2011 Mustang Shelby GT500: More Horsepower Than Porsche 911 Turbo S

Porsche 911 and Mustang

Ford and Porsche aren’t usually compared in car blogs or performance tests. Nor do I know of anyone who has ever been in the market for a 911 but ended up buying a Mustang instead.

Still, though, both companies are coming off a year of updating their top-of-the-line thoroughbreds and getting ready for 2011 by updating them again.

On the Ford side, we’ve got the 2011 Mustang Shelby GT500. From Porsche, we have the 2011 911 Turbo S. How can we possibly compare a $50,000 car to a $160,000 car?

Read on to find out.

Okay, the truth is, there is no comparison. Porsche offers an ideal mix of power, performance, and driving dynamics that no other carmaker can touch. The fact that the GT500 has 20 more horses (550 to 530) than the 911 Turbo S is far overshadowed by the Porsche’s 516 lb-ft of torque and a seven-speed dual-clutch PDK transmission. If all you’re doing is driving in straight lines, the GT500 might be a great choice, but even then it won’t stand a chance against the Porsche’s 0-62 mph time of 3.3 seconds.

Plus, the 911 Turbo S has been rated at 26.8 mpg combined, making it one of the most fuel efficient sports cars available.

Not to say the GT500 isn’t capable, it’s just obviously not in the same class as the 911 Turbo S. But it is still pretty sweet, especially considering how little coin it costs (comparatively, of course).

The GT500 will still be powered by a 5.4-liter supercharged and intercooled V8 linked to a six-speed manual transmission. The engine will have an aluminum block, though, cutting weight up front by about a hundred pounds. With those 550 ponies pulling less weight, expect 0-60 times in the low-4-second range and fuel economy of 15 city, 23 highway mpg.

The GT500 can also be had with a Performance Pack, which gives the car stiffer springs and massive 20-inch wheels and tires.

For the money, the new GT500 should be more exciting than ever, but any real driving enthusiast would rather come home in a 911 Turbo S.

Not that anyone would ever compare the two.

Would you rather have a Mustang Shelby GT500 or a Camaro SS? How about a Porsche 911 Turbo or a Jaguar XKR?

  1. I just bought a new 2012 GT over a used 2003 911. It wasn’t an easy call, but Ford really made an incredible car and I just couldn’t stomach the possibility of high repairs bills on the 911. Would I take a new Shelby over a 4 year old 911? Maybe. It’s a problem I look forward to having in a few years. :)

  2. First, I wanna say I to never heard of a pony car making someone sick on a long trip. I drive long trips of 9hr often in my covette (97)and my 04 cobra is just as good on the long trips. personally for the less fortunate money wise like myself the mustang is a better buy if you’re lookin for more bang for your buck since the porsche is almost twice as expensive. With a few simple mods,like beefing up the tires on the shelby can cut down that 1 sec time 0-62 difference

  3. Really depends if you have to ever make any turns. I had not heard that driving a pony car made people sick on long trips. Any idea what causes that, Talha? Maybe its the floormats.

  4. I am totally agree with Bryce….._Porsche have more better control and drive as compare to mustang Gt….& its also better in loolkz as compare to mustang….& camaro also a gud car but it is also a muscle car too….& on a long drive muscle car make person sick

  5. Camaro at least its a new car Mustangs getting old now it still has 1950s suspension and its been beaten with the ugly stick tooo long.

  6. well ^I agree with you,, I’ll place my money to mustang gt rather than the camaro.. and that 911 turbo. muscle cars does represent Power, Muscle and authority.

  7. I’d take the Shelby over the Camaro and the Porsche over the Jaguar easily – I think they’re way better cars, looks-wise. But I need a car I can fit four people and plenty of stuff into, so I wouldn’t buy either one.
