I for one always thought all the manufactures in the BTCC had their own racing divisions making their own engines for thier own car. How wrong was I until I read this 2015 BTCC Honda Civic Type-R driven | Autocar Honda make their own engines for the BTCC car and the rest of the grid is supplied by Swindon Engine http://www.swindon-engines.com/images/Document/TOCA2021.pdf Swindon Powertrain | Manufacturing | Testing | Design Swindon Powertrain | Manufacturing | Testing | Design see all the news clips which suggest the entire grid is supplied this unbranded engine. Swindon’s engines will be found under the bonnet of a total of fourteen cars in this year’s BTCC. Three MGs from Triple Eight, two Volkswagen and two Vauxhalls from team BMR, two Toyotas from Speedworks and one from Lea Wood Racing, one Mercedes from Ciceley, two Audis from RAR and one from Rotek will all be powered by engines designed, developed and manufactured by Swindon. In addition, Swindon provides dedicated Support Engineers at each race week-end, working together with the teams to help get the most performance out onto the track.
