Thanks to a certain friend of mine, I got my hands on a scan of the Yu-Gi-Oh! 10th Anniversary Animation Book.
バラドックスのD・ホイール
時空を越える性能を持つ。
さらに変形機構も備え、なんと空を飛ぶこともできる驚異のD・ホイールだ

Paradox's D-Wheel(Duel Runner)
Performance that transcends time and space.
It is also equipped with a transforming mechanism and can even fly!
時空を越える力
遙かな未来から「デュエルモンスターズ」の力を求めて.
遊星、十代、そして遊戯の時代へとやってきたバラドックス。その時空を越える力を持っているのは彼の操る"D・ホイール"だと考えられる。
遊星の時代にも存在しない高度な機械だ。

Power to transcend time and space
Seeking the power of “Duel Monsters” from the far future.
Paradox has come to the time of Yusei, jaden, and yugi. It is thought that the power to transcend time and space is possessed by the “D-Wheel” that he controls.
It is an advanced machine that does not exist even in Yusei's time.
The Paradox D-Wheel's ability to travel through time and space is through performance. I think it might not mean speed though, it might mean it might be like a time machine? Certainly the dubiousness of its feat is worth discussing
