What you need to do, is set your aspirations lower here. This game is a single seater formula game. It is not strictly an F1 game. Therefore, the car design in game is perfectly good enough.
I personally do not think or know if we will see that design until other single seater formulas adopt it IRL.
Although I say this. I do think the new F1 car design is an elegant one. Especially whilst harking back to the 1970's for its usually unseen design change (the use of ground effect).
Seeing as no team has released a car yet unless you work for a team how could anyone really know. Remember the horrible phallic noses? Those rule changes were supposed get better looking cars doing away with the stepped noses. So I'm reserving judgment until the first race.
Anyway, as for what the car looks like on your team page improving the in race simulation is probably just slightly more important than changing what the car looks like.
