McLaren is expecting to make a step forward at this weekend's Austrian Grand Prix after engine supplier Honda confirmed both cars would race with its upgraded 'Spec Three' power unit.
After testing the updated power unit on Fernando Alonso's car during Friday practice at the Azerbaijan Grand Prix, McLaren and Honda opted not to risk running it in the race in the knowledge that its two cars would be starting from the back of the grid with penalties. However, after continuing to work on the power unit since Baku, Honda has confirmed that both Alonso and Stoffel Vandoorne will benefit from the upgrade in Austria.
