The subaru impreza WRX racing car version has boxer engine (horizontally opposed piston/cylinder assembly) only used in some model of Porsche, which enables these cars to have extremely low center of gravity. The normal-road version of these cars don't have boxer engine for reduction in price.
Also, it is one of the most popular cars in Australia and one of the most snatched cars too so they have a pretty neat factory installed anti-theft system the engine immobilizer jams the engine if the driver side door is opend from the outside after car has been running.
