After four generations, Subaru Legacy's 2008 midsize model gets a revamped image with upscale styling and a new top-line sedan model with a six-cylinder engine. The addition of the WRX STI's turbo-charged engine places the powerful Legacy GT in a category otherwise occupied by cars of European origin. Legacy offers sedan and wagon body styles, available in 2.5i and 2.5 GT trims, with all-wheel drive and horizontally opposed engines.
