Alpine slid back from fourth in 2022 to sixth last season, being stuck in no man's land some distance away from rivals McLaren and Aston Martin.
The Enstone team found it tough to continue adding significant performance to last year's A523, so Harman's technical team has opted to complete redesign the car ahead of 2024.
As well as running into the ceiling of how far it could develop the 2023 car, Harman says the wholesale design changes should yield a car that has a much wider operation window than its peaky predecessor.
"We maxed out the potential on the A523 and so the A524 is completely new from front to back," Harman said about Esteban Ocon's and Pierre Gasly's new car.
"We rigorously analysed the key aerodynamic concepts that we wanted to move towards on this car to explore more aerodynamic freedom and better unlock these concepts to their full potential.
