Otmar Szafnauer has revealed Aston Martin is approaching the upcoming campaign with a sense of "trepidation" due to the extreme regulation changes.
F1 cars are set to look very different to those of recent years due to new aerodynamic regulations that include the introduction of swooping front and rear wings and the removal of winglets.
Described as a "blank sheet" by McLaren executive technical director James Key, the changes have the potential to shake up the established order.
In an interview with GPFans in December, Szafnauer said the changes provide "uncertainty" that "can bring trepidation".
He added: "That uncertainty will soon go away. We are two months from testing the car.
“We've got a great tunnel that we use, we've expanded the aero group, we've got some good guys from some of our competitors that have started and we had a good bunch anyway.
"So with all that, we should be looking forward to a good season.”
Six days of pre-season testing will be split between Barcelona and Bahrain, with the former hosting the first three-day test between February 23-25, and the latter on March 11-13.
Szafnauer added: “That [the time] will go by fast and then we'll be running the new cars, and we will see what we've got.”
