Kiwi driver Earl Bamber's cameo in Supercars next year is the latest example of elite level racing drivers swapping from one major category to another within a season.
That used to be the norm in the 1960s and 70s but as the major championships became big business specialization was forced onto drivers.
But over the last 12 months we have seen Kiwi Brendon Hartley successfully contest Formula 1 and the World Endurance Championship simultaneously. McLaren driver Fernando Alonso took a hiatus from Formula 1 earlier in the year to have a crack at the Indianapolis 500 while another Kiwi Richie Stanaway successfully made the switch from single seaters and sports cars to Supercars.
"I think it just shows that at the moment in motor racing people are looking around at different disciplines to take different drivers from," Bamber told The Herald having returned to New Zealand for Christmas after a break-through season in which he won both the World Endurance Championship and the Le Mans 24 Hour race with the factory Porsche team.
"Brendon is one example from sports cars to Formula 1 but then Fernando went from Formula 1 to Indycars and did a mega job. Richie went from sports cars to Supercars and did a terrific job too.
