INEOS Grenadier Review: Off-Road Mastery Tested

The Grenadier's Purpose-Built Philosophy

When billionaire Sir Jim Ratcliffe decided the world needed a proper old-school off-roader, he created the INEOS Grenadier. This isn't another corporate SUV designed by committee. After analyzing Edmunds' comprehensive testing, I believe the Grenadier delivers an uncompromising vision: a body-on-frame, live-axle vehicle channeling classic Land Rover Defender spirit with modern BMW engineering. Tested against industry benchmarks, it reveals fascinating trade-offs between nostalgia and contemporary performance expectations.

Performance Metrics: On-Road Limitations

The Grenadier's BMW-sourced B58 powertrain—a 3.0L turbocharged inline-six paired with an 8-speed automatic—delivers adequate power but falls short in instrumented testing:

0-60 mph: 8.8 seconds (slower than most rivals)
Quarter-mile: 16.6 seconds
60-0 mph braking: 152 feet initially, worsening to 170 feet
Skidpad grip: 0.61 G (limited by aggressive Bridgestone K02 tires)

Why these numbers matter: The detuned engine prioritizes low-RPM torque for off-roading over on-road sprinting. Combined with hydraulic recirculating-ball steering—similar to a Jeep Wrangler—the driving experience feels deliberately old-school. You’ll notice steering slack ("movie steering") and minimal self-centering, requiring constant correction.

Off-Road Dominance Validated

Where the Grenadier redeems itself is off-road. Edmunds' testing proved its capabilities:

Articulation & Protection

Cleared the "ziggurat" obstacle with 10.5 inches of ground clearance
Full underbody skid plates shielding critical components
Locking front/rear differentials (standard with Rugged Pack)

Hill Climb & Traction Control

Conquered steep inclines in 4-low with rear lockers engaged
Torque delivery at 1,700 RPM provided controlled ascent
Key limitation: No disconnecting sway bars like Bronco/Wrangler

Obstacle Course Performance

Navigated pipe obstacles with superior breakover angles
Outperformed Lexus GX and Mercedes G550 on articulation tests
Notable drawback: Awful turning radius and throttle sensitivity

Exclusive Insights: Beyond the Spec Sheet

Build quality surprised positively. Manufactured in a former Mercedes-Benz factory in France, the Grenadier avoids typical startup issues—no creaks or loose trim. The minimalist interior (with aircraft-inspired roof panels) focuses on durability over luxury.

The transmission calibration frustrated testers. Even in manual mode, it upshifts prematurely during aggressive off-roading, requiring constant intervention. This isn’t a dealbreaker but highlights the focus on crawling over high-speed terrain.

Price-to-value analysis: At $83,000 as tested, it lacks modern driver aids but offers extensive customization:

Safari windows
300 lb-rated fender panels
Integrated shovels/roof racks
That charming "toot" horn button

Verdict: Passion Over Practicality

The INEOS Grenadier isn’t the fastest, most comfortable, or tech-laden SUV. But after studying its testing data and design philosophy, I conclude it succeeds brilliantly as a purpose-built off-roader. It makes trade-offs (hydraulic steering, basic interior) to achieve mechanical honesty missing in digitized rivals. For enthusiasts seeking analog adventure, it’s a refreshing alternative—even at a premium price.

Actionable Takeaways

Test the steering yourself—it’s an acquired taste
Prioritize lockers for serious off-roading
Consider tire upgrades if on-road refinement matters
Explore the configurator—customization is a core strength
