Austrian aftermarket firm MS Design unveiled its Ford Focus ST Competition edition at the Geneva Motor Show. The modified model is equipped with a new front spoiler, revised side skirts and a rear diffuser, and also comes with a sport-tuned suspension, tailgate-mounted spoiler and 20-inch bi-color alloys. Given this is a styling package, the stock ST's 2.0-liter EcoBoost four-pot remains untouched, but the upgraded suspension and new alloys help it handle that much sweeter. The 0-60 time of 6.5 seconds is likely to remain the same, though.
