It’s quite strange that the windscreen is sharp and bonnet blurred, maybe up/down movement as well as linier movement? I have noticed this on some of my shots to some degree too.
Nice capture and composition though the movement does work for this for me too.

The lower the speed the more parts of the car will be unsharp, as they are all moving in different speeds relative to the image plane in the camera. The fact you've got one bit (acceptably) sharp means your panning technique is basically good. Choosing the most effective shutter speed is the tricky thing and comes down to experinece and analysing your shots.
Certainly gives the impression of speed.

That's what I couldn't understand either.

Now that's a thought. Hmmm....

Ah, that's a relief, honestly. I've thrown so many images out that I was beginning to doubt myself.
Thanks, fellas!
I agree that getting one part of the car sharp shows your panning technique is absolutely fine: if something is sharp, it would have to be.
I wondered if DoF might have been the cause, but looking closely it does appear more like motion blur than OOF blur, so I'll have to bow to krimage's comment about different parts of the car moving at different speeds (relative to the image plane in the camera) - can't quite get my head around that one! I'd be interested to know what the aperture and shutter-speed settings were. I've photographed cars at speed (on hill climbs) and not been aware of that problem.
I know exactly what you mean about making the best of what's there. Without a spectacular jump, bend, water-splash or whatever, it's hard not to produce something that might as well be a parked car! From what you've said I think you have indeed made the best of what you had available. Generally if I can't find anything better I look for some place where they'll at least have one wheel off the ground while cornering, though a panning shot on a straight such as this can be very effective too.

I've thought about it further and I think I'm getting my head around krimage's comment now. Although, physically, the whole car is moving at the same speed, because the car is moving both across and towards you, those parts closer to you will cover a large distance in the 2-dimensional plane than the parts that are further away (in much the same way that objects closer appear larger than objects farther away). However, i'd think that you must have been on quite a slow shutter speed for that to become obvious. If your 70-200 is the IS version then perhaps you've been able to eliminate camera shake with the IS at a slower shutter speed, hence the motion blur. Having said that, your panning technique must be very good indeed to have got shut a pin-sharp image at any point on the car, so although you might be disappointed with some aspects of the shot, you ought to be pleased with the panning at least!
Aside from ALL that, I do like the effect! It certainly has managed to convey a sense of speed and movement, and because the most important part of the car is sharp, this works well. Perhaps you ought to make this a speciality, a personal style if you like!!!

Interesting, interesting. Well, that certainly does make me feel a little better. And it also confirms the conclusion I have drawn in the meantime myself: I should have chosen a faster shutter speed. I found a racing (panned) image on here the other day that I liked, and the photographer gave his technical details. I was surprised that at 1/100 he managed to blur the background and got the car sharp from back to front. So instead of 1/60 and 1/80 maybe I should have tried 1/100 or 1/125. Maybe the cars go fast enough anyway to blur the background when you pan, even at that shutter speed.
Thanks for thinking with me on this!
