Engine Type:
Inline-4 Cylinder, DOHC (Dual Overhead Camshaft)
Engine Displacement Liters:
Typically 1.6L, 1.8L, 2.0L, and potentially 2.5L V6 for later or specific markets. The 1981 model would most commonly feature the 1.6L, 1.8L, or 2.0L Twin Cam units.
Horsepower Range Ps:
Varies by displacement, typically ranging from approximately 108 PS (1.6L) to 130 PS (2.0L Twin Cam).
Torque Range Nm:
Varies by displacement, typically ranging from approximately 137 Nm (1.6L) to 170 Nm (2.0L Twin Cam).
Fuel Delivery:
Primarily Carbureted (e.g., Weber twin-choke) for 1.6L and 1.8L. Fuel Injection (Bosch L-Jetronic) was common on the 2.0L Twin Cam variants, especially in later models or specific markets.
Ignition Type:
Distributor-based ignition system, likely with electronic ignition control on later models.
Cooling Type:
Water-cooled, pressurized system with thermostat.
Crash Test Data:
Limited readily available official crash test data for this specific year and model from modern standards. Emphasis was on passive safety features of the era.
Braking System:
Four-wheel disc brakes, often with a split hydraulic system for redundancy.
Steering Features:
Recirculating ball steering system, with optional power assistance.
Seat Belts:
Three-point seat belts were standard in the front, with lap belts often in the rear.
Body Construction:
Unitary body construction with crumple zones designed for the era.
Original System:
Basic AM/FM radio, often with cassette player on later models. Speaker placement was typically in the doors or rear parcel shelf.
Driver Aids:
Very limited by modern standards. ABS was not common on this model. Emphasis was on mechanical feedback and driver engagement.
Connectivity Features:
None by modern definition. Limited to basic automotive electrical systems.
Oil Change Interval Km:
Typically 5,000 - 7,500 km, or as specified in the original manual for the specific engine variant.
Tune Up Interval Km:
Spark plug replacement and ignition timing checks typically every 15,000 - 20,000 km.
Engine Oil Type:
API SE/SF rated, SAE 20W-50 or 10W-40 depending on climate. Refer to manual for exact specifications.
Coolant Type:
Ethylene glycol-based antifreeze, typically a 50/50 mix with distilled water.
Transmission Fluid Type:
GL-4 gear oil, SAE 75W-90 or 80W-90. Exact specification critical for transaxle longevity.
Brake Fluid Type:
DOT 3 or DOT 4 hydraulic brake fluid.
Engine Wear:
Valve stem seals can degrade leading to oil consumption. Timing belt on Twin Cam engines requires regular replacement.
Rust Corrosion:
Common for European cars of this era, particularly in wheel arches, sills, and door bottoms.
Electrical Gremlins:
Wiring harnesses and connectors can degrade over time, leading to intermittent electrical faults.
Carburetor Tuning:
Carburetors require periodic adjustment and cleaning for optimal performance.
Automotive Press Acclaim:
The Alfetta was generally praised by the automotive press for its handling, braking, and sporting character, often lauded for its advanced engineering (transaxle, De Dion rear axle) and driver engagement.
