As you may have noticed, automobile sales are picking back up after their seemingly perpetual nosedive of the last two years or so. The same holds true for fullsize pickup trucks, and we're hoping that this resurgence will bring back some of the more interesting developments that had to be shelved due to monetary constraints. Chief amongst these wishes are the unfortunately abandoned light-duty diesel engines from Dodge, Ford and General Motors.

With that in mind, our interest is piqued by a report from our friends at PickupTrucks.com suggesting that the previously shelved 4.5-liter Duramax diesel V8 engine from GM may be back on the table, except with an interesting twist. While the oil-burning powerplant was originally intended just for half ton trucks, GM is reportedly now considering offering the mill in all of its fullsize trucks, including the Heavy Duty models.

General Motors indicates that its 4.5-liter diesel V8 engine is "fully developed and ready" to launch with power ratings of over 310 horsepower and 520 pound-feet of torque. Those figures would just about match what the larger Duramax diesels were putting out about a decade ago and seemingly be plenty for the 2500 class of trucks. What's more, The General told our own Sam Abuelsamid that the still-running fleet of 4.5 diesels is averaging an impressive 25 miles per gallon.

Usually whenever we head out to a new vehicle press launch, we have to sit through exhaustive technical and marketing presentations before we get a chance to climb behind the wheel. However, General Motors put us straight into a dual-rear wheel GMC Sierra 3500 crew-cab diesel upon our arrival in Baltimore. On the docket? A 130-mile trek from Baltimore airport to Rocky Gap Lodge in the Allegheny mountains of western Maryland with Vehicle Line Executive Rick Spina sitting shotgun.

We actually appreciated this 'backwards' approach, because it gave us the opportunity to develop some 'gut' impressions of these new trucks even before we got the attendant sales pitch. For a two-hour, mostly highway jaunt, the duallie SLT proved to be a surprisingly amiable companion, but it was just the first of seven different trucks we would drive over the next couple of days. Read on past the jump find out what GM's new heavy duty trucks are like when sampled in a range of real-world conditions.

The 2011 Chevy Silverado HD didn't pull any punches about wanting to beat the competition, but it might just pull everything else. In case you missed any of its maybe-or-maybe-not best-in-class numbers, The General has put together a nifty little animation for you that trumpets all of its heavy duty points. And it does a much better job of it than the Dude Perfect spot did...

However, since it is well known that size matters a great deal in the world of pickup trucks, you can expect Ford and Dodge to be unveiling bigger trumpets soon enough. Follow the jump to see the Transformer-esuqe spot.

GM announces best-in-class towing, payload figures for heavy-duty Silverado, Sierra

General Motors has just announced the hauling capacities for the 2011 Chevrolet Silverado HD and GMC Sierra HD pickups. The new trucks can now pull up to 21,700 pounds in fifth-wheel configuration and lug around 6,635 pounds worth of payload, thereby making them the new best-in class champions. The traditional tow rating sits at 17,000 pounds. What did GM change to give the trucks their new credentials? The company says that it extensively tested the trucks' systems, including the engine, transmission and brakes at the new gross combined vehicle weight and found that the thing could handle the abuse.

Both the Silverado HD and the Sierra HD now come with tougher bed rails, though. GM specified a new high-strength steel that can take more of a beating compared to last year's pieces. The new tow ratings best the next closest competitor, the 2011 Ford F-350, by 1,000 pounds on the conventional towing front and a more modest 100 pounds under fifth-wheel conditions.

How did we ever live in a world where pickup trucks couldn't tow three Bentley Continental GT coupes and a gooseneck car trailer? Hit the jump for the press release.

GM announces pricing on Chevrolet Silverado and GMC Sierra HD models

Zach Bowman — Fri, 09 Apr 2010 13:01:00 EST

Filed under: Truck, Work, Chevrolet, GM, GMC, Diesel

General Motors has officially announced pricing for the 2011 Chevrolet Silverado HD and the 2011 GMC Sierra HD. Both trucks carry a base MSRP $27,965, though you'll have to tack on an additional $995 destination charge. If you want the 397 horsepower, 765 lb-ft of torque Duramax diesel engine and unstoppable Allison transmission option, GM will politely as you for an additional $8,395. The good news is that despite the powerplant's increase in power and fuel economy, the price has remained unchanged from the 2010 model.

For the first time ever, the "Professional Grade" model will be available with a Denali package. Priced at $45,865 including destination fees, the Sierra Denali HD will feature all of the luxury goodies and flashy trim of its less powerful brethren. Buyers who opt for the Denali package will only find the truck available with a four-wheel drive, four-door configuration.

Both the Chevrolet and GMC now feature a 20,000-pound towing capacity, which should be good enough to pull whatever your little black heart desires. Hit the jump for the press release.

Chicago 2010: Hybrid chassis shows differences between old and new Silverado HD

No, Chevrolet's new Silverado HD will not be available as a hybrid. The hybrid we're talking about is this chassis on display at the Chicago Auto Show that is constructed of both the previous generation and the new 2011 Silverado HD. The combined chassis is split right down the middle and shows just how much the 2011 model has been improved from the previous model.

Starting with the front suspension, the 2011 Silverado HD receives beefier upper and lower control arms along with larger torsion bars and steering gear. The front axle can now handle up to 6,000 pounds of gross weight, which means that every HD model can bear the weight of a snow plow. Moving through the rest of the display, you can see the all new frame that utilizes 11 fully boxed assemblies that make sure of higher strength steel. The result is that the new chassis has five times more torsional strength than it did before and 92 percent better bending resistance.

At the rear, the Silverado HD benefits from a new, larger asymmetrical leaf spring design that offers improved handling and load capabilities. General Motors is quick to point out that the truck's maximum 6,335-pound payload and 20,000-pound towing capacity (using a fifth-wheel hitch) are both better than the Dodge Ram 3500 HD and the Ford F350 Super Duty.

Finally, the Silverado HD has been upgraded with 14-inch brake rotors both front and rear, a heavy-duty trailer hitch and a 36-gallon fuel tank that, when combined with the improved fuel economy, allows for 680 highway miles on a single tank. You can see the differences in detail in the high-res gallery below, or click here for even more details and photos of the 2011 Silverado HD.

Ford turns down Heavy Duty tug of war challenge with GM

Jonny Lieberman — Wed, 27 Jan 2010 16:20:00 EST

Filed under: Detroit Auto Show, Truck, Etc., Work, Ford, GM

Well this is just too bad. As you may recall, Pickuptrucks.com was chatting with Tom Stephens, GM's vice chairman of global product operations, about GM's new heavy duty pickup trucks. Suddenly Stephens said something quite interesting:

"You know what I want to do to prove it? I want to take our truck and Ford's [new Super Duty] and chain them together back-to-back. Then I want to have them pull against each other. I know our truck will beat theirs."

How cool would that have been? Supremely cool. However, Ford chooses to think different. Via twitter, Ford was asked by a Pickuptrucks.com reader if they'd accept the challenge. Ford said, "We typically don't respond to challenges. We let the vehicles speak for themselves." Ford ended their statement with this link illustrating that the Ford F Series has been America's best selling vehicle for 33 years straight. As we used to say in 4th grade, "Oooh! Burned!"

Still, we would have really loved to watch a tug of war. Who would have won? Probably a Dodge. On a semi-related note, Pickuptrucks.com's Mike Levine was bragging via Facebook about the Ford SVT Raptor he's driving this week. We asked him if he would like to chain it to the 470-hp Jaguar XF Supercharged we're driving this week and have ourselves a little tug of war. Levine's response, "Only if we do it in mid-air." Touché.

Report: 2011 Chevrolet Silverado HD to debut in Chicago

Jeremy Korzeniewski — Fri, 15 Jan 2010 18:01:00 EST

Filed under: Chicago Auto Show, Truck, Work, Chevrolet, GM, GMC, Diesel

According to our friends over at PickupTrucks.com, Chevrolet will show off the latest iteration of its Heavy Duty pickup truck at the Chicago Auto Show next month. The 2011 Chevy Silverado 2500 and 3500 (2010 model shown above) are expected to be equipped with a new version of the well-regarded 6.6-liter Duramax diesel V8 engine that will almost assuredly use a urea solution to curb nitrogen oxide emissions. General Motors continues to partner with the diesel experts at Isuzu for the Duramax engine.

Under what's sure to be somewhat revised sheetmetal will reportedly be an all-new chassis along with some "other surprises," surmises PickupTrucks.com. We expect a GMC Sierra HD to also be on display, but we can't say for sure. We'll be on hand in Chicago to see how GM reacts to the 2011 Ford Super Duty pickups and their all-new 6.7-liter diesel V8 engine, so stay tuned.

Spy Photos: 2010 Chevy Silverado HD

Dan Roth — Tue, 01 Jul 2008 16:38:00 EST

Filed under: Spy Photos, Truck, Chevrolet, GM

Look quickly, and you'll miss the changes, but GM's got some subtle exterior tweaks in store for its Heavy Duty trucks in 2010. Development doesn't stop even though the practice of using a pickup truck as a commuter car is no longer popular, so GM is plugging away at a new Silverado to avoid being passed up by its competitors.

Competition aside, there's also the issue of federal regulations to comply with, so changes were necessary no matter what. Most noticeably, the bumper changes, gaining a strip of trim that extends across the top, doing away with the overemphasized corner look of the current cow catcher. Looking more closely at the bumper, the air intake in the middle appears to have grown in size. That opening feeds the transmission cooler, so the speculation is that the Allison transmission has picked up extra ratios. Of course, it could just be bigger to gain an edge on thermal management underhood, but we're going to jump on the bandwagon of being excited for more cogs spun by the heavily revised 6.6-liter Duramax diesel with urea injection. That'd be just the thing to tow the Alero.
