5 Things to Know About the 2018 Chevrolet Colorado ZR2

034A3420 II copy

By Jim Travers

Since its model-year 2015 reintroduction, the mid-size Chevrolet Colorado pickup truck has been a hit: More than 400,000 have been sold and it has raked in more than $10.25 billion in revenue for parent company GM. It's safe to say the market was ready for another alternative to full-size pickups. Chevy upped the ante for 2017 by adding a ZR2 trim level with real off-road cred. The ZR2 spent two years of development time proving its mettle on a purpose-built course in the Arizona desert, on the Rubicon Trail in California, and in various other two-tracks, mud holes, funky spots and varied climates around the U.S. Its development team was made up of real off-road enthusiasts, including the lead engineer.

Here are a few other things you should know about the ZR2.

1. Class-Only Diesel

1 2016-Chevrolet-Colorado-Duramax-TurboDiesel-052 II

Available with a 186-horseppower, 2.8-liter inline four-cylinder diesel engine pumping out 369 pounds-feet of torque, the Colorado is the only mid-size diesel pickup you can buy — at least for now. And all that torque comes in handy on the trail, where the ZR2 crawls easily over rocks and boulders with minimal throttle and drama. It also returns 22 mpg on the highway, according to the EPA.

2. Only E-Locker in Its Class

Another class exclusive is front and rear electronic locking differentials, which can be engaged from the cab. That keeps all four wheels turning at the same speed, something any experienced off-roader will tell you can be a good thing when things get messy.

3. Trick Suspension

Opting for the ZR2 gets you what Chevy calls the first off-road application of its Multimatic Dynamic Suspensions Spool Valve dampers in the mid-size pickup class. What that translates in is progressive-rate shocks with lots of travel; they start softer and stiffen up as they compress. However it works, we can testify that the ZR2 rides remarkably well in the rough stuff.

4. A Step Up

More suspension tweaks include a 3.5-inch-wider track front and rear than a standard Colorado, 31-inch tires and a 2-inch bump in ride height to help you clear obstacles on the trail. It also has skid plates for when you don't.

5. Exhaust Brake

Chevrolet and GMC are the only small-diesel makers that include a dedicated diesel exhaust brake switch to allow for added exhaust back pressure to better control heavier loads or trailers. The Ram 1500 doesn't offer it on the EcoDiesel and the new Ford F-150 Power Stroke doesn't have it either.

ZR2, the ultimate off road weapon.

I think it's great that GM copies other, in fact, Ford gave up their 32V OHC Technology to GM so they can build their first OHC mid engine car.

I think it's great Ford surrenders their engine designs so GM can better themselves.

In fact, we also heard how they're using turbo technology, I think it's great, it's like that one kid in school that always copies your homework, get's an "A" grade, but his work looks like crap.

6) It's too small for what you have to pay. Ballers who can afford one will buy a full-size Raptor.

@ Frank: (1) Google Cadillac 4.6 north start engine.
(2) next, punch in Fiero.

Now read some or have someone read for you.

North Star engine

Power Wagon don't care! Power Wagon don't care about ZR2!

Ford wishes they could build a off road truck this good. Don't worry though, ford will try and copy it.

bad tranny

LMFAO

Look at the excuses Frank and Chris have.

The ZR2 is the best off roader built in 2018!! That's a fact! Its perfect in size and capability!!

Ford can't get the Ranger Raptor out fast enough... Thats why they are rushing it into production.

1. GM did not built it, it was a French Company. GM scrapped it because it was junk in Cadillacs.

2. The mid-engine Fiero 2.5L Iron Duke engine was GM's biggest failure, and it was OHV.

Why are you worried of Ford and the Ranger, are you scared people would want the Ranger Raptor? Then your comment is 100% accurate.

Just rolled off the lot in my brand new raptor. Can't believe I've been such a gm lover all my life. There stuff is such junk. The Fiat stuff isn't any better.

Where are these precious GM engines of yours today? In what car?

Heck, Ford is going on 30 years building 32V OHC V8s

Heck, GM copies Ford. That's why Ford had to team up with GM to get a 10-speed tranny. They'd still be rolling their 6-speed. It's ok though cuz Ford sells more lol..@ Frank

@ Frank

I'm not worried. Its ford that is worried, heck, their so called mighty raptor gets its @$$ handed to it for past 3 years in all reviews with ZR2.
Common sense my man!!! Maybe they will make the baby rsptoe without plastic 4 wheel drive parts??? Lol.

@Frank

You need to stick to what you know. GM was building multi-valve engines long before they became available in Fords. GM was using aluminum decades before Ford. Ford was a joke until the 1980s.

Get the story straight, you nutca$e


Ford and GM partnered to build a 9 and 10 speed tranny.

Ford the 10, GM the 9.

GM offered Ford the 9, Ford,..............helldafuqnah!!!fuckouttahereGM

Hahaha! Franky is all upset because I proved it wrong yet again.

And which 32V V8 is used the GM Cars/Truck now that has been built since the 90s?

ZERO!!!

Ford had Aluminium 32V V8 since the 40s.

You really do not know your past with your age and all.

Hahaha! Franky is all upset because I proved it wrong yet again.


Posted by: GMSRGREAT | Jun 1, 2018 3:18:58 PM

You always prove me wrong, I thought you were educated.

@TNT

The Raptor is in a class of its own. The ZR2 would get it's @ss handed to by the Jeep Rubicon.

Your post are as stoopid as you.

Heck, I guess partnered and teamed up is different. Ford sells more though

As papajim said, stick to what you know. Heck, I guess that means Ford sells more lol

Clearly, they have a better product. In fact, that's how business and economy is ran, build a good product, and it will sell.

Dude, it's that simple b!tch@$$

@Frank

You are seriously embarrassing yourself. Ford's V8 in the 1940s was a cast iron block/heads 2v engine called the Flathead. GM actually built

As with every story on this website no matter the topic, all Franky boy has is his sales numbers!! Heck, your fun to pick on lol

Ford builds junk, any questions?
The Raptor is in a class of its own, a very low class.

Your business would go bankrupt just like GM, please DO NOT EVER TRY TO RUN ANY KIND OF BUSINESS IN AMERICA.

Heck that's what Frank has to do before every comment, Google.

@ Frank

Here we go again!! Good gosh, u get put in your place and u can't control yourself.

There's a smart comment. If you had a clue...at least Ford sells more

@Frank

How many Sherman tanks have you driven?

@ TNT

Exactly, out of control! But it's pretty funny!

Point is they've been building the OHV V8 since then, you KOO KOOs.

Peace out, I have a life to live.

Grossly overpriced but I certainly wouldn't choose a Raptor over it; the Raptor's even worse.

Of course, the only people likely to buy a Raptor or a ZR are going to be the ones needing a status symbol, not a real, useful, utility truck.

Poor guy got ran off, he had to go check today's sales numbers lol

I really like my ZR2, it hauls all my hunting gear, pulls the boat just fine, even hauled a Bull Elk(at least the meat and antlers) and a 165inch whitetail.
It cruises through cow pastures and crawls thru the rocky mountain trails. Plus glides down the highway. The dual e-lockers are da bomb, have had to use them a couple times in the muck...the heated seats work great, remote start while walking from the tree stand and the seat is already hot for you.
Does it cost more then a regular Collie/Canyon, yep but it comes standard with a lot of things that are optional or ya just cannot get on the regular ones.

Where did Chris and Frank go?

that v8 GAA started life as a v12, hence 60 deg angle. it was of similar design of a Allison Engine (GM at time) and the rolls merlin ford got blueprints to build. Still rather push rods and 16v in my v8s.

Ford may sell the most trucks. But at least GM has the loudest most ignorant fanbois.

hEY i AM THE LEADER OF THE gm IGNORANT PAK.

Yes Ford is #1 in sales and my boyfriend and I are the leaders of the sissy Ford girls!

Consumer Reports , July 2018 issue

The 2018 F-150 made the:

And the first 20 years of them were complete and utter trash. The 4.6 SOHC was embarrassingly gutless. The 32V 4.6 was famous for worn out valve guides and burnt valve seats. The 5.4 SOHC was gutless too. The 5.4 Triton was weak and impressive only in just hot unreliable it was. The 32V 5.4 needed a blower to make good power and inherited most of the problems its predecessors had. And from what the ecoboost guys have pointed out, the 5.0 Coyote had plenty of problems in the first few years (and there are still plenty of issues Ford has left unfixed). Even the latest and greatest, the 5.2 Voodoo, is an epic oil burner (burns more oil than a diesel according to Car and Driver lol. 2 quarts every 1,000 miles is normal? Whatever you say Ford).

Frank isn’t telling the whole truth here.
The GAA was a Sherman tank engine that weighed almost 1,600 lbs, was 1100 cubic inches and only made 500 hp.
It was a Ford version of the RR-Merlin design that Ford lost a bid to build.
Deere and Company made Hyd cylinders for Grumman helcata, but that’s doesn’t mean they pioneered advanced avionics.
Ford 4.6/5.4/V10 “modular” SOHC/DOHC motors are another Ford design...C grade. Ford has been notorious to early adopt a concept, run full tilt, then scrap it. The mod motor was designed on a narrow bore centerline to for their FWD platforms, which limited displacement. Ford’s solution was a tall deck height, under square bore to stroke ratio, and crazy high port velocities that require high-flow heads, but are hampered by high rpm harmonics. Toyota’s 5.7 uses the same philosophy, but has better management controls to make it acceptable.
But we can go further back with Ford. The Ford flathead was a turd. Stock Buick straight 8s destroyed the Flathead, in heavier cars, with shiftless 2-speed Dynaflow.

The ZR2 has an electric locker because the Gov-Loc GM loves so much is failure prone on pavement, let alone off road.

The ZR2 is a good effort, but one had to wonder was a Jeep Pickup with Rubicon package will do to the ZR2?
Spool valve shocks and high-speed desert running is all well and good, but much like the Raptor, it is filled with compromises.

Would I buy one? No.
Not enough torque and weak IFS related steering components.
I know, I know, off road racing. Funny how these IFS and IRS trucks can race in AZ, Nevada, even Mexico, but jack up a tie rod on some of the busiest trails in the Rockies.
Just because GM tests something somewhere, doesn’t mean the truck successfully made it.

you guys make it too complicated
allow me to make it simple to understand;

#1 an engine is more of a giant air pump meaning the bigger, higher displacement the larger and more cylinders V8 means the more air it pumps in resulting into more power.

#2 a 5.7 V8 pulls in 37,000 liters of air every minute

#3 a F-150 with the 3.5 Eco-Boost V6 WITH the twin turbo pulls in 54,000 liters of air every minute

moral of the story
yes, the V6 with smaller and 2 less cylinders can pull in MORE air resulting in MORE power making it more efficient

the V8 is dead and in your peabrain mind you only think it's more powerful cause of the stronger sound of the engine

"#1 an engine is more of a giant air pump meaning the bigger, higher displacement the larger and more cylinders V8 means the more air it pumps in resulting into more power.

#2 a 5.7 V8 pulls in 37,000 liters of air every minute

#3 a F-150 with the 3.5 Eco-Boost V6 WITH the twin turbo pulls in 54,000 liters of air every minute"

That's nice. Unless Ford figured out a way to run a gasoline engine at 16:1 AFR under load, your statement only tells us the ecoboost is capable of burn FAR more fuel every minute than a big V8.

Volumetric efficiency DOES NOT HAVE ANYTHING to do with fuel efficiency of an engine.
--------------------------------
"moral of the story
yes, the V6 with smaller and 2 less cylinders can pull in MORE air resulting in MORE power making it more efficient"

What does any of that have to do with fuel efficiency? Brake specific fuel consumption is one of the main ways you calculate fuel efficiency. Have the BSFC of a 3.5 EB?

If I remember correctly, the 5.3 and 6.2 V8's delivered better fuel economy than the 3.5 Ecoboost in the Texas Truck Showdown even though both V8 trucks weighed at least 500 pounds heavier.

"the V8 is dead and in your peabrain mind you only think it's more powerful cause of the stronger sound of the engine"

Sorry but youre the peabrain here.
