McLaren brings Mercedes engine upgrade to Spa
McLaren will run Mercedes’ latest-specification F1 power unit on both cars for the first time at this weekend’s Belgian Grand Prix, two races after it debuted on the works Mercedes in Austria. The team delayed the change because it still had mileage to use on its existing engines after cycling through components amid 2026 reliability problems. McLaren will also introduce a new rear wing at Spa, with technical director Neil Houldey saying it will be “tested and evaluated in Friday’s practice sessions” but warning that “we won’t be expecting any big change in terms of competitiveness.”

Alonso on Spa energy management dilemma
Fernando Alonso says teams face a major energy management dilemma at Spa-Francorchamps because the Belgian Grand Prix track is “very thirsty” and using battery deployment on one straight can leave a lap “finito”. Fernando Alonso said: "You cannot deploy in all the straights. Next week, it is going to be the same thing. If you deploy in Spa from Turn 1 (La Source) to 5 (Les Combes), it is finito for the rest of the lap. So, you need to save a little bit there to have deployment from Turn 14 (Stavelot) to the Bus Stop chicane. But if you deploy in those two straights, which is the optimal deployment, then there is one minute, sector two, with no deployment at all."

McLaren team principal Andrea Stella brushed off a question about what he would do in Laurent Mekies’ position at Red Bull, saying he is focused on fixing McLaren’s own problems.

He added that Mekies is “very capable” and “very competent”.

Orihara on Spa as a power unit deployment and reliability test
Honda trackside general manager and chief engineer Shintaro Orihara said Spa-Francorchamps will be a key test of energy deployment and reliability as Honda and Aston Martin look to learn as much as possible from their current power unit specification before introducing a new internal combustion engine after the summer break. Orihara said: "It will be a test for manufacturers in terms of energy management, so we need to consider how we will deploy MGU-K power on the long straights. The harvesting here is quite limited, even considering the circuit length. This puts more emphasis on getting the deployment plan right. The straights are also a demand on the power unit in general, not only for performance but also for reliability."
