Wow, that's awesome. I'd read somewhere about the S60 spec series in Sweden, but this is much more bigtime. Volvo needs to be in more motorsport, and this series could maybe be that. I remember the good ole days of BTCC when Volvo ran the stationwagons. How cool was that? I think Rydell drove them too.
Anyway, I always thought the Touring Car setup would do well here in the US, though the defunct NATCC never quite worked out. The format though rocks, because anyone who builds a sedan could technically run an entrant.
Remember Audi getting banned with AWD. In the beginning, the BTCC was open to any drive style (bimmers were rwd) and 4, 5 or 6 cyl as long as it was 2.0 liters. That flexibility rocked, and I wonder if Volvo would run the new Haldex system (or a variant) if AWD were allowed?
Volvo should join F1 or go to LeMans if they don't do this.
