMA’s first international engine building competition. The build-off pitted the Redline team against one of the best-known performance shops in the U.A.E.

Both competitors were selected to compete due to their extensive experience with tuning General Motors’ LS engines – the modern small-block V-8 that powers everything from trucks and vans to Corvettes and Cadillacs.

So the competition went down like this: whoever could build and tune the engine with the highest average horsepower over 10 dyno pulls won. Simple enough. Both teams received identical sets of parts, including new LS3 blocks bored out to 416 cubic inches, performance rotating assemblies, and ported LS3 heads; keeping the playing field level. Separating the teams were their choice of three available camshafts and how they tuned their ECUs.

The competitors were also handed the keys to nearly identical 2012 and 2013 GMC Sierra trucks. The single cab, short bed, 4WD Sierras were both fitted with the stock 6L80E transmission and 3.73 gears. With all the parts in place, the competition rolled into day one. Keep reading below

GMC Denali By Hennessey Goes From 0 To 60 mph In 4.5 Seconds: Video

GMC Denali By Hennessey Goes From 0 To 60 mph In 4.5 Seconds: Video

Leave it to John Hennessey to throw a supercharger and a tune on every V-8-powered GM vehicle. Take this 2015 GMC Yukon Denali. It’s 6.2-liter EcoTec3 V-8 is fitted with Hennessey’s HPE650 Supercharger kit that brings the engine’s output rating to — like the name suggests — 650 horsepower.

The blower is a 2.9-liter unit that is cooled by a high-flow intercooler system, while a set of high-flow cylinder heads help the engine breath. A new camshaft makes adjusts the valves’ operation, adding not only more horses but also a respectable rumble. Lastly Hennessey flashes the Yukon’s ECU with a custom tune. Best of all, the whole deal comes with a 3-year/36,000-mile warranty.

The 650 horsepower and 658 pound-feet of torque is a marked improvement from the engine’s stock 420 horses and 460 pound-feet. That helps the heavy, six-passenger SUV to hit 60 mph in just 4.5 seconds. That’s as fast as a 2015 Mustang GT. The Denali continues rocketing down the strip, finishing the quarter mile in 13.1 seconds at 110 mph. Again, that’s darn close to the Mustang’s 13.0-second, 113-mph run.

Want this sort of power in your new $63,000 mall crawler? Sure you do. All it takes is money. Expect to play close to $20,000 for the HPE650 package.

The 2015 Truck of Texas Competition Preview

The 2015 Truck of Texas Competition Preview

Not much goes together quite like Texas and trucks. It’s the U.S.’ largest truck market by a long shot and it’s plain to see as you peruse any given parking lot. Texans love their trucks. That’s why the Texas Auto Writers Association crowns a Truck of Texas winner every year after an extensive evaluation process.

As a member of TAWA, I spent the better part of a week in the dusty hills outside San Antonio testing 75 contenders vying for the prized top spot. Eighteen automakers from around the world were in attendance, the majority bringing more than a handful of vehicles.

Ground zero for testing was the famed Knibbe Ranch, with hundreds of acres of sprawling across the Lonestar state. Muddy creek crossings and rocky hill climbs, combined with twisty country roads and newly paved highways provided the test beds. Those trucks, SUVs and crossovers brave enough to tackle the off-road section were subjected to rock-strewn dirt roads that punished suspension parts and underbody skidplates. More road-biased crossovers were thrown around narrow roads and up steep hills. The new pavement along the Texas highway was still covered in loose asphalt with orange caution cones proving a tempting (yet highly illegal) slalom course. Thankfully no one attempted that obstacle.

The 60 journalists judging the event had a huge decision to make. What truck, SUV or crossover would be crowned the Truck of Texas? Well, you’ll just have to stay tuned to find out. We’ll announce the top winner and the winners of sub-categories on Wednesday.

2015 GMC Yukon Denali - Driven

2015 GMC Yukon Denali - Driven

TheGMC Yukon traces its roots back to 1992 when GMC took the Jimmy nameplate from its full-size SUVs and gave it to its midsize, Chevy Blazer counterpart. Since then, the GMC Yukon and Chevy Tahoe twins have been topping sales charts year after year. In 1999, GMC launched the Denali trim line as an answer to the Lincoln Navigator. Over the years, the Yukon Denali has continued with good success as a stepping-stone between the regular Yukon and the all-out luxury Cadillac Escalade.

I got to spend a week behind the wheel of the all-new 2015 GMC Yukon Denali, and boy is it a sweet ride. Chrome accents, 22-inch chrome wheels, metallic white paint, and HID and LED lighting make this Yukon a standout. With the Denali trim comes a bevy of standard upgrades, including the powerful 6.2-liter, EcoTec3 V-8, Magnetic Ride Control, and power-everything inside the leather-lined cabin.

Though it’s on the pricy side, the Yukon proved to be a capable rig with room for seven and plenty of posh to go around. Head past the jump for the video review, photo gallery, and full review.
