Vitantonio Liuzzi clocked the seventh fastest time as Force India's 2010 challenger VJM03 made a smooth debut with more than 300 KMs of trouble-free run and no reliability issue on day one of their four-day testing at the Circuit de Jerez here.

The wet condition notwithstanding, Liuzzi completed 71 laps to cover 314 km with focus on system familiarisation in the morning and then balance runs in the afternoon.
