Marussia Virgin MVR02 – front wing without upper decks for Glock at Italy
Timo Glock chose to race at Monza a modified front wing which lacked the upper decks and provided less drag to boost top speed . On the contrary less experienced d’ Ambrosio raced the custom spec which gave him more confidence to challenge Parabolica . Glock also raced in Monza a rear wing without gurney tab for the same reason ( link ) but the top speed difference between the two Virgin racers was practically less than a half second favoring Glock . A larger gap would be expected though judging only by the different set ups , regarding downforce level , between Glock and d’Ambrosio cars . A possible explanation can be looked at engine usage (all drivers should use 8 engines in total for season ,otherwise a penalty is given) . Glock had No1 engine for a 4th race but d’Ambrosio No1 engine for a 3rd race .That would possibly justify a power loss due to fatigue for Glock’s engine treated with a lower downforce set up , but that’s just no more than a speculation without solid facts .
