Hi, anyone have photos of the Erwin Doctor Calibra 4x4 during the 93 season?

Hi. Photos of that car are rare. I remember a fantastic video onbord in the snow with Erwin Doctor's codriver Theo Badenberg all the time shouting "mach doch hachte" "Duitch free go more careful, very panicy...)

I think the first picture might be Rallye Catalunya 1993, as far as I remember of my head right now the only WRC start for Doctor in that car. Doctor always drive A17 MSD (private plate, original Luton plate K91 ATM) MSD only built two cars, the other being A15 MSD (A16 MSD was on an Astra GSI 16v, and the car in which Dave Metcalfe lost his life was Harry Hockly built for a customer in Germany). Jimmy McRae did a couple of rallies in a Calibra 4x4 Turbo too which A15 MSD after Blomqvist never drove this car again.

Stig Blomqvist drove A15 MSD in Sweden 1993:

That was the first rally car in WRC with active differentials, and the story of retirement was well funny too. It still remained the only official (as in works backed) start for this model. See this story:


"

Would you ever have tipped the Opel Calibra to be the first rally car with active differentials? Yes indeed! For once Opel seemed to be ahead of the times in rallying, but unfortunately the project only led to embarrassment.
The Opel Calibra Turbo 4x4 is a little known road car. But Opel experimented a lot with it. On paper the car had all the right ingredients for a group A rally car: It was a coupé of decent size, it had a 1998cc engine, a turbo and 4x4. But group A rallying proved the Calibra Turbo 4x4 road car having a design error similar to the Nissan Sunny GTI-R case. On the Calibra, it was not the intercooler to be the offending part. Opel, a company with little turbo experience, wanted to find a way to reduce the turbo lag. Their thought: 'The nearer the turbo is to the exhaust manifold, the lesser is the turbo lag'. So the Opel engineers did locate the turbo right inside the manifold, rather than behind! The lesson they learned: They were correct about the lag, but 'The nearer the turbo is to the exhaust manifold, the hotter it will get'. Indeed, the turbo developed massive termic problems and that affected engine performance and reliability.
All this lead to a funny incident on the car's only event as a works car. An incident that shows amazing expertise of a legend driver: British experts MSD, later known for an unhappy Hyundai partnership, were ordered to turn the base Calibra Turbo 4x4 into a group A rally car. The car debuted on the Rally Sweden 1993 with Stig Blomqvist as a driver. Stage times were around 10th place, not overwhelming, but acceptable for a brand new car. The lack of performance was soon attributed to termic problems affecting power. For 20 stages the car ran reliably. After SS20 Stig said at service: "There is a problem with the head gasket". The mechanics checked everything, but couldn't find any sign to confirm the problem. When asked how he knew, Stig replied: "I smell it". At that point the mechanics declared Stig insane, shut the bonnet and sent him out again. On SS21 Stig and the Calibra retired with a blown head gasket!
After that show, Opel was disappointed and the car was never seen again as a works car. MSD built two cars: A15 MSD & A17 MSD. A15 MSD was after the Blomqvist one off drive used by Jimmy McRae in some British events and only confirmed its problems. A17 MSD actually had a busy life with Netherland's Erwin Doctor and indeed won the Zuiderzee Rally 1993. But that success stayed an exception.Don't confuse the Calibra Turbo 4x4 with the many Calibra entries we have for Bruno Thiry. These entries were by GM Belgium who, like MSD, were hugely active at the time (See the Opel Astra F story). But the Opel Belgium car was an F2 Calibra, no turbo, no 4x4, the car was technically identical to the Astra F. Here however the Astra had an advantage for being smaller and lighter than the Calibra."

Well, that's about all I know of this project, hope it helped.

You're right, Chris... the first picture comes from the '93 Catalunya.


Carles.
