These comparisons only use the top speeds recorded through the regular speed
trap during the Saturday qualifying sessions. This means that, at most events,
there are comparisons that are fairly meaningless because of some problem that
affected one or more drivers during one particular session.

The first table compares the 2006 team/driver combination with the equivalent
2007 team/driver - the same driver if possible, otherwise the 2006 driver is
compared to his 2007 replacement. This is intended as a team comparison, but
the first table is also of interest - but should be read with care.

Note: Coulthard's 2006 speed was not representative as he failed to do a single
flying lap in Q1.


The second table compares the best speed achieved by each team (IE both drivers),
and as such is a better measure of the year-on-year change.
