Ferrari F138 – Rear wing , Melbourne spec

D spec – second Barcelona test and Australia

D spec – second Barcelona test on March

       At second Barcelona test one more new wing spec appeared which at a first glimpse looks alike with the previous version but any similarity collapses with a closer look in details . The upper part of the wing is completely new , it has new endplates with a less intense cut on top and shortened gills which allowed the construction of a longer second flap, all changes to improve downforce production . Finally the new spec gives more freedom for mechanics to adjust the attack angle of the flaps as it sports additional adjustment points on the outer section of the endplates for that cause .

      The D spec came by with a new higher downforce front wing to keep the aerodynamic balance of the car unaffected .

At Melbourne and Sepang Ferrari discarded the beam winglet favoring greater top speed  but kept the rest wing characteristics unchanged .

Ferrari F138 – Rear wing , Jerez test updates

B and C specs – Jerez test on February

B and C specs – Jerez test on February

     A revised wing ( B spec) made its debut at the first pre season test at Jerez having an additional single profiled winglet ( also called beam winglet or monkey seat), which was mounted on the allowed centre zone of the beam wing to increase the overall efficiency of the wing .

     Later during the Jerez test Ferrari attached on the trailing tip of the second flap (highlighted in yellow , C spec – inset) a large gurney tab . Gurney tab makes the wing act like having a larger chord than it actually does and moreover allow steeper flap angles preventing stalling, hence produce more downforce with a small drag penalty.

Ferrari F138 – rear wing, launch version

   F138 since launch was gifted with an innovative rear wing, which sports vaned endplates. They, accompanied by multiple blade shaped elements hanging from the endplate bottom, help to extract air from inside the endplate’s zone to the outside hence improve the efficiency of both the diffuser and the wing itself . The DRS activation mechanism is also much slimmer than last year .

Ferrari F138 – winter testing (pre season) tech summary

Ferrari F138 SV Jerez 1

Chassis :  F138

Engine :Ferrari typo 056


    Ferrari eager to claim the champions from the start of the season and F138 seems capable of playing that role . On the contrary F2012 faced serious performance issues from its first day on track . The most eye catching features on the new F138 is the large chassis duct under the nose to feed chassis electronics with cooling air and  improve the undernose aerodynamic efficiency at the same time , oversized front wing pillars and vaned rear wing endplates . Detailed changes to the design of the front and rear brake ducts  also occurred .  Finally the driveshaft is also housed inside the lower wishbone of the rear suspension system for drag reduction like Mc Laren, Mercedes  and Red Bull .

Winter testing updates :

     Ferrari practiced every possible aid to collect and evaluate track data , such as pitot rakes , fluorescent paint and sensors housed around the car . All the previous mentioned come and gone according to testing needs . However a heat sensor is planted permanently  inside the support of  sidepod panel to monitor front tyre temperature.

    Speaking about the changes that took place from launch the major ones are the following

– at Jerez Ferrari tried cockpit gills to aid cooling and a new wider chassis duct to aid cockpit ventilation

– at Barcelona test on February the exhausts pipeline gained an additional support to decrease vibration and a revised engine cover to improve cooling further.

– at last pre season test at Barcelona numerous updates added on the car including  a new front wing , longitudinally vanes on nose cone sides, revised exhaust outlets , new diffuser and rear wing .




Aerodynamic performance :  seems to have overcome last season rear end stability issues

Speed :. Very fast on low fuel load but average on long runs under heavy fuel load

Tyres management  :   quite consistent but suffers  degradation leading to significant and gradually  lap time loss . The problem seems to be worse on medium and hard compound

Reliability  :  overheating issues came up at Jerez but seems to be gone now. Massa also suffered a suspension upright failure

Ferrari F2012 – Middle zone updates at China

Launch spec

Launch spec


       The F2012 had already received  several front wing updates before China , thus meaning that  some parts of the car should be re-examined to cope better with new aerodynamic elements .

 China- racing spec ,  old bargeboards and turning vanes are shown in the inset , the yellow arrows present the exact spots were changes took place .

China- racing spec , old bargeboards and turning vanes are shown in the inset , the yellow arrows present the exact spots were changes took place .

The first step to this direction was taken at China where new turning vanes and bargeboards replaced the old ones . The new turning vanes had a reshaped sharper end with  an additional vertical fin, while the bargeboard gained a winglet close to the turning vanes. Furthermore the large triangular chassis vane was replaced by more elegant double winglets spotted just behind the mirror, aiming to reduce further the amount of lift created by the sidepods .

 China – tested only ,the new double chassis winglets were tested even without the rest updates

The new chassis winglets were even tested with the old turning vanes-bargeboards,  giving the impression that Ferrari was sure on their positive effect but had doubts on the rest updates .




Ferrari F2012 – color change on nose pillars since Mugello

        A minor livery change occurred at Mugello. Particularly the nose pillars adopted since then a semi black color , bringing into memory the old  black-red livery that Ferrari used to race many years ago  .

      Speaking for Ferrari’s livery ,it changed from a red-black livery in 1990’s to a red-white in 2000’s, then into a full red one (2007) to return back to red-white recently. It gives me a clue to expect  next year black colored front and rear wing flaps .
