Cool find...... 350hp in 1975 was a TON of power......almost exactly what the early Countach and Ferrari BB's had at the time....a true supercar.....even stuck in an audi...

I still think if they built a 5L+ 300hp+ (worldwide) from the very beginning the current Porsche lineup would be drastically different....

I think it's just the author of that article, who didn't bother to really reasearch the subject and listed the specs of GTS there.

here's the google translation.

In the Central Garage in Bad Homburg time was a while ago a very interesting vehicle, part of a Porsche exhibition, shown in. It was the third prototype of the early 70's Porsche 928 in experimental stage The Porsche 928 was produced from 1977 to 1995. Chassis and engine were at the time of a wider body of the Audi 100 Coupe married.

If you have a little preoccupied with the former Audi 100 Coupe, immediately noticed that the show in the exhibition Audi 100 Coupe body was much wider than the then much sought after series coupe from Audi. A normal Audi 100 Coupe looked the other hand, like a reduced copy.

There had been concern at the Audi Coupe body or parts and in the development department modified so that they fit on the chassis of the next Porsche 928th The built V8 engine was 5.4 liters and 350 hp. The current vintage was so suspect a prototype and was able to perform the test runs without being detected by the Erlk÷nig photographers.

The application was the first time from mid-1974. The vehicle was described as V4 V3 is the successor of the test car. That wa the first test bed for the entire drive train, the floor and the front car with wheel arches and axle mounts. Was connected with an automatic transmission. The body was also an Audi 100 Coupe body, but with much wider fenders.

350HP out of that 2-valve motor? Holy Crap, talk about German V8 muscle!

Wonder what it would take to change a US 4.5 to that 5.4?

I think the article is wrong.
I would rather trust Project 928 which reads 5.0L
...which makes a little more sense.

I tend to agree. This would not be the first time a historic Porsche 928 is misrepresented by the Porsche Museum people, and subsequently the press.

I am going to play Devil's advocate regarding the comments the motor is not a 5.4L. Why wouldn't it be? Americans were making big block V8s for muscle cars, so why couldn't the Germans.

Theoretically speaking, they could have scrapped the 5.4L block concept in a street car because of the amount of gas the car would consume. Let's face it, K-Jetronic is not the most economical FI to put on a car. Let's also not forget the 928 was shelved in favor of the 924 due to the Arab Oil Embargo.

Another point, most (if not all) developement references read 5.0L, scaled back later on to 4.5L
It's not that they couldn't have done it... the just didn't.

Ok, it is time to share something then...

The July 1979 issue of Panorama contains an article about V3. It was then in the USA, owned Gerry Sutterfield, a Porsche-Audi dealer. And the car VIN was... 928 001.

And into a Porsche internal document, I have found references to 4 others cars, with VIN 928 002, 928 005, 928 101 and 928 103. It seems that all of them were based on Audi's.
There is also the VIN of V1, based on a Mercedes SL.

...and all of the prototypes had 6 digit VINs. Here is one of the later prototypes...

You are as crazy as I am!
I also try to decipher VIN on such plates, but for the 928 CS prototypes.
Example:

I would appreciate any help. I think that I know the solution, but would appreciate a confirmation.
WP0ZZZ92Z?S84????
The first ? is a H or a J, if that helps.
