Tipping the scales at just 545 kilograms, the Spyder took lightweight construction to the extreme. The foam-reinforced plastic body was an incredibly light twelve kilograms. The driver and engine were positioned further forward, to improve the weight distribution. The factory team only competed in the 908/3 Spyder on four occasions but notched up three wins, including on its debut in the 1970 Targa Florio in Sicily, with Jo Siffert and Brian Redman at the wheel.
