Coandă effect
With the double-DRS "Device" shelved for the foreseeable future, the team instead turned their attention to the exhaust, introducing a Coandă-effect system for the Korean Grand Prix. The system, also used by McLaren and Ferrari, used the curved shape of the bodywork at the rear of the car to guide the flow of exhaust gases, creating a low-pressure area over the car's diffuser. The team had previously considered launching the car with a Coandă-effect system, but opted to start the season with a conventional exhaust layout as they felt it was more important to start the season with a car that they knew was competitive rather than attempt to understand both the car and the complex properties of the Coandă effect at the same time.
