Engine Range:
The Alfa Romeo 75 featured a range of gasoline and diesel engines, including the renowned Alfa Romeo Twin Cam (1.6, 1.8, 2.0) and V6 'Busso' engines (2.5, 3.0). Diesel options included VM Motori units.
Example Engine Performance:
The 2.0 Twin Cam (1.8-liter) typically produced around 128 hp, while the 2.5 V6 'Busso' could output approximately 158 hp.
Injection Carburetion:
Early models utilized carburetors (e.g., Weber twin-choke on 1.6/1.8), with later and higher-performance variants featuring Bosch L-Jetronic or Motronic fuel injection.
Standard Transmission Type:
Rear-wheel drive with a unique transaxle layout (gearbox and differential integrated at the rear axle) for improved weight distribution.
Optional Transmission Type:
Some models offered a 5-speed manual transmission. Automatic transmission options were also available on certain variants.
Clutch Type:
Single dry plate clutch, with specific maintenance and adjustment procedures covered.
Wheelbase:
Approximately 2,510 mm (98.8 in)
Length:
Approximately 4,260 mm (167.7 in)
Width:
Approximately 1,680 mm (66.1 in)
Height:
Approximately 1,370 mm (53.9 in)
Curb Weight:
Varied significantly by engine and trim, typically ranging from 1,100 kg to 1,400 kg (2,425 lbs to 3,086 lbs).
Oil Change Interval:
Typically every 7,500 - 10,000 km (4,500 - 6,000 miles) or 6-12 months, depending on driving conditions and oil type.
Timing Belt Replacement:
Crucial for Twin Cam and V6 engines; intervals generally around 50,000 - 70,000 km (30,000 - 45,000 miles) or 3-5 years. Failure is catastrophic.
Engine Oil Specification:
API SG/SH or ACEA A2/A3; viscosity typically 10W-40 or 15W-50 depending on climate. Specifics for Twin Cam vs. V6 differ.
Coolant Specification:
Ethylene glycol-based antifreeze, mixed 50/50 with distilled water. Specific Alfa Romeo approved coolant recommended.
Brake Fluid Specification:
DOT 3 or DOT 4 brake fluid.
Transmission Fluid Specification:
GL-4 or GL-5 gear oil for manual transmissions and transaxles; specific ATF for automatic transmissions.
Rust Corrosion:
Vulnerable to rust, particularly in wheel arches, sills, and around the battery tray. Good inspection and preventative treatment are essential.
Engine Maintenance:
Timing belt integrity is paramount. Carburetor tuning can be sensitive. V6 engines are robust but require diligent maintenance.
Electrical Reliability:
Older wiring harnesses and connectors can degrade, leading to intermittent electrical faults.
Suspension Components:
Bushings and ball joints can wear over time, affecting handling and ride quality.
Heritage Context:
The 75 continued Alfa Romeo's long-standing tradition of producing sporty, driver-focused sedans with a passion for engineering and performance.
Production Start:
Introduced in 1985 as a replacement for the Alfa Romeo Giulietta (Type 116).
Facelifts Updates:
Received minor updates and facelifts during its production run, including revised styling and interior improvements, notably around 1987 and 1990.
Production End:
Production ceased in 1992, succeeded by the Alfa Romeo 155.
Manufacturing Locations:
Primarily manufactured in Italy.
