1986-1988 Porsche 924S
Overview
The 928 introduced Porsche to front-engine sport car development, establishing a new market segment for the marque. Produced from 1978 through 1982, the base 928 employs a 4.5-liter V8 engine producing 219 horsepower in American specification. The front-engine transaxle architecture provided unconventional layout for Porsche, positioning the vehicle as a grand touring alternative to the traditional mid-engine 911. The sedan proportions accommodated four adults in reasonable comfort alongside sports car driving engagement.
The base model with the 4.5-liter V8 addressed grand touring transport demands alongside performance-oriented driving dynamics. The 219 horsepower output delivers adequate acceleration for highway merging and passing scenarios while maintaining acceptable fuel consumption characteristics. The V8 engine provided superior mechanical refinement compared to turbocharged four-cylinder alternatives.
Engineering & Development
The 4.5-liter V8 features an aluminum block with cast iron cylinder liners, employing variable valve timing and port fuel injection. The engine architecture emphasizes smooth power delivery across the operating range. The transmission employs a three-speed automatic unit with torque converter lock-up, enabling efficient highway cruising alongside responsive acceleration.
The suspension maintains independent double-wishbone front and independent multi-link rear configuration with coil springs over telescopic dampers. The transaxle transmission mounting improved weight distribution relative to front-engine designs with front-mounted transmissions. The steering system provides responsive feedback through improved hydraulic assist characteristics.
The braking system specifies ventilated iron rotors with four-piston front calipers and single-piston rear units, providing adequate stopping power. The cooling system incorporates efficient radiator design managing thermal loads from the 4.5-liter displacement.
Market Variants
The base 928 represents entry-level positioning, featuring optional air conditioning and comfort-oriented interior appointments. The leather upholstery serves as optional equipment. The Panoramic sunroof provides enhanced cabin illumination. The wheel specification measures 15 inches as standard, fitted with all-season tires.
The interior emphasizes functional design and practical ergonomics suitable for daily driving and long-distance touring.
Significance
The base 928 establishes Porsche's commitment to front-engine grand touring development, validating that unconventional layout architectures can deliver satisfying driving experiences. The 4.5-liter naturally aspirated V8 demonstrates that moderate horsepower from large displacement delivers refinement and practicality. The model's commercial performance validates continued 928 platform development.
The 928 proved that four-seater grand touring vehicles can maintain sports car driving characteristics despite unconventional layout and seating configuration.
