Carlin dominated the opening day of the first collective test leading up to the start of this year's British Formula Three International Series campaign.

Starting his third year in the championship with the team Malaysian driver Jazeman Jaafar set the fastest time overall, lapping the Snetterton 300 circuit in 1:40.096 during the second of the day's two sessions.

The two hour, 30 minute afternoon session included all of the day's best times a drivers got up to pace in the first big test for the new Dallara F312 chassis that will make its debut this season.

Reaping the benefits of a private shakedown last week at Pemprey the Carlin drivers wrapped up the top five, with Jack Harvey starting his second season with team with the second fastest time, nearly three-tenths down on Jaafar. Third was the best of the team's new recruits – Pietro Fantin. Carlos Sainz Jr. was fourth fastest (his multiple World Rally champion father watching from the pitwall) with Harry Tincknell fifth.

Just over a second slower than Jaafar Formula Renault UK champion Alex Lynn was the best of the Fortec Motorsport drivers with teammates Pietro Fantin, Felix Serralles and Hannes Van Asseldonk all with a second on a day full of positives for the team.

“We are very pleased with our times,” said Fortec chief engineer Mick Kouros. “This is our first time out and things have gone well. This game is all about good preparation, and we came here well prepared.”

Hywel Lloyd was the best National Class runner, shaking down the hybrid chassis he will hand over before the season as he steps into a management role before the start of the season proper. Nick McBride and Spike Goddard followed for T-Sport.

Testing continues tomorrow on a second of running at Snetterton.
