Norbert Vettel, 53, is a carpenter by trade but in the past contested hill-climb events and got his son - now the reigning double world champion and new 2012 title leader - into a go-kart at the age of 3 and a half.
Bild said he will race in the Volkswagen Scirocco R-Cup race at Hockenheim this weekend.
"It's my first start after an 18 year break!" Vettel snr is quoted as saying.
"I used to do hill races, but there were no opponents on the track, just the clock. So I just want to stay humble and not finish last."
