Hamilton and Bottas open attack on Verstappen with new engines at Spa

Lewis Hamilton and Valtteri Bottas will battle Red Bull Racing this weekend with new engines. Both drivers have put in their third and final power unit at the Spa-Francorchamps circuit. Logically, the changes are not accompanied by grid penalties.

Hamilton and Bottas will drive this weekend with a new exhaust, MGU-H, MGH-K and turbocharger. The engine development for this season is as good as frozen, so it doesn't look like Mercedes will have a lot of extra horsepower immediately. What could be the case though, is that the engine is more reliable now, which means it can be used for a longer period of time. Especially on Sundays that could be an advantage.

The customer teams will also receive new engine components in Belgium. Lando Norris, Daniel Ricciardo, Lance Stroll and Nicholas Latifi will also drive with new parts. Sebastian Vettel and George Russell are already driving the third engine of the 2021 season.

The Red Bull Racing of Max Verstappen and Sergio Perez will also be running with new engine parts this weekend, as will the men of AlphaTauri, Fernando Alonso and Charles Leclerc.
