The Impreza is athletically styled, avoiding the bulbous look that plagues some hatchbacks, including the Pontiac Vibe. One of the 2.5GT's most noticeable styling features is its hood scoop, which directs air to the intercooler that's mounted atop the engine. The scoop is better integrated into the hood than some of Subaru's previous ones, but it's still large.

The rest of the 2.5GT's styling is fairly reserved. Smooth body panels give the car a clean look, and a noticeable crease above the door handles stretches from the front fender all the way to the rear quarter panel, adding an interesting design cue. The back of the 2.5GT hatchback is finished off with a forward-sloping liftgate and a small spoiler.
