The move to the United States depends on how Herbert performs in a test drive for the Pacwest team next week and whether he can find grand prix employment. "I have got to keep my options open," he said.
Herbert is still without a Formula One drive for next season, despite finishing fourth in the drivers' championship with Benetton-Renault. He is in competition with Mark Blundell for the second seat at Sauber-Ford alongside the German Heinz-Harald Frentzen.
Herbert, however, is keen to stay in Formula One and after wins last season at Silverstone and Monza knows he can compete with the best - provided he has the right machinery at his disposal.
"I don't want to be in grand prix racing just to make up the numbers," he said. "If, however, I can't drive with a competitive team, then I would certainly consider IndyCars."
Pacwest are searching for a leading driver to team up with another former Formula One driver, Brazil's Mauricio Gugelmin, in the IndyCar series which proved such a successful arena for Mansell. Herbert will test drive the team's Reynard-Ford at the Firebird circuit near Phoenix.Reuse content
