The new RB10 was launched on 28/01/2014 in Jerez Track and it is product of hard work out of clean sheet . Key spots analysis follows
1.At front the nose structure differs somehow from the finger extension design, having an elegant thin keel extension, very similar to the one seen a decade ago when cars still had single keel chassis to hold the front suspension’s lower wishbones . The overall nose stands closer to the ground , flat on top but bulgy underneath to stimulate the front wing’s efficiency as front wing holds to the nose via smaller pillars .
2. Front wing remains highly complicated, and transforms from a four-element wing to a six-element close to the endplates . Under flaps vanes, hard to observe, look very sophisticated either.
3. The S Duct inside the nose cone, just in front of the bulkhead, remains on RB10, but of course adjusted to altered aero demands of 2014 . It helps to discourage flow detachment that takes place under the nose . Possibly the same system is capable of providing additional cooling solutions for nose housed electronics or even for cockpit ventilation.
4. As expected sidepod openings took special treatment so as to both provide additional cooling in 2014 and sustain an optimum aerodynamic silhouette. Sidepod tunnels look still very tight, highly sculpted at bottoms with a completely different end which closes smoothly to the car’s centerline having now lost the exhaust Coanda ramps and the tunnels underneath them .
5.Inside the RB10 a completely new packaging of ERS batteries, radiators, electronics and engine parts took place under the skin compared to previous RB9 .
6. An extra rectangular cooling inlet absent on RB9 and smaller to the analogous seen on Toro Rosso STR9, exists under the airbox main opening. Furthermore that zone continues to be very sculpted for keeping drag as low as possible.
7. Rear wing is supported via a single support onto the car’s body, just above the engine funnel. For easier wing assembling that support is attached on a base extension a few centimeters above the engine cover . It is uncertain if DRS components are now housed inside that pillar, but that would be the logical step as beam wing, useful for connecting the system via the endplates to the car, is now absent. Furthermore such a configuration is simpler and less vulnerable to malefactions.
8. The single exhaust terminal pipeline is housed inside the oval shaped engine cover’s funnel, with the latest to be a common feature on all recent Red Bull cars .

Chassis : RB9
Engine : Renault RS27 – 2013
RB9 is a refined version of the previous RB8 (2012 car) , with a “dwarf” vanity panel to cover the stepped nose, a more rigid front wing to meet the stricter FIA regulations regarding flexibility , retained ramp-exit exhausts, tunnelled sidepods and with a passive drag reduction system ,separated from DRS to cut further drag favouring top speed.
The S duct feature which is pioneered by Sauber in 2012 is present on RB9 . It helps to smoothen the negative effects of the boundary layer under the nose . The boundary layer is a slowed stream of air flowing close to a surface due to friction . The small vanity panel on the stepped nose section , alongside with the introduction of the S duct forced Red Bull to abandon the nose letterbox design which aided cooling .
Winter testing updates :
At Barcelona test on February Red Bull tried a low downforce set up rejecting at the same time the beam winglet, also placed extended heat shields on the engine cover around the exhaust zone and featured minor diffuser revisions . A new front wing, revised larger vanity panel and rear wing endplates with horizontal gills instead of curves made debut at second Barcelona test . It was also interesting to see Red Bull to reject the new diffuser and revert back to the old spec .
Aerodynamic performance : very efficient as all Adrian Newey’s creations, provides good aero balance and enough grip .
Speed : very fast at both low and heavy fuel loads but shows very low top speed at straights . The ban of DRS free use at will during qualifying could potentially transform the low top speed issue into a real handicap for the team .
Tyres management : average for all three compounds, soft, medium and hard .
Reliability : pretty good
ramp-exit exhausts, FIA refused permission to Renault to change engine mapping in 2013 that would potentially enhance the positive effect of the ramp exhausts
All teams,including Red Bull, at Sepang pay a greater attention to the cooling efficiency of the car. Thus RB8 raced with gilled larger hot air outlets at both cockpit sides , which replaced the Australian simpler holes . The slots on sidepod tops ( pointed with green arrow) remained for Malaysia . That slots were present since the launch of the new RB8 but they were rejected during pre-season testing before coming back again at Melbourne .

At Malaysia Red Bull relocated the nose cameras to a lower position inside the wing pillars .The new position , first seen in Red Bull in 2010 , offers a small increase in downforce production , while former position a better airflow management around the nose cone .
New sidepod panels have also been placed on the car before Melbourne. Old panel had a wing-alike joint that connected the middle of the panel to the chassis .The new one has a top extension that bents vertically inwards to meet the sidepod roof, resembling more to a ‘biting jaws’ style connection , which is less draggy, leaving more room for air to pass through the panel and the car body guaranteeing a richer flow to the rear .
Red Bull easily dominated in 2011 but will the new car be able to repeat a clear sweep over 2012 titles ? People in Red Bull insist that 2012 championship will be tighter than 2011 but it is obvious that solid optimism glows all over their faces . That optimism is based on the hard work they have done to evolve the previous RB7 car into the new RB8 and overcome downforce loss due to EBD (Exhaust blown diffuser ) ban . Actually Red Bull says that RB8 is the fourth evolution 0f RB5 -2009 car .
Cameras are attached at nose tip creating a distinctive T-Nose shape resembling to hammerhead shark , a familiar nose concept not only for Red Bull but for Williams as well .
The nose vanes are clearly an update of RB7 late season ones inspired from Renault R30 -2010 . Their use is to channel air under the chassis . The updated vanes sports a deep cut at their bottoms and because of that have an additional aerodynamic role which is to create turbulence across the vertical axis to reduce drag when turbulent air heats on car body
The front wing is derived from late 2011 season and without doubt is a jewel on RB8 . It will for sure follow an aggressive development rate . For instance RB7 front wing had at list 15th different revisions over 2011 season , some of which were only tested .
CHASSIS – NOSE DUCT
The RB7 had a highly raised chassis at the front to allow large quantity of air to flow underneath , a concept retained for RB8 . New 2012 regulations dictated all teams to develop strange stepped noses for their 2012 contenders including Red Bull . The only team so far ( HRT and Marussia new cars are not launched yet) to develop a lower banana shaped nose is Mc Laren . The striking difference between RB8 nose and other cars is that Red Bull exploited the stepped area placing there an elegant duct . There are rumors over the duct functioning with the major of which to be :
– to feed a possible cockpit ventilation with fresh air to cool down the driver (most likely) . Many teams often put a duct on chassis top just in front of the cockpit for this cause .
– to direct air inside the chassis to cool KERS components which are located under and behind the driver’s seat . A more efficient way to cool KERS , due to structural reasons , would be through the duct located under the chassis already seen on RB7 .
– to cool electronics located inside the nose
– to direct air inside the nose cone towards the front wing , to stall it favoring higher top speed in an analogous way Mercedes did last season . This actually is the most unlikely of all , because mechanics had to change air direction to the opposite, something that would create unwanted drag that would neutralize any benefits from front wing stalling.
– the duct is a dead end and creates a high pressure zone (air dam) in front of the opening which helps to bent airflow over the stepped area more smoothly over the nose with less friction . However the air canal created on chassis top due to raised sides do not seem to work nice with the air dam hypothesis .
The external width of the survival cell must be no less than 6 cm per side wider than the cockpit opening when measured normal to the inside of the cockpit aperture. These minimum dimensions must be maintained over a height of at least 350mm. The chassis is raised on top at both sides and thus a channel is created ( U –raised chassis )
COCKPIT VENTILATION – THE MOST POSSIBLE OPTION
The chassis side wall thickness is not able to contain a hole ,because such an option would create stiffness issues and probably possible cracking in a crash side test . Most likely the air route is attached on the inside surface of the chassis wall right next to driver’s legs and crosses the survival cell to reach the cockpit zone . Adrian Newey also confirmed that the duct is for driver cooling .
A possible route for cockpit cooling
Floor exhausts allowed RB7 last season to race with its rear end higher from the ground level and its front closer at the same degree to maximize front wing efficiency . 2012 Periscope exhausts according to Adrian Newey ( technical director of Red Bull) will force the RB8 to race with a more neutral ride height leading not only to downforce loss at the rear of the car but also to front aerodynamic grip loss .
SIDEPODS – REAR ZONE
The sidepods remain very compact following the pattern of RB7 and the gearbox zone I even tighter packaged . Hot air exits are similar to RB7 , double outlets at gearbox sides and a funnel at the end of the engine cover . The rear wing at its launch version looks very similar to last season .
