The Isuzu Trooper 3.5 i V6 24V Wagon, produced between 1998 and 2003, represented a significant iteration of Isuzu’s popular SUV. This model, part of the second-generation Trooper (UB series), aimed to blend off-road capability with on-road comfort, targeting families and drivers seeking a versatile vehicle. In the North American market, where the Trooper competed with vehicles like the Ford Explorer and Jeep Grand Cherokee, the 3.5L V6 automatic configuration was positioned as a mid-to-upper range offering, providing a balance between performance and convenience. It was sold under different names in different markets, including the Bighorn in Europe and Australia.

Powertrain & Engine Architecture
The heart of the 3.5 i Trooper was the 6VE1 engine, a 3.5-liter, 24-valve V6. This engine utilized a 90-degree V-angle, contributing to a smoother power delivery. The 6VE1 featured multi-port fuel injection, delivering fuel directly to each intake port for improved combustion efficiency. The double overhead camshaft (DOHC) valvetrain, with four valves per cylinder, further enhanced breathing and high-rpm performance. The engine’s 9.1:1 compression ratio was a compromise between performance and the ability to run on readily available gasoline grades. Paired with this engine was a four-speed automatic transmission, designed for ease of use and comfortable cruising. This transmission wasn’t known for being particularly sporty, prioritizing smooth shifts over aggressive downshifts.
Driving Characteristics
The 215 horsepower and 312 Nm (230 lb-ft) of torque provided by the 3.5L V6 and automatic transmission delivered adequate, though not exhilarating, performance. Acceleration from 0-60 mph took around 9.1 seconds, making it competitive within its class. The automatic transmission, while convenient, did result in some power loss compared to the available five-speed manual. The gear ratios were tuned for everyday driving, offering reasonable acceleration in most situations. However, passing maneuvers at highway speeds required careful planning. The all-wheel-drive system provided enhanced traction in various conditions, making the Trooper a capable vehicle for inclement weather and light off-road use. The vehicle’s weight, approximately 4,500 pounds, was noticeable, particularly during braking and cornering.
Equipment & Trim Levels
The 3.5 i Wagon trim typically included features such as air conditioning, power windows and locks, and an upgraded audio system. Higher trim levels added amenities like leather upholstery, a sunroof, and alloy wheels. Safety features included ABS brakes and, depending on the year and market, optional airbags. Interior appointments were generally functional and durable, prioritizing practicality over luxury. The rear seats offered decent legroom, and the folding rear seats expanded cargo capacity significantly, from 42.02 cubic feet with the seats up to 96.97 cubic feet with them folded down.
Chassis & Braking
The Trooper utilized a body-on-frame construction, providing robustness and off-road capability. The front suspension employed torsion bars, while the rear featured coil springs. This setup offered a comfortable ride, though it wasn’t as refined as the independent suspension systems found in some competing SUVs. Braking duties were handled by ventilated discs at the front and solid discs at the rear. The ABS system helped to maintain steering control during hard braking. The steering was hydraulic power-assisted, providing reasonable feedback and ease of maneuverability.
Market Reception & Comparison
The Isuzu Trooper 3.5 i V6 Automatic received mixed reviews. Critics praised its spacious interior, all-wheel-drive capability, and comfortable ride. However, the automatic transmission was often criticized for its lack of responsiveness and the engine’s fuel economy was considered relatively poor, averaging around 15 mpg in combined driving. Compared to the manual transmission versions, the automatic models offered less engaging driving experience. Against competitors like the Ford Explorer and Jeep Grand Cherokee, the Trooper offered a unique blend of features and value, but its lower brand recognition hindered its sales success in the US market.
Legacy
The Isuzu Trooper 3.5 i V6 Automatic has developed a reputation for reasonable reliability, although maintenance can be costly due to the vehicle’s age and the potential for issues with the automatic transmission. The 6VE1 engine is generally considered durable, but regular maintenance, including timing belt replacement, is crucial. Today, these Troopers are found primarily as affordable used vehicles, appealing to buyers seeking a capable and spacious SUV for light off-road use or as a daily driver. Parts availability can be a challenge, but a dedicated community of owners and online resources help to keep these vehicles on the road.
