I think that so long as there are cars around for teams to race, we don’t need works teams. Sure, having big brands like Honda and Ford is nice, but it’s not essential in any way.
I did find it quite amusing that Chevrolet were using the BTCC to help the WTCC programme, despite comparisons being about useless because the BTCC uses Dunlop tyres. Unlike Honda and Ford, I never thought that Chevrolet were in it for the long run, and that they would pull out as soon as they weren’t winning. And with most of the grid using NGTC cars, they would have been midfield at best. At least Plato’s still around, that’ll keep the colour in BTCC this year.
