The Isuzu Trooper 3.5 V6 24V, produced between 2000 and 2002, 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 refinement, targeting a market increasingly demanding both. In North America, where the Trooper was also sold as the Acura SLX (early models), it competed with vehicles like the Ford Explorer, Jeep Grand Cherokee, and Toyota 4Runner. The 3.5L V6 variant occupied a mid-to-upper position in the Trooper lineup, offering more power and a more premium experience than the base four-cylinder models, but remaining more accessible than potential future high-performance or luxury trims.

Powertrain & Engine Architecture
The heart of the 2000-2002 Isuzu Trooper 3.5 V6 was the 6VE1 engine, a 3.5-liter naturally aspirated V6. This engine featured a 60-degree V-angle, contributing to a relatively compact engine bay layout. The 6VE1 utilized a multi-port fuel injection system, delivering fuel directly to each intake port for improved combustion efficiency. The engine employed a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, enhancing breathing and contributing to the 215 horsepower output at 5400 rpm and 312 Nm (230 lb-ft) of torque at 3000 rpm. The five-speed manual transmission was the standard offering, providing drivers with direct control over gear selection. The transmission was chosen for its durability and suitability for both on and off-road driving.
Driving Characteristics
The 3.5L V6 Trooper offered a noticeable step up in performance compared to the base four-cylinder models. Acceleration to 60 mph took approximately 10.7 seconds, making it competitive within its class. The engine delivered a broad torque curve, providing adequate pulling power for towing and navigating challenging terrain. The manual transmission allowed for precise gear changes, enhancing driver engagement. While not a sports car, the Trooper 3.5 V6 provided a comfortable and capable driving experience, balancing on-road manners with off-road prowess. The 4×4 system, typically selectable between 2WD, 4HI, and 4LO, provided enhanced traction in various conditions.
Equipment & Trim Levels
The 3.5 V6 Trooper typically came with a reasonable level of standard equipment. This included air conditioning, power windows and locks, and an AM/FM stereo. Higher trim levels often added features such as leather upholstery, a sunroof, upgraded audio systems, and alloy wheels. Interior appointments were generally functional and durable, prioritizing practicality over outright luxury. The dashboard layout was straightforward, with clearly labeled controls.
Chassis & Braking
The Trooper’s chassis featured a body-on-frame construction, providing robust durability and off-road capability. Front suspension utilized a torsion bar setup, while the rear employed coil springs. This configuration aimed to balance ride comfort with load-carrying capacity. Braking duties were handled by ventilated discs at the front and solid discs at the rear. An anti-lock braking system (ABS) was standard, enhancing safety during emergency stops. The P245/70 R16 tires provided a good compromise between on-road grip and off-road traction.
Market Reception & Comparison
The Isuzu Trooper 3.5 V6 was generally well-received by automotive critics, who praised its capable engine, comfortable ride, and robust 4×4 system. However, some reviewers noted that its interior design was somewhat dated compared to newer competitors. Fuel economy, at around 12.3 mpg in the city and 21.4 mpg on the highway, was typical for a vehicle of its size and class. Compared to the four-cylinder Trooper, the 3.5 V6 offered significantly more power and refinement, justifying the higher price tag. Against rivals like the Ford Explorer and Jeep Grand Cherokee, the Trooper offered a unique blend of Japanese reliability and off-road capability.
Legacy
The Isuzu Trooper 3.5 V6 has developed a reputation for reasonable reliability, particularly when properly maintained. The 6VE1 engine is generally considered durable, although routine maintenance, such as timing belt replacement, is crucial. In the used car market, these Troopers represent a relatively affordable option for those seeking a capable and reliable SUV. While not as common as some of its American or Japanese competitors, the Trooper 3.5 V6 remains a popular choice among enthusiasts and those looking for a rugged and dependable vehicle. Parts availability can sometimes be a challenge, but a dedicated community of owners and online resources help to mitigate this issue.
