Kind of reminds me of the old Aerovette.

Cameras for mirrors means it won't be legal in most countries I'd think.

"The design is one of pure, streamlined elegance. Born out of the single-minded vision to create the most aerodynamically efficient car ever, there is an uninterrupted flow of air from nose to tail." Beautiful car. It is interesting that they have designed fixed carbon fiber wheel covers for the front wheels but nothing was done to smooth airflow over the the rear wheels. Any guesses why not?

Is the car for homologation? If so,the sanctioning racing organization may have some say in the car design.

front wheel discs/covers are fixed to the hub

I thought the images of the car's front wheel discs were unusual for their asymmetry:




That made me wonder if they rotate with the wheels or not. Turns out they do not!

I don't believe so--according to every news outlet I've seen, this is McLaren's take on the ultimate grand touring car. (Which I feel conflicted about, because no car that costs $2.5 million and has only 106 examples built will ever be taken on a road trip).*

That said, if they're shooting for "most aerodynamically efficient car ever," I suspect they have a ways to go. The car looks significantly bigger than, say, an XL1 and has no plan taper. I will be very surprised if it's sub-Cd 0.25.

*Also, where the hell is luggage for three people supposed to go? Send it up ahead with your convoy while you motor in style? The "ultimate" grand tourer should account for that, I feel.

I'm usually not so overwhelmed by "extreme" aerodynamically-oriented projects, but this one is great-looking. Gotta have to get used to cameras replacing mirrors though...
