Crash Test Info:
Limited crash test data available for this era and model, generally not subject to modern stringent regulations.
Braking System:
Front ventilated discs, rear drums. Some later models may feature rear discs.
Seatbelts:
Standard front seatbelts, rear optional or lap belts.
Body Structure:
Designed with crumple zones common for the period.

Basic AM/FM radio and cassette player, often with dashboard-mounted speakers. Advanced infotainment systems were not available.
ABS Availability:
ABS was not a standard feature, and may have been an option on very late models, but is exceptionally rare.
Connectivity Features:
None. Designed for mechanical engagement, not digital integration.
Oil Change:
Typically every 7,500-10,000 km (4,500-6,000 miles) or 6-12 months.
Timing Belt Replacement:
Crucial for boxer engines. Typically every 40,000-60,000 km (25,000-37,000 miles) or 3-4 years. Non-compliance risks severe engine damage due to non-interference design.
Engine Oil:
API SG/SH, SAE 10W-40 or 15W-50 (viscosity dependent on climate). Check specific engine recommendation.
Coolant:
Ethylene glycol-based antifreeze, typically a 50/50 mix with distilled water. Specific type may vary; refer to manual.
Transmission Fluid:
GL-4 gear oil, SAE 75W-90 or 80W-90. Check manual for specific requirements.
Rust Corrosion:
Significant susceptibility to rust, particularly in wheel arches, sills, and rear suspension mounting points. Alfasud roots inherited this trait.
Electrical Gremlins:
Older Italian car wiring can be prone to deterioration and intermittent faults. Lucas components were sometimes used, contributing to this reputation.
Carburetor Tuning:
Carburetors require regular adjustment and synchronization for optimal performance and fuel economy.
Rear Suspension Mounts:
The mounting points for the rear torsion bars and suspension can corrode and weaken, requiring structural repair.
Brand Philosophy:
Alfa Romeo is renowned for its sporting heritage, distinctive Italian design, and engaging driving dynamics, often referred to as 'Alfismo'.
