We know you. If someone tossed you the keys to a spanking-new 2008 Subaru Impreza WRX STI for the weekend, you'd make a beeline for the nearest winding road leading into the mountains. So would we. But would you also bring along your wife, two kids and mother-in-law, all prone to carsickness? Not if you could avoid it. But we couldn't. Such is married life. Besides, Mom was the one with keys to the cabin. Normally, the mere sight of an old-school STI or Evo complete with a boy-racer wing would have been enough to elicit a Pavlovian response from this bunch, with the gut-churning getting into high gear even before we reverse out of the driveway — but such was not the case this time. Because the 2008 Subaru Impreza WRX STI is based on a sensible wagon-esque five-door hatchback body instead of a sedan, it somehow managed to slide under the radar of civilians. Good thing, since this revised, turbocharged 2.5-liter flat-4 engine puts out 305 horsepower and it makes the 2008 STI go like stink.
