INDIANAPOLIS—Helio Castroneves is being replaced on Team Penske by Australian driver Will Power—at least until the two-time Indianapolis 500 winner’s tax evasion trail is resolved. Castroneves, who has pleaded innocent to charges of conspiracy and tax evasion involving about $5.5 million in income stashed in offshore accounts, is scheduled to go to trial in Miami on March 2, just over a month before the IndyCar season begins.
