A side-effect of the new aerodynamic regulations in 2009 will be the slowing-down of pitstops, according to McLaren test driver Pedro de la Rosa.
In the name of inspiring more overtaking, drivers this year will be able to control from the cockpit a moveable flap on the front wing.
But because damaged front wings so often need to be changed during races, gone are the days when this process can be completed in little more than ten seconds, the 37-year-old Spaniard told the British broadcaster ITV.
"You can use a hydraulic system or you can use an electric motor, but whichever you use you still have to connect some type of cables because you're operating it from the cockpit," de la Rosa said.
"So it's going to add a big loss at the pit stops for everyone."
