Supersecret Leisure Stig
The Leisure Stig is one The Stig's many cousins, and was featured in the Final Series 22 Episode. Unlike the rest of the Stigs, the Leisure Stig is not a very good driver, and is only used for leisure purposes and testing caravans.
The Leisure Stig has a relaxed driving style like the American Stig, but drives even slower, so much so that even James May got impatient being stuck behind it. It raced with all three presenters in a towing caravan race, and it soon got bored after doing 20 laps.
Then it set a benchmark time using a Kia Sportage in an acceleration and braking test. None of the presenters' SUV managed to beat the Stig's benchmark.
