928S2 4.7L 1984-86

From 1980 (1983 in North America) through 1986, the "S" and "S2" models of the 928 featured integrated front and rear spoilers, seamlessly blending into the fastback design. The original 16v engine continued to evolve until its final iteration in the 1985 model year with the S/S2 model, producing a robust 310 PS (228 kW; 306 hp) in European specification, thanks to enhancements like higher compression, twin distributors with EZK ignition, and Bosch LH-Jetronic fuel injection.

To achieve a balanced 50/50 front/rear weight distribution, Porsche utilized a transaxle alongside the water-cooled V8 engine in the 928, resulting in performance comparable to the contemporary 911, despite its heavier build. By the time the S/S2 specification was in production, the 928 was even outperforming the 911 Turbo in top speed tests.

A four-speed automatic transmission replaced the three-speed option from 1983 in North America and 1984 in other markets. The body, designed by Wolfgang Möbius under the guidance of Anatole Lapine, featured aluminum components for weight reduction, while the underlying chassis was constructed from galvanized steel. Innovations like polyurethane elastic bumpers integrated into the nose and tail, along with distinctive pop-up headlamps inspired by the Lamborghini Miura, contributed to the 928's iconic appearance.

Internally classified as a 2+2, the 928 boasted two small rear seats that could fold down, offering additional space in the luggage area. However, due to the transmission hump, rear seat legroom was limited, primarily suitable for short trips or accommodating children.

The innovative instrument cluster of the 928 moved along with the adjustable steering wheel to ensure optimal visibility for the driver. In 1985, Porsche updated the North American 928 S, replacing the engine with a new 5.0 L DOHC unit sporting four valves per cylinder and producing 215 kW; 292 PS (288 hp). Additional updates included revised suspension settings, larger brakes with 4-piston calipers, and a modified exhaust system in the 1986 928S, marking the final changes to the old body style cars.
