"The wake from the front wheels tended to spoil the downforce of the cars behind, so taking away a lot of the furniture of the front wings and making them simpler is aimed at taking the dirty air and putting it on your own car, therefore disturbing the car behind less," explained Technical Director James Allison.
"The challenge for us has been to try and recover the management of this tyre wake," James added. "Of course, that means trying to find other ways of getting the dirty air away from our car.
"So, within the scope of these regulations, trying to find newer and subtler ways of managing the tyre wake in a way that restores performance to our car."
At the back of the car, the rear wings are 20mm taller and 100mm wider, to create a larger hole in the air for slipstreaming, while the DRS opening has increased by 20mm to boost its power and make it more effective.
On each side, the bargeboards are 150mm shorter in height and have moved 100mm forward, to help improve airflow, while the aero elements around the brake ducts have been simplified.
