1999-2005 UAZ 31625 2.89 (102 Hp)

The UAZ 31625 2.89, producing 102 horsepower, is a Russian off-road vehicle manufactured between 1999 and 2005. Part of the larger UAZ 3162 family, it represents a significant evolution of the iconic UAZ-469, a vehicle originally designed for military use. While not officially sold in the United States, the UAZ 31625 and its predecessors have a substantial following among off-road enthusiasts globally, particularly in Eastern Europe and former Soviet republics. It was designed to provide robust, all-terrain capability at an affordable price point, serving as a workhorse vehicle for both civilian and specialized applications.

UAZ 31625 2.89: A Legacy of Ruggedness

The UAZ 31625 is a direct descendant of a lineage that began in the 1950s with the GAZ-69, and continued with the UAZ-469. The 3162 series aimed to modernize the platform while retaining its core strengths: exceptional off-road performance and durability. The 31625 variant specifically denotes a refinement of the 3162, featuring improvements to the engine, interior, and overall build quality. It was intended to bridge the gap between purely utilitarian vehicles and more comfortable, everyday transportation, though it always prioritized capability over luxury. The vehicle’s design reflects a pragmatic approach to engineering, prioritizing function and reliability over aesthetic concerns.

Engine & Performance

The UAZ 31625 2.89 is powered by a 2.89-liter (176.36 cubic inches) inline four-cylinder gasoline engine. This engine produces 102 horsepower and 211 Nm (155.63 lb.-ft.) of torque at 2800 rpm. While not a powerhouse in terms of raw output, the engine’s torque characteristics are well-suited to off-road driving, providing sufficient low-end grunt for navigating challenging terrain. The engine is longitudinally mounted and utilizes a multi-port fuel injection system. The power-to-weight ratio of 19.8 kg/Hp (50.5 Hp/tonne) and torque-to-weight ratio of 9.6 kg/Nm (104.5 Nm/tonne) contribute to its respectable, if not blistering, performance. The vehicle has a maximum speed of 140 km/h (86.99 mph). The engine’s simplicity and robust construction contribute to its reliability, even under harsh operating conditions. It features an Overhead Camshaft (OHC) valvetrain with 2 valves per cylinder.

Design & Features

The UAZ 31625 is a five-door, seven-seat off-road vehicle. Its body-on-frame construction provides exceptional strength and durability, essential for tackling rough terrain. The vehicle’s design is distinctly utilitarian, with a boxy shape and minimal ornamentation. This design prioritizes practicality and ease of maintenance. The interior is spartan but functional, offering ample space for passengers and cargo. Key features include a part-time four-wheel-drive system with high and low range gearing, allowing for exceptional traction in a variety of conditions. The suspension utilizes a trailing arm setup at the front and a leaf spring arrangement at the rear, providing a comfortable ride on and off-road. Safety features, while limited by the vehicle’s age and intended market, include an Anti-lock Braking System (ABS). The vehicle’s high ground clearance and short wheelbase contribute to its impressive off-road capability. The 90-liter (23.78 US gal) fuel tank provides a substantial range for extended journeys.
