how is this done?

Theres a bit of Photoshop work as well. The yellow lines and background are not distorted as the cars.

Not sure about that - I think the decidedly dodgy rear wheel on the punto is confusing matters, I'd say there hasn't been any correction applied anywhere in the image.G

Not sure what aspect you're interested in, but unless I'm missing something obvious, an ultra wide angle lens (eg 10mm) would account for it.
I'd say that due to the perculular distortion, cropped wide angle/fisheye image or even perspective control lense?Either way, the images have almost certainly been cropped

Bit odd, I'm assuming a crop from a ultra-wide angle or even a fisheye.
People assume fisheye = mental distortion, but with certain framing they can look fairly conventional throughout most of the frame. Looking through my pics, this looks a bit similar to those posted above, taken with a Nikon 10.5mm Fisheye on a crop body (D90)...

No massively noticeable distortion throughout most of the image, but some severly curvy buildings at the edges (much like the cars above)

Part of the high price of that lens price is lower distortion - and you had the horizon roughly in the middle, whch helps a lot.You can deal with some or all barrel distortion in processing, but you end up with (ironically!) a pincushion-shaped image which then needs cropping back to rectangular.

A 10.5 Fisheye will distort far more than a "normal" 10mm lens. Hence the "fisheye" bit.
My understanding is that a true 'fish-eye' lens produces a circular or near-circular image, whilst the more you pay, the more it resolves the image (with the same FOV) into a rectangle - which is the clever bit.You may be right Simpo, that's not how I understand it though although it wouldn't be the first time I've been very wrong. I remember I once asked which lenses in Nikon's zoom range were the "prime" ones because those were the ones I wanted.
My understanding is that a rectilinear UWA lens (such as the 10-20 sigma) is corrected for barrel distortion whereas a fisheye is not - mainly because they generally have a wider field of view.
I've tried to find a comparison photo set of a fisheye vs a UWA lens and naturally I can't find anything useful.

Anyone can acheive this same effect by cropping._dobbo_ said:

As far as I can see the example photos in this thread are quite simple 10mm wide angle shots with no cropping or any correction.
I really don't understand how you arrived at that assumption....... for example; take the image of the yellow Seat? - the bonnet area is the most pronounced & therefore would have been the centre of the original image. To achieve this effect it must have been cropped to give the impression that the car was distorted towards the lower R/H corner.As far as I can see the example photos in this thread are quite simple 10mm wide angle shots with no cropping or any correction.
As for the silver Punto & in hindsight, it appears to have a rediculous amount of positive camber dialed in on the actual car & not due to lense distortion or P/S.
I have to admit that it's a clever way of giving a different perspective to W/A & Fisheye photography & something I will definately consider doing myself in future
