Toro Rosso plans to evaluate its biggest in-season upgrade of the year at this week’s Formula 1 test at the Red Bull Ring, following last weekend’s Austrian Grand Prix.
The Italian team brought a lot of new parts to Austria for the race, marking its biggest list of changes since the package it brought for the final pre-season test in Spain.
While Toro Rosso was already satisfied over the weekend that the updates were a step forward from the car it raced in Canada earlier this month, it believes it will get a definitive verdict when it tests both specifications this week.
“Testing is always valuable because there is always stuff you want to do and things you want to learn, so we have an absolutely full test list for two days,” said Toro Rosso’s technical director James Key. “The biggest change [to the car] is this race, believe it or not, so we’ve got a lot of stuff on the car, much of it under the bodywork.
“We’ve got quite a bit going on and we will certainly evaluate some of the stuff we’ve brought here in more detail at the test and test some bits for the future as well.”
Max Verstappen will be responsible for carrying out the comparison on Tuesday, and his teammate Carlos Sainz Jr. expects the feedback on the new parts to be positive.
“It’s difficult to say if the changes have worked or not because this is a completely different track to Canada,” said Sainz. “We have the test where we will back-to-back the new parts versus the Canada spec. Then we will take conclusions and we will say if it has worked or not – but it should.
“I’m looking forward to seeing what Max says about the back-to-back comparison. We are convinced it is working, but we don’t know how much we have gained or if it was what we expected.”
After Verstappen’s Tuesday run, DTM champion Marco Wittmann will take over at Toro Rosso on Wednesday in a BMW-organized reward for his 2014 title success.
Wittmann was due to drive a 2012 Toro Rosso at Imola last year but the run was rained off.
