Porsche 928 1987–1995 car dimensions: 4523 mm long, 1836 mm wide and 1282 mm high. Unladen weight is 1,590 kg. Braked towing is 1,600 kg.
The cabin offers a practical 2+2 layout with fully power-adjustable leather front seats that include memory settings for the driver and mirrors on later cars. Automatic climate control is standard and keeps cabin temperature steady. Cruise control is standard from 1988 models onward. Dual airbags arrived as standard in some markets from 1990. Power windows, locks and mirrors are fitted. The centre console holds clear controls and a capable audio system. Rear seats suit children only due to the large transmission tunnel. No modern driver aids like cameras or electronic warnings appear.
The hatchback tailgate opens to a usable 200-litre boot that holds two large bags for daily trips. Folding the rear seats flat expands capacity to 400 litres for longer items. A temporary spare sits under the floor with a storage net available.
Braked towing capacity reaches 1600 kg and unbraked 750 kg with a 75 kg drawbar limit. Payload sits around 330 kg based on 1920 kg gross and 1590 kg curb weights. Sport suspension appears on GT and Club Sport grades. The car suits grand touring rather than heavy work use.
Leather-trimmed seats with multi-way power adjustment come standard and support long drives well. Optional lumbar support and memory functions add convenience. Air conditioning is standard throughout. Later GTS models gain extra sound-proofing for a quieter cabin. The low seating position and clear gauges give a sports car feel with practical folding rear seats for extra space.
Premium unleaded fuel only, 95-98 RON.
Oil and filter change every 12,000 miles or 20,000 km.
Timing belt replacement every 48,000-60,000 miles or 4-6 years.
ABS standard from 1985 across markets.
Driver and passenger airbags standard from 1990 in LHD markets, dual on GTS.
Weissach axle and later PSD for stability.
The engine requires premium unleaded fuel only. Regular oil checks and changes keep the large-capacity V8 reliable over high mileages.
Service the timing belt, water pump and tensioners on schedule as the interference engine risks major damage if the belt fails. Oil changes and fluid checks form the core routine. Automatic transmission fluid needs attention every two years or so.
ABS is standard. Airbags arrived in 1990 for many markets and became dual standard on the GTS. The Weissach rear axle aids stability and the later PSD limited-slip differential further improves grip and control.
Keep the car by following maintenance intervals closely. Rubber parts, seals and cooling components age and need replacement. A full service history protects reliability and value on this generation.
