The Porsche 969 was a concept based on the 964 platform intended to succeed the 930 turbo.
The car was conceived in 1982 as a twin-turbo 911 with four-wheel drive and a PDK gearbox. The project received the in-house code 965 and was developed along with the new, 964 generation of the 911. However, the intended engine (a 3,3 litre, 374 hp flat-six) could not be used due to cooling problems. Various alternatives were considered during the car's development, including a water-cooled version of the traditional flat-six and two variants of Porsche's Indy V8 engine.
While the 969 shared the 911's roofline, its slanted headlights and wide tail were carryovers from the 959.
Ultimately, the project was scrapped. Ongoing engine development issues and a projected price of over 200.000 DM in the wake of a recession kept it from succeeding the 911 turbo. (The 964 turbo made its debut in March 1990.) Fifteen of the 16 prototypes were destroyed in December 1988 and the sole remaining prototype has not been seen since.
Saw this post after searching for the 959 thread. I'm surprised Porsche decided to even consider a 959 Mk2, considering how much they cost to build the first go around. Definitely lots of late 80's cocaine era excess all around. I'm glad they didn't make it as it surely would have bankrupted them, considering they sold the 959 for $400,000 USD and still lost money on them back then.
