Toro Rosso technical direc♏tor James Key says the team will retain its low drag philosophy with its 2015 car.

While Toro Rosso went for a low drag design with its car in 2014, part of that decision ꦗappeared to be out of nec💎essity due to the weakness of the Renault power unit. However, when asked if the team would be retaining that idea with its 2015 car, Key replied: "We have because we believe there's a bit more to be found there."

Explaining the trade-off between drag and downforce, Key said Williams - another team to opt for a low drag design this season꧋ - had shown what is possible with a stronger power unit.

"As you pile downforce on so it becomes more difficult to get a gain from it. It's a very non-linear thing and efficiency 💧is always important but even more so when you're ope🏅rating at high-downforce levels. These cars, it's difficult to tell when they're going to flatten out from a downforce perspective. We haven't at the moment, I'm sure it will come. But when you do it's drag reduction and I think what Williams has done has been extremely effective.

"So we'll have to see. Iไt's power unit related. We tend to have a little bit of a low drag philosophy because when you come to Sunday you know that's going to be pretty important unless you're sitting at the front. So it's a good thing in my eyes. But then you can still do that if you hit peak levels - let's say a Monaco level of downforce - if you're good there you can still come back and it's probably a nicer place to be. So the more downforce you get it's always better."
