2007 Chevy Silverado and GMC Sierra Heavy-Duty Trucks Revealed

Today at the Texas State Fair, GM will debut heavy-duty editions of its all-new 2007 trucks. The 2500HD and 3500HD Chevrolet Silverado and GMC Sierra include dual rear-wheel configurations and both two- and four-wheel drive. They look just as tough on the outside and comfortable on the inside as the base versions introduced earlier this month.

There are three cab styles, regular, extended and crew cab, and three bed lengths, standard, long and dually long. Engine choices include a 6.0-liter V-8 gasoline engine that produces 312 hp and 373 pounds-feet of torque and a 6.6-liter turbo-diesel with 365 hp and 660 pounds-feet of torque. Both engines come with six-speed automatic transmissions.

Maximum towing with the gasoline engine is rated at 13,000 pounds; 16,700 pounds when equipped with a fifth-wheel hitch. Mileage figures weren’t released, but GM says they are “segment leading,” which usually means marginally better than the nearest competitor.

Prices haven’t been announced yet for the heavy-duty trucks, but they should arrive at dealerships in early 2007. While, the truck segment might be shrinking, buyers of heavy-duty variants require the type of towing these vehicles can provide, and we don’t see that need disappearing anytime soon.

awesome looking trucks, though I prefer the GMC over the Chevy

These look even worse than the previous trucks. Almost like a body builder who overdosed on steroids.

Wretched American excess.

Wood trim on the interior?????? How does that fit with the Godzilla exterior?

[tom]

I don't think pictures do these trucks justice. I think once people see these trucks in person they will be blown away.

[Curt]

Check out that new Navigation system now available "really cool"

[Dom Barteau]

This is the worst chevy I have ever seen....I figured they could not get worse than the 2005, but hey look and see!!!!!!!! The GMC does look a little better, just looks like they are trying to copy the Ford F-250 though!!

[Steve]

I think that these new models look better than the current ones.It will do a hell of a lot for General Motors.

[caleb]

The gmc is great but if u would take some crome off the chevy it look awsome especially under the chevy lights. they should make an option to have just the crome grill or have the crome grill and the crome under it but not all the crome under the lights it makes it look very overdone.(if u copy these pics to paint and zoom in and paint the extra crome they look awsome.)

[Greg]

What about a manual 6sp in the diesel? Are they not smart enough to offer that to those of us that like the control of the manual and what about the better fuel economy with the manual. I personnally have an 01 3500 Duramax with the 6sp and love it. Yes it does have some problems, but there are fixes (or at least aftermarket fixes not gm) that can be made. They need to get someone like Eaton Fuller to give them some much need advice and put a manual back into the trucks.

[Steve]

I agree about the chrome and GM shold offer a deisel with the manual trans. I haul scrap and I love the manual.

[Rick]

Seems like the overall opinion an the sites i've visited is not positive on the design of these trucks. I agree, GM squandered an opportunity to take the lead in this segment with these obscure looking veh's. They're better looking than a Tundra but that's not saying much. I had hoped the hype GM made about the Cheyenne at the '03 Detroit show was for real. I saw that truck and it was a home run. But suffice to say, GM seemed to go 180 degrees the other way and spat these creatures out. If sales go luke warm, I wouldn't be surprised if they reskin these things. I don't know who's more ignorant: BMW for allowing Chris Bangle to ruin their cars, or GM to allow some bean counter to lead their "revolution" in style. If they haven't figured it out by now with all their restructuring, it'll never happen.

[Brett]

I've been waiting for the 3500 HD for some time.. I'm disappointed that they have a 13000 GVW.. I was looking forward to at least a 16500 GVW... Overall they are a very nice truck

[Steve]

What happened to the Allison 6 speed auto tranny? Is the 6L90 on the new trucks the Allison with a new designation?

[John]

Allison is for the diesel, hydromatic for the gas

[Angel]

WHAT HAPPENED TO THE CHEVY TRUCKS OF YESTERYEAR? Why all this plastic?? Why do they sit so low to the ground in the FRONT especially? We are Chevy owners, I have a 1995 Tahoe with 215,000 miles, a 2001 GMC Yukon with 128,000 miles (just got that), my husband with a 2005 Chevy 3/4 ton Heavy Duty..well..between the three vehicles..the 1995 Tahoe takes the cake! She's STRONG..climbs out of anything..usually without the help of 4wd! She has pulled the hubby out when he has been stuck. There are no modifications on this truck besides an extra leaf spring on each rear side. As far as I'm concerned..if all auto makers wanted to make real money..go back to the vehicles of yesteryear..where people got 200-300,000 miles easily..where the vehicles LOOKED TOUGH!! I think the past few years for all truck makers has been bad. The hidious things they pop onto the roads these days and call them trucks?!?! Hello!! More like over grown cars! No wonder tree huggers believe we are wasteful when it comes to our unneeded oversized vehicles..these "trucks" aren't made STRONG..they're made PRETTY. Someone needs a MEAN truck..a truck that is boxy and tough..not pretty and weak. I haven't driven the new Chevy's so I can't say what their capabilities are..but I'm willing to bet..my Tahoe at 215K miles has more oomph! I just want a REAL truck to come off the lines again..ahh wouldn't that be nice!

[Sal]

Nice truck, but I think it looks like a for F-250. A Ford with a chevy Suspension. Good combination, but an original idea would have been nice.

[JACK]

No big block? This is a travisty. The 6 liter small block will never cut it. It's diesel for towing or forget about it!

[Jason]

Just thought I would revive the post... The Ford and Dodge trucks are no match for these new GM trucks. The Cummins looks weak when you toss that Duramax in the mix.

[Shane]

All I know is that I have been a chevy fan from ever since i can remember and they keep getting better and better. That is probably why they are the number one best seller and they offer the best comfort in it's class. I look forward to the new line and the oppurtunity to test drive one.

[Chris]

come'on it looks like the F-250 like i mean i know chevys bad and all but im sure they could hace come up with something rather than copying Ford

[matt]

Yes, the GMC looks much better in and out, the Chevy? But all in all it has a duramax and not a powerjoke so that is a big +

[Greg Proffitt]

I am having a mixed thought between the chevy and the gmc. I like the gmc better but have had chevys for years. I have had all others ford dodge gm has now got the best!!

RE: GMC 2500HD/3500HD. The ground clearance looks pathetic. I'm not impressed with the new body style. Unable to see the height of the truck's inner bed wall, the higher the better for real use. Many other noticable dislikes that add up to a big disappointment. They keep delaying the dealer delivery of these... YET THEY ADVERTISE THE HELL OUT OF SOMETHING THEY DO NOT HAVE! WTF? Waste of advertising dollars. 2007 New or 2007 Classic... talk about confusing the consumer AND the dealer when communicating about the Sierra line. If GM/GMC is relying on this truck to keep them out of the red, they may want to rethink and redesign this truck for another year. Who the hell is their target market? Lowrider high school kids?

[scott brown]

what are they trying to prove with that bumber.

[scott brown]

what are they trying to prove with that bumber.

[tommy blackston]

Hate to tell anyone, but pull a full size Nissan up beside this Chevy and except for the front end design there ain't much difference
Ford needs to fire it's car designers and Chevy needs to fire it's pickup desingners and start with a clean slate.

[Chris Pohler]

Lovin the new body style. They look mean.

[pauly]

Wow. That's almost as ugly as the Ford 450. ("almost"...hence "wow." instead of "wow!")

Alright GM. We get the point. Ford and Chrysler have cool muscle cars here/coming, hence a cool retro camaro. Toyota and Nissan have bug-eyed sedans that sell well, hence the new malibu. But come on GM--just because Bill Ford says make it ugly doesn't me you have to...you're smarter than that. How about some original design work.

BTW--the comments about the old trucks having more umph is right--not all of us want our Suburban to feel like a cadillac. The 5.7 Vortec's torque band was great compared to these newer 5.3's I keep out-running and out-towing all the time. Bring back the torque. How about an LS6 version of the 454 displacement range? 450 Horse and 475 ft lbs. That'd be nice for my construction truck.

[THe Boss MAn]

This Truck Kicks AZZ

[mkhammer]

The GMC HD is a better looking truck than the chevy HD in my opinion. It looks like on the chevy front bumper under the head lights the designer didn't know what to do. I call it a design band-aid.
The 07 GMC classic is a much better looking body style, Hurry get one before its to late.

FUEL EFFICIENCY WHAT ABOUT M.P.G.?? w/or w/o 14ft.tandem cargo hauler. Im ready to buy a 2007 loaded GMC drmx dually, I have a small construction co. & Im Tired of my Tired savanahs 3500 also. trading for a set up dually, getting ready for semi-retiredness hitting the road to get away from wis. winters working the south & west regions of the U.S. I want the combo of comfort & balls this truck hopefully will give. Been 30 years since running a dually & 18 since stnd pickup. I NEED FEEDBACK FROM OWNERS ACTUALLY RUNNING THESE before a possible travesty on my part THANKS!!

[Chris]

I have an '06 Duramax 4 door 2500, has 10,000 miles on it, I average 16.5 mpg around town, and have seen 19.6 mpg on an open highway at 65-70 mph. All that is done is a 4 in. cat back exaust. And I love that bad azz Allison 6 speed.

[Dwoodman]

Thanks anyone else?

[Rick]

I agree with Rick Wagoner that Chevy had a grand opportunity to go three notches above the competition with this truck. The problem is after looking at it, I think they settled for one thin notch. First: It has an old four speed tranny that recently made both the Suburban and the new Silverado lose their respective acceleration tests despite their lower curb weights vs. the competition. That is pitiful. Second: Drum brakes? Another poor cost cutting move by GM that won't get by its core buyer base. Third: Nothing on this truck has really broken any technological ground in this segment (see Drum Brakes). Positives: They had to redesgn the interior or they would have lost the battle immediately. Build quality is much improved but the brakes are still too small. Brake feel is improved, a problem that plagued this ambivalent company for decades. However, their small block's power is now lagging behind Ford, Dodge and now Toyota's new OHC mill and real world MPG is below the EPA. despite this being DOD. This brings me to the Cheyenne concept in '03. THAT was the vehicle GM should have built. It would have catapulted Chevy its "three notches" to the top for the next 5-10 years and it was a beautiful truck. Everything about it was cutting edge. In the end, all was typically forgotten. When I look back at this concept, I cannot bring myself to even consider a new '07 purchase. Underneath it all are the usual suspects: The same smallish wheel openings that discourage larger wheel diameters; the lowly 4spd, the low front end, the odd styling, the forgotten manual stick, the evolutionary vs. revolutionary design theme (except interior) all of which leaves me with the feeling that they rushed the '07 to market. Instead, GM is relying on savvy marketing, a gullible buyer and a rebate if the latter two fail. They might not ever "get" it until they are looking up at Toyota as #1. See the link to the Cheyenne's URL and decide.

[Rick]

Response to "Dwoodman:" I owned an '02 Silverado Duramax 2500 (300 HP/520 Ft. Lbs). It could pull anything including my 22ft. car trailer with ease. If you are retiring to the south, you don't need 4wd so you'll save there. I wouldn't bother with a dualie if you are pulling only a 14ft. tandem which leaves the 2500. Mine rode very well, better than the Ford or Dodge and the Duramax was much quieter and proved very reliable. I added a chip and 4" exhaust which just made the truck feel invincible. W/O the dualie, your back will handle the ride when empty. The newer Duramax is 365 HP/ 660 TQ and more refined (quieter) to handle low sulfur diesel. WIth the rack and pinion up front, it will ride and handle even better than my '02 and mine rode like an old Caddy. I'd consider this 2500 as it comes w/a 6spd Allison, where everyone else has a 5spd. Unless you're pulling over 12,000 consistently (like horse trailering or heavy equipment), I'd avoid a dualie in retirement. Hope this helps.

[jyd]

Stunning. Absolutely stunning how ugly this Chevy HD truck is. Who let this out the door? Chevy has made some good looking trucks in the past but this?! At least we know where the designer of the Pontiac Aztek ended up.

This will be a costly mistake for GM. Dodge will gain ground and Ford is in no danger of pushing their best selling pickup streak to at least 32 years.

[Dale R. Schneider]

Hey Rick thanks for input i will consider your advise what about mpg? I do look forward to a possible 30+ft. camper in the next few years &given the drmx life factor considered ???--But i also wonder about future mntnce.6 vs. 4 tires or do 6 have much more life? rear brakes axle pulled on the 3500. 2500 also??? I really dont want to buy again w/ 5yrs.

[Troy]

I actually test drove one last weekend. Nice truck. It does have some shortcomings though. The plastic "cheap" looking interior. The intereior door handles are awkward. They seem to gobble some interior space. On the up side, I was suprised at how refined the ride was for a truck. Engine and road noise was very subdued. Steering felt nice and shifting was smooth from the Auto tranny. Base models were affordable but, I couldn't justify the price for the upper end models that had "added" equipment that's standard on other base line makes and models.

[Andrew Heller]

I think that the big pieces of chrome under the headlights doesn't look the greatest, but overall the truck looks great, but the chevy either needs bigger wheels or bigger tires because the rear wheel wells are so big and it has tiny wheels.

[Rick]

Response to Dale: I forgot to mention that my '02 Duramax was lifted 6" and was running 35" all terrains. I carefully chose the suspension w/Bilsteins and it still rode like an old Caddy regarding a stock Chevy. Chevy's have always ridden better than Ford or Dodge and I tested the '07 and it again raises the bar. The Chevy's independent front end has withstood time and criticism and i'd be hesitant to roll on a solid front axle expecially when by back is old and my patience is thin. My MPG was around 20 HWY w/o chip and tires and still hovered around 17-18 w/chip and a heavy foot. When I towed the numbers were lower but nothing like a gas big block which got some 7-9 MPG loaded. With a 30' trailer I would consider a dualie simply because of the length of it. When it gets that long, the trailer tends to steer the truck even when you have a weight distribution hitch like I was using. The dual wheels help to alleviate this wandering. The downside is when the truck is empty, it will ride hard and be tough to maneuver in parking lots. WIth my Chevy's poor turning radius, I just ran over curbs and a few bushes and parked far from other cars so I could get out easier. I also recommend navigation and a rear camera to help backing up. (I peeled a guys hood that costed me some $800 out of pocket.) I can see no more maintenence with 6 vs. 4 wheels and I never pulled my axles in 69k miles. My original brakes were still good at 69k and with reg. tire rotation (100 lbs each!), the tires wore out at 55k. My motor never burned a drop of oil and was still clean at 4k intervals. The new Duramax is even more efficient than mine and burns the low sulfur diesel so it will be just as reliable with its lower compression despite its higher power. Lastly, the 5 spd. Allison was the best out there and I used the tow/haul mode a lot. It really did a good job slowing the truck but it was sometimes jerky in first gear. The Allison is now a 6spd so it has an extra gear for mileage and stouter lower gears to get the truck moving. No one else has a 6 spd diesel auto.

Hope this helps.

[BCB]

Does anyone know a delivery date for the new HD's. I've been looking out for them, all the web sites say "sometime in the first quarter". Has anyone seen one in person and know an actual release date.
Thanks

[Diesel]

First of all, these 2007 GM/Chevy trucks need something to break-up that thick stupid looking bumper. Perhaps driving lights or cool looking emblem cut-out in the bumper. Maybe the Chevy Bow? I disagree that these trucks look like a Ford 250/350. Besides, larger Fords (F250 & F350) have had the same style since 2000 with the big grille and headlights sucken down below the grille. For those that remember, Dodge was the first to do this in 1997 by copying the big rigs. Personally, I'm tired of that design even though I liked it at first, especially when Ford designed its 2001 F250/350. It's time for something different. The other day I seen a 2005 Sierra SLT that looked awesome because it was lifted about 3 inches. It's amazing how much better a GMC/Chevy truck looks with a little lift. When the Chevy/GMC is lifted it looks better than the run-of-mill Ford style any day!

[Kenny]

I think, they should take all the parts from the GM parts division, spread over a period of 2 series(paneling, interior styles etc) and let consumers 'BUILD' thier own trucks, because it doesn't look like GM knows how to assemble 'trucks' anymore.

I mean, I use my truck (2000 GMC Sierra) I don't go crusing the strip friday night with it. I assemble fences for a living.

My 'custom' would be a 2007 extended cab, regular box GMC 4x4 (3/4tonne) as a base, scratch the hood, grille, fenders. I would use the 2007 Tahoe front clip, with the optional fender flares, to blend with the truck. Then I would take the 2004 GMC black, on charcoal interior fully loaded, and mash the works together. I would then stuff a 5.7L no "frills" V8 from a couple of years ago.

That would be a truck that I would use for a long, long time.
What would be your truck if GM gave you the chance?

[Rick]

I wouldn't hesitate to lay down the money for the cheyenne concept truck from the '03 Detroit show. I saw it up close and felt it was a decade above everthing else. I knew they would never build it because GM NEVER does something that good (it looked production ready) w/o blowing it. It makes the new Silverado seem like a second thought that needed a strong marketing plan to sell it.

[Denny]

The guys that need to tow and don't want a diesel are flat out of luck. Ford and Mopar both have V-10s and GM can't even offer a big V-8. The 6.0 liter small block will never hack it but a lot of folks will buy it based on the tow ratings in the brochures. I been patiently waiting for a redesign (without the slanted eye Asian front end) with the 8.1/496 but I'll just keep my '98 with the 7.4/454. This is just another huge disappointment for a 40 year GM customer. GM has to have unwittenly hired "moles" from other manufacturers because no company would purposely do what they are doing.

[Rick]

Your '98 454 (an old design), smoked a Ford V10 in a comparo a few years ago. The 8.1 is even better (bigger/more power/gas mileage). The 2500/3500 hasn't arrived but as far as I heard, Chevy will offer the 8.1 eventually. I can't blame you for NOT wanting a diesel because the premium for that package is $7200 over a base truck. (my '02 Duramax was $5200 increase). With diesel fuel being 40 cents or more per gallon now, you'd never recoup the money. I bought a '98 2500 (w/350 - 4.10 gears) new in '98 and sold it in '01 when gas got up to $2/gal. My Duramax was a no brainer when diesel was some 30 cents less/gallon. I wish I held onto my '98. It was a great truck.

[luke]

theses trucks are nice trucks and all but they are supposed to be 4x4s, there to low in the front end and they just dont look tough.interior is not a TRUCK interior and the other one is to tacky.i got nothing to say about the duramax because she is a STRONG motor for work and play, but dodge still takes the cake for the powerplant and eveything else about it.who agrees with me?

[Alan]

Saw one in person today 2500 Chevy extended cab 6.5' box. Looked pretty nice in person it did have driving lights in the bumper to breakup those big corners. Hoping to drive one soon. Shopping for a quadcab 3/4ton 4x4 gas engine. always have been a chevy and ford man. Having a hard time choosing between the two.

[Rick]

I saw the 2500 '08 Duramax in Orlando last week. It looks ok, (I like the GMC) but it is more refined than the Ford F250-450's that were displayed. The dash/interior was amazing in quality. I also saw the Tundra and it's interior is no match but it has a good overhead cam gas motor. The Dodge is a great looking truck but is not up to date like the GM's in refinement. No one else has a 6 spd transmission from Allison The Ford 6.0 had to be replaced (in only a few years) with the 6.4 because of its many problems. My '02 Duramax despite losing an injector (made by Bosch), kept me running some 70 miles through the Kentucky mountains w/almost no oil pressure. That is a reliable motor. The Fords have a "C" channel rear bed frame where the GM's are fully boxed front to rear. I drove the Chevy and with a rack and pinion, it drives/handles deftly like a car. All three have similar good power in their diesels, so that is a matter of choice. All the diesels cost some 7k more for that option. That sucks.

[feet]

I agree, Ihave had two chevy 2500 and now have a ford 250 crew diesel. Nice truck but wnat to get back to gas. Can't even consider a chevy with that ugly bumber and may just kepp my ford for another year. I agree GM and chey put such small rims and tires, it looks silly. I told the salesman it looks like they are designing these trucks for a family car. I use my truck for hunting and off road cabin trips, these trucks look like they sit to low, and how would you know when you can't actually look at one. I agree it is confusing for the consumer having the sierra classic 07 and the new GM 07. I would buy a 07 sierra classic if it had the 3.73 rear but you can only get the 4.10 rear. Looking for better gas mileage. I like how my 250 sits - King Ranch hard to beat.

[tuffguy]

This 2 trucks are nice . but chevy has a very bad habbit of lowering the front 3 more feet that the back and the black plastic that is on the front is always way to low and chevy should make the tire cut out more wider from the side to fit in a big tire incase u don't want to lift it with suspension
