Just prior to the annual Army-Navy football game in Philadelphia over the weekend, Motor Trend‘s Editor-in-Chief Angus MacKenzie, presented General Motors CEO Dan Akerson with the coveted truck of the year award, in reference to the 2011 Chevy Silverado HD.

It marks the first time since 1979 that both a GM car and truck garnered MT‘s annual vehicle awards (the Chevy Volt was recently named MT‘s car of the year for 2011).

Introduced last summer the 2011 Silverado HD is highlighted by a new, improved chassis, better suspension and steering, plus a new Duramax diesel engine and Allison transmission. Said MT‘s MacKenzie, “on the outside the 2011 Chevrolet Silverado HD appears to have been given a subtle makeover, but it’s what’s under the skin that makes this truck a winner.”

“With more capability and technology than ever before, we believe the Chevrolet Silverado HD sets the bar for heavy-duty trucks,” said Akerson. “It’s a great honor to have such a respected authority as Motor Trend agree.”

GM has added numerous improvements into its 2011 Chevy Silverado and GMC Sierra Heavy-Duty full-size pickups, but barely a month after production began at the Flint assembly plant, the company recently decided to suspend it in order to trace and repair a defective part.

The exact component remains undisclosed, but three shifts of production were canceled late last week on Thursday/Friday, until the problem was fixed. However, production of the trucks has now resumed. Those pickups that had already been shipped to dealers before the problem was identified will be recalled and the suspect part replaced before final delivery to customers.

After unveiling the new 2011 Silverado HD at the Chicago Auto Show earlier this year, Chevy has now released pricing for the big truck. Standard models will start from $27,965, while those wanting the Duramax diesel and Allison transmission combo will have to spend $36,360 – a jump of $8,395. That price is, however, the exact same number as last year’s model, which is impressive considering the improvements made for the all-new 2011 truck.

The new base Vortec 6.0L V8 makes 360-hp at 5400 rpm and 380 ft-lbs of torque at 4200 rpm. A total of 90 percent of the engines torque is available from 2000 rpm allowing for a 13 percent increase in fifth-wheel towing for a total tow rating of 14,700 lbs. As for the new 6.6-liter Duramax V8, it  is rated at 397-hp at 3000 rpm  and 765 ft-lbs of torque at 1600 rpm. The increase for Chevy is a total of 32-hp and 105 ft-lbs over the previous Duramax. As a result it can tow up to 20,000 lbs and has a payload rating of 6,335 lbs. GM is proud to boast that fuel economy with the new engine has been increased by 11 percent (although not mpg numbers are available), with a total driving distance of 680 miles on a tank.

In addition to the fuel economy improvements, Chevy claims improved acceleration with Duramax/Allison combo, resulting in a 0.3-second improvement to 60 mph and a 0.5-second improvement in the quarter-mile for a rating of less than 9 and less than 16 seconds respectively.

A new front suspension with forged steel upper control arms and cast iron lower control arms is also a part of the 2011 package with the new front independent suspension now delivering a 25 percent improved front axle weight rating. The new 6,000 lb rating now means a snow plow can be used on all 4WD cab models equipped with the snow plow prep package. In addition, rather than a single torsion bar like on the previous model, the 2011 gets five different torsion bar rates for five different gross axle weight ratings, allowing height adjustability in accordance with the weight of a snow plow or other accessory.

As for the rear suspension, the leaf springs are now 20 percent wider, helping to improve the truck’s rear gross axle weight rating. Now 2500 models are rated to 6,200 lbs, while 3500 models get a 7,050 rating for single wheel or 9,375 of dualies. The new rear suspension is also designed to reduce wheel hop.

Safety equipment includes StabiliTrak and Trailer Sway Control on all single-rear-wheel models as well as a new Hill Start Assist feature, that holds the truck for 1.5 seconds when leaving a stop on a hill. Chevy also says that under heavy load it has reduced noise vibration and harshness (NVH) by as much as 30 percent.

With Ford announcing its F-Series Super Duty power, payload and towing capabilities just a few weeks ago, Chevrolet has responded with some big numbers for the all-new 2011 Chevy Silverado HD. The new 6.6-liter Duramax V8 is rated at 397-hp at 3000 rpm  and 765 ft-lbs of torque at 1600 rpm. This tops the F-Series Super Duty that’s rated at 390-hp at 2800 rpm and 735 ft-lbs of torque at 1600 rpm. The increase for Chevy is a total of 32-h and 105 ft-lbs over the previous Duramax.

Those numbers don’t tell the whole story, however, as the new truck still follows behind the Ford in payload and towing capability. The new Duramax Silverado HD can tow up to 20,000 lbs and has a payload rating of 6,335 lbs. The F-Series Super Duty is rated at 21,600 lbs and a payload rating of 6,520 lbs.

GM is proud to boast that fuel economy with the new engine has been increased by 11 percent (although not mpg numbers are available), with a total driving distance of 680 miles on a tank.

As for the new base Vortec 6.0L V8, it gets 360-hp at 5400 rpm and 380 ft-lbs of torque at 4200 rpm. A total of 90 percent of the engines torque is available from 2000 rpm allowing for a 13 percent increase in fifth-wheel towing for a total tow rating of 14,700 lbs.

Chevy chose the Chicago Auto Show to debut its all-new 2011 Silverado Heavy Duty pickup truck with more power and capability. New Silverado HD models sit on new frames and come with an optional all-new 6.6-liter Duramax V8 and Allison 1000 six-speed transmission. The truck’s base tow rating is now 16,000 lbs, while a 3500 crew cab/long box can pull up to 20,000 lbs. For the record, that’s 2,400 lbs more than the RAM 3500 and 1,200 lbs more than the 2010 F-350 – although no 2011 F-350 stats are available. Maximum payload is now 6,335 lbs, well above both the Ford and Dodge, although (again) Ford claims segment-best payload… but that was before the new Silverado HD was unveiled.

With wheelbases ranging from 133.6 inches to 167.7 inches (depending on how you order your truck), along with wider front and rear tracks, the new Silverado HD delivers a smoother ride and better handling.

Chevy hasn’t given any new performance stats on the all-new 6.6-liter Duramax diesel, but has said it expects segment-best torque. The block itself is a carry-over from the past model but the majority of moving engine parts are new, as is the entire fuel system. NOx emissions are also down 63 percent thanks in part to an exhaust after treatment system that is used because it won’t interfere with the engine’s ability to create power. The Diesel Exhaust Fluid (DEF) used in the process does require refilling every 5,000 miles. In addition, the new engine is B20 biodiesel capable.

As for the new Allison transmission it has been strengthened to work with the added torque of the new engine and features an optional exhaust brake, Power Take Off and a Driver Shift Control (DSC). It’s also designed to work with the new Duramax engine to give improved fuel economy by 11 percent and Chevy says to expect a fuel range of 680 miles on the new 36 gallon tank.

In addition to the fuel economy improvements, Chevy claims improved acceleration with Duramax/Allison combo, resulting in a 0.3-second improvement to 60 mph and a 0.5-second improvement in the quarter-mile for a rating of less than 9 and less than 16 seconds respectively.

A new front suspension with forged steel upper control arms and cast iron lower control arms is also a part of the 2011 package with the new front independent suspension now delivering a 25 percent improved front axle weight rating. The new 6,000 lb rating now means a snow plow can be used on all 4WD cab models equipped with the snow plow prep package. In addition, rather than a single torsion bar like on the previous model, the 2011 gets five different torsion bar rates for five different gross axle weight ratings, allowing height adjustability in accordance with the weight of a snow plow or other accessory.

As for the rear suspension, the leaf springs are now 20 percent wider, helping to improve the truck’s rear gross axle weight rating. Now 2500 models are rated to 6,200 lbs, while 3500 models get a 7,050 rating for single wheel or 9,375 of dualies. The new rear suspension is also designed to reduce wheel hop.

We could probably go on forever discussing the upgrades to the new 2011 Silverado HD, so we’ll try and wrap this up with a few more important things you should know. For 2011 the brakes are larger, measuring 14-inches at all four corners while the swept area of the brake pads has been increased with 13 percent more area covered on the front rotors and 17 percent more covered on the rear. Gone are 16-inch wheel fitments, with 17s now the new base wheel, while 20s can be had on the 2500HD. Safety equipment includes StabiliTrak and Trailer Sway Control on all single-rear-wheel models as well as a new Hill Start Assist feature, that holds the truck for 1.5 seconds when leaving a stop on a hill. Chevy also says that under heavy load it has reduced noise vibration and harshness (NVH) by as much as 30 percent.

As for the truck’s new look, well, there’s not much to talk about because there’s not a lot that’s new. With tight budgets at GM as of late, the Silverado HD team was given limited funds to build the truck and so they chose to put the money where those who really need a heavy duty truck will appreciate it most. Aesthetically, the only real changes to the 2011 model are a new chrome bumper, a “power-dome” hood and a revised grille. Expect more significant changes in a few years time.

Finally, let’s not forget the standard engine, a 6.0-liter Vortec V8 and six-speed 6L90 automatic transmission. With no output numbers yet available, Chevy does claim roughly 90 percent of the engines torque will be available from 2000 rpm and that it will allow for a 13 percent increase in fifth-wheel towing for a total tow rating of 14,700 lbs.

Take a look through a gallery below, as well as our additional gallery showing the Silverado HD’s new frame and underpinnings.

2011 Chevy Silverado Heavy Duty Gets More Powerful and Efficient Duramax 6.6 and Allison Tranny

New truck mostly unchanged on the surface, but all-new underneath

The all-new 2011 Chevrolet Silverado Heavy Duty models might not look all that new and there’s a good reason for it. With tight budgets at GM as of late, the Silverado HD team was given limited funds to build the truck and so they chose to put the money where those who really need a heavy duty truck will appreciate it most. Aesthetically, the only real changes to the 2011 model are a new chrome bumper, a “power-dome” hood and a revised grille. Changes to the rest of the truck, however, are significant.

For starters, new Silverado HD models sit on new frames and come with an optional all-new 6.6-liter Duramax V8 and Allison 1000 six-speed transmission. The truck’s base tow rating is now 16,000 lbs, while a 3500 crew cab/long box can pull up to 20,000 lbs. For the record, that’s 2,400 lbs more than the RAM 3500 and 1,200 lbs more than the 2010 F-350 – although no 2011 F-350 stats are available. Maximum payload is now 6,335 lbs, well above both the Ford and Dodge, although (again) Ford claims segment-best payload… but that was before the new Silverado HD was unveiled.

NOx emissions are also down 63 percent thanks in part to an exhaust after treatment system that is used because it won’t interfere with the engine’s ability to create power. The Diesel Exhaust Fluid (DEF) used in the process does require refilling every 5,000 miles. In addition, the new engine is B20 biodiesel capable.

Chevy says the engine has been tested to 200,000 miles under extreme conditions, using what the engineers refer to as a “95th percentile” customer.

As for the new Allison transmission it has been strengthened to work with the added torque of the new engine and features an optional exhaust brake, Power Take Off and a Driver Shift Control (DSC). It’s also designed to work with the new Duramax engine to give improved fuel economy by 11 percent and Chevy says to expect a fuel range of 680 miles on the new 36 gallon tank.

General Motors’ vice chairman of global product operations is so strong a believer in his company’s product he’s willing to prove it in a tug-of-war between the GMC Heavy Duty and the Ford F-Series Super Duty.

Vice Chairman Tom Stephens made the bold statement in an interview with PickupTrucks.com about the new Duramax engines powering the 2011 Chevrolet and GMC Heavy Duty. The site’s editor was surprised by the statement, he asked Stephens three times if he was serious, but Stephens remained adamant.

“You’re going to love our new diesel Duramax engine in the new Heavy Duty,” Stephens told PickupTrucks.com. “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.”

PickupTrucks.com passed the challenge on to Ford but has yet to get a response. We’re not sure if Ford is willing to take the bait, but this is one challenge we would love to see.

Chevrolet is expected to unveiled the all-new 2011 Silverado 2500 and 3500 Heavy Duty pickups at the Chicago Auto Show in just a few weeks. The same show, just a year ago, is where Dodge launched the new Ram HD line. Later this year, Ford is preparing to introduce its new 6.7-liter Powerstroke-powered F-Series HD.

The truck is expected to ride on an all-new chassis and be powered by a new 6.6-liter Duramax diesel V8 with more power and better emissions. We also expect some more semi-truck styling to keep up with the looks of the competition.
