http://www.autosport.com/news/report.php/id/92717 Red Bull's motorsport advisor Helmut Marko says the team will lose half a second per lap with the introduction of a ban on off-throttle blown diffusers from the British Grand Prix.
But Marko is adamant the team has taken the right measures to make up for that with new set-ups and aerodynamic updates.
The ban, which is likely to affect most teams to some degree, will kick in in next week's race at Silverstone.
"We expect to lose approximately 0.5 seconds per lap without the blown diffuser," said Marko.
