Apart from a big, two-planes rear wing, main features of the new car are the front flaps on both sides of the car and the big and prominent rear diffuser.

This is the only 2017 WRC car to use dive planes in front of rear wheels, as shown in pictures above. They are designed for generating downforce on the rear train, but also for redirecting air towards rear brake inlets, so improving brake cooling.

Details from the car configuration used during 2017 season obtained in Rally Catalunya are shown in pictures below.

Picture from Nacho Mateo in Rally of Germany confirms holes over diffuser are blinded, so there is just one slim diffuser.
