Shelby is going to have to make a new motor soon. The GT is up 97-hp from last year, but the Shelby is up just 10-hp from last year! It may seem ridiculous, but 550-hp may not cut it for the price.
With the GT now making 412-hp, the Shelby should be 684-hp. They’re usually about 66% more than the GT, and they better be for the price premium!

At this rate, the 2015 Shelby GT500 will have negative -15 horsepower. To be exact, going off of the difference from 2010 to 2011 alone, the 2015 Shelby GT500 will be 592-hp, while the regular Mustang GT will be 1206-hp.
I don’t mind horsepower, or torque for that matter. And I certainly don’t want muscle cars to go away. They’re better for the environment. Hybrids have huge batteries that are hazards after 10 years. But I digress.
If this madness continues, we will have 1000-hp Mustangs in the near future. Now I don’t actually think we’ll see that. We just oo’d and aah’d about a 300-hp GT in 2005, but the Mustang GT made 271-hp back in 1965 when it debuted!
I suppose everything runs in cycles, spinning in circles like the records we used to listen to. Back when TV wasn’t reality, and I liked it. Back when you had to get out of your car to get a coffee. Back when clothes were ugly and everyone was hairy… and a hippie. OK never mind, I like the present better.
