Why This Comparison Matters
When MotorVero first published our head-to-head feature comparing the 2017 Chevrolet Colorado ZR2 and 2017 Toyota Tacoma TRD Pro, reader response made it clear we needed to dive deeper into our testing methodology and results. This isn't just another truck comparison - it's a battle between two fundamentally different approaches to mid-size off-road dominance.

Key Differences at a Glance
- Engine Options: ZR2's available turbo-diesel vs TRD Pro's V6 gas
- Suspension: Multimatic DSSV dampers vs Toyota's TRD-tuned springs
- Approach Angles: 30° (ZR2) vs 35° (TRD Pro)
- Price Point: ZR2 typically $3,000-$4,000 higher
Testing Philosophy: Real-World Performance Over Spec Sheets
We deliberately avoided a strict apples-to-apples comparison (V6 gas engines only) because the Colorado ZR2's available 2.8L Duramax turbo-diesel represented a game-changing option in the mid-size off-road segment. As the first production-ready diesel ZR2 available from GM, this configuration offered unique insights into alternative off-road powertrain solutions.
For readers specifically interested in gas-engine comparisons, we conducted separate testing in our 2016 Midsize Pickup Truck Challenge that pitted the V6 versions against each other.

Comprehensive Testing Methodology
Our evaluation process spanned multiple terrains and performance dimensions:
Initial Measurements & Technical Assessment
- Precise ground clearance measurements at multiple points
- Bed height comparisons with various payload scenarios
- Tire size analysis and pressure optimization tests
- Suspension articulation measurements using RTI ramp
Hungry Valley Off-Road Testing
Located just north of Los Angeles, Hungry Valley State Vehicular Recreation Area provided the perfect controlled environment for our initial comparison with:
- 200+ miles of diverse trails and obstacle courses
- Back-to-back testing of off-road modes and traction systems
- Controlled hill climbs with varying surface compositions
- Detailed evaluation of crawl control vs traditional 4WD systems
Key Findings From Technical Testing
The ZR2's Multimatic dampers demonstrated superior high-speed compression control, while the TRD Pro's suspension geometry allowed better low-speed articulation. The diesel torque advantage became immediately apparent on sustained climbs, though the Tacoma's lighter weight helped in quick direction changes.

High-Speed Off-Road Performance
Moving to more remote sections of Hungry Valley, we evaluated how each truck handled high-speed desert running:
| Performance Metric | Colorado ZR2 | Tacoma TRD Pro |
|---|---|---|
| Whoop Section Stability | More controlled but stiffer ride | Softer but required more correction |
| Rutted Trail Comfort | Superior wheel independence | More chassis flex noticeable |
| High-Speed Cornering | Predictable understeer | Lighter feel but less planted |
This phase revealed how each manufacturer prioritized different aspects of off-road performance, with the ZR2 favoring precision and the TRD Pro emphasizing traditional body-on-frame flexibility.
Extreme Environment Testing: Dumont Dunes
Our final testing grounds at Dumont Dunes Off-Highway Vehicle Area presented unique challenges:
Sand Performance Evaluation
- 1/8-mile drag comparisons in varying sand conditions
- Hill climbs on 30°+ sand faces
- Low-range crawling through dune valleys
- Traction system effectiveness when partially buried
The fine, powdery sand at Dumont proved particularly challenging, with both trucks requiring multiple recovery attempts. This environment highlighted how:
- The ZR2's torque advantage helped maintain momentum
- The Tacoma's lower weight reduced sinkage in soft areas
- Each truck's electronic aids responded differently to loss of traction

Final Assessment: Strengths and Weaknesses
Chevrolet Colorado ZR2 Advantages
- Powertrain Flexibility: The available diesel offers unmatched low-end torque
- High-Speed Control: Exceptional damping on rough terrain
- Technical Terrain: Precise rock crawling capabilities
Toyota Tacoma TRD Pro Advantages
- Approach/Departure Angles: Better clearance on extreme obstacles
- Weight Distribution: More nimble feel in tight situations
- Aftermarket Support: Stronger parts ecosystem
MotorVero's Final Verdict
After subjecting both trucks to half a dozen distinct terrain types and challenging scenarios, we found their performance differences primarily manifest at the extremes. The Colorado ZR2 represents an impressive return to serious off-road capability for Chevrolet, particularly with its available diesel option. Meanwhile, the Tacoma TRD Pro continues to deliver the proven, balanced performance that has made it a segment favorite.
For buyers prioritizing technical rock crawling or high-speed desert running, the ZR2's sophisticated suspension and torque-rich diesel give it the edge. Those valuing traditional off-road feel, aftermarket options, and slightly better extreme angles may prefer the TRD Pro. Both represent excellent choices that outperform 90% of buyers' actual needs.
Frequently Asked Questions
Which truck has better fuel economy?
The diesel-powered ZR2 achieves significantly better highway mileage (22-26 mpg vs the Tacoma's 18-20 mpg), though city figures are closer. Real-world testing showed the diesel's advantage grows during low-speed off-road use.
How do the interiors compare for long-distance comfort?
The Colorado offers more contemporary interior materials and tech features, while the Tacoma provides more traditional truck ergonomics. Seat comfort proved subjective, with some testers preferring each truck.
Which holds its value better?
Toyota traditionally has stronger resale value, though the ZR2's unique positioning may help its long-term value retention compared to standard Colorados.
