Induction:

Carbureted (Weber/Dell'Orto) or Bosch L-Jetronic/Motronic fuel injection depending on engine and market.

Design:

Dual overhead camshafts driven by a timing belt system. Crucial to follow manufacturer-specified replacement intervals due to interference engine design in many variants.

Common Problems:

Timing belt failure (catastrophic), aging fuel injection systems, carburetor tuning issues, cooling system leaks (especially hose connections), oil leaks from seals.

🔧 Transmission

Type:

5-speed manual transaxle.

Type:

Optional 4-speed automatic (e.g., ZF 4HP22) on some models.

Layout:

Rear transaxle layout, combining gearbox and differential in a single unit at the rear axle for optimal weight distribution.

Gearbox Oil:

Refer to manual for specific API GL-4 or GL-5 gear oil viscosity (e.g., SAE 75W-90 or 80W-90), capacity approximately 2.0-2.5 liters.

Common Problems:

Worn synchros causing difficult shifting, clutch wear, gearbox oil leaks, differential bearing wear.

📐 Dimensions

Curb Weight:

Approximately 1150-1400 kg (2535-3086 lbs) depending on engine and specification.

🛡️ Safety Features

Crash Test Results:

Vehicle safety standards of the era were less stringent than modern times. Specific official crash test ratings are not widely available for this model.

Braking:

Typically front ventilated discs, rear discs. ABS (Anti-lock Braking System) was an optional or standard feature on higher trims or later models.

Restraints:

Seat belts, energy-absorbing steering column (standard for the era). Airbags were not a common feature on early models.

💡 Technology Features

Aging wiring harnesses, corroded connectors, failing relays, and sensor issues are common in older vehicles, leading to various electrical gremlins. Wiring diagrams in the manual are essential.

Rust Perforation:

Common in older European cars, particularly around wheel arches, sills, and floor pans. Inspection and repair are crucial.

Suspension Wear:

Worn bushings, ball joints, tie rod ends, and shock absorbers are common due to age and mileage, affecting handling and ride quality.
