The first generation Premio and Allion were launched on 25 December 2001. The Premio sedan has a more elegant approach in comparison to the Allion, which has an emphasis towards younger buyers. The Premio and Allion share the same engines and interior. The Allion can be customized with front spoilers and rear mounted trunk wings, as well as ground effect body parts to enhance the vehicles appearance specially designed and sold by Toyota. The Allion also features rear tilting seats (similar to front seats). The Allion continues the Toyota tradition by being made for taxi usage, driving school and law enforcement versions.
