Subaru Rex: A Comprehensive Guide

Introduction

The Subaru Rex, also known as the Subaru Ace in some export markets, was a kei car (Japanese: 軽自動車, keijidōsha, "light automobile") manufactured from 1972 to 1992 by Subaru. Intended as a replacement for the Subaru R-2, the Rex retained a similar philosophy of compact dimensions and economical running. Over its lifespan, the Rex evolved from a rear-engine, rear-wheel-drive platform to a front-engine, front-wheel-drive (and later all-wheel-drive) configuration, reflecting the changing trends in automotive design and engineering. The Rex played a crucial role in Subaru's history, offering affordable transportation for Japanese consumers and establishing the brand's reputation for practicality and innovation.

Generations

  • First Generation (1972-1981):
    • Introduced as a rear-engine, rear-wheel-drive kei car.
    • Powered by a two-stroke, two-cylinder engine initially, later updated to a four-stroke engine.
    • Distinctive styling with a boxy silhouette and round headlights.
    • Notable for its simple construction and affordability.
  • Second Generation (1981-1992):
    • Shifted to a front-engine, front-wheel-drive layout in 1982 (introduced as the Rex Combi).
    • Offered in various body styles including hatchback, sedan, and van (Combi).
    • Improved fuel efficiency and interior space compared to the first generation.
    • Available with optional four-wheel drive, increasing its appeal in rural areas.
    • Featured more modern styling, evolving throughout its production run with updates to the front fascia and interior.

Reliability & Common Issues

The Subaru Rex, particularly earlier generations, is known for its simplicity, which contributes to its reliability. However, given the age of most Rexes on the road today, certain issues are common. It's important to note that parts availability can be a challenge, particularly for specific components related to the rear-engine models.

First Generation (1972-1981) - Rear-Engine Models

  • Engine Overheating: The rear-engine layout can contribute to overheating issues, especially if the cooling system is not properly maintained. Inspect for leaks, blockages, and proper fan operation.
  • Two-Stroke Engine Problems (Early Models): Models equipped with two-stroke engines may experience issues related to oil mixing and carbon buildup. Ensuring proper oil injection and occasional decarbonizing are crucial.
  • Rust: Rust is a significant concern, particularly in areas with road salt. Check thoroughly around wheel arches, floor pans, and suspension components.
  • Electrical Issues: Wiring can become brittle with age, leading to shorts and malfunctions.
  • Carburetor Problems: Carburetors can become clogged or require adjustment.

Second Generation (1981-1992) - Front-Engine Models

  • Engine Wear: As with any older car, engine wear is a factor. Listen for unusual noises and check for excessive oil consumption.
  • Rust: Similar to the first generation, rust is a significant concern, particularly in areas prone to corrosion. Pay close attention to the rear of the car where water can accumulate, and the front around the strut towers.
  • CV Joint Wear (FWD and 4WD): Check for clicking or popping noises during turns, indicating worn CV joints. This is more common on 4WD models due to the added stress on the drivetrain.
  • Four-Wheel Drive System Issues (4WD Models): Inspect the operation of the four-wheel-drive system. Ensure it engages and disengages smoothly. Check for leaks from the transfer case and rear differential.
  • Clutch Wear: Check the clutch for slippage, especially on models with higher mileage.
  • Brake System: Inspect all brake components, including lines, pads, rotors, and calipers, for wear, leaks, and corrosion.

General Considerations:

  • Maintenance Records: Look for well-maintained examples with documented service history.
  • Parts Availability: Be aware that parts for the Subaru Rex can be difficult to find, especially for specific models and years.
  • Specialist Knowledge: Consider consulting with a mechanic familiar with classic Japanese cars for a thorough inspection.

Driving Experience

The Subaru Rex offers a unique driving experience characterized by its small size and nimble handling. However, it's important to manage expectations, as these cars were designed for economy and practicality, not performance. The driving experience varies between the rear-engine and front-engine generations.

First Generation (Rear-Engine)

The rear-engine layout provides a distinct driving feel, with good traction in dry conditions but potential for oversteer in slippery conditions. The small engine delivers adequate power for city driving, but acceleration is limited. The ride can be somewhat bumpy due to the short wheelbase and basic suspension. The cabin can be noisy, especially at higher speeds.

Second Generation (Front-Engine)

The front-engine layout offers more predictable handling compared to the rear-engine models. The improved suspension and longer wheelbase provide a more comfortable ride. The interior is more spacious and refined. The available four-wheel-drive system enhances traction in adverse weather conditions. However, power remains limited, and the Rex is not ideally suited for long highway journeys.

Pros:

  • Compact size for easy maneuvering and parking.
  • Economical fuel consumption.
  • Unique and charming character.
  • Potentially good value for a classic car.

Cons:

  • Limited power and performance.
  • Potential for rust and mechanical issues.
  • Parts availability can be challenging.
  • Ride quality can be harsh, particularly in earlier models.
  • Not ideal for long distances or high-speed driving.

Buying Advice

Purchasing a Subaru Rex requires careful consideration, especially given its age and potential for maintenance issues. Here's some advice to help you make an informed decision:

  • Condition is Key: Prioritize finding a Rex in the best possible condition. Rust repair can be expensive, so look for examples with minimal corrosion.
  • Check for Documentation: Service records and original documentation can provide valuable insights into the car's history and maintenance.
  • Test Drive Thoroughly: Take the car for an extended test drive to assess its performance, handling, and overall condition. Pay attention to any unusual noises or vibrations.
  • Consider the Intended Use: Think about how you plan to use the Rex. If you're looking for a daily driver, a later model with front-wheel drive and improved features might be more suitable. If you're looking for a classic car for occasional use, an earlier rear-engine model could be a rewarding project.
  • Be Realistic About Costs: Factor in the potential for repairs and maintenance. Set aside a budget for unexpected expenses.
  • Join a Community: Connect with other Subaru Rex owners and enthusiasts. They can provide valuable advice, support, and access to parts.

What Years to Look For:

  • Later Second Generation Models (1988-1992): These models typically have more refined features, improved reliability, and better parts availability compared to earlier models. The introduction of the Supercharger offered models with much improved performance.
  • 4WD Models (Second Generation): If you live in an area with harsh weather conditions, a four-wheel-drive Rex can provide added traction and stability.

What to Avoid:

  • Extremely Rusted Examples: Extensive rust repair can be costly and time-consuming.
  • Cars with Significant Mechanical Issues: Unless you're a skilled mechanic and willing to invest significant time and effort, avoid cars with major engine, transmission, or suspension problems.
  • Cars with Missing Parts: Sourcing replacement parts for the Subaru Rex can be challenging. Avoid cars with missing or damaged components that are difficult to replace.

By following these guidelines, you can increase your chances of finding a Subaru Rex that provides years of enjoyment and appreciate the unique charm of this classic Japanese kei car.
