Porsche 911 1975–1989 car dimensions: 4291 mm long, 1652 mm wide and 1320 mm high. Unladen weight is 1,160 kg. Boot space with the seats up is 160 litres.
The cabin has a classic five-gauge layout with the tachometer in the centre. Air conditioning started as an option and became standard on US models from 1980, with improved vents and controls by 1986. Power windows and a leather-covered steering wheel became standard on later SC and Carrera models. Cruise control was an option from the mid-1970s and standard on some 1989 cars. No electronic driver aids such as cameras or sensors appear in the equipment lists.
The front luggage compartment holds around 160 litres. Rear seats are small but can take extra soft bags when folded.
Payload sits near 205 kg on Turbo models and up to 340 kg on some SC and Carrera versions. No factory towing ratings are listed for this generation. Sport and Turbo Look packages bring thicker anti-roll bars and stiffer suspension for better load handling.
The cabin feels compact and driver-focused with high-backed seats that include integrated headrests as standard. Seating offers solid support for spirited driving. Optional leather upholstery and electric seat adjustments appear on some grades later in the run. Cabin heat comes via exhaust exchangers with electric blowers added for better winter use. Air conditioning becomes available as an option and later standard on certain models. The Targa's removable roof panel lets in open air while keeping a fixed bar for structure. Noise insulation improves over the years for longer trips.
Air-cooled flat-six petrol engines from 2.7 to 3.2 litres
Impact bumpers absorb low-speed hits up to 5 mph without body damage

Fuel comes from rear-mounted air-cooled flat-six engines running on petrol with Bosch injection systems. Consumption figures vary by model and driving but stay in the range typical for the era's performance cars. No complex cooling system means simpler fluid checks overall.
Servicing centres on regular oil and filter changes plus valve adjustments every 12,000 to 15,000 miles. Chain tensioners need inspection at major services. Targa roof seals and heater boxes require attention to prevent leaks. Independent specialists handle most work with good parts availability.
Safety kit starts with impact-absorbing bumpers meeting US 5 mph standards, three-point belts and seats with built-in head restraints. Dual-circuit disc brakes are fitted all round. Galvanising from 1975 preserves body strength and crash integrity over time. No airbags or advanced electronics appear in this generation.
Keeping the car means watching for Targa bar mount corrosion and drying seals. The galvanised body resists rust better than earlier cars. Regular heat exchanger checks avoid exhaust fumes in the cabin. Simple mechanical layout rewards attentive owners with long service life.
