Caterham SP/300.R

Remember the SP/300.R, Caterham's first new car since the 21, which was launched at the Autosport International Show back in January this year?

Well, we've stumbled across this footage of this new track car doing some hot laps at Donnington, so all of us can get an idea of what the lucky 25 owners will be experiencing in the 2012 one-make racing series.

It's not clear who's driving, but the performance certainly seems in-line with Caterham's claims of 60mph acceleration in just 2.5 seconds and a top speed of 170mph.
