Eric Boullier says he is "extremely disappointed" by McLaren's performance at the Russian Grand Prix, as the team continued to be hampered by Formula One engine partner Honda's reliability problems.
McLaren's woeful start to 2017 continued in Sochi as the Woking-based outfit once again missed out on a points finish, leaving the team rock-bottom of the constructors' standings after four races. After receiving the first engine-related grid penalty of the season and having started from the back of the grid, Stoffel Vandoorne at least managed to take the chequered flag in 14th, while Fernando Alonso failed to even take the start, following the latest failure in his MCL32.
