Watch the Lambo Sesto Elemento

Only Lamborghini can make a 999kg tutorial in physics more interesting than watching a monkey in a cowboy outfit riding a dog. Seriously. The car above, you'll know, is the Lamborghini Sesto Elemento, and we've just seen video of it going around a track.

After riotously crashing the 2010 Paris Motor Show and stealing everyone's thunder, Lamborghini did the decent thing and announced a tiny production run of just 20 examples, sold to enthusiasts who could use them on tracks - and tracks alone, like Ferrari's FXX programme - to play with.

So here we have one such play session. It's a bit shaky, granted, but you get a real sense of the engineering integrity and the...OK, no you can't. All you can do is ruddy hear it, and it sounds great.

But there is proper integrity contained within those jet-fighter lines. Lamborghini is fast mastering the art of carbon fibre, and this Sesto's full of it. Literally. ‘Sesto Elemento' actually translates as ‘sixth element' (which is carbon, on the periodic table), and the simple premise of power-to-weight means this thing, with its Gallardo-sourced 5.2-litre V10 manages a ratio of 562bhp-per-tonne.

That also equates to a 0-62mph time of 2.5 seconds - exactly like the Bugatti Veyron. Sheesh. Have a watch of the video below - it's Batman on a trackday! - and then follow the links below for more Lamborghini goodness.
