Spotted at the Ford dealership on Memorial Drive in Thunder Bay, On.
From the Auto Editors of Consumer Guide:
The 2007 Ford Shelby GT500
If classic Shelby Mustangs were liberally dosed with Vitamin HP, the '07 Shelby GT500 was a full-blown steroid case. Lurking within was a supercharged 5.4-liter twincam V-8, basically the 550-bhp Ford GT unit with a less-expensive Roots-type blower and milder tuning.
Milder? Not really. Rated horsepower was a thundering 500, torque a stump-pulling 480 pound-feet. This muscle was too much for any automatic on the Ford shelf, so the only transmission was a heavy-duty six-speed manual, familiar from recent Cobras and the race-winning FR500C Mustangs developed by Ford Racing. Thrust control also dictated a beefed-up suspension, big Brembo disc brakes with pizza-size 14-inch four-caliper rotors up front, and sticky high-performance tires sized at 255/45ZR18 up front and a massive 285/40ZR18 out back.
You can get more info from Ford's official site.
