1300 GTA Gruppe 2 Hahn Mannheim

Does anyone have any detailed information about this GTA?
I know Hahn-Manheim raced a few cars in the late 60's/early 70's but never heard of any of thier cars in Gruppe 2. Feel free to post any additional pics as these are the only ones in my file.

GTA HAEHN

As I remember was this GTA a 1600 chassis with alloy floor. The engine was a 1300cc Quattrovalvole. Bernd Fischer raced this car until the early 80's here in Germany . You should ask BB member Alleggerita. He knows more about this GTA.

The car is 613124, according my information the car Jochen Maas was starting his career
after Helmut Hähn gave him the chance.
Later in mid or late 70ies the car has been heavy modified to 660 kgs in the german silhouette race, driven by Bernd Fischer, he and Helmut Hähn doing a lot of development to the car, lots of titanium was included , 16 valv head, 11 inch wide wheels, titanium axles,
aluminium rollcage and more.
So far I know the car is now in USA

Haehn was a large Alfa dealer in Mannheim/Germany and one of the more prolific GTA shops in Germany from early on winning many Group 2 events particularly in the southwest of Germany. Tests of his race GTA's in Group 2 trim were featured in the automotive magazine "Auto, Motor und Sport" in the late 60's. As pointed out above, many well known drivers that include Jochen Mass, Gerhard Schueler, Bern Fischer and many others that were in one or another way involved with Haehn.

The early career of the car in the pictures above was in Group 2 with Gerhard Schueler. Schueler had a bad accident at Monza with a GTA-SA and later owned the discotheque Dorian Gray at Frankfurt airport, as well as a restaurant on top of the Frankfurt TV tower (Europa Turm).

The later carrer of the car was in Group 4/5 - GT and Special GT. At this point it was highly modified, mostly with aid from the expertise from its driver Bernd Fischer who continues to own a CNC machine shop that is involved in providing parts for Formula 1, DTM, aerospace and medical industry.

Fischer CNC-Technik GmbH

A detailed history of 613124 participation in various events is in the second edition of Alleggerita.

The last time I saw 613124 being used in anger was when it was driven by Helmut Haehn at a historic event at the Nurburgring sometime in the late 80's. A picture of it in that configuration with a 1300 4-valve engine is in the first edition of Alleggerita.

The picture shown in this thread must be fairly recent, as in that location in Haehn's shop there used to be a lot more cars, GTA's, GTA juniors and GTAm, at times being store one on top of another. Haehn sold the cars off over the years. To my knowledge 613124 was one of the last ones to go.

The MA-BF 555 license plate shown on the car was typical for Haehn where the second set of letters usually reflected the initials of the driver, eg BF for Bernd Fischer.

Thank you for the info guys!

Does Anyone have any info on those 11inch wide wheels if they are custom and what tires they were running?

Also those don't appear to be GTA Jr fenders correct? They seems to be a little wider, maybe custom?

The wheels if I remember correctly were 3-piece BBS racing wheels - pretty common at the time. Tires were slicks. Not sure what brand right now. Fenders were likely developed in-house by Haehn. Someone else may know more.

Bernd died about 20 years ago on the way back from Italy in his car. He was in Settimo Milanese to make a deal with Autodelta for the Production of Race Parts for them.

On my Gtam, when it had been modded to the max, it had 3 piece Speedlines and tires that could have fit an F2 of the time.
I still have them.

Thank for the info Alleggerita,
I would assume Hahn would have to be running 275-315 Tires to contain those 11 inch wheels right? I can't seem to find anything that relatively comes close to it in 13 inches.

Scuderia GTA

Hello,

here are two pics of the car from the mid 1980th (?).
That was a gathering of the Scuderia GTA that took place on the Nürburgring. On the grid standing before the 16V Hähn GTA is the GTA of Jürgen Zehra, that has been sold/offered recently.

Anybody know wich GTA the second one is thats standing left to the
16 V GTA?

Best regards

Christian
