Performance figures don't give an accurate picture of just how well a car performs overall. A given car may be the fastest to sixty, but that doesn't mean it has the highest top speed, tightest cornering or sharpest brakes. Lap times around a given track paint a more accurate, comprehensive picture of a car's abilities, but picking one track as the gold standard is dicey business. That's where Top Gear's Power Lap board comes into play.
Although weather conditions can vary, BBC's Top Gear puts all the cars through the paces at the same test track outside their studio, and what's more is that they're driven – or at least, so we're lead to believe – by the same driver: The Stig.
The latest high-performance supercar to make a run for the top of the record board is the Caparo T1, which, at 1:10.6, easily trounced the previous record holder, the Koenigsegg CCX, by an astonishing seven seconds. Unfortunately the Caparo was disqualified because, in its track set-up, it lacked the adjustable ride height to enable it to clear a requisite speed-bump. Caparo insists they deserve a second chance with a road-spec version. If the show's producers give the Ultima GTR an official run, meanwhile, the Caparo's reign as king of the Power Lap could be short-lived, adjustable shocks or not.
