UAZ 3151 2.45 (90 Hp)

The UAZ 3151 is a classic Soviet-era off-road vehicle produced by the Ulyanovsky Automobile Plant (UAZ) from 1989 to 2003. A direct descendant of the UAZ-469, itself based on the American Willys Jeep, the 3151 represented a significant modernization while retaining the rugged simplicity and all-terrain capability that made its predecessors legendary. Unlike many vehicles, the 3151 wasn’t designed for a specific consumer market in the West; it was primarily intended for military, agricultural, and general use within the Soviet Union and its satellite states. Its robust construction and four-wheel-drive system made it ideal for the often-challenging road conditions prevalent in those regions. While never officially exported to the United States in large numbers, the UAZ 3151 has gained a cult following among off-road enthusiasts and collectors for its unique character and undeniable capability.

UAZ 3151: A Legacy of Rugged Utility

The UAZ 3151 occupies a unique niche in automotive history. It wasn’t built to compete with passenger cars on comfort or refinement, but rather to provide reliable transportation in the most demanding environments. Its design philosophy prioritized functionality and durability over aesthetics. The 3151’s enduring appeal lies in its simplicity – a characteristic that made it relatively easy to maintain and repair, even in remote locations with limited resources. The vehicle’s body-on-frame construction, coupled with a robust drivetrain, ensured it could withstand considerable abuse. The 3151 served as a workhorse for various sectors, including the military, forestry, and agriculture, and was also popular among civilian users who needed a dependable vehicle for navigating rough terrain.

Engine & Performance

The UAZ 3151 2.45 was typically powered by the ZMZ 4021.10 inline-four cylinder gasoline engine, displacing 2.45 liters (149.51 cubic inches). This engine produced 90 horsepower at 4000 rpm and 172 Nm (126.86 lb.-ft.) of torque at 2200 rpm. While not a powerhouse by modern standards, the engine’s torque output, combined with the vehicle’s low-range gearing, provided ample capability for off-road driving. The engine featured a carburettor fuel injection system, a common technology for the era. The power-to-weight ratio was 18.7 kg/Hp (53.6 Hp/tonne), and the torque-to-weight ratio was 9.8 kg/Nm (102.4 Nm/tonne). The 3151’s top speed was approximately 110 km/h (68.35 mph). Fuel economy was understandably poor, averaging 14.5 l/100 km (16.2 US mpg, 19.5 UK mpg, 6.9 km/l) in urban conditions. The engine required 5.8 liters (6.13 US qt, 5.1 UK qt) of engine oil and 13 liters (13.74 US qt, 11.44 UK qt) of coolant.

Design & Features

The UAZ 3151 is a five-door, seven-seat off-road vehicle with a body-on-frame construction. Its utilitarian design prioritized practicality over aesthetics. The vehicle’s high ground clearance and short wheelbase contributed to its exceptional off-road capability. The body panels are relatively flat and simple, reflecting the vehicle’s functional purpose. The interior was spartan, with basic seating and minimal trim. Features were limited by the vehicle’s intended use and the era in which it was produced. Safety features were rudimentary by modern standards, consisting primarily of a robust chassis and a simple braking system. The 3151’s dimensions are: length 4025 mm (158.46 in), width 1785 mm (70.28 in), height 2050 mm (80.71 in), and wheelbase 2380 mm (93.7 in). The front and rear track are both 1453 mm (57.2 in). The vehicle’s fuel tank capacity is 78 liters (20.61 US gal, 17.16 UK gal).
