Watching LawVS' latest video and he noted that while they are using Ferrari's gearbox internals, Cadillac has developed their own gearbox casing which gives them the ability down the road to run their own rear suspension geometry if they choose, rather than having to use the standard Ferrari one (like Haas has to).
I found his insights that with batteries now making up half of the total power output and how battery management will be an even more crucial strategy differentiator, could this mean that:
a) Formula E becomes a viable ladder series into Formula One for drivers, and;
b) Could F1 teams that also have Formula E teams use the knowledge those FE teams have about electrical propulsion to improve their F1 PUs?
He brought up how the Cadillac F1 and Andretti FE operations are ~50km apart which would facilitate staff travelling back and forth to assist each other. And how teams like McLaren, who have zero presence in Formula E, might be a bit on the back foot.
And speaking of Ferrari and rear suspensions, the 2026 car has returned to a pushrod configuration after 15 seasons running a pullrod configuration.
