It has nothing "Mini" about it,it's just some jump rally or whatever they're called type of car with a shell to resemble a "Mini".
The same could be said of any racing/ rally/ drag car though, couldn't it? Loeb doesn't win rallies in a showroom fresh car. 74merc

The wheels are fairly heavy in a car, obviously not as great a proportion of the overall weight (I'm assuming, MX bike wheels are not heavy), and the bike wheels are of fairly large diameter, so amplify the effect.
There will have to be some effect though, otherwise we've figured out how to break the laws of physics.
In terms of 4WD, it'll have a bigger effect, all four wheels have a significant amount of inertia, and the car will want to rotate around each wheel in the same direction. I suspect in terms of the engine, it's the rotational inertia of the flywheel that will have the effect, as the engine will want to rotate in the engine bay in any case.
Didn't Peugeot have this problem in the eighties with the Group B 205 T16? I think the engine was transversely mid-mounted, so whenever it left the ground and the revs rose, the momentum of the crankshaft could upset trajectory of the car. If memory serves me well, they enlisted the help of Aerospatiale to correct this using aerodynamics.
i was going to say this too, i think that ari vatanen discovered this trait , which ultimately resulted in a large accident in one of the early t16's. every thing spinning in the same direction was what i understood to be the issue.

this was more impressive IMO

each wheel probably weighs more than that "mini"

This is the craziest one I've found :-

Suspect the second was accident rather than design, but even so!
Now those are proper backflips! http://www.youtube.com/watch?v=L-l-hvIJEYE

Have to say my all time favourite is this though. A double flip with twist and a backwards landing!

If you look close enough you can see brown streaks http://youtu.be/TtV1DZ3imW0
Travis Pastrana has been trying it for a while. Apologies for the quality, it's the only one I can find

Didn't Rhys Millen do a backflip in car a couple of years ago?
http://www.youtube.com/watch?v=gDsdhUesC2IHe failed on his actual run though...
