If GMC really is bringing back the Jimmy as a body-on-frame SUV, it opens the door to a bigger question.
What if Cadillac followed the same playbook?
We already know GM has a highly capable midsize truck platform in the Chevy Colorado and GMC Canyon. We also know the industry is shifting back toward rugged, body-on-frame SUVs in a big way. This month has seen Hyundai and Kia jump into the body-on-frame chat, as well as leaks suggesting that GMC would make a Jimmy once more, and confirmation from Nissan that a body-on-frame Xterra is returning by late 2028.
So what happens if Cadillac takes that formula and builds a true luxury off-road SUV to take on the likes of the Lexus GX 550 Overtrail?
It Starts With the Same Playbook: Truck Bones Matter
If Cadillac were serious about competing with the GX 550 Overtrail, this couldn’t be another crossover.
It would need to follow the same formula we’re seeing across the industry, take a proven midsize truck platform and turn it into something more refined, more premium, and more capable.
That means body-on-frame construction based on the Colorado and Canyon. That platform already delivers excellent off-road capability in ZR2 and AT4X trims, with great articulation, solid approach angles, and the kind of durability buyers in this segment expect.
Cadillac wouldn’t need to reinvent the wheel. It would just need to elevate it.
Powertrain Is Where Cadillac Could Flip the Script
To take on the GX, it would also have to use internal combustion.
The GX 550 Overtrail runs a 3.4L twin-turbo V6 making 349 horsepower and 479 lb-ft of torque. It’s strong, smooth, and paired to a 10-speed automatic.
Cadillac has options.
The obvious starting point is GM’s 2.7L turbocharged four-cylinder, already making around 310 horsepower and 430 lb-ft in truck applications. It’s torquey and proven.
But let’s be honest, that’s not enough to make this thing feel like a Cadillac.
Cadillac should go bold with a small-block V8. A V8-powered midsize luxury off-roader would instantly stand out in a segment full of turbo sixes and turbo fours.
That alone could steal buyers from Lexus.
It Would Be a True GX 550 Overtrail Rival, Not Just a Soft Luxury SUV
The GX has a long pedigree of off-road heritage. It has a cult-like following that would not just flock over to Cadillac for a mere imitation.
With features like front and center locking differentials, crawl control, multi-terrain select, and nearly 9 inches of ground clearance, Lexus built something that can genuinely go off-road without hesitation.
If Cadillac wants to compete, it has to match that energy.
That means:
- Real 4WD system, not AWD
- Available locking differentials
- Off-road drive modes and terrain management
- Underbody protection and recovery points
This wouldn’t be a small Escalade-like mall crawler. It would need to be Trailhawk, Bronco Badlands, and Overtrail-level serious.
It Would Blend Real Off-Road Hardware With Cadillac-Level Comfort
This is where Cadillac has to win.
The GX Overtrail already brings a strong mix of capability and comfort, with heated and ventilated seats, a massive 14-inch infotainment screen, a head-up display, and a full suite of driver assistance tech.
Cadillac would need to go further.
Think:
- Super Cruise availability, even in an SUV aimed at off-roading
- Premium materials that feel like Escalade-lite
- A more tech-forward interior layout
- Better on-road ride quality thanks to adaptive suspension tuning
The challenge would be balancing ruggedness with refinement without compromising either.
Timing Is Perfect Because the Market Is Shifting Back to “Real” SUVs
This kind of vehicle wouldn’t exist in a vacuum.
We’re already seeing a clear return to body-on-frame SUVs across the industry, driven by strong demand for capability and authenticity.
Ford nailed it with the Bronco. Toyota continues to dominate with the 4Runner and Land Cruiser. Lexus has the GX. Jeep still owns a huge piece of the market. Even brands like Hyundai and Kia are exploring this space.
GM getting back into it with GMC is one step, but Cadillac joining the fight would be the next logical move.
And honestly, it might be the move that brings a whole new type of buyer into the brand.
Final Thoughts
If Cadillac built a GX 550 Overtrail competitor on the Colorado/Canyon platform, it wouldn’t just be another SUV.
It would be a statement.
The formula already works. Proven truck bones, real off-road hardware, and a premium interior layered on top. Cadillac just needs to execute it in a way that feels distinctly Cadillac.
And if they really want to shake things up?
Give it a V8, give it real capability, and give buyers a reason to look beyond Lexus.
Because right now, that opportunity is wide open.
