Fernando Alonso will complete the remainder of the Austrian Grand Prix weekend using Honda’s ‘Spec 2’ Formula 1 engine after a problem was found on his updated power unit following Friday’s practice sessions.
After a difficult start to the season with Honda’s struggling power unit, McLaren was handed a boost heading into the Austria weekend when the Japanese manufacturer confirmed it would be introducing its ‘Spec 3’ engine after a successful practice run two weeks ago.
Both McLaren and Honda seemed happy with the updated power unit following practice as Alonso and teammate Stoffel Vandoorne finished inside the top 10.
However, Alonso will now move back to the ‘Spec 2’ power unit after Honda discovered a problem on his upgraded internal combustion engine (ICE) following FP2.
“Last night we detected an issue with Fernando’s MGU-H. We have changed his PU,” a spokesperson from Honda confirmed.
“All newly fitted components have been used during previous grands prix so there will be no penalties.
“The ICE will be Spec 2 from day two in Azerbaijan.”
