How do you know when you are a team's test driver? When you have to turn up at Silverstone in February. 

The  "Home  of  British  Motor  Racing"  lived  up  to  its  reputation  for  having  a  unique microclimate, with freezing cold temperatures as Robert Doornbos continued development work on the RB2.

But every cloud has a silver lining and partly because of the cold and partly because ofrevisions  to  the  current  car,  the  Dutchman  was  able  to  put  together  some  long  runs, something  that  had  not  been  possible  to  date,  because  of  cooling  problems.  Yesterday's testing  centred  on  these  modifications  as  well  as  some  other  aerodynamic  elements.

"Apart from that, we continued work with an on-going brake development programme andsome  general  set-up  work,  as  Robert  has  not  yet  had  much  time  in  the  car," said Chief Test Engineer, Ian Morgan. "We also put in some useful pit-stop practice at the end of the day."

Christian Klien takes over in the cockpit today for the final day of this test.
