Vauxhall's Astra Coupe engines will be supplied by French company "Sodemo", and
not by "Spiess", who have worked on the Vectra engine in recent years. The move follows concerns that
Spiess would be too involved with Opel's DTM project to devote the time needed to the BTCC challenger. Sodemo
have recently worked with both Renault and Ford in the BTCC.
