Stroll said it was “just a difference in grip and performance”, and asked how the team would improve, he said: “I don’t think it falls from the sky. I think you have to improve and find performance in the car and the engine.”
The Aston Martin design was described by Newey at the team’s launch earlier this week as “one of the more extreme interpretations” of this year’s new rules, and it has drawn admiring glances from rivals.
But so far the car has not shown any signs of performance, and the same can be said of the new engine designed by Honda, who have switched to Aston Martin this year from Red Bull.
The 27-year-old admitted that “a big part” of the car’s problems came from the engine. Asked whether there was anything positive he could say about the car, he said: “The livery looks nice.”
On Newey’s role as team principal, a position he took on in November in addition to being managing technical partner, Stroll said: “He’s all about performance. He’s just obsessed about how he can bring more performance to the car and he’s a great leader overall.”
Newey joined Aston Martin only in March last year and the team have been careful to play down expectations for their first season as a works team.
Stroll said: “We are where we are. Do we want to fight for race wins? Yes. Are we fighting for race wins today? Doesn’t look like it. Does that mean we can’t fight for race wins in the future? No, I believe we can.
“I don’t have a crystal ball. It doesn’t look like it’s amazing.”
