Toyota enjoyed a solid start to the Belgian Grand Prix weekend at Spa after both Jarno Trulli and Timo Glock were able to run near the front during Friday practice.

Trulli was one of the few drivers to post a quick time before rain arrived in the first free practice session and set the quickest time as a result.

While he was unable to retain his position at the top of the times in a dry second session, Trulli still ended the day with the seventh quickest time overall and said he was confident of a strong weekend for the Cologne-based squad.

"It was a good Friday for us," the Italian said. "Obviously there is still work to do to get the most out of the car and I need to find a bit more grip at the rear end but all in all I am very happy with the results today. I have a good feeling from the car so I hope it will be a competitive weekend for us.

"The track was wet this morning which meant we couldn't do all of the tests we had planned but we did some laps to better understand the car in those conditions. In the afternoon, when it was dry, the track just got quicker and quicker. I was working mainly on race pace today, getting the car set-up in race trim so we have a good balance for Sunday, and it seems to be reacting well."

Team-mate Glock was one of the drivers who failed to set a representative time during the first session after only venturing onto the track after the rain had arrived, leaving him well off the pace in 18th as a result.

However, in the afternoon, the German ended up just 0.016secs behind pace setter Lewis Hamilton in a strong second overall.

"It's hard to draw any conclusions from the wet session this morning but I am pleased to be second in the afternoon; that is very encouraging," Glock said afterwards. "The car felt pretty good and the lap times show that. Still, there are a couple of areas to improve so we will work on those before qualifying and try to find the perfect aerodynamic balance. I am happy with how things went today and I'm interested to see where we are tomorrow."
