Scuderia Toro Rosso launched its 2014 contender, coded STR9, in the Jerez pitlane on 27th January .
Key spots analysis on the new car follows
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.

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 .
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
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 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 .
