When the Fox-body Mustang debuted in 1978, it was a return to form for the original pony car and a welcome departure from the malaise-era Mustang II. It's also missing from Ken Block's Hoonigan collection and was a problem he obviously needed to solve. Thus was born the Hoonifox — a Fox-body built to Block's lofty standards. The Hoonifox is still in the concept stage, but these renderings give a taste of the outrageousness to come. Angular widebody fenders — a Ken Block staple — are on full display, giving an idea of what a Mustang Group B rally car might have looked like in the '80s. Another '80s styling cue is in the flip-up ducktail spoiler, along with sharply-creased hood and roof scoops. Block hasn't quite nailed down the powertrain, with a naturally-aspirated V8 seeming to be in the lead. The Hoonicorn featured all-wheel-drive, so expect that to make it into the Hoonifox as well.
