928GTS 5.4L 1992-95

The Porsche 928 GTS made its debut for sale towards the end of 1991 as a 1992 model in Europe, followed by a spring 1992 release as an early 1993 model in North America. This iteration boasted significant enhancements, including modified bodywork, larger front brakes, and a robust new 5.4L engine generating 350 PS (257 kW/345 hp), marking notable improvements over its predecessors.

Starting in 1987, the Porsche 928 underwent a comprehensive exterior redesign that persisted until the end of its production run in 1995. This overhaul seamlessly integrated the front spoiler into the nose, smoothing the profile to align with contemporary design trends and departing from the angular look of the original models. The rear spoiler evolved into a distinct wing, and side skirts were introduced. Rear tail-light covers were modernized, departing from the inset design of previous models. GTS variants boasted flared rear wheel arches to accommodate wider 9-inch wheels, with two variations of the 17-inch "CUP" wheels available.

After 1986, the 16-valve engine gave way to the Porsche 32-valve 5.0L/5.4L V8, which remained in use until the 928's discontinuation. Alongside the water-cooled V8 engine, Porsche continued employing a transaxle to maintain a balanced 50/50 front/rear weight distribution. Despite its weight, early 928 models performed comparably to contemporary 911s. The body, crafted by Wolfgang Möbius under Anatole Lapine's guidance, utilized aluminum for various components to reduce weight, while the chassis was constructed from galvanized steel. Polyurethane elastic bumpers, integrated into the nose and tail, reduced drag and enhanced visual appeal. The distinctive pop-up headlamps, inspired by the Lamborghini Miura, completed the 928's iconic appearance.

Internally classified as a 2+2, the 928 featured fold-down rear seats to expand luggage space. Although limited by the transmission hump, the rear seats were suitable for short trips or accommodating children. Notable innovations included the adjustable instrument cluster, synchronized with the steering wheel for maximum driver visibility. The 928 also incorporated the "Weissach Axle," enhancing stability during braking and turns. Its engine, featuring an unsleeved, silicon-alloy block made of aluminum, contributed to reduced weight and durable cylinder bore.
