1979 world champion Jody Scheckter, now a successful organic farmer, has $96 million, with Prodrive boss David Richards and David Coulthard coming next.
2008 title winner Lewis Hamilton's $80m fortune matches Scottish veteran Coulthard's, which is more than McLaren's other driver Jenson Button at $77m.
