McLaren has changed the power unit on Fernando Alonso’s MCL, reverting back to the ‘Spec-2’ Honda engine for the remainder of the Austrian Grand prix race weekend.
Both drivers were scheduled to use the new more powerful upgraded engine in Austria but an MGU-H issue detected on the Spaniard’s unit prompted Honda to change back to the previous engine.
