The Duel Runner, known as D-Wheel (Ｄ・ホイール, Di Hoīru) in the Japanese and German versions, is a special Duel Disk extension, developed by KaibaCorp introduced in Yu-Gi-Oh! 5D's for Turbo Duels. They are equipped with a screen which shows details like the current duel field or the Life Points. It can approach speeds of up to 220 kilometers (136.62 miles) per hour during a Turbo Duel. In addition to this, other equipment like the helmet visor serve to display various information, such as the stats of a monster.
In each Duel Runner, there are two specific cards integrated: the Field Spell Cards "Speed World" and "Speed World 2". If this card is activated then the duel screen on the Runner will appear. Furthermore all other information irrelevant to the Duel, can be switched off. "Speed World"/"Speed World 2" also activates the Duel Disk, which is attached to the Duel Runner.
Consequently Duel Runners have been seen to posses certain other distinctive characteristics seen on the series. Such to be mentioned are runners that are hybrids with Card Zones that can be detached and used as standard Duel Disks. Some that have sidecars with their own Card Zones attached for Tag-Team Duels. And to be pointed out its possible to have a regular Duel on Duel Runners as long as "Speed World" is not activated.

In the series, even though Duel Runners are primarily designed for Turbo Duels, they also serve as alternative forms of transportation.
