Ford says that the 2011 Mustang GT makes 412 horsepower and 390 pound-feet of torque, thanks to its new, advanced 5.0-liter V8. Well, Ford may just be full of crap. Autojournos have descended upon California this week to to kick the snot out of the 2011 Mustangs at the Blue Oval's invitation, and Inside Line took one of the new 5.0 GT models and strapped it to a Dynojet to see what the real numbers were. Thankfully, they do not disappoint.
It's like this: after seven pulls, Inside Line's tester reliably belted out 395 horsepower at 6,600 RPM and 365 pound-feet of torque at 4,350 rpm. That's at the wheel, natch, and since IL estimates the 'Stang sees only an 11% to 13% driveline loss thanks to its stick axle, the car is likely making somewhere between 438 and 446 horsepower at the crank – far more than the advertised 412.
This should come as no surprise to anyone, especially Inside Line. After all, last year they did the same thing with a 2010 GT500 only to learn that - surprise! - it was underrated. (Their tester put down 511 horsepower at the wheel. The guys figured the number at the crank to be around 570 horses, not the 540 advertised).
Is it possible that the 2011 Ford Mustang GT media launch testers are juiced? Sure it is, but we think it's unlikely. Reason number one is that Ford would be exposed the moment customer cars started getting delivered and dynoed, which would then look really foolish. Reason number two is the 1999 SVT Cobra. Upon its release, that particular car became infamous for not making its advertised 320 horsepower. While Ford eventually made things right via a recall, the incident was clearly embarrassing and likely left Dearborn with a "never again" mentality that sticks to this day. Hence, we're inclined to think Inside Line's numbers are no fluke. The 2011 Ford Mustang GT, with its new engine, is designed to punch the Chevrolet Camaro in the teeth and make it taste blood. By underrating the 5.0, Ford's just, you know, making sure.
Stay tuned for our man Lieberman's first drive impressions next week. In the meantime, follow the jump for video of one of Inside Line's dyno pulls and visit them to watch a few more and read their full analysis. Thanks to everyone for the tips!
