I love what they've done to develop that nose and front section further compared to last year. Look at the shape of it and imagine where the air goes. Air attaches to the sides of the nose section which they've narrowed the profile of greatly compared to last year, the bodywork gently expands out and directs and likely accelerates it into the ducts. The nose duct is a great example of getting as much out of an element as possible. It's not just some dumb lump of carbon fibre that air hits.
Most teams have moved in a Mercedes type direction, but it's the details. Simple, simple stuff, nothing complicated, but it's details like that that set Newey's cars apart. You contrast that with the Ferrari and they just don't seem to have moved on.
