AlphaTauri put its 2021 car through its paces at Imola on Wednesday, with Pierre Gasly and rookie Yuki Tsunoda in action at the wheel of the AT02.
The Faenza-based squad's new contender appeared at Autodromo Enzo e Dino Ferrari sporting a different nose and front wing than the design showcased at last Friday's launch in Salzburg.
AlphaTauri devoted both its development tokens to an overhaul of the AT02's nose design and front suspension, as the team's technical director Jody Egginton detailed last week.
"We've elected to use our two tokens for a new nose and also redesigned the outboard front suspension," said AlphaTauri's technical director Jody Egginton.
"As a result of this we have elected to update some Red Bull Technology-supplied steering components to 2020 specification, as permitted by the technical regulations."
"The headline aero numbers have been affected by the aero change, but we have been working really hard to recover the lost performance and also improve the aero dynamic operating window for the car.
"How fast will our car be? It's not something I would want to put an exact number to just yet.
"Overall, taking everything into account, I would say we will probably see a performance level similar to that seen mid-2020."
