Looks like a Puma door hasn't yet closed for Mikkelsen...

Of course not. If you have money...

Loeb to Ford appears to be a done deal. Programme TBD.

The Puma testing car seems to have quite a lot of empty space in the wheelarches for tarmac spec car.

Could be for aero reasons.

Yeah sure... If you want to have worse aero you make the gaps bigger, and the ride height taller

Haha, ride height and wheel arche design are not strictly related. An enclosed wheel arch that is not sufficiently vented produces a lot of lift, if the regulations don't allow for openings (see Yaris CD stack as a prime example) to vent the pressure, one solution is to make the gap between the wheel and the arch bigger (see TC1 cars from the WTCC). It might sound counter intuitiv, but a lot of aero stuff does.

I guess they could find better solutions... such as the internal conduct at the rear of the new Toyota GR Yaris Rally1, an alternative to the CD stack

Yeah sure that can be a solution all though it is probably not a golden ticket in terms of drag either as its a bit of a bottel neck with a high pressure region somewhere. Also seems like a loophole they found as there was this talk about "no internal ducting"?

Right, it is possibly the less bad solution. I also thought about regulations when I saw it. If they're able to use it, it's probably because FIA allowed them and other teams agreed, or... Hope this does not cause any controversy in the future
