Not if the circle was made out of car parts.
A quote from jim about circles here.

So just get a couple of extra bumpers to attach to the doors to make a full circle of bumpers. And it would be extra safe if someone tries to run Harry off the road.
Simon Hogwood:
An interesting idea, but it begs the question of just how circular a circle needs to be - on one hand, you have a perfectly uniform circle (which is probably impossible to make outside an equation); on the other, a nonuniform shape - picture a rope with the ends tied together and thrown into a random but non-overlapping shape. Now, how far from the former to the latter can you go without the circle failing?
Did that make any sense? ???
Samldanach:
Hmm. Well, it certainly needs to be a simple, closed figure, at least in basic outline (though, it could be created from dozens or hundreds of complex, open figures, e.g. glyphs or other writing). I would also tend to think that it needs to be smooth. Corners would create inconsistent concentrations of magic, probably creating weak spots. The closer to a true circle you get, the stronger it would be (similar in principle to most structural engineering problems, in that many stress diagrams are based on true shapes).
So, creating a box around the car would probably work. You would tend to have issues at the four corners, where the energy would bleed off, possibly with visible effects. But, for the level of working you're talking about, it should hold together. (Of course, as cybrgrl pointed out, it still wouldn't actually help. I don't think there's any way to create a circle that would separate the driver from the engine.)

Make a circle around the driver's seat.
