Cape Town - Brendon Hartley could have an advantage over his team-mate
Pierre Gasly in Mexico this weekend with the New Zealander set to run the
team's only upgraded package.
This weekend, looking to add to the four points he has
scored so far in the championship, Hartley will have a new front wing and floor
fitted to his STR13.
His team-mate Gasly ran the updates during the practice
sessions at the United States GP, however, the rain meant the team wasn't able
to evaluate the new parts and therefore reverted to the older specifications
ahead of qualifying.
Hartley will use the updates in practice before a decision
is made on whether to continue using them for qualifying and the race.
"Definitely there's a lot for the engineers to look at,
data-wise," he said.
"I think Pierre wasn't happy with the balance in FP3
when he ran the aero so that's partly why they removed it.
"So it's going to be interesting to see how it
performs, if we can get any more performance out of it.
"In terms of the rest of the weekend I think there's
not a clear plan yet, it really depends how tomorrow goes."
With three races remaining, Toro Rosso are eighth in the
championship on 32 points, four ahead of Sauber.
