WMSC approved radical change of the rules.

The principles of the technical and homologation regulations for the 2017-2019 WRC car were approved by the World Motor Sport Council. The intention behind the new regulations is to produce a car with a far more dynamic and distinct appearance that exhibits character and diversity. The highlights are:

Engine

- Powered increased to 380hp

- 36mm maximum diameter for the turbo restrictor

- Maximum 2.5b absolute turbo pressure

Body

- Free zone defined around the body shell of the production car to create a maximum WRC car width of 1875mm and greater overhang front and rear

- Greater freedom on the lateral parts of the front bumper, with potential for additional aero devices ahead of the front wheels. Openings may also be cut-out on the fender surface

- Bigger and more visible fixed rear wing

The overall weight of the car will be reduced by 25kg, there will be a return to an electronically-controlled centre differential and the overall homologated length of the car must be greater than or equal to 3.9 metres.

Looks like they realized that saving cost in a level where manufacturers are directly involved has no sense and instead decided to put everything on the appearance/marketing side.

By the way I guess that with 36 mm restictor they shall be able to reach more than 380 Hp. It's 19% of air more. If current WRC cars have let's say 340 Hp (I don't know) it shall bring around 400 Hp.
