Virgin VR01 – Floor side fences


 

           The vertical fence ( yellow arrow ) prevents any interaction between the air flow coming from the inner bargeboard-body zone with the one coming from under floor . Such an interaction would create unwanted turbulence  and an increase in under floor air pressure causing the car body to produce less downforce .

Virgin VR01 – Periscope exhausts


           VR01 has periscope style exhausts . The 2010 trend about exhaust configuration is the EBD (exhaust blown diffuser) design and thus  periscope exhausts are considered to be old fashioned now . Low team budget , lack of experience and uncertain future about 2011 due to financial issues were the factors that prevented the team from launching and testing analogous EBD system to its VR01 even though Virgin showed remarkable development rate for a rookie team during the season .

Virgin VR01 – Front suspension


 

        VR01 features a pushrod zero keel front suspension  configuration  with the steering axis made of carbon fibres  to be  placed a bit lower than the upper wishbone . The wishbones are also made of carbon and have titanium flexure joints while the wheel upright is made of aluminium alloy .

Virgin VR01 – B spec car since Spain


       Virgin asked permission from FIA to construct a B version of its VR01 because the car carried a smaller fuel tank than needed to complete a full race distance in some occasions . The problem was caused by miscalculating Cosworth engine fuel needs in high fuel demanding tracks .

        Despite the fact that chassis are homologate FIA gave the green light as some changes are possible for reliability issues . A single new car was available at Spain and Monaco only for Timo Glock while Di Grassi had to race the old car . However both Virgin drivers had the new car since Turkey .

    The B version had a longer wheelbase to accommodate a larger fuel tank and an updated engine cover and rear zone .

Virgin VR01 – Rear wing , Bahraini spec


 

        The rear wing is also quite simple like the front one  . In details the main flap has a small slit in the middle part to prevent wing’s stalling in high speed and high attack angle while the endplates feature four gills to reduce drag .

Virgin VR01 – Front wing , Bahraini spec


 

         VR01 was the first F1 car ever to be entirely designed by CFD program with the team  lacking totally wind tunnel data  . So Virgin preferred to start the season at Bahrain with a simple double profiled  front wing with slotted endplates instead of using a much more complicated one . The reason was that a simpler wing would gave simpler track data to evaluate and compare car overall aero performance with theoretical data extracted from CFD .
