Porsche has released a new video that explains some of the characteristics of the 2014 911 GT3 that made its debut last week at the Geneva Motor show. Looking like a more aggressive 911, the GT3 version features extended side skirts, different rear bumper, optional LED headlights, a fixed rear wing and bigger spoilers. It sits on 20-inch forged alloys and comes with a center-mounted dual exhaust system. This is the first model offered by Porsche with an active rear wheel steering system which can steer the rear wheels in the same or opposite direction of the front wheels for better agility on track. It’s powered by a six-cylinder 3.8-liter boxer engine rated at 475 HP, allowing it to sprint from 0-62 mph in only 3.5 seconds.
