These days, we take it for granted that the Porsche 911 uses a flat-six engine. That's because every version of the iconic rear-engined sports car has had one. Right? Well, for the most part. There was the 912 that joined the original in the late Sixties with a flat-four. And in the mid-Eighties, Porsche toyed around with the idea of a V8-powered 911.

After the first-generation 911 had been in production for over two decades, Porsche began development of its successor, the 964, in the 1980s. And one of its ideas was to use a V8 engine. So it took a 964, borrowed a V8 from Audi, gave it the rear bodywork from a 959 and dubbed it the 965.

The idea was to create a more affordable successor to the 959 that included its advanced all-wheel drive system and active suspension. The Audi V8 would have been replaced with one of Porsche's own design – possibly based on the it had built for Indy racing – but Dr. Ulrich Bez (who was then head of Porsche R&D long before taking the reins at Aston Martin) ultimately killed the project.

That doesn't mean that Porsche has forgotten about the project altogether, as it has just brought one of the prototypes out of its archives to feature in the video below. Enjoy.

      Ruf did a V8 on it's own in a 911 very recently. Kept the weight the same and increased power and TQ. I recall the CG was not affected from a flat 6. I recall it being a 4.5 liter unit with a wide angle in the V. I would have to find the issue of "Excellence" which featured the car to confirm.

        RGT8. Actually had a lower CoG than the flat 6. Porsche continues the 911 with a flat 6 purely for nostalgic reasons, which I admire actually, and which brings in huge profits. why change it? and BTW, Ruf also gets to build proper Boxters\Caymans with their 3800 S. My lotto winnings would be going towards a Ruf for sure.

      Anything with the 959 rear end is awesome. Best looking 911-derived tail ever, IMO. Wish they'd adopted it for the more basic 911s, but in the end its still special.

      I bet cooling was a challenge, but a typical Porsche engineer would likely relish that challenge.

      There was an LSx swapped 996 on BAT for a while about a year or so ago. Looked like a well-done swap.

      The fabled 960. Please Porsche just do one simple thing. Instead of making a $250,000 911 with 600+ hp, could you take the 918, change the styling just a bit and dump a turbo 6 cylinder or 8 cylinder in it and charge about $250,000 for that. 660 hp should do well. Then it can compete against.... Well it's cousin the Lamborghini
