Based on the 911S, the 911 R was produced by Porsche to compete in the FIA’s GT 2.0 category. To make it competitive, the 911R was powered by a flat-six engine, Type 901/22 from the Porsche 906, capable of 210 hp. It went on a diet too, with weight savings coming from everywhere, getting the 911 R down to just 1,800 pounds dry. Four prototypes were constructed after which Porsche had coachbuilder Karl Baur build another 20 customer cars. In the end, because of the modifications to the 911R, the FIA refused to homologate the car.
Southern California Porsche dealer Johnny von Neumann knew what his customers wanted, and a Targa top Targa 911 wasn’t it. With Porsche’s approval, he hired designer Nuccio Bertone to create a one-off 1966 Porsche 911 Spyder, in hopes of launching low-volume production. Just one example was constructed.  The engine incorporated a vertically-mounted cooling fan, a 9.1:1 compression ratio and two triple-choke 40PI Solex carburettors. Peak output was 130bhp at 6100rpm and 174lb-ft at 4200rpm. Transmission was via a Type 901 five-speed gearbox and single-plate clutch.
In 1963 Porsche introduced their seminal 901 at the 911 at the Frankfurt Motor Show which would be renamed 911 for the 1964 model year. The new car was sold alongside the 356C as an alternative with more power and room for a rear seat. At the 1963 Frankfurt show the public saw Porsches new direction. Compared to the 356 it had a longer wheelbase, a more compact suspension setup and much more power from the flat-6 engine.
