Double wishbone fronts would make sense since the car is AWD and it would be a better front suspension to help the front motor put the power down to the ground. The rear remaining a strut based rear is very puzzling for various reasons (unless there were issues with packaging)
Edit: Found the Mission-R details here:
So it looks like there were packaging issues that affected their decision to use a McPherson based rear suspension.
That is a very odd combo (and one I was sure they wouldn't attempt with the GT4 RS). Double wishbones in front means the front axle will gain more negative camber as load increases. But with struts in the rear, the camber won't increase along with the front (causing some serious instability). I guess they are counter-acting this problem with electronic band-aids (able to control torque and braking of each wheel independently).
The good think about it is that you can tie the exterior and interior if you choose also blue inside. Looks good, personally I prefer Neodyme or black, but then the grey interiors would be a better match.
Always wondered if that was a typo if the car indeed had double wishbone front and struts rears, getting under the car and taking pictures would be the only real way to confirm that information.

Agree with all that the strut rear is a strange decision to be paired with a double wishbone front. This will make for some unusual dynamic suspension geometry.
But just look at that picture. The electric motor in this test vehicle is TINY compared to any Internal Combustion Engine. With a clean sheet design for an electric sports car, they could have made this rear suspension anything they wanted. In that picture, they have all the room in the world for a double wishbone or multilink rear design if this is just an electric car.
So the idea that the rear of this platform had to be McPherson strut only makes sense to me if this platform also has to support ICE powertrains too. So there are really only 2 explanations in my mind - 1)Perhaps the platform this concept car is based on is a 982 or 992 variant and because of that legacy of the platform, it was deemed too expensive to reengineer it to move the main rear hard points around. Or 2) (much more likely in my opinion) the next gen Cayman/Boxster will also have ICE drivetrain options.
