The Chevy Colorado Diesel is just starting to arrive at dealerships. I recently had a chance to take a fully loaded Colorado Z71 Trail Boss with the all new 2.8L Duramax Diesel off-roading in the dusty Nevada desert. How does the special edition Colorado perform off-road? Does the Duramax help or hurt the midsizer? Should you upgrade your Colorado with GM's available performance parts? Let’s go and find out!

Thankfully, being the first few days of November, I didn’t have to worry about the scorching heat of the Nevada desert. I was, however, warned not to wander off the road too far off the road and be on the lookout for rattlesnake. While I never did see any menacing wildlife, the prospect we might made our time with the Trail Boss all the more exciting.

 

I’ve long been a fan of diesel engines for small pickups and SUVs. The low end torque focused nature of the diesel matches nicely with the low-speed driving most owners of these types of vehicles do most. Or at least, at least the type of driving they want to do most. So, to see the Colorado’s off-road model paired with the brand’s new small Duramax Diesel engine is satisfying.

When we gave you our first on-road impressions of the 2.8L Duramax Diesel for the mid-size trucks it was on paved roads and smoother all-season tires. The Trail Boss takes the Colorado to an off-road slant, with large knobby tires, slick LED lights, a blacked out bowtie, and a tubular steel sail at the front of the bed. That’s just naming a few of the features.

 

Traveling down what some might call a "road" in the middle of the Nevada desert, the Trail Boss Diesel I’m piloting reminds me a whole lot of the S-10 ZR2 I used to own nearly a decade ago. A fat low end torque curve and capable off-road parts leave me feeling confident as we traversed through narrow canyons and washed out dry river beds.

 

Without a doubt, the 2.8L Duramax shines in this type of work. The key to off-road driving is slow deliberate movements. With 369 lb-ft of torque on tap at low RPM, piloting off-road at a measured crawl is a pleasure. The Trail Boss’s Wrangler Duratrac tires grip loose dirt and rock substantially better than the standard all-season radial tires that come on a Z71 model. The tubular side steps provide substantial rocker panel protection.

 

Better yet, even if you already own a Colorado, you don’t have to buy a brand new Trail Boss to experience these upgrades. Just pick up a 2016 GM Performance Parts Catalog and turn to page 66. With a little time and money, you can turn your own truck into a Trail Boss, right in your own garage. The company offers off-road Wrangler Duratrac tires, black aluminum wheels, floor liners, color matched grilles, and even a transfer case shield. For performance oriented owners, a performance exhaust and air intake are also available. Best of all, every single one of these parts is covered within your vehicle's factory warranty.

To add some depth and compare, I also drove a Performance Parts loaded Silverado High Country. While the Silverado exhibited a more plush ride, it’s wider girth made it substantially more difficult to maneuver on the tighter sections of the trail. Capable in its own right, the Silverado didn’t give me the same confidence that the narrower Colorado did. This is one circumstance where the just-a-little-bit-smaller outside proportions of the mid-size make all the difference.

If you're looking for a utilitarian vehicle that can take you far off the beaten path, the Colorado Trail Boss should be right up your alley. Chevrolet has a unique offering with it's 2.8L Duramax that you can't find anywhere else. That sets the Colorado to become a popular off-road platform, ripe for modification.

 

You can head down to your Chevrolet dealer and purchase your own Trail Boss straight from the factory, or if you already own a Colorado outfit it with the same parts from GM’s Performance Catalog. You can read the all new edition right here.

We have a ext.cab Colorado that just came in (3.6) off the delivery truck that is a Trail Boss. Stickered for a little over $42k. The Trail Boss package is $7k and change alone. They look awesome but...a tad steep IMO. They still need to do a ZR2 as the Trail Boss...well...as cool as they look, they aren't a ZR2...

Can't wait to get mine. It's a diesel Trail Boss standard bed in blue. Dealer has issued my order, but don't have an allocation for it yet. They are still only allocating a handful of diesels each week and availability of the gas seems real thin also. My dealer was supposed to get 6 allocations yesterday, but they reduced it to 3.

Ok - I'm sure I won't be the only one to ask - but any real 4x4 required travels? Everything in the pictures looks like a FWD Impala could roll down that gravel road. I know the publicist from GM was likely leading the group - but did anything require any concern for ground clearance, approach angle, anything? Or anything where even a 2wd locking differential would have to engage?

I agree with 08 SBirch. This Duramax Colorado is a sweet truck...everything but the front end. It doesn't matter how many grill-black outs I can purchase, or even a good set of Wrangler Duratracs, that front bumper will kill all of your off-road performance. It's the reason my Sierra HD is relegated to nothing more than trailering duty, the approach angle virtually guarantees you will crack your bumper, even if you remove the air-dam ahead of time.

Why doesn't chevy offer a REAL off-road package?
The 2015 TRD Pro Tacoma is stock with a 37.8 degree approach angle. That's your competition. The Colorado Z71 approach is 17.3 degrees.....that's why this dirt road looks like something an Impala can drive over...because it can.

I want to see the Trail Boss on Poison Spider in Moab, out of the box. The TRD Tacoma can do it.

A mini chevy duramax drivetrain would be a dream for many over landers and off-road enthusiasts alike; however, the amount of "mod" $$ to fix that approach angle makes the Tacoma king of the hill again.

I understand why they have the low bumper: Improved MPG to meet the EPA's standards. That's fine. Offer the base with it. Customers who order the "Trail Boss" would take 30 degree approach at the expense of 2-3mpg every day of the week.

It's sad that the last out-of-the-box off-road able Chevy was the H2/H3 combo. This is exactly why Jeep is selling everything their factory can produce, and with a wrangler-based truck coming in '16 with the Dodge Eco-Diesel and this Colorado "Trail Boss" is DOA.......despite having the better engine/tranny combo.

Agree with the off-road lite comments. That was a dirt road and not off-road".

 

I miss the days of metal bumpers and 24" of clearance under the radiator. There is so much plastic so low to the ground on my 2008 4x4 Sierra that the truck is essentially a plow off road.

 

I am optimistic that the little oil burner will be a game changer in the mid-size pickup truck market. I love the L76 monster 6L engine in my crew cab, even though it only gets 10 MPH, but since I have crested 60 years old, I'm looking to downsize and slow down a bit. The Colorado Duramax might be the ticket.

 

If I bought one the first thing that I'd do is yank off that front end plastic and replace it with one of the after market steel bumpers like FabFours or Boondock.

Poison spider is not rough enough; give me one to hit Moab Rim, Steelbender, Metal Masher. Lets see how many rear end parts are ripped off on the wall, and front end parts on the fall. :ughdance: And never saw a stock TRD do Steelbender or Metal Masher the entire time I spent in Moab, which was six years, and with a Rubicon and Hummer, i ran every trail they had except for Coyote and Pritchett.

Aww man, ouch The photos I took happened to be on the best parts of the trail with the most room for us to get out and stretch our legs. Yes, there was a group of us led by an instructor. We did actually use 4WD high during most of the drive. :dunno:

 

Not sure what I can say other than acknowledging it's not the Rubicon Trail and it could have been worse but that I got a sense the Colorado Diesel is going to be a trail monster versus the Silverado on what I had available to me.

 

Hopefully we'll get a chance to drive one for longer than a few hours in the near future. :thumbs:

Vs. the Silverado? Yea, can't be any worse. :thumbs:

GM is probably banking on the fact that the wannabe off-roaders will buy this...it is a nice looking truck. If I spent $42k on a truck, it wouldn't leave the pavement...not on a "real" trail anyways. I'm no off-road enthusiast, but my mindset is: if I own a truck I would like it to look like it's at least capable of going off road. I got a 2" level and some mild AT tires...that's good enough for me. You guys with 6+ inches of lift are nuts...I would hate getting in and out of a truck that tall every day.

    • Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package. 
    • So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.  
    • Have considered installing a DC to DC charger in your camper to replace your isolator?  
    • Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.  
    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.
