Aston Martin and Haas are set to start both of their respective cars from the pit lane at Formula 1’s United States Grand Prix after undertaking set-up changes.
The teams have both brought heavily revised packages to the Circuit of the Americas and have had setbacks through the course of the weekend.
The situation has also been compounded by set-ups being locked in after the sole practice session that took place on Friday.
Kevin Magnussen and Nico Hulkenberg were due to start from 14th and 16th respectively while Fernando Alonso and Lance Stroll were set to line up from 17th and 19th on the grid.
“We learned the package is performing as we were expecting but we haven’t been able to optimise the set-up,” said Aston Martin’s Deputy Technical Director Eric Blandin.
“We will start both cars from the pit lane, and we are effectively changing the set-up, we think there is a lot more performance to come from the car.
“Lance is going to have the new spec, Fernando will have the Qatar-spec.”
Haas is also due to run different set-ups in a bid to understand more about its heavily revised VF-23.
As predicted, exposes the frailty of the Sprint Weekend Program with development/prototype F1 cars.
