MONZA, Italy -- Sebastian Vettel was left frustrated after claiming Ferrari's slipstream tactics failed to play out as planned during qualifying for the Italian Grand Prix.
Vettel qualified fourth, 0.150s off teammate Charles Leclerc on pole position, but ran out of time before his final attempt at the end of the session and did not get an opportunity to improve. His first attempt was set without a slipstream -- a key performance differentiator worth as much as 0.4s on Monza's long straights -- but in doing so allowed Leclerc, behind him on track, to have a slipstream for the lap that ultimately claimed pole position.
