The New Zealand motoracing driver Brendon Hartley was off the pace on the first day of Formula One testing at Jerez in Spain.
Hartley was back in a Toro Rosso car for the 3-day session especially for young drivers, but was the slowest of the dozen drivers in action today.
Hartley, who has been racing in the European Formula 3 Championship for sister team Red Bull, remains in contention as a backup driver, but there is a lot of talk about his Italian team-mate Mirko Bortolotti, who will test in the car tonight.
Formula One has limited test sessions in an attempt to restrict spending.
Andy Soucek, who won the Formula 2 Championship this year, was fastest today in a Williams.
