This 911 S displays the steady improvement that Porsche imparted on its highest-performance sports car in the late 1960s and early 1970s. The wheelbase of the 911 had been extended by some 2.5 inches in 1969, providing better balance and handling, and with its engine output now increased to a potent 180 horsepower, thanks to larger valves and better breathing, a larger 225-millimeter clutch was required. Interior fittings were upgraded as well, with a new steering wheel lock and its instruments now mounted in rubber rings. Externally, new door handles of a safer design replaced the earlier pushbutton type, and the cars were delivered with full factory undercoating for the first time.

Stopping power was provided by 11.1-inch ventilated front and 11.4-inch ventilated rear disc brakes, which proved more than enough for a 2,400-pound car. It was also capable of accelerating to 60 mph from a standstill in just over seven seconds and 100 mph in just 20 seconds, as well as reaching a top speed of 144 mph. Few cars of its day were capable of matching its exhilarating performance.

The 911 S offered here is a 1971 model, which means that it is equipped with the aluminum rear deck lid that is unique to this year’s model. It is now finished in its original color combination of Bahia Red with black upholstery, and it is desirably optioned with Recaro Sport seats and a period-correct Becker Europa II radio.

The car was formerly part of a well-known private East Coast collection, and prior to Mr. Mann’s acquisition, it had reportedly received mechanical attention to its transaxle, mechanical fuel injection, and other systems, while also being sparingly driven and enjoyed. It is noted to still have its original engine, and it has been serviced prior to the sale by the noted firm of Pat Williams Racing.

This is the last great Porsche to be owned by a man who loved and knew well the pleasure of air-cooled 911s. At its sale, it will be accompanied by various service and restoration records, an owner’s manual, a tool kit, and its Porsche Certificate of Authenticity.
