1971 Porsche 911 S/T

Porsche developed the S/T, of which 33 were built in 1970 and 1971, taking full advantage of new FIA rules allowing a two-inch wider track.

Accordingly, wheel arches were widened to accommodate seven-inch front and nine-inch rear wheels. Weight reduction was even more radical, including thinner-gauge steel for the roof and floorpans. Heating ducts, seat slide supports, the glove-box lid, ashtray, sun visors and rear torsion-bar covers were deleted.

Transverse bars linked the strut towers, while soundproofing and under-seal were omitted and minimal paint was applied. Plastic front and rear bumpers, a plastic front lid and lightweight Plexiglas side and rear windows were included. The 2.5-litre engine produced 270 bhp, and upgraded ventilated disc brakes, Recaro sport seats and a variety of fuel capacities completed the specification.

Auction Sales History

1971 Porsche 911 S/T

1971 Porsche 911 ST 9111300647Björn Waldegård, the most successful 911 rally driver of the era, amassed high profile wins, including the 1968 Swedish Rally followed by wins at Monte Carlo in 1969 and 1970. The 1971 911 S/T offered here is one of five cars built in January 1971 to contest the East African Safari Rally, and it was driven by Waldegård himself. None of the Porsche entries completed the gruelling event, however, and only four of this group of cars still exist today, with just two still complete. This example, complete with correct 2.5-litre twin-plug racing engine, was authentically and painstakingly restored, retaining its original interior. Auction Source: 2010 RM Auctions Sporting Classics of Monaco
