Toyota used the 2003 Corolla platform and mechanics and liked the concept so much that it asked GM if it could build a version of its own—the Matrix— with different lines, to which the American automotive giant agreed. The Matrix is available in base and XR trim in two- and four-wheel drive, with an XRS front-wheel drive version also available. The latter has a 180 h.p. engine and a six-speed manual transmission.
