Toro Rosso STR9 Launch analysis

January 31, 2014 1 comment

   Scuderia Toro Rosso launched its 2014 contender, coded STR9, in the Jerez pitlane on 27th January .

Key spots analysis on the new car follows

 Toro_Rosso_ThreeQuarter_spots small

1.  STR9 retains a quite high and flat nose which ends to a finger-like  extension in a way to meet somehow the new 2014 nose height regulations. Furthermore the nose tip still is able to maintain an air inlet for cooling electronics housed inside the nose cone. Worries risen as finger extensions may potentially detach from the car, increasing the total amount of harmful flying debris on  front crash conditions .

2. No innovations or interesting spots on the front wing which bears large resemblance to last season .Consequently updated specs are likely to be seen soon

3.There is a small opening on the nose for aiding cockpit ventilation

4.Middle zones aero components (vertical sidepod panels and bargeboards) remain quite simple and conservative while the sidepod top surface vanes are now absent on launch version

5.Slightly enlarged sidepod inlets as cooling needs in 2014 are increased for all cars

6.Instead of sculpting  the area underneath the airbox inlet behind driver’s head, Toro Rosso put a large rectangular inlet there to help cooling efficiency. A similar tactic was followed by Mc laren during past. Additionally a small oval additional cooling opening also exists under the rectangular inlet.

7.New supplier of the power unit , changed from Ferrari to Renault

8.   Rear wing is supported on the floor via the lower section of the vertical endplates . That method of mounting increases the effectiveness hence more downforce, but also increases wing’s structural vibration. Above the central exhaust pipeline exit there is also a small arched multi  profiled plane to claw back some of the downforce lost caused from beam wing loss.

Toro Rosso STR8 – winter testing (pre season) tech summary


Toro Rosso STR8 SV Winter 1

Chassis :  STR8

Engine : Ferrari typo 056

 

 

     The STR8 has a slimmer rear end, better weight distribution which is shifted forward, redesigned rear suspension, interesting rear brake vanes and a full sized modesty panel . The sidepods of the new car show a deep undercut while the twin floor concept is abandoned as it was proved difficult to develop .Thus the radiators are now placed lower to the ground level allowing a more aggressively drop to the rear of the sidepod deck .

Winter testing updates :

  A modified diffuser was fitted on STR8 at last pre session test at Barcelona on March .

 

 

EVALUATION :

Aerodynamic performance :  offer a stable car but still questionable

Speed :.  Seems to be the last of the middle pack , faster only to Caterham and Marussia

Tyres management  :   above average

Reliability  :  well

 

Toro Rosso STR7 – Three rear wing specs so far !


      Red Bull genes are also found  within Toro Rosso’s DNA , not though in speed but mostly  in development rate . Till the Chinese GP three rear wing specs were raced/tested as shown in the images above. The Chinese spec was also  tested at Jerez on February and has a main flap with a bending upwards profile in its middle section to emphasize downforce production close to the endplates zone . Malaysian/Australian spec instead has the opposite philosophy on downforce production  featuring a bending downwards profile in the middle section . At Barcelona on March a mini plane was added on the beam wing  to increase downforce and  remains traditionally a good option for high downforce tracks like Monaco , Hungary and Singapore

Toro Rosso STR7 – New front wing for Melbourne


       Toro Rosso tested a new front wing at Barcelona on March  .The new wing has a shortened  slot in the main flap and also moved to the back to decrease the effective wing span in an attempt to make the wing less susceptible to sudden wing stalling (downforce loss) . Furthermore the main flap encounters  the endplates differently , the mini slot at the second flap close to the endplate is also new, while the endplate stand different on both rear end as well as to outer vertical elements .The new wing is being used by Toro Rosso since Melbourne .
