Hyundai to enter F1 in 2010

[Evan]

Their WRC program was a much better engineering investment than any winged carbon fiber tubbed 20krpm motored race program could ever be.

What are some of the technological innovations that have come out of WRC?

advanced awd systems, reliable parts, saftey structures, real world tire improvements, effective strut suspensions, engine durability
all direct improvements in a streetcar available in a short time frame to integrate with a production car. (if the manufacturer is paying attention, anyway)
Just about everything that has "come from f1" comes from it in concept only.
