Following on .....:wave:
Motorsport usually reflects a Nation's style of road car.
Ferry makes the point very well, models that NASCAR purports to base the cars on are not commonly sold outside America.
It makes sense to see the BTCC running 2.0 litre 'hot hatches' because they are readily identifiable by the public, and more to the point, they are readily available from the local 'High Street Dealership'.
IIRC the ETCC run the same rules, so the SEAT raced in Spain or Portugal fits in to the British or French 'National' series as well.
During the 'Super Tourer' era, roughly 1990 to 2000, the National and International competition between serious 2.0 litre sedans produced some the best Tintop racing anywhere, certainly in the UK where (for example) almost every European and Japanese manufacturer were represented by 'Official' factory backed teams as well as well as numerous 'Privateers'.
Naturally, the 'Rulemakers' screwed that up, requiring stupid changes to regulations that made sense and produced great racing.
Instead of allowing Audi to run their 4WD cars and BMW to use the rear drive models (as sold in showrooms all over the World) they mandated FWD only ........ Audi built a car that the did not sell and BMW just withdrew.
The other side of the coin was the DTM, built around Alfa Romeo, Opel, Mercedes Benz, Audi and BMW, these cars were full on competition specials and during the earlier part of the decade looked fairly stock.
Audi withdrew IIRC around 1992 or '93, as their flat crank V8 was stretching the rules a little bit too far.
BMW followed soon after, as their 4 cylinder M3 was becoming uncompetitive, but Alfa, Mercedes and Opel came up with hairier and wilder cars which produced outstanding competition.
The present day DTM (have'nt followed it since 2005 or so) is a showcase for ultra hi-tech racing, the last time I looked Audi, Mercedes and Opel were running cars more complicated and advanced than F1.
And while the 'Super Touring' series were/are popular in Japan, the premier series consists of radically modified Toyotas, Nissans and Hondas, the 'All Japan GT Series'.
Once again, despite being GT cars, these are wild and hairy out and out race cars, regularly blowing such imports as Vipers, MacLarens, Lambos and Porsches into the weeds.
Bigtime!!!!
Not exactly 'sedan' racing but certainly 'tintops' .........
One other point, Japan does indeed have a modern and very well equipped oval, Motegi, owned by Honda and built for CART events.
I believe NASCAR ran an 'exhibition' race back when the much missed (by me) 'Ironhead' was doing his usual outstanding thing, but the Japanese were totally underwhelmed.
TBC.
