As you may recall the car achieved a lap-time of 6:47.5, which may not upset Radical, but probably left engineers at Ferrari and Porsche feeling a little miffed. This video tells you why they bothered.
The vid has been around for a little while, but as we missed it the first time we thought some of you may have done so too. Or hey, why not watch it again!
(Just in case you missed this one as well, here's the official video of the full lap that we showed you back in July.)
