Who is Jochen Mass?

May be...

I do not know why do you ask this in the NASCAR Section?

Mass was a German F1 driver during the 70s and 80s. He finished on the podium 8 times, and won his only race at the 1975 Spanish Grand Prix. He went into sports car with good sucess, including teaming up with Bobby Rahal. http://en.wikipedia.org/wiki/Jochen_Mass

He wasn't a NASCAR driver, for sure.
