Honda Passport TrailSport vs Jeep Grand Cherokee: Off-Road Torque Vectoring Performance on Rocky Paths
You’re staring down a rocky trail, the kind where choosing the wrong line means scraping your undercarriage or worse — and you’re about to find out if your SUV’s torque-vectoring system is up to the challenge.
Here’s the thing about modern off-road SUVs: they don’t all need locking differentials to get you through tough terrain. The Honda Passport TrailSport and Jeep Grand Cherokee take completely different approaches to sending power to the wheels, and understanding those differences could save you from getting stuck — or help you pick the right vehicle for your adventures.
TL;DR
The Honda Passport TrailSport uses an intelligent torque-vectoring AWD system called i-VTM4 that can send up to 70% of power to the rear wheels and 100% of that to a single wheel with traction. It’s impressively capable for a unibody SUV but lacks a low-range transfer case. The Jeep Grand Cherokee offers more serious off-road hardware with available two-speed transfer cases, air suspension, and up to 100% torque to a single rear wheel, making it the better choice for extreme terrain. For most drivers and moderate trails, the Passport TrailSport is more than enough.
Understanding Torque Vectoring: The Smart Way to Send Power
Torque vectoring sounds complicated, but it’s actually a pretty clever system. Instead of just splitting power evenly between the front and rear wheels, these systems actively decide which wheel needs power most and sends it there .
On a rocky path, that means when one wheel lifts off the ground or starts spinning on loose gravel, the system can redirect power to the wheels that actually have traction. Both the Honda and Jeep do this, but they do it differently — and one is more extreme than the other.
Honda Passport TrailSport: The i-VTM4 System
The Passport’s second-generation i-VTM4 (Intelligent Variable Torque Management) system is Honda’s answer to serious off-road traction. Here’s how it works:
- Up to 70% of total torque can be sent to the rear wheels
- 100% of that rear torque can go to either individual rear wheel
- The system uses two clutches in the rear axle to distribute power side-to-side
- It reacts 30% quicker than the previous generation and handles 40% more torque
In Trail mode, which you select with a physical toggle on the center console, the system reduces traction control intervention, dulls the throttle response for smoother inputs, and makes the AWD system react more quickly to changing conditions .
Real-World Performance on Rocky Terrain
During off-road testing, the Passport TrailSport impressed reviewers with its ability to handle challenging obstacles. Even when a wheel was lifted in the air — which happens with unibody SUVs — the torque-vectoring system worked quickly to send power to the wheels with traction .
One reviewer noted: “Staying on the throttle helped us get up and over a variety of obstacles with ease. Is this the ideal construction for a dedicated off-road vehicle? No. Is it far more capable than the average person is likely going to need? Absolutely” .
The Passport TrailSport offers 8.3 inches of ground clearance with approach and departure angles of 23 degrees and 23.1 degrees respectively . It also features steel skid plates for the engine, transmission, and fuel tank, plus optional rock rails .
Where It Falls Short
The Passport doesn’t have a two-speed transfer case with low range, which means it can struggle on extreme climbs or descents where you need to crawl at very slow speeds. Without low range, the brakes can have a hard time holding the SUV on steep descents, and the front brakes can lock up, causing the vehicle to slide sideways .
For most trails, this isn’t an issue. But for seriously technical rock crawling, it’s a real limitation.
Jeep Grand Cherokee: Quadra-Drive II and Quadra-Trac
Jeep offers three different 4×4 systems for the Grand Cherokee, and the most capable is Quadra-Drive II, which is available on upper trims .
Here’s what makes it different:
- Two-speed transfer case with a low range for serious off-roading
- Rear Electronic Limited Slip Differential that can send up to 100% of available torque to a single rear wheel
- Quadra-Lift Air Suspension that can raise the vehicle for obstacle clearance — up to 10.9 inches in the Trailhawk trim
- Approach angles up to 30.1 degrees — significantly better than the Passport’s 23 degrees
The Grand Cherokee’s Selec-Terrain system offers up to five driving modes, including Rock mode designed specifically for rock-crawling .
The Trailhawk Advantage
If you’re serious about off-roading, the Grand Cherokee Trailhawk is the one to beat. It comes with:
- All-terrain tires
- Two front tow hooks
- Up to 24 inches of water fording capability
- High-strength skid plates for the transfer case, fuel tank, and front suspension
How They Compare on Rocky Trails
| Feature | Honda Passport TrailSport | Jeep Grand Cherokee (Quadra-Drive II) |
|---|---|---|
| Torque to Single Wheel | Up to 100% of rear torque | Up to 100% of total torque |
| Two-Speed Transfer Case | No | Yes |
| Low Range | No | Yes |
| Max Ground Clearance | 8.3 inches | Up to 10.9 inches (Trailhawk) |
| Approach Angle | 23.0 degrees | Up to 30.1 degrees |
| Max Torque to Rear | 70% of total | Variable via transfer case |
| Air Suspension | No | Yes (select trims) |
What these numbers tell you is simple: the Jeep is built for more extreme terrain. The low range alone makes a huge difference when you need to crawl over big rocks or descend steep, uneven hills.
Which One Should You Choose?
Choose the Honda Passport TrailSport if:
- You want a great daily driver that can handle moderate trails
- You value cargo space and interior comfort over extreme off-road capability
- Most of your driving is on pavement, but you want confidence for camping trips
- You don’t want to deal with the complexity (and cost) of air suspension
Choose the Jeep Grand Cherokee if:
- You regularly tackle serious off-road trails
- You want low range for rock crawling and steep descents
- You’re willing to pay more for the most capable off-road SUV in its class
Frequently Asked Questions
What is torque vectoring and why does it matter off-road?
Torque vectoring sends power to the wheels that have traction instead of wasting it on wheels that are spinning. On rocky paths, this helps you keep moving when wheels lift off the ground.
Can the Honda Passport TrailSport handle serious rock crawling?
It can handle moderate rock crawling, but without low range, it struggles on the most extreme terrain. Professional reviewers noted it couldn’t complete their most difficult hill climb tests .
How much torque can the Passport send to a single wheel?
The Passport can send up to 70% of total torque to the rear wheels, and 100% of that amount to either individual rear wheel .
Does the Jeep Grand Cherokee have better off-road angles than the Passport?
Yes. The Grand Cherokee has significantly better approach angles (up to 30.1 degrees vs 23 degrees) and breakover angles, especially when equipped with the air suspension .
Is the Passport TrailSport just for looks or actually capable off-road?
It’s genuinely capable. Reviewers have taken it through challenging trails with deep ruts, rock climbs, and water crossings, and it performed impressively . It’s not just cosmetic, even if it’s aimed at the “rugged-look” market.
What’s the main off-road advantage of the Jeep Grand Cherokee?
The two-speed transfer case with low range is the biggest advantage. It lets you crawl at very slow speeds with precise control, which is essential for serious rock crawling .
Final Thoughts
The Honda Passport TrailSport is a surprisingly capable off-road SUV that can handle more than most owners will ever throw at it. Its i-VTM4 torque-vectoring system is quick and effective, making it feel confident on moderate trails and rocky paths.
But when the terrain gets truly extreme, the Jeep Grand Cherokee’s hardware — low range, air suspension, and more aggressive angles — gives it a clear advantage. The Jeep is the choice for serious off-road enthusiasts.
For everyone else? The Passport TrailSport offers an excellent balance of daily comfort, cargo space, and genuine off-road capability at a reasonable price .
