A New Contender in South Africa’s Luxury SUV Market
South Africans love tough SUVs. Whether it’s a trip to the Drakensberg, exploring the Karoo, or just navigating pothole-ridden city roads, a capable 4×4 with a luxurious cabin is a must-have for many. Enter the 2025 Lexus GX 550 Overtrail, an SUV that merges rugged adventure DNA with top-tier luxury.
What Makes the GX 550 Overtrail Stand Out?
This isn’t just a rebadged Toyota Prado. While both ride on the TNGA-F ladder-frame platform, the Overtrail variant of the GX 550 brings a different personality to the table — more power, more features, and a whole lot more prestige.

Under the Hood
Engine and Transmission Details
The 3.4L twin-turbo petrol V6 is the star of the show. It’s smooth, powerful, and refined. The 10-speed automatic gearbox is smart, always finding the right gear whether you’re crawling over rocks or overtaking on the N1.
How It Performs on the Road
The GX 550 Overtrail accelerates from 0–100 km/h in just 7 seconds, though many reviewers found it even quicker in real-world conditions. The engine note is addictive — a deep, satisfying growl.
Fuel Consumption Realities
Lexus claims 12.3 L/100km, but real-world driving often creeps past 15 L/100km, especially in urban settings. This is where a twin-turbo V6 shows its thirst. If fuel efficiency matters more to you than power, the Prado’s diesel alternative might be a better bet.
Off-Road Capability
Chassis, Ground Clearance, and Suspension
With 220mm of ground clearance, the Overtrail is ready for serious off-roading. The reinforced underbody protection, e-KDSS suspension, and chunky 18-inch all-terrain tyres all scream “Take me off the beaten path!”
4×4 System and Off-Road Features
The GX 550 includes:
- Multi-Terrain Select (Auto, Dirt, Sand, Mud, Rock, Deep Snow)
- Crawl Control
- Downhill Assist
- Locking Rear and Centre Differentials
What Makes It Adventure-Ready
Unlike the X5 or Q7, the Lexus won’t blink twice at gravel, sand, or rocky terrain. It feels like a Land Cruiser in designer clothes — tough where it matters but elegant where it counts.
Ride and Handling
On-Road Comfort vs. Off-Road Toughness
It’s rare to find a ladder-frame SUV this comfortable. The suspension soaks up bumps, and the well-insulated cabin keeps road noise at bay.
Suspension Setup and Electronic Aids
Thanks to e-KDSS, the GX adapts to terrain automatically. It loosens up for rock climbing and stiffens for sharp tarmac handling.
Steering and Urban Drivability
Though it’s nearly 5 meters long, light steering makes it surprisingly easy to park and maneuver in tight Joburg streets.
Interior and Comfort
Cabin Layout and Design
The dashboard features physical controls (finally!) and a massive 14-inch touchscreen. Everything feels premium — soft leather, suede accents, and thoughtful ergonomics.
Tech and Connectivity
- Apple CarPlay & Android Auto
- Wireless charging
- Multiple USB ports (front and rear)
- Digital instrument cluster
Space and Seating Options
The Overtrail seats five comfortably. If you need more, the SE variant offers seven seats but skips some off-road features.
Practicality and Features
Luggage Capacity and Cargo Flexibility
The boot is spacious at 1,063 litres, with second-row fold-down flexibility. Perfect for camping gear, baby strollers, or your golf clubs.
Everyday Usability
Heated and ventilated seats, multiple climate zones, and smart storage compartments make this a daily-driver dream — even in traffic jams.
How it Compares to Similar SUVs
Compared to the Defender, the GX is smoother. Against the X5, it’s tougher. And versus the Prado, it feels like the same bones, but with a premium wardrobe.
Luxury Without the Complexity
Standard Features Included
What you see is what you get. No complicated packages. No hidden upgrade costs. Only optional extra? A bi-tone exterior paint job for R10,400.
Optional Extras? Very Few
This is refreshing. Unlike German SUVs that drown you in extras, the GX 550 Overtrail comes fully loaded from the get-go.
Safety and Driver Assistance
Advanced Safety Tech
- 8 airbags
- Adaptive Cruise Control
- Lane Keeping Assist
- Blind Spot Monitoring
- Rear Cross-Traffic Alert
Driver Aids in Urban and Off-Road Settings
Whether parking at a mall or crawling over rocky outcrops, the cameras and sensors keep you informed and protected.
