Matrix loses its all-wheel-drive and sporty models for 2007. This five-passenger wagon shares a basic Toyota-sourced design and powertrains with the Pontiac Vibe, which differs slightly in appearance and features. Matrix comes in Standard and XR models, both with front-wheel drive and a 126-hp 4-cyl engine. AWD versions and the sporty 164-hp XRS are discontinued. Manual transmission is standard, automatic is optional. ABS and an antiskid system are optional. So are front side airbags and curtain side airbags. Among features included on the XR and optional on Standard are power windows and locks and remote keyless entry. New for '07 is an M-Theory option package with 4-wheel disc brakes and special trim.
