[855] 07 May 2011 - Toro Rosso STR6 - integrated brake solution
 
This is a totally new solution introduced by Toro Rosso in Turkey, with the suspension upright and the fixing bell for the brake disc integrated as a single unit. Usually the bell is separate and then attached to the carbon disc to fix it to the upright (inset). This clever solution saves a little weight and is also stiffer.
[856] 07 May 2011 - Ferrari 150° Italia - new front wing
 
In Turkey, both Ferrari drivers have been using the new front wing tested only briefly by Fernando Alonso in Shangai. It's different from the previous one in all areas. Totally new is the endplate, with the lower part (1) cut as it was on last year's F10. The main profile is shaped differently in the area beside the endplate (2) and the endplate itself is now thinner and more curved towards the outside (3). The flap is divided into two sections which have different profiles (4 & 5), while the central pillars (6) now converge towards the rear of the nose. Finally there is a new adjustment mechanism (7) for the flap's incidence angle, similar to that used by most other teams.
[857] 08 May 2011 - Mercedes MGP W02 - slotted front wing
For the next round in Spain there will be a lot of changes on the Mercedes, with a new cooling system and exhausts. In Istanbul, however, they have again been taking advantage of this front wing, as used in China, with a slot in the main plane (highlighted in yellow). Together with a different aero and mechanical set-up, this has significantly improved the handling of the car.
[858] 08 May 2011 - Red Bull RB7 - exhaust layout
 
Red Bull brought to Istanbul a more sophisticated version of their exhaust, which better integrates with the car's side diffuser. But the new solution was destroyed when Sebastian Vettel slid off the track and into the barriers during Friday practice. So both Vettel and Mark Webber ran the team's more conventional solution (seen here) during qualifying and the race. It features a small horizontal flap (highlighted in yellow), originally introduced by Toro Rosso at the launch of their car (and subsequently tested by Ferrari on Friday), designed to improve cohesion between the air flowing from the exhausts (red arrows) and from the rear diffuser (blue arrows).
[859] 08 May 2011 - Renault R31 - revised front wing
Renault came to Istanbul with a front-wing solution similar to Ferrari's in that it has much longer central pillars, with the cameras mounted on the inside. The rest of the wing is largely similar to the team's previous solution.
