This page carries the numbers: engine output, exterior and interior dimensions, capacity by configuration, wheels and tires, EPA mileage, the feature grid and the warranty terms. Where two published records disagree, that is said here rather than papered over. For what the trims cost and what each step adds, see Colorado trims and pricing; for the full lineup picture, the Colorado overview.

Engine Specifications

One engine, six trims, no options. That is the whole powertrain section.

2.7L TurboMax turbocharged four-cylinder

Displacement	2.7 litres, inline four-cylinder, turbocharged
Horsepower	310 hp at 5,600 rpm
Torque	430 lb-ft at 3,000 rpm
Transmission	8-speed automatic, the only gearbox offered
Fuel	Regular unleaded
Fuel tank	21.4 gallons
Drivetrain	Rear-wheel drive standard on WT, Custom and LT with four-wheel drive available; four-wheel drive standard on Trail Boss, Z71 and ZR2
Axle ratio	3.42

There is no V6, no diesel and no hybrid in this generation. Chevrolet describes the 430 lb-ft figure as best-in-class standard torque for the segment.

Exterior Dimensions

Overall length	212.7 to 213.2 inches across the lineup
Wheelbase	131.4 inches
Width, mirrors folded	74.9 inches on WT, Custom and LT; 76.3 on Z71; 78.1 on Trail Boss and ZR2
Width, mirrors out	84.4 inches, every trim
Overall height	78.8 to 81.9 inches, tallest on the ZR2
Ground clearance	9.5 inches on the Trail Boss; 10.7 inches on the ZR2
Curb weight	4,310 pounds, rear-wheel drive
Gross vehicle weight rating	6,050 pounds, rear-wheel drive
Body	One configuration only: crew cab, 5-foot bed

Two figures we do not print per trim, and why. Curb weight and gross vehicle weight rating are published differently by different records. On the four-wheel-drive and off-road trims the two most authoritative sets differ by roughly a hundred pounds on every configuration. Rather than pick a winner, the rear-wheel-drive figures above are the ones both agree on, and the number that governs your truck is printed on the tire-and-loading label inside the driver's door. Ground clearance below the Trail Boss sits in only one record, so it is not printed here either.

Interior Dimensions

Measurement	Front	Rear
Head room	40.3 in	38.3 in
Leg room	45.2 in	34.7 in
Shoulder room	57.4 in	56.1 in
Seating	5 seats, every trim
Upholstery	Jet Black cloth and Jet Black leatherette, by trim

Capacity and Capability

Configuration	Max trailer weight	GCWR
2.7L TurboMax, rear-wheel drive, crew cab	7,700 lbs	13,250 lbs
2.7L TurboMax, four-wheel drive, crew cab	7,700 lbs	13,250 lbs
2.7L TurboMax, ZR2, four-wheel drive	6,000 lbs	11,600 lbs

Both of those ratings carry equipment conditions, and Chevrolet publishes no gooseneck or fifth-wheel figure. Payload spans roughly 1,445 to 2,046 pounds across the crew cab configurations above, with 1,710 pounds on a rear-wheel-drive build. The conditions, the per-configuration payload figures and what any of it means with a trailer attached are worked through in full one page over.

The bed measures 5 feet, 61.7 inches on the floor, and holds 41.9 cubic feet. It carries a mid-position tailgate rated to 500 lbs, a built-in measurement tool and cargo bed lighting. Full trailer detail sits on the Colorado towing capacity page.

Wheels, Tires, and Brakes

Trim	Wheels	Tires
WT	17 x 8	255/65R17 all-season
Custom	18-inch high-gloss black aluminium	All-season
LT	17 x 8 argent finish	255/65R17 all-season
Trail Boss	18 x 8.5, 20-inch available	265/65R18, 32-inch all-terrain
Z71	18 x 8.5, 20-inch available	265/65R18, 32-inch all-terrain
ZR2	17 x 8	LT285/70R17, 33-inch mud-terrain

Freeze and thaw cycle through this region all late winter, and the potholes that opens up cost more wheels, tires and alignments than the mileage ever does, which is a real argument for the 17-inch wheels and their taller sidewall over the 20-inch options.

Fuel Economy and Range

Configuration	City	Highway	Combined
Rear-wheel drive	19 MPG	24 MPG	21 MPG
Four-wheel drive	17 MPG	22 MPG	19 MPG
Four-wheel drive, mud-terrain tires	17 MPG	20 MPG	18 MPG
ZR2	17 MPG	17 MPG	17 MPG
ZR2 Bison	16 MPG	16 MPG	16 MPG

EPA estimates, published at fueleconomy.gov. On a 21.4-gallon tank, the rear-wheel-drive combined figure works out to roughly 449 miles between fills. Your mileage will vary.

Key Features by Trim

S = standard · O = available · not std = not standard equipment on that trim, which is not the same as unavailable. A feature whose scope could not be confirmed on every trim is left off this grid rather than part-filled. The deeper per-trim breakdown lives on Colorado trims and pricing.

Safety and Compliance

Nothing in the driver-assistance column changes as you climb the trim ladder, which is unusual and worth knowing before anyone tries to sell you up for it. Six items travel under the Chevy Safety Assist name on all six trims. Two more that buyers usually expect to pay for do not: blind-spot monitoring, and front and rear cross-traffic alert. NHTSA's own record for this truck separately lists electronic stability control, forward collision warning and lane departure warning as standard.

The six under the Chevy Safety Assist name are automatic emergency braking, front pedestrian braking, forward collision alert, lane keep assist with lane departure warning, a following-distance indicator, and IntelliBeam high beams.

Rating body and test	2026 Colorado result
NHTSA overall	4 stars
NHTSA frontal crash	4 stars
NHTSA side crash	5 stars
NHTSA rollover	3 stars
IIHS small overlap front	Good
IIHS moderate overlap front	Marginal
IIHS side	Good
IIHS front crash prevention, pedestrian	Acceptable
IIHS front crash prevention, vehicle-to-vehicle	Poor

Both rating sets are published in full at nhtsa.gov and iihs.org, where they are also dated. The Colorado does not currently hold an IIHS award.

Warranty Coverage

Bumper-to-bumper	3 years / 36,000 miles
Powertrain	5 years / 60,000 miles
Rust-through	6 years / 100,000 miles
Corrosion	3 years / 36,000 miles
Roadside assistance and courtesy transportation	5 years / 60,000 miles

Original tires are covered under the bumper-to-bumper term, prorated after 12,000 miles, and Connected Access runs 10 years. Corrosion coverage and rust-through coverage are separate terms and are often quoted as one; they are not. Intervals, the covered first visit and what ownership actually costs here are on the Colorado maintenance page.

What These 2026 Colorado Numbers Mean in Practice

The number	What it decides
78.8 to 81.9 inches tall	A standard residential garage door opening is about seven feet. Every Colorado clears it, but a ZR2 with a roof rack or a light bar does not have much left. Measure before you buy the accessory, not after.
84.4 inches wide with mirrors	A single garage bay is typically eight feet of clear opening. That leaves roughly half a foot a side with the mirrors out, which is why they fold.
212.7 to 213.2 inches long	A standard parking space is eighteen feet. The Colorado fits inside one; a full-size crew cab does not.
34.7 inches of rear leg room	Two adults behind two adults is comfortable. Three across the back seat works for a school run and gets tight beyond an hour.
5-foot bed with a mid-position tailgate	The mid-gate stop is what lets 8-foot material ride supported rather than balanced on the tailgate edge. It is the single most useful thing about a short bed.
6,050-pound GVWR against a 4,310-pound curb weight	That gap is what you get to fill with people, gear, a hitch and tongue weight, and tongue weight is part of it, which is the calculation most first-time towers skip.

Two of those numbers do more work in the Lehigh Valley than anywhere else. The 84.4-inch mirror width is the figure that decides whether a truck is pleasant on MacArthur Road in Whitehall, where the big-box lots were striped long before crew cabs were the default. And the 213-inch overall length is why a Colorado parks in Bethlehem's Historic District and in downtown Easton, on streets laid out for horses, while the full-size alternative circles the block. Buyers drive to us from Bethlehem, Easton, Emmaus, Nazareth, Whitehall and Slatington, and the tape measure is usually what settles it. A Nazareth garage built in the eighties and a Slatington one built last year ask very different questions of a 213-inch truck, and Emmaus row-house driveways ask a third.
