The A524 was launched on Wednesday at the team's Enstone base, with Technical Director Matt Harman describing how the team had thrown away much of last season's car - with only the steering wheel surviving.
Alpine slipped from fourth to sixth in the Constructors' last season with most of the senior leadership departing with CEO Laurent Rossi, Team Principal Otmar Szafnauer, Sporting Director Alan Permane and Chief Technical Officer Pat Fry all leaving, with Fry resigning to move to Williams.
Bruno Famin was brought in as interim Team Principal to steady the ship, with Alpine making good progress over the second-half of the season, culminating in Esteban Ocon claiming fourth in Las Vegas - races after Alpine struggled on a similar track at Monza.

Gasly on Alpine's momentum
"I must say it's been good," Gasly told media including RacingNews365 when addressing the atmosphere within the team over the winter at the launch.
"Overall, last year was a disappointing season, we didn't perform the way we wanted, but in the second part of the season, it felt like [we] maximised [our package] slightly more.
"There were definitely some changes and a big desire to improve the potential within the team and trying to drive that mentality into the race pace.
"From what I've seen, I'm really happy with the changes so far, the atmosphere is great, spirit is good and I am in a great place as well.
"I just want to get behind the wheel, and am very happy with the engineering team I have around me, and we have a better understanding of what we need both as a team and myself as a driver.
"The team has understood well what the sort of characteristics are in the way that I work and we are doing really well, so it is mainly about keeping that collaboration going keeping together that way of working that we finished the year.
"I must say I am quite confident to start the season from where we left off."
