2015-MY CHEVROLET SILVERADO HD PICKUP PICS BELOW







2015-MY GMC SIERA HD PICKUP PICS BELOW

In the same way that Ford's F-Series of trucks includes both the regular full-size F-150 pickup truck range and the bigger Super Duty variants, GM's Chevrolet and GMC brand's offer both standard and larger heavy duty versions of their Silverado and Sierra pickup trucks respectively.

Following on from last year's introduction of the new generation 2014 Chevrolet Silverado and GMC Sierra trucks, today, GM revealed the 2015 Heavy Duty (HD) bodies of the two models, appropriately, at the State Fair of Texas.

As is the case with most common models between the Chevrolet and GMC brands, the Sierra HD is the slightly more luxurious and better looking vehicle of the two, though, most parts are shared. In addition to the regular Sierra HD models, GMC also offers a more distinct looking and even better equipped Denali grade with a unique chrome grille, special interior trim, an 8-inch customizable driver display and more.

Both the Silverado HD and Sierra HD will come as standard with a Vortec 6.0-liter gasoline V8 developing 322HP and 380 lb-ft (515Nm) in the 2500 HD models, and 360HP and 380 lb-ft (515Nm) in the 3500HD bodies, linked to a Hydra-Matic six-speed automatic. A bi-fuel version of the 6.0-liter V8 for operation on gas or compressed natural gas will also be available.

Those looking for more power on either model will find a 6.6-liter Duramax V8 turbo-charged diesel rated for 397HP and 765 lb-ft (1,037Nm) of peak torque paired to an Allison 1000 6-speed auto.

Maximum payload for the 2500HD models is 4,306 pounds (1,953 kg) and for the 3500HD, 7,374 lbs (3,508kg), while maximum conventional trailing, 14,500 lbs (6,577 kg) and 19,600 lbs (8,890 kg) respectively.

Sales of all models in the States will begin in the first quarter of 2014.

It is exactly the same as the old one. New bushings for isolation, but it's just a rebody.

[SVT666]

All the heavy duty pickups look ridiculous, but the GM twins take the cake with their massive square wheel wells that have enough wheel gap to park another Chevy pickup and the ultra low front bumper that looks like it will catch on a parking stop.

[280Z Turbo]

I wish I had an explanation for that ultra low bumper. Either lower the frame or give it good ground clearance.

[Submariner]

Spoiler for better aerodynamics?

[280Z Turbo]

Spoiler for better aerodynamics?

Yes. But why not lower the entire truck?

[Soup DeVille]

Crash specs. For years, raised trucks have legally required lowered bumpers. I'm guessing newer regs are making them lower still.

[SVT666]

Ford and Dodge trucks don't have bumpers that low.

[Gotta-Qik-C7]

Yes. But why not lower the entire truck?

2WD version will be lower....

[Soup DeVille]

Ford and Dodge trucks don't have bumpers that low.

Perhaps GM is being pre-emptive for future regs? Or maybe they're just being GM again?

[SVT666]

Their bumpers have been really low for about two generations now, but this new one is so low it looks ridiculous...especially with the gigantic wheel wells and massive wheel gap.

[Submariner]

Yes. But why not lower the entire truck?

Just speculation.  For example, on the current Yukon/Yukon Hybrid, the hybrid has that same silly looking spoiler while the normal one does not. 

[280Z Turbo]

Billy Bob is gonna get out the sawzall and cut the front spoiler off so he has enough ground clearance to drive over top of dead cows or whatever it is hillbillies do on a farm.

[MrH]

It's for aero purposes guys...

[2o6]

It's for aero purposes guys...

They don't get that. It's easier for them to crack on GM.

[MrH]

+1 pretty much sums up.

[280Z Turbo]

It's for aero purposes guys...

Nobody is debating that. The question is why is the rest of the truck so high?

[S204STi]

Nobody is debating that. The question is why is the rest of the truck so high?

Wat. It's a truck. And the lip can be removed easily by taking off a few clips/screws.

[MrH]

You can't really carry much payload if your suspension has all of 2" of travel...

[SVT666]

I don't care what it's for, it looks stupid.  It's 4" lower than the rest of the truck.

[2o6]

....like the Ford and Dodge ones aren't?

[Soup DeVille]

You can't really carry much payload if your suspension has all of 2" of travel...

Hey, forktrucks don't have any suspension travel at all.

Ride kind of rough though...

[280Z Turbo]

You can't really carry much payload if your suspension has all of 2" of travel...

Uh, I'm thinking it's still pretty high at full compression.

[SVT666]

....like the Ford and Dodge ones aren't?

They aren't.

[Raza]

It's for aero purposes guys...

Are aerodynamics a big concern for full size pickup trucks that are otherwise designed with a ruler?

[280Z Turbo]

Are aerodynamics a big concern for full size pickup trucks that are otherwise designed with a ruler?

Grille size is proportional to manliness. Aerodynamics is secondary to maximizing the size of the grille.

[SVT666]

Look how stupid that bumper looks.

[MrH]

Can't tell if you're joking or not

[Catman]

Look how stupid that bumper looks.

Its just the air damn, calm down.

[Raza]

Can't tell if you're joking or not

Look at the trucks again and tell me if you still think it's a joke. 

Giant, blocky, presumably work trucks.  No one is running these at the Ring.  What's the aerodynamic benefit in real terms?
