The Porsche 916 was intended as a more luxurious and powerful replacement to the 914, inspired by the highly modified 914 GT that placed sixth overall at Le Mans in 1970. It was to be a direct competitor to Ferrari's 245 Dino, but only eleven prototypes were built before the program was canceled due to escalating costs.
The Porsche 914 was a collaborative project between Volkswagen and Porsche that began during the late 1960s when both manufacturers were looking for a new model. Ford Porsche, it was their entry-level 912 that was being phased out, while Volkswagen was seeking a new range-topping sports coupe to replace its Type 34 Karmann Ghia coupe. A new entity was created in 1969 on an informal (handshake) agreement between Porsche executive Ferdinand Piëch and Volkswagen's Heinz Nordhoff for the creation of a new entry-level mid-engined four-cylinder sports car with a Volkswagen badge. The Porsche version would be an up-market model equipped with a mild 2.0-liter flat six-cylinder engine. Development costs would be shared for budgetary purposes.
When Nordhoff passed away unexpectedly, his successor, Kurt Lotz, did not honor the verbal agreement between Volkswagen and Porsche. He believed that Volkswagen had all rights to the model, had invested considerably in the tooling expenses, and had little incentive to share it with Porsche. This led to the Porsche 914/6 being more expensive than planned, nearly reaching the cost of the 911T, Porsche's next lowest-priced car.
A total of 3,351 examples of the 914/6 variant were built before it was discontinued in 1972. Production of the 914 (Type 914/4) ended in 1974 and it became the company's top seller during its model run, with over 118,000 units sold worldwide (figures include the 914/4 and 914/6).
The Volkswagen/Porsche 914 was introduced in September 1969 at the Frankfurt Motor Show as the first German-built, series-produced mid-engined sports car.
The Porsche 916
The 1971 Paris Auto Show was the intended location for the unveiling of the first 916 prototype, but two weeks before the event, the entire project was canceled due to escalating costs. An additional ten pre-production examples had either been finished or were nearing completion. Five of these prototypes were later sold privately, and the other five were sold to friends and management of the company. It is believed that all of the 916 Prototypes survive, with several residing within the Porsche-Piëch families.
The first prototype, nicknamed 'Brutus,' went to Piëch, who gave the car to his wife. It was powered by a 2.9-liter RSR engine producing 245 horsepower.
Development
Using a standard 914 tub manufactured by Karmann, a new steel roof panel was welded by Baur, in lieu of the removable plastic top of the production cars. Baur strengthened the chassis by adding reinforcement plates to cope with the more powerful engine. Like the factory's 914/6 GT race cars, a set of steel flares were added to the front and rear fenders to house the larger wheels and tires. The fascias (front and rear) were of molded fiberglass modeled on those used on the 914-6 GT, with the ose containing a lip spoiler. There were recessed driving lamps and ducting for an extra oil radiator.
Engine
The Porsche 916 was intended to carry a 2.6-liter engine - for the United States, it would be a Type 911/56, while the European market would receive the 911/86. The first three 916 prototypes created received the 2.4-liter 911 S engine which produced 190 horsepower. Later cars received the 2.7-liter engine, producing 210 horsepower.
Performance
With the 210 horsepower engine and weighing approximately 165 pounds less than a 911 S, the 916 could sprint from zero to sixty mph in under seven seconds, making it the fastest-accelerating Porsche of its era.
Demise
The Porsche 916 development was too expensive since bodywork had to be purchased from Karmann and modifications from Baur. Had the Porsche 916 entered production, it would have been more expensive than the 911 S, making it the most expensive in Porsche's fleet.
