Whilst it may seem that magazines are right, because they're doing their job, they can be wrong too. In the real world, the GT500 is an easy low 12 second car, the stock tires are not the best, but there have been much faster times than 13.1 recorded. "The people in magazines generally drive conservatively. They don't powershift, they don't warm up the tires, sometimes they don't turn traction control off, and more often than not they run the cars on regular pavement and not a prepped track. Their numbers are typically not where they should be, which is done for a reason. If all the magazines ran the new Cobra to 12.1 while the average guy who takes his car to the track can't break 13's they are going to end up with quite a few complaints, letters, ect. If they low ball the numbers and people consistently run a tenth of a second faster or so the average driver will think they're the next Evan Smith and be happy and content." - anonymous "Ofcourse it gets beat by the corvette, everything gets beat by the corvette. Even ferrari's" - anonymous Also, the skidpad R&T listed is also very wrong, .87g? Yeah, right. That's what a Mustang GT gets. Muscle Mustangs & Fast Fords - 12.257 @ 117.18mph Motor Trend - 12.7 @ 116mph Car and Driver - 12.9 @ 112mph, .90g "The 500-hp figure was obtained using the latest SAE-certified test protocol, so it’s unlikely that the GT500 isn’t delivering the promised ponies. Maybe we were off that day." Road & Track - 12.9 @ ???mph (I think it's odd their online site posts a dif. time) http://www.roadandtrack.com/article.asp?section_id=2&article_id=3086&page_number=3 Automobile Magazine - 13.1 @ 115mph (Check out the mph compared to the others) .95g Mass Driven - .94g SVTperformance - .94g It's fairly easy to see that the car is simply hard to start, hard to get traction. However, it's still fast as balls. http://www.dragtimes.com/Ford--Mustang-Shelby-GT500-Drag-Racing.html Some drag strip times from real people http://www.dragtimes.com/Chevrolet-Corvette-Timeslip-8295.html Corvette z06 drag time for comparo http://www.dragtimes.com/2006-Chevrolet-Corvette-Dyno-Results-Graphs-8827.html A chart showing the Corvette's drivetrain losses, for comparison purpose "A ballerina's balance is too much to expect of any true muscle car, so there is ample understeer when the Goodyears slide. However, a few laps circulating California Speedway's tight road course revealed a strategy that keeps the Shelby from tripping over its front feet: complete the hard braking with the steering dead straight, turn in gently, then add throttle well before the apex to encourage the rear tires to shoulder their share of the load. Plan B is to hurl the car into the bend, adding full throttle to hang the tail out. That works, but it's neither the tidy nor the quick way around any corner." - Automobile Mag As far as upgradability goes, the GT500 with it's 8.4:1 compression ratio and the supercharger you can rig easily with a larger pulley, 650hp doesn't seem out of reach for very, very little money. As a final note, everyone needs to realize this is a $40,000 Mustang. Ford themselves said "We could have put IRS and made it lighter, but then it wouldn't have been a $40,000 mustang." Or something along those lines, don't remember off hand. If it were a $70,000 GT500 then it would be pitted against the z06, most likely. However, that is not the case. They created a muscle car, not a lightweight track racer.
