Tuesday 26 May at 15:59 : May 26 (GMM) Red Bull is planning to stick with its new 'double diffuser' for the Turkish grand prix and beyond

The concept's debut on the RB5 at Monaco last weekend was later than many of the team's rivals, because it required a substantial reworking of the unique characteristics at the rear of the car

And after beginning to look at match at recent races for the dominant Brawns without the diffuser, Sebastian Vettel and Mark Webber were slightly off the boil on the Principality's streets

Moreover, Vettel dropped dramatically off the pace with ruined soft tyres at the beginning of Sunday's race, leading to his crash and retirement at Ste Devote

Team boss Christian Horner, however, said Red Bull had always predicted that Monaco would not suit the high-speed aerodynamic characteristics of the Adrian Newey-penned car

And he said it is wrong to blame the new diffuser

"We can see that it has put aero performance on the car," he insisted

"It will be interesting when we go to Istanbul and Silverstone. Theoretically they are tracks that should come to the characteristics of our car," added Horner
