The Isuzu Trooper 3.5 V6 24V Automatic, produced between 2000 and 2002, represented a significant iteration of Isuzu’s popular SUV. Positioned as a mid-to-upper range offering within the second-generation Trooper (UBS series), this variant aimed to provide a blend of off-road capability, on-road comfort, and a more powerful engine option compared to the four-cylinder models. It was primarily marketed in North America, Europe, and Australia, competing with vehicles like the Toyota Land Cruiser Prado, Mitsubishi Pajero, and Ford Explorer. This particular configuration, pairing the 3.5-liter V6 engine with a four-speed automatic transmission, was designed to appeal to buyers seeking a more relaxed driving experience without sacrificing the Trooper’s inherent ruggedness.

Powertrain & Engine Architecture
The heart of this Trooper variant is the 6VE1 engine, a 3.5-liter, 24-valve V6. This engine is a naturally aspirated design, utilizing multi-port fuel injection to deliver fuel to each cylinder. The engine’s DOHC (Double Overhead Camshaft) valvetrain contributes to its relatively high output for its displacement. The 6VE1 is known for its robust construction, but also for its potential for oil consumption as it ages. The four-speed automatic transmission, while providing smooth shifts, is a somewhat dated design by modern standards. It lacks the efficiency and responsiveness of newer transmissions with more gears. The transmission was chosen for its durability and ability to handle the engine’s torque in both on- and off-road situations.
Driving Characteristics
The 3.5L V6 Automatic Trooper delivers adequate performance for everyday driving. Acceleration to 60 mph takes around 8.7 seconds, which was competitive for an SUV of its size in the early 2000s. However, it doesn’t offer the brisk acceleration of some of its rivals with more powerful engines. The automatic transmission’s gear ratios are geared more towards cruising and towing than outright performance. Compared to the five-speed manual transmission available on other Trooper models, the automatic feels less engaging and slightly less efficient. The 4×4 system provides good traction in various conditions, making it a capable off-road vehicle, though not as specialized as some dedicated off-roaders.
Equipment & Trim Levels
The 3.5 V6 Automatic Trooper typically came with a reasonable level of standard equipment. This included air conditioning, power windows and locks, a basic audio system, and alloy wheels. Higher trim levels added features like leather upholstery, a sunroof, upgraded audio systems, and woodgrain interior trim. The interior design was functional but not particularly luxurious, reflecting the Trooper’s focus on practicality and durability. Optional extras often included a tow package, allowing for substantial towing capacity, and a rear entertainment system.
Chassis & Braking
The Trooper utilizes a body-on-frame construction, providing a robust and durable chassis. The front suspension employs torsion bars, while the rear features coil springs. This setup offers a good balance between ride comfort and off-road capability. Braking duties are handled by ventilated discs at the front and solid discs at the rear. ABS (Anti-lock Braking System) was standard, enhancing safety during emergency braking situations. The steering is hydraulic power-assisted, providing reasonable feedback and ease of use.
Market Reception & Comparison
The Isuzu Trooper 3.5 V6 Automatic received generally positive reviews, praised for its spacious interior, off-road capability, and comfortable ride. However, critics noted the engine’s relatively modest power output compared to some competitors and the automatic transmission’s lack of refinement. Fuel economy was also a concern, with the 3.5L V6 consuming a significant amount of fuel, especially in urban driving. Compared to the 3.0L V6 and four-cylinder Trooper models, the 3.5L offered a noticeable performance boost but came at the cost of increased fuel consumption and a higher price point. Reliability was generally good, although some owners reported issues with oil consumption as the engine aged.
Legacy
The Isuzu Trooper, particularly the 3.5 V6 Automatic variant, has developed a loyal following among enthusiasts. While not known for being a collector’s item, well-maintained examples are sought after for their ruggedness and off-road capability. The 6VE1 engine, while prone to oil consumption, is generally considered durable and relatively easy to repair. In the used car market, these Troopers represent a relatively affordable option for those seeking a capable and reliable SUV. Parts availability can be a challenge, as Isuzu discontinued sales in the US market in 2008, but a network of aftermarket suppliers and dedicated enthusiasts helps to keep these vehicles on the road.
