The 2023 Aston Martin will feature "clever innovations" thanks to the team exploiting "small loopholes" in the regulations.
The AMR23 – which will be revealed on 13 February – will be 90 per cent new, according to Deputy Technical Director Eric Blandin, as the team look towards a positive start to the season.
"We took all our learnings from last year's car and applied them to this year's car," he said in an interview with Aston Martin.
"So much of the AMR23 is new, it's completely different from the AMR22. We've changed more than 90 per cent of the parts and more than 95 per cent of the aerodynamic surfaces are different."
It will be the first car raced by Fernando Alonso for the team after the Spaniard tested the AMR22 at the Abu Dhabi 2022 post-season test, an experience he spoke positively about.

AMR22 became a 'laboratory' for 2023 car
At the start of 2022 the AMR22 struggled for pace, but Aston Martin's change of car concept at the Spanish Grand Prix proved to be a lifeline for the squad in helping them break into the midfield battle for points.
Blandin said the car became a "laboratory" to understand which concepts worked, enabling them to seek out performance for their 2023 challenger.
He explained: "The AMR22 became a laboratory. We tested so many things on the track to further our understanding and that growth in understanding was underlined by our improved performance towards the end of last season."
According to Blandin, the launch-spec version of the AMR23 is complete and will be fully revealed in February, instead of using a mock-up concept with their 2023 livery.
"The AMR23 is on target. From an aerodynamic point of view, the launch-spec car is complete," he added.
"All the aerodynamic surfaces have been passed on to the drawing office which has finalised the last drawings for car build.
"80 per cent of my time is currently focused on the aero department – on delivering an ambitious programme of updates for the season.
"Launch is important but it's only a stepping stone; we need to develop the car throughout the campaign."
