With 37 days until the launch of Xbox One and “Forza Motorsport 5,” our friends at Turn 10 Studios have shared week four of the “Forza” Showroom car reveals, highlighting some old favorites, acknowledging some leaderboard stars, and saying hello to a new member of the Forza Motorsport series. The full list of cars we’ve announced so far can be found here. Be sure to stay tuned in the weeks ahead as we reveal more cars and share the latest "Forza Motorsport 5" news. 2012 Nissan GT-R Black Edition This Japanese supercar delivers straight-line performance that can’t be beat by cars five times its price. In the corners, traction from its high tech all-wheel drive system delivers astounding grip and predictability. The GT-R’s looks make it a standout in any field and true import lovers will bow in its presence. There are only a handful of cars that will do anything but linger in the wake of its exhaust should they try to step to it on the track. 1967 Lamborghini Miura P400 Forget the Sistine Chapel, this might be the highest form of Italian art. Without the Lamborghini Miura, the term supercar may never have come to be. In an age when the only race-derived designs came from Ferrari, the Miura demonstrated a bold new direction. The Miura was conceived and designed by three of Lamborghini’s top engineers of the time. The result was a car whose form was revolutionary, and whose performance still thrills car lovers today. 2012 Mercedes-Benz C63 AMG Black Series When the top-of-the-line Mercedes coupe is not enough, you get the AMG. If you find the AMG lacking, then it’s time for the Black Series. All the AMG tech, plus the 6.2-liter V-8 with 510 horsepower motor from the SLS AMG supercar, as well as handling and aerodynamics to make it pliable. Providing stability for all that power is a wider track in both the front and rear. For Merc lovers, it simply does not get any better than this. 2007 Alfa Romeo 8C Competizione From every possible angle, the 8C Competizione is a steel-and-carbon-fiber supermodel of the highest order. You might be surprised that it wasn’t designed by one of the famous Italian coachbuilders — it was designed in-house at Alfa Romeo’s own design center. As with anything, pure looks alone only prevail in pictures and magazines, so the Competizione remains true to its heritage in performance as well. Under the shapely hood, you will find a 450 horsepower V8 designed in cooperation with Maserati. This head-turner is ready to run with the best of them.
