The Opel Campo Half Cab 2.3 (94 hp) 4×4, produced between 1991 and 1995, represents a utilitarian offering from Opel aimed at the light commercial and recreational vehicle markets. Positioned as a more affordable and compact alternative to larger pickup trucks, the Campo Half Cab filled a niche for buyers needing a versatile vehicle capable of both work and leisure. It was based on the Isuzu Faster platform, a result of collaboration between Opel and Isuzu, and shared many components with its Japanese counterpart. The “Half Cab” designation refers to the vehicle’s extended cab configuration, offering limited seating for passengers behind the driver and front passenger, differentiating it from the single-cab versions available.

Powertrain & Engine Architecture
The Opel Campo Half Cab 2.3 utilized the 4ZD1 engine, a 2.3-liter inline-four cylinder gasoline engine. This engine, sourced from Isuzu, was a relatively simple design featuring a single overhead camshaft (SOHC) valvetrain and two valves per cylinder. Fuel delivery was managed by a carburetor system, common for vehicles of this era, rather than more advanced fuel injection. The 4ZD1 produced 94 horsepower at 5000 rpm and 170 Nm (125.39 lb-ft) of torque at 2600 rpm. The engine’s design prioritized durability and low-end torque over outright performance. The five-speed manual transmission was the only gearbox option available for this variant, providing a reasonable spread of gears for both on-road and off-road driving. The 4×4 system was typically part-time, requiring the driver to manually engage four-wheel drive when needed.
Driving Characteristics
The Campo 2.3 4×4, with its 94 horsepower and relatively low curb weight, offered adequate, though not exhilarating, performance. Acceleration was modest, and the engine felt strained when pushed hard, particularly when fully loaded. The five-speed manual transmission allowed drivers to keep the engine in its optimal power band, but the lack of overdrive gearing meant that highway cruising could be noisy and fuel-intensive. The part-time four-wheel drive system provided enhanced traction on loose surfaces, making the Campo a capable off-road vehicle for light to moderate terrain. The suspension, while adequate for general use, was tuned for load-carrying capacity rather than ride comfort, resulting in a somewhat firm and bouncy ride, especially when unladen.
Equipment & Trim Levels
The Opel Campo Half Cab 2.3 4×4 was generally sparsely equipped, reflecting its utilitarian nature. Standard features typically included a basic dashboard with analog gauges, vinyl upholstery, and a simple two-speaker audio system. The “Half Cab” configuration provided a small rear bench seat, suitable for occasional passengers or cargo. Optional extras were limited but could include power steering, upgraded audio systems, and a rear window defogger. The interior was designed for practicality and ease of cleaning, with durable materials used throughout. Trim levels were minimal, with most Campos being essentially base models with a few optional accessories added by the buyer.
Chassis & Braking
The Campo Half Cab featured a body-on-frame construction, providing a robust and durable chassis capable of handling significant payloads. The front suspension utilized independent coil springs, offering a degree of ride comfort and handling precision. The rear suspension employed a more traditional dependent leaf spring setup, prioritizing load-carrying capacity and durability. Braking was provided by ventilated discs on the front wheels and drum brakes on the rear. The braking system was adequate for the vehicle’s weight and performance, but lacked the sophistication of more modern braking systems. Steering was typically manual, although power steering was available as an option.
Market Reception & Comparison
The Opel Campo Half Cab 2.3 4×4 was generally well-received in its target market as a practical and affordable pickup truck. Critics praised its durability, off-road capability, and relatively low purchase price. However, it was also criticized for its basic interior, modest performance, and lack of refinement. Compared to other pickups available at the time, such as the Toyota Hilux or Nissan Datsun, the Campo offered a more budget-friendly option, but lacked the same level of sophistication and reliability. Fuel economy was average for a vehicle of its type, and maintenance costs were generally reasonable due to the engine’s simple design.
Legacy
The Opel Campo, and its Isuzu Faster sibling, proved to be a reasonably reliable workhorse for many owners. The 4ZD1 engine, while not particularly powerful, was known for its durability and longevity, provided it was properly maintained. Today, the Campo Half Cab 2.3 4×4 has become a sought-after vehicle among enthusiasts and collectors, particularly those interested in classic Japanese and European pickups. Parts availability can be a challenge, but many components are interchangeable with those from the Isuzu Faster. Well-maintained examples command a modest but growing value in the used car market, appealing to those seeking a simple, rugged, and affordable vehicle with a unique character.
