After a strong start to the season, Aston currently lies second in the constructors’ world championship table despite being outpaced on occasion by rivals Ferrari and Mercedes.
Fallows says that it is natural that the Silverstone outfit eyes the currently-dominant Red Bull as a reference, and he admits that the AMR23 can be improved in all aspects.
"We need to sort of consider where we are relative to the Red Bull,” said Fallows. “But I think there are areas we believe where we're relatively strong.
“Also, we have to optimise our car for every particular circuit, which means that sometimes there may be aspects of whether it's low-speed, high-speed corners, which aren't quite as strong as some other competitors.
“The Red Bull as a concept has been evolved for a bit longer than ours. We obviously very publicly went to a different concept early last year. We are still developing that.
“We think we've made a very big step this year, but we still have a little way to go. And I think honestly, I wouldn't point to sort of one single area of it. I think we just need to improve everything, really.”
Fallows indicated the Aston Martin is a good all-round car, with no particular vices.
"It's not necessarily that I think our car has particular strengths in some areas,” he said. “I think we have managed to generate a car which is reasonably capable in a lot of different areas. We can tune it to what we believe is the optimum for that particular track.
“There are certainly areas that we are focused from an aerodynamic and mechanical point of view that we think we can make progress. But honestly, I don't look at it as a car that has any significant weaknesses at the moment.
“It's just that we want to kind of build on the speed that we have and keep going with the same philosophy."
