Doornbos has ended his contract with Zecchi as he wants to race in the American ChampCar series this season. Doornbos was in Houston this week for a two-day test with ChampCar team Minardi Team USA.
The 25-year-old showed his form as he set the fourth fastest time on the clocks in his first day of testing in Houston.
