Timo Glock has said that the Toyota will be able to strike back in the remaining four races and score points after the Cologne-based outfit came away from the Italian Grand Prix empty-handed.
Glock and team-mate Jarno Trulli both qualified quite strongly for the 14th round in this year's championship. However in the race itself an extra stop to switch to standard wet tyres proved extremely costly, with Timo finishing eleventh and Jarno coming home 13th.
"Overall it was just quite a difficult day for us," Glock reflected. "I made a good start but I lost a couple of seconds soon afterwards when I spun as I tried to overtake [Fernando] Alonso.
"Early on it was very hard to see through all the spray when the track was at its wettest. It was hard to attack but I still managed to pull off some moves.
"Then the extra stop cost us the chance to go for points. It's obviously a shame to finish where we did but we were unlucky and our pace shows we can score again in the coming races."
Toyota team boss Tadashi Yamashina meanwhile also blamed the weather for their inability to score - something that has allowed Renault to draw level in the fight for fourth in the constructors' championship, both teams having now notched up 41 points.
"Everybody did their best today but the weather did not help us. We qualified well and we went for a one-stop strategy. Unfortunately we were in exactly the wrong window because the teams who did two stops and the teams on a longer one-stop strategy could both time their stops better.
"We were caught in the middle, just like Nico Rosberg's Williams. Still, we were very quick in the first stint with the extreme wet tyres, the drivers did well and the car's performance was good. But there was not much more we could do today," Yamashina summed-up.
