Technical director James Key says he feels the Istanbul circuit will be better suited to Sauber as the team looks to pick up its first points of the F1 season in Turkey.

A double retirement in Monaco for Pedro de la Rosa and Kamui Kobayashi means the team remains the only established outfit still to trouble the scorers this season but with a series of small upgrades due to be introduced to the C29 next weekend, Key said he was hopeful of a stronger showing.

"It's a more normal circuit compared to where we have just come from, and I think it should suit our car better," he said. "Because of this we are looking to return to the form we showed in Barcelona, and carry all our set-up directions from there to Istanbul.

"We will use the F-Duct system again in Turkey, and we will also have some small aerodynamic updates on the car which should help us to be competitive."

De la Rosa in particular has endured a trying start to the year and has picked up just one finish in sixth races, with the Spaniard saying he was desperate to see the chequered flag.

"I think Istanbul Park is a track where we should be able to regain the competiveness we showed in Barcelona, therefore I'm very much looking forward to the Turkish Grand Prix," he said. "I like the circuit. The last time I raced there was in 2006 and I finished fifth. Certainly the most challenging corner is turn eight - it is the longest high speed corner of the championship.

"With G-Forces of approximately four g for a period of six seconds on each lap this turn is pretty demanding for the tyres and the neck. Again, I desperately want to finish a race."
