Two SUVs with some similarities, but otherwise different in most aspects such as the model year, horsepower, fuel economy, ground shadow size, and maximum occupancy.

Also, the Envision has a slightly smaller body than the Highlander Hybrid. In addition, the Toyota Highlander Hybrid seats two more passengers than the Buick Envision.
