Groups have lengthy used ballast to optimise weight distribution from observe to trace, though in recent times with the hybrid automobiles it has proved more durable for them to get under the minimal restrict in an effort to make the most of it.
Final 12 months, most groups have been considerably chubby and all have pressured that they’ve labored arduous to drop some weight from their automobiles over the winter.
Nonetheless, Alpine is the primary crew to state in public that it’s below the 798kg restrict with its 2023 automotive and is thus able to make use of ballast to achieve a aggressive benefit.
“We have had a really aggressive weight discount programme,” mentioned technical director Matt Harman. “And it is actually pleasing to have the ability to say that the automotive shall be underweight this 12 months.
“We may have ballast within the automotive, and we shall be transferring it round to optimise that weight distribution, which is a incredible efficiency device for us and our trackside engineering groups.”
Harman mentioned the give attention to weight-saving with the A523 began early within the growth section.
“It was fairly a technique there,” he defined when by Autosport about how difficult it was to get the load down.
“We truly stopped making an attempt to take weight out of final 12 months’s automotive to give attention to this 12 months’s automotive, as a result of there does come some extent within the season the place it is not cost-effective to take action. So we put a whole lot of engineering effort into that.
“And yeah, we have taken numerous kilograms off the automotive, which now provides us a pleasant ballast quantity that we are able to use for weight distribution. In order that’s superb.”

The foundations initially referred to as for a discount within the restrict to 796kg for 2023, earlier than it was agreed to maneuver again to 798kg.
Nonetheless, an FIA error in processing that change meant that it didn’t occur routinely, and subsequently a number of groups tried to dam it, as a result of they determined that they most popular the decrease restrict in spite of everything.
In the long run, the FIA used a rule that accounts for adjustments in tyre development to return to 798kg, however Harman conceded that Alpine was one of many groups that opposed the change: “Yeah, we might have been pleased with 796.”
Nonetheless, he defined that the crew can nonetheless achieve a bonus from ballast, the place tactical positioning will be to the automotive’s profit.
Harman revealed that the revised rear suspension was one of many key areas the place weight had been saved, though it additionally has different advantages.
“Not likely, as a result of we simply spend it again into efficiency,” he mentioned. “We simply managed that basically, actually carefully. It is not nearly being below, it has been about below at efficiency. I believe we’re fairly pleased with the place we’re proper now.”
“The rear suspension is a giant change for us. We modified ideas, we have come from a pullrod rear suspension to a pushrod for fairly a couple of totally different causes.
“Firstly, we have to take some weight out of our automotive. And we did have a really fascinating idea for final 12 months. However this one is extra fascinating, it is a bit of bit easier with a pushrod, and it’s allowed us to take an terrible lot of weight out of the rear of the automotive.
“Additionally, we put a bit of bit extra complexity into the inboard system such that we might have extra modularity for our trackside engineering crew. So we have to give them instruments to have the ability to arrange the mechanical stability of the automotive, and that is what they’ve.
“However most significantly, we have managed the airflow by means of there. It is a lot cleaner, there’s much less blockage in order that we are able to get extra air out from the rear of the automotive.
“That is actually essential and it should be growth for us as we transfer ahead.”
