The most cars loaded into a plane in one hour is 30 and was achieved by smart, TNT and TopGear Italy at Liege Airport, in Liege, Belgium, on 23 October 2008.

The whole attempt lasted only 35 m 45 sec. The attempt started once the cars (all smarts) had been placed on the palets near the Boeing 747 plane. And was over when the doors of the plane were closed and ready to take off.
