The Bugatti Veyron launched in 2005 with 1K horsepower and cost > $1M. As of last year, you could get a Dodge Challenger with 1K horsepower for <$100K. Those prices are unadjusted for inflation, so the price difference is even greater than 10x.

While it is not a guarantee, the innovations in today's supercars do tend to become much more common with time.

I think you're drawing a lot of conclusions from that correlation.

what innovations did the Veyron introduce that the Challenger used?

And what a car it is!
