The Belgian Grand Prix venue is famed for its lengthy straights and demanding climbs, significantly by way of the long-lasting first sector which takes drivers from La Supply, up Eau Rouge and Raidillon, alongside the Kemmel straight and braking for Les Combes.
However very similar to Silverstone’s lengthy straights and minimal heavy braking zones, Spa will pose the brand new F1 automobiles with a deployment drawback given the few locations to sufficiently recharge the battery pack throughout a lap.
Alonso expects drivers to have the ability to use their total battery within the first sector having charged it on the Bus Cease chicane and La Supply, however then haven’t sufficient braking zones to regain the vitality for the high-speed second sector.
“Silverstone and Spa, they’re very thirsty on vitality,” Alonso stated throughout the build-up to the British GP. “You can not deploy in all of the straights. Subsequent week, it’ll be the identical factor. In case you deploy in Spa from Flip 1 [La Source] to five [Les Combes], it’s finito for the remainder of the lap.
“So, you should save a bit of bit there to have deployment from Flip 14 [Stavelot] to the Bus Cease [chicane, Turns 18 and 19]. However should you deploy in these two straights, which is the optimum deployment, then there’s one minute, sector two, with no deployment in any respect.
“And with no deployment in any respect, we can’t overlook that this 12 months we’ve considerably much less energy than final 12 months and fewer energy than F2. That’s the case while you lower the deployment. So, sure, it’s a problem.”

It must also be pressured that F1 automobiles with deployment will nonetheless be comfortably faster than F2 automobiles. For instance, Kimi Antonelli’s pole time at Silverstone was a 1m28.111s, whereas in F2 Rafael Digicam’s pole lap time was a 1m39.690s.
Alonso’s sentiment was shared by different drivers on the grid, with Spa rated because the worst for F1’s energy unit guidelines alongside Silverstone, Monza and Suzuka.

“Let’s not converse too quickly as a result of we’ve Spa subsequent week… possibly Silverstone will really feel mega in comparison with that,” Bearman added final weekend.
“I like Spa, however Spa goes to be one other painful one, simply due to the vitality, like right here,” Verstappen additionally stated at Silvestone.
F1 has already moved to handle the issue each for this 12 months and into 2027 and 2028 by decreasing the reliance on deployment vitality, finally shifting the ratio of inner combustion to electrical motor output from round 50/50 to round 60/40.
