Jeremy Clarkson in RenaultSport Twingo - from Top Gear
In an episode from last fall, the ever-mischievous Top Gear found out. Host Jeremy Clarkson barrel-rolled the RenaultSport Twingo 133—at about 37 mph—in a Belfast sewer (as seen in the clip below), keeping the roof intact.
Tip: You can be reassured that the car didn't stay intact for long, though; Clarkson later in the episode jumped it off a Belfast pier.
And the harshly lit tunnel and movie-like soundtrack makes it look a bit Back to the Future, as if he's about to disappear in a poof.
