Horsepower Range:
80 hp to 150 hp (depending on year, carburation, and turbocharging for Spyder models)
Torque Range:
122 lb-ft to 175 lb-ft (depending on engine variant)
Carburetion:
Single-barrel or twin-barrel Rochester carburetors; optional turbocharging for Spyder models.
Crash Test Era:
Standards and testing methodologies differed significantly from modern standards. No standardized ratings comparable to today's exist.
Brakes:
Four-wheel drum brakes standard. Optional front disc brakes available on later models, particularly Spyder.
Steering:
Optional 'Sim-Thrust' variable-ratio recirculating ball steering system.
Body Construction:
Unibody construction with extensive use of structural bracing, including a ' যoke' or 'Z-bar' crossmember for rigidity, a unique engineering feature.
Seatbelts:
Not standard in early production years; became available as an option or standard on later models.
Oil Change:
Recommended every 3,000 miles or 3 months (using appropriate oil viscosity for air-cooled engines, e.g., SAE 30 or 10W-30 for warmer climates).
Tune Up:
Spark plugs, points, condenser, rotor, distributor cap typically every 10,000-15,000 miles. Ignition timing adjustment is critical.
Valve Adjustment:
Air-cooled engines require periodic valve lash adjustments, typically every 10,000-15,000 miles.
Blower Fan Maintenance:
Regular inspection and cleaning of the cooling fan and shroud system is crucial for engine longevity.
Engine Oil:
API SA or SB service classification oils. SAE 10W-30 or SAE 30 are common recommendations depending on climate. Avoid modern detergents unless specifically formulated for air-cooled engines.
Transmission Fluid:
Manual: GL-4 gear oil. Automatic (Powerglide): Dexron-II or equivalent ATF.
Brake Fluid:
DOT 3 or DOT 4 brake fluid (check specific master cylinder).
Suspension:
Early models had susceptibility to trailing arm bearing failure and potential oversteer characteristics. Later models incorporated improvements.
Cooling:
Overheating can occur if cooling fins are clogged, the fan belt slips, or the fan shroud is damaged/misaligned.
Electrical:
Wiring insulation degradation over time, particularly in high-heat areas. Faulty voltage regulators and generator issues are common.
Fuel System:
Carburetor leaks, fuel line deterioration, and fuel pump issues (if equipped).
Rust:
Corrosion common in floor pans, rocker panels, and around wheel wells due to age and weather exposure.
Manufacturer:
General Motors (GM), Chevrolet Division
Introduction Context:
The Corvair was Chevrolet's first rear-engine, air-cooled passenger car, introduced as a compact car to compete with imported small cars. It was a radical departure from typical American automotive design.
Key Design Influences:
Chief Engineer John DeLorean and designer Larry Shinoda were instrumental in its development.
Body Styles:
Offered in various body styles including 2-door coupe, 4-door sedan, 2-door club coupe, 2-door hardtop coupe, 4-door station wagon, and a sporty Monza Spyder convertible.
Production Period:
1960-1969
Manufacturing Location:
Willow Run, Michigan; St. Louis, Missouri; Tarrytown, New York; Oakland, California
Public Perception:
Infamously targeted by Ralph Nader's book 'Unsafe at Any Speed', which criticized its handling characteristics, although many of these criticisms were more pronounced in early models and addressed in later redesigns.
Automotive Design:
The Corvair's unique styling and engineering received significant attention and acclaim for innovation at its introduction.
Influence:
Considered a landmark in automotive design, influencing subsequent compact car development and rear-engine layouts.
Market Perception Shift:
While critically acclaimed for engineering, its market success was significantly hampered by public perception issues and increased competition, leading to its discontinuation.
