Programme A difficult final day for Jenson and the team.

The engineers were able to carry out some significant set-up work during the

morning’s early laps. However, the team’s attempts to understand the

behavior of its Melbourne-spec front wing – which arrived this morning – were

curtailed by a late-morning red-flag.

After lunch, Jenson only managed a few laps before suffering a high-mileage

internal combustion engine failure, which kept his car in the garage for much

of the afternoon while the unit was replaced.

At the end of the day, any further attempts to run were hit by an as-yet

undiagnosed control electronics problem – the result of which is that the team

had no driver feedback upon which to evaluate the new front wing. The

engineers will be able to evaluate its strengths using the limited run-data we

accumulated during the day.

Jenson was able to run a final lap under the Bahrain International Circuit’s

spotlights – the session was extended by 30 minutes to allow the new system

to be tested ahead of next month’s night race.
