what the hell is this thing? i saw what looked like a hybrid between an s10 and a new silverado, and my buddy said it had Colorado on the side. is it really an in-between truck or closer to full size? weird.

 

[Guest]

It's Chevy's new mid-size truck. I just wish they would have put the engine from the Trailblazer in it. 270 HP in a mid-size, that would have been cool.

 

[889]

Yah, i second the engine opinion, they're running a 4cyl and 5cyl version of the inline 6, why not just offer the 6, and maybe the 5.3 v8 like the long trailblazer. Chevy built a truck more the size of a dakota, but without the same power options......

 

[875]

the inline 5 has more horsepower then the Vortec 4300 V6 currently available

 

[889]

True, but its an all new truck, why not use the newest 6 cyl instead of settling for a 5cyl? You can't have too much power......

Plus, the dodge dakota is avaiable with the 5.9 in the RT.

 

[875]

To hell with the 5.9 Chevy should throw a 6.0 in the Colorado, or bring back the old 454 SS trucks from the early ninties and put them on the Colorado Base

 

[889]

Yah, they should, im just using the 5.9 for comparison because the dakota seems to be the colorado's direct competition.

 

[CodyZ71]

I saw one the other night. And I think both this and the fullsize Silverados SHOULD HAVE A 5.7! In the far future, when my truck is dead... And I buy a truck, it will be a duramax... unless they started putting 5.7's in again....

 

[2573]

oh that hurt my eyes...why settle for Duramax when you could get a PowerStroke?

Ill give it to Chevy though, that Allison tranny is pretty nice. heres the rankings
1. PowerStroke
2. Cummins
3. Duramax
Not my opinion, tests have proven it, and they have also proevn that the same order goes for the 3/4 ton trucks' offroad ability.

 

[875]

are you talkin about the new HO Cummins, 24V or 12V
personally Id take a 12v Cummins over any deisel on the market

 

[muddybronco]

so are they gonna replace the S10 or is this supposed to be in between it and the full size trucks? the standard 4-cyl was pretty dissapointing, when I saw the truck I figured a V6 would be the bare minimum, with a V8 a more reasonable option. oh well

 

[889]

They are stopping the S10 except for the 4 door crew cab version.

 

[CodyZ71]

Bah disappointing! The 4.3 is a good engine! And S10's make coool street trucks, I don't see a Colarado looking very streetish... Chevy is getting suckier everyday.
Oh and don't get me wrong, I like powerstrokes and cummins.

Funny you should mention the diesels. From a press release:

In reply to:

Duramax 6600 Provides Major Improvements In Power, Torque, and Emissions

PONTIAC, MICH. - GM's Duramax 6600 6.6L turbo-diesel V-8 engine will provide higher power and torque ratings and major emission improvements beginning in January 2004.

Silverado and Sierra 2500HD and 3500 Series trucks with the Duramax 6600 and the Allison automatic transmission will receive a new version of the engine with 310 hp @ 3100 rpm, 10 more horsepower than before. The engine also features a higher torque rating of 590 lb-ft @ 1600 rpm, a 70 lb-ft increase over its previous maximum high. At the same time, Duramax 6600 NOx emissions have been reduced almost by half.

"Since its introduction in 2001, the Duramax 6600 has re-established GM in the full-size diesel powered truck market by increasing our share of the segment to nearly 30 percent," said Charlie Freese, executive director, diesel engineering for GM Powertrain.

Silverado and Sierra models with the Duramax 6600 and a standard ZF S6-650 six-speed manual transmission receive the same emissions improvements as those with the Allison 1000, with carryover power ratings.

Whoa I figured maybe in a year or two they would catch up with dodge and ford... But just like that! Gotta love the duramax

I remember back in 2000 or so they said when the competetion catches up all they have to do is reprogram it?

 

[tanbuddy]

Did they put a variable geometry turbocharger on it like the powerstroke 6.0 has? I herd that is the trick they used for the pwer gains

oh my gosh, that kicks my torque right in the balls. how much is the engine sticker price?

 

[c_rock]

I haven't seen the Colorado yet, but did see an SSR at a dealer in Texas last week. That thing is wild.

Well... more from the press release:

In reply to:

Both the new version of the Duramax 6600 turbo diesel with the Allison automatic transmission and the version with the standard ZF six-speed manual feature improved hardware. The new version also has additional software calibration changes to help provide its higher power output.

Primary hardware changes include a variable nozzle turbocharger, new electronic control module, next-generation fuel injectors, electronically controlled cooled exhaust gas recirculation (EGR), 50 state catalytic converter usage, improved charge air-cooling and a closed crankcase ventilation system:

The common rail fuel system also uses smaller, more precisely machined and positioned next-generation fuel injectors to inject its fuel pulses into the cylinders. The injectors are now fully accessible, allowing service technicians to access them without having to take the cylinder head cover off. Servicing is typically required only every 100,000 miles or more.

The new variable nozzle turbocharger features vanes that are now hydraulically controlled to precisely adjust the level of boost generated by the turbocharger.

A more powerful, 32-bit, next-generation engine control module provides the capabilities for integrated control of the additional engine hardware. The new engine controller provides faster microprocessor speeds, increased throughput and more memory than the previous generation controller.

The EGR system in conjunction with catalytic converter usage reduces NOx emissions in all 50 states to approximately 2 grams per brake horsepower hour from a previous 4 grams in 49 states and 3.5 grams in California.

Charge-air cooling is used to provide cool dense air to the cylinders to help generate the new engine's increased power, torque and improved emissions.

The closed-crankcase ventilation system, although not required to meet 2004 emissions regulations, anticipates upcoming 2006-model emissions requirements by incorporating a closed crankcase ventilation system in which harmful vapors are vented internally and burned as part of the combustion process, rather than being vented to the outside atmosphere.

"The engine's high torque across the power band helps Duramax 6600-equipped GM trucks excel in off-the-line performance, acceleration and heavy-duty trailering and hauling," Freese said.
