1992-1999 Isuzu Trooper (LS) 3.2 i V6 24V (190 Hp) Automatic

The Isuzu Trooper (LS) 3.2 i V6 24V Automatic, produced between 1992 and 1999, represents a significant iteration of Isuzu’s popular SUV. Positioned as a mid-to-upper range trim within the second-generation Trooper lineup (often referred to as the UBS series, and designated as the SJ30/UJ30 series), this variant combined a potent 3.2-liter V6 engine with a four-speed automatic transmission, offering a blend of capability and convenience. The Trooper, in general, was Isuzu’s primary offering in the increasingly popular SUV segment, competing with vehicles like the Toyota 4Runner, Mitsubishi Montero, and Nissan Pathfinder, primarily in markets outside of North America where it was sold under different names and with varying specifications.

Technical Specifications

Powertrain & Engine Architecture

The heart of the Trooper LS 3.2 was the 6VD1 engine, a 3.2-liter, 24-valve, naturally aspirated V6. This engine utilized a cast iron block and aluminum cylinder heads, a common configuration for durability and weight reduction. The 6VD1 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 contributed to the engine’s respectable power output for its time. The four-speed automatic transmission, while not as sophisticated as some contemporary offerings, was known for its robustness and reliability. It provided smooth, if not particularly sporty, shifts. The transmission was electronically controlled, adapting shift points based on throttle position and vehicle speed.

Driving Characteristics

The 3.2L V6 automatic Trooper offered a comfortable and capable driving experience. While not a performance-oriented vehicle, the 190 horsepower and 265 Nm (195 lb-ft) of torque provided adequate power for both on-road cruising and moderate off-road excursions. The automatic transmission, while contributing to ease of use, did result in some power loss compared to the available five-speed manual transmission. Acceleration was reasonable, but not brisk, with a 0-60 mph time estimated around 10-11 seconds. The automatic’s gear ratios were tuned for everyday drivability rather than outright speed. The all-wheel-drive system, typically selectable between 2H (rear-wheel drive), 4H (high-range four-wheel drive), and 4L (low-range four-wheel drive), provided excellent traction in various conditions.

Equipment & Trim Levels

The Trooper LS 3.2 Automatic typically came well-equipped for its era. Standard features often included air conditioning, power windows and locks, a tilt steering wheel, and an upgraded audio system. Interior upholstery was typically cloth, though leather options were available. The LS trim generally offered a more refined interior finish compared to base models. Optional extras could include a sunroof, upgraded sound systems, and alloy wheels. The seven-seat configuration was a key selling point, offering versatility for families. Dashboard configuration was relatively straightforward, prioritizing functionality over flashy design.

Chassis & Braking

The Trooper’s chassis featured a robust body-on-frame construction, providing durability and off-road capability. Suspension consisted of independent double wishbones at the front and a coil-spring setup in the rear. This configuration offered a good balance between ride comfort and handling. Braking duties were handled by ventilated discs on all four wheels, providing adequate stopping power. An Anti-lock Braking System (ABS) was standard on the LS trim, enhancing safety. Hydraulic power steering made maneuvering the relatively large SUV easier. The Trooper’s track width contributed to its stability, both on and off-road.

Market Reception & Comparison

The Isuzu Trooper LS 3.2 Automatic received generally positive reviews, particularly for its spacious interior, comfortable ride, and capable four-wheel-drive system. Critics noted that the automatic transmission slightly diminished the engine’s performance compared to the manual version. Fuel economy, at around 15.9 US mpg combined, was typical for a vehicle of its size and class but was a common point of criticism. Compared to the 3.1-liter V6 manual Trooper, the automatic version offered greater convenience but sacrificed some responsiveness. The 3.2L was also seen as a more refined and powerful option than the earlier 2.8-liter engines offered in the Trooper lineup.

Legacy

The Isuzu Trooper, particularly the 3.2L V6 automatic variant, has developed a reputation for reliability, especially when properly maintained. The 6VD1 engine is known for its durability, and the automatic transmission, while not cutting-edge, has proven to be relatively robust. In the used car market, these Troopers are often sought after by enthusiasts and those looking for a dependable, capable SUV. However, potential buyers should be aware of potential issues such as rust (particularly in areas with harsh winters) and the need for regular maintenance of the four-wheel-drive system. Parts availability can be a concern, though many components are still available through aftermarket suppliers. The Trooper LS 3.2 Automatic remains a testament to Isuzu’s engineering prowess and a popular choice for those seeking a classic SUV with lasting appeal.
