🛡️ Safety Features
Ratings
Crash Test Data:
Limited official crash test data available from the era. Known for its relatively robust safety cage structure and crumple zones for its time.
Passive Features
Safety Cage:
Integral safety cage structure around the occupants.
Seat Belts:
Three-point seat belts (standard on later models, often retrofitted on earlier ones).
Removable Roof Panel:
Targa top design with a removable center roof panel for open-air driving.
Active Features
Brakes:
Four-wheel disc brakes (standard on all models), providing effective stopping power.
💡 Technology Features
Infotainment
Original System:
Basic AM/FM radio, often with a single speaker. Cassette tape players became available later in the production run.
Driver Assistance
Early Features:
No electronic driver assistance systems like ABS, traction control, or airbags. Focus was on pure driving dynamics.
Connectivity
Connectivity Options:
N/A (No provisions for modern connectivity like Bluetooth or USB).
🔧 Maintenance
Service Intervals
Oil Change Interval:
Typically every 3,000-5,000 miles or annually. Specific intervals depend on driving conditions and oil type used.
Tune Up Interval:
Spark plug replacement and ignition system checks every 10,000-15,000 miles. Valve adjustment at similar intervals.
Brake Fluid Flush:
Every 2 years regardless of mileage due to hygroscopic nature.
Fluid Specifications
Engine Oil Type Capacity:
Air-cooled engine, requires specific air-cooled engine oil (e.g., 20W-50 or 10W-30 depending on climate) with approx. 4.5-5.5 liters capacity. The manual would specify exact types and quantities.
Gearbox Oil Type Capacity:
GL-4 gear oil, typically SAE 75W-90 or 80W-90. Capacity approx. 2.5 liters. Manual is crucial for exact spec.
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid.
Known Issues
Rust And Corrosion:
Prone to rust in floor pans, longitudinals, battery tray area, and door sills due to construction and weather sealing. Covered extensively in parts diagrams for replacement panels.
Engine Cooling Issues:
Air-cooled engines can be susceptible to overheating if cooling fins are clogged or if the cooling fan/shrouding is compromised. Parts for fan, shroud, and seals are detailed.
Fuel System Wear:
Aging rubber fuel lines and hoses, diaphragm issues in fuel pumps (mechanical or electric) are common. Parts for these are essential.
Electrical Gremlins:
Older wiring harnesses can degrade, leading to intermittent electrical faults. Fuses, relays, and wiring diagrams are critical and would be referenced in conjunction with this manual.
Targa Top Seals:
Weatherstripping around the Targa top and windows can degrade, leading to leaks. Replacement seals and associated fasteners are detailed.
📚 Vehicle History
Brand Heritage
Parent Company:
Porsche AG
Model Evolution
Development Origin:
A collaboration between Porsche and Volkswagen, intended as an entry-level sports car to fill a gap below the 911. Initially designed by Ferdinand Porsche's son, Ferdinand Alexander Porsche (Butzi).
Engine Options Evolution:
Started with VW-derived 1.7L and 1.8L (VW 411/412) engines, later introduced Porsche-sourced 2.0L (914/2.0) and the much sought-after 2.0L Flat-six (914/6) from the 911T.
Production
Production Period:
1969-1976
Manufacturing Location:
Stuttgart-Zuffenhausen, Germany (assembly by Karmann in Osnabrück for early models, then moved to Porsche's main plant).
Total Units Produced:
Approx. 115,600 units (including VW-branded versions in some markets).
Praised for its handling and unique styling, though often criticized for its VW-derived engines in the 4-cylinder models compared to the more powerful 914/6 variant.
Ratings
Collector Interest:
The 914/6 is highly sought after by collectors and enthusiasts, while well-maintained 914/4 models are also appreciated for their driving experience and classic status.
