After two years of pure speculation, the Blue Oval released official power figures, top speed, and some lap times
In production spec, the 3.5-liter twin-turbocharged V-6 produces 647 hp and 550 lb-ft of torque. 216 mph
Ford set up a 3 way clocked competition, if that one sided bias can be at all honest, and said that their GT lapped the Calabogie Motorsports Park in Canada, with a fastest lap of 2:09.8, besting a McLaren 675LT by 1.08-second, and a Ferrari 458 Speciale by 3.1 seconds.
Now, I'm not a McLaren and Ferrari expert, hell, I'm not even someone who is likely to ever drive any of these 3... so I don't know if those are the right models to compete with the Ford, or if Ford is making hay with out any independant unbiased Stig to give each the same track effort.
That was the beauty of Top Gear... the cars weren't being driven on the track by someone who would soft show it to get better results for their favorite manufacturer. That leaderboard was about as honest as you'll ever see. The rainy track times did throw things off a bit, but, reality bites, and we can only care so much about the stats of cars we aren't shopping for anyway.
