Default 1974 928 Prototype based on Audi Coupe

Many of us have read the stories of the Audi Coupe that was widened in the center, to make room for the powertrain of the upcoming 928.

Tonight I stumbled across an article that includes recent pictures of the car. It confirms my earlier speculations that this car still exists and is hidden away somewhere at Porsche.

Take a look:


According to the arcticle, this one has 5.4 Liters and 350hp.

I would love to see what they did with the suspension on that car!

As well as take it out and flog it at the track!

Wow I figured it would have been a test hack and disassembled!!! Very very cool! Wonder if someone hid it officially or stashed it in some back warehouse because they didn't want to see it destroyed.

Reads it used a 928 suspension, though did not have the Weissach link (per Project 928)

Very cool! It also has one of the early wheel designs for the 928.

Judging from the condition of the engine compartment it appears to have been really used.

That's beautiful. I wonder how many times they redid that engine compartment to rework/tweak the design.

Looking at that engine bay I can't stop thinking about how easy it would be to R&R that coolant expansion tank!

Great find! I wonder if the rear vents on the C-pillars play any functional role or if they are just for decoration...

Yanked some pics and text from Project 928.

V3 (Audi 100 Coupe) became the first vehicle to test the
complete drive line unit in September 1973, using the
platform and front section with altered wheel housings
and suspension location. This car was stretched to the
necessary overall width by bulging fender extensions and
taken on two major African tests as well as a Mont Ventoux
mountain experiment. At the beginning of 1975 it was
converted to automatic gearbox.
V4 (Audi 100 Coupe) didn't receive wider fenders.
Instead it was cut down the middle and widened overall by
4.3 inches. This vehicle had the entire 928 platform, the
five-liter K-Jetronic engine and transaxle with manual
gearbox. It was used in chassis and engine tests from July
of 1974 on.
V5 (Audi 100 Coupe) corresponded in technical basics to
V4 and as of the end of 1974 was used in chassis
experiments, fitted with the ultimate rear axle although it
did not yet have the control link,
Munga was a bare chassis created in November 1973 and
used for engine experiments. It was given the name of
Germany's army jeep in deference to its off-road looks.
This airy vehicle was really only driveable to a limited
extent but testers enjoyed it tremendously around the
Weissach grounds, It had a five-liter carburetor engine
and transaxle with racing gearbox from the 908.03.
Next came those actual 928 prototypes which carried
through the test program, beginning in 1974,
928 K 1 (from January 1974) was the first of all 928...

This pic is from what I believe is the first (of two) African tests. This may be V3.

Don't let those Bozos over at Mythbusters get wind of this or it's a goner.
