The 911 S, introduced in 1967, was a potent Porsche and a marked improvement over its less-powerful 1966 predecessor. Porsche’s new all-aluminum, single-overhead-cam, dry-sumped, 2.0-liter engine boasted a forged steel crankshaft, forged light alloy pistons, and soft nitride-forged steel connecting rods. Breathing through a larger 42-millimeter intake, 38-millimeter exhaust valves, and a pair of 40IDS Weber triple-throat carburetors, the Type 901/02 powerplant gave a solid 160 brake horsepower. The 911 S also had upgraded brakes with ventilated discs, Koni shocks, a rear anti-roll bar, and a set of handsome and lightweight Fuchs forged alloy wheels.

The 911 “Super” was indeed just that—it was capable of reaching 140 mph in fifth gear. By 1967, Porsche owners were winning amateur races on a regular basis. When the SCCA announced a professional racing series for sedans, the hotly competitive Trans-American Sedan Championship, Porsche pounced on a loophole in the rules that allowed it to compete in the Trans-Am’s Under-Two-Liter category. Coming away with the 1967 U2 Series Championship, Porsche proved it was capable of not only defeating rivals like Alfa Romeo and other small sedans and coupes but also larger five-liter Mustangs, Camaros, and Chrysler products as well, especially on tight circuits where nimble handling was paramount.

The exceptional 911 S offered here, chassis number 307557, was, according to its original Kardex (a copy of which is on file), built on February 9, 1967, and delivered on July 20 to the dealers Schmidt & Koch of Bremen, Germany. It was then sold to its original owner, Ralph Mosher, then stationed with the U.S. Army at Bremerhaven. According to research by the McCaw Collection, Mr. Mosher was a robotics engineer who, at the time that he acquired this 911, was developing the GE Walking Truck, a robot activated by human motion, in conjunction with the military. The Porsche returned to the U.S. with Mr. Mosher and was twice serviced at V.W. Pacific in 1967.

The car has been refinished in the original color, Sandbeige, and is still correctly optioned, as-original, with rubber bumper overriders front and rear, tinted windows, seatbelts to both front seats, Blaupunkt Frankfurt radio with one speaker, hazard lights, and, most importantly, the rare sliding Webasto metal sunroof. Its restoration is flawless and excellent in every possible regard, including engine bay, underside, interior, and exterior, all of which is jewelry-like in its quality and attention to detail; even the jack, spare, and tool kit are included. The original engine has turned 46,066 miles at the time of cataloguing.

Certainly one of the most superlative examples of the 911 S that RM Sotheby’s has had the pleasure of offering, this car is a standout even among its great Porsche brethren.
