Ferrari president Luca di Montezemolo has renewed his attack on Formula 1's slowest cars - claiming that if outfits are not quick enough they should not even be allowed to take part in grands prix.
After seeing Fernando Alonso's chances of victory in the Canadian Grand Prix wrecked when he lost time and momentum behind backmarkers, di Montezemolo has again hit out at the backmarkers.
"Cars who perform at GP2-level should not be allowed to participate in F1 races because they are supposed to race on Sunday mornings," di Montezemolo was quoted as saying by Gazzetta dello Sport.
"Our car's race pace was good enough for victory. Let's hope that, in the future, there won't be mistakes in pushing a button nor in lapping cars that put us at a disadvantage, because we've already gone through that."
Di Montezemolo has said on several occasions that F1 would be better off allowing the big teams to run three cars, rather than bringing in new competitors to boost the grid.
