Renault's Robert Kubica has pointed out that those teams running the most efficient f-duct systems are likely to benefit lap time-wise in Belgium this weekend.
Although the tool - which Renault is running for the first time at Spa - allows drivers to manually control airflow to the car’s rear wing whilst on straights, Kubica explains how overall lap times can be reduced.
“We have seen a tendency for cars running the f-duct to use higher downforce levels than normal, because they can stall the rear wing and still generate good top speed,” the Pole began.
“I think that will change the approach to Spa, too, because teams will be able to run quite a lot of downforce and still achieve good top speed. Although this is a circuit we all like driving on, it’s still a track where car performance is very important.”
"Let’s say that on paper the f-duct should be a big step forward in terms of lap time gain, so we are obviously keeping our fingers crossed that we can maintain the pace that we had in Budapest," added Team Principal Eric Boullier.
