“It’s tough, but we’ve been through all sorts of highs and lows as a team, and
we’re resilient enough,” said Whitmarsh.

“But the drivers know, and we know, we need to work on the car, make it
better, understand the tyres. Those are the things that are part of our job.

“So we’ll be pushing hard. I don’t think we need to build morale, everyone is
going to be pretty focused to try and achieve that.

“At this time I’m not seriously worried. Being worried doesn’t make the car go
quicker. Of course I’m disappointed, but there’s no magic.”

Whitmarsh has vowed a more visible upgrade package will be on the cars for the
German Grand Prix at Hockenheim on July 22, notably pertaining to the top
body at the rear.

However, he can offer no promises as to its performance, adding: “Anyone who
makes predictions this season is very rash.

“Everyone knows this team is strong and committed to winning, and the drivers
and team will be giving it their all. We’ll see what we can do when we get
to Germany.

“It’s a decent upgrade, although I’m sure no-one is going to stand still and
wait for us. You have to do a good job.

“We’ve been flat out as we always are. We’re trying to pull them (the
upgrades) through as quick as we can.”

For Whitmarsh, the Pirelli tyres continue to remain a mystery, as witnessed
with Hamilton on Sunday. He used two sets of the same hard compound, each
reacting differently.

“It is very tricky to go from being so strong in the first stint on one set of
prime (hard tyres), then about 15 minutes later you put them on again and
they feel different,” said Whitmarsh.

“They responded differently, yet we set the same pressures and temperatures,
so we have to understand them better because if you can get them working you
can be a second up, as we’ve seen.”
