The "great days" of the automobile racing at the pointy end were in the 70's to the latest early 90's in IMSA and Japan, after that the world went HOMO so far as racing cars and categories goes, NASCAR formulas abound, its all about the show and fuck all about technological advancement and the most powerful racing cars. Contrived doctored air restricted boost limited NA only! or V8 only etc cookie cutter forms of racing divisions, and now ultimate insult is eco friendly bullshit sewn in = Elton John and George Michael in a Californian Public Toilet
In the world today there are cool sports, little pockets of turbo love where people apply all kinds of technology new and old and you see some sick cars!@ but sadly it is no longer main stream and no longer are the smartest minds and best people working in it ............. go figure that one out.
Sad but true you will see more exciting/technologically advanced cars at a Slovakian Hill Climb Meeting or a Norway rally cross event than you will see on a F1 BBC broad cast since the mid to late 1990's
