Transmission Type Standard:
5-speed Manual Transaxle
Transmission Type Optional:
None explicitly mentioned in product description, but some markets may have had automatic options for V6 models.
Drive Layout:
Rear-wheel drive (RWD) with engine and gearbox mounted transversely at the front (transaxle design).
Clutch Type:
Single dry plate, hydraulically operated.
Crash Test Results:
Era-appropriate, likely not subjected to modern rigorous testing. Emphasis on mechanical integrity and driver control.
Brakes:
4-wheel disc brakes, likely with ventilated fronts on performance variants. ABS was an option or standard on later/higher trims.
Handling:
Excellent balance due to RWD and transaxle layout, contributing to active safety.
Seatbelts:
Standard seatbelts.
Body Structure:
Reinforced passenger cell for the era.
Audio System:
Factory fitted radio/cassette player, with upgraded aftermarket options common.
ABS:
Optional on some models, standard on later or higher trims.
Vvt:
Featured on the 2.0L Twin Spark engine, a pioneering application of variable valve timing in production.
Oil Change Interval:
Typically every 5,000 - 10,000 km or 6-12 months, depending on driving conditions and oil type specified in manual.
Timing Belt Replacement:
Crucial for Twin Cam and V6 engines. Interval typically around 60,000 - 80,000 km or 4-5 years. Manual will specify exact interval and procedure.
Engine Oil Type V6 Est:
API SG/SH rated, viscosity like 10W-40 or 20W-50, synthetic or semi-synthetic recommended for modern standards.
Engine Oil Type Twin Spark Est:
Similar to V6, but potentially specific recommendations for Twin Spark system. Manual will be definitive.
Coolant Type:
Ethylene glycol based coolant, mixed with distilled water (e.g., 50/50 ratio). Manual will specify Alfa Romeo's proprietary coolant or compatible types.
Brake Fluid Type:
DOT 3 or DOT 4, low viscosity, high boiling point. Manual will specify.
Transmission Fluid Type:
GL-4 rated gear oil, viscosity typically 75W-90 or 80W-90. Manual will specify exact type and capacity.
Rust Prone Areas:
Wheel arches, sills, door bottoms, rear valence, strut towers. Thorough inspection is critical.
Electrical Gremlins:
Common in older Italian cars, including dashboard issues, intermittent lighting, and sensor failures. Manual's diagnostic section is invaluable.
Engine Reliability V6:
The Busso V6 is generally robust but requires diligent maintenance, especially timing belt changes. Head gasket issues can occur if overheated.
Engine Reliability Twin Spark:
The twin spark ignition system, while advanced, requires proper maintenance of spark plugs and ignition coils. Camshaft wear can be an issue if oil changes are neglected.
Clutch Wear:
Clutch actuation and wear are common maintenance items, especially on spiritedly driven cars.
