5.8 Liter 2013 Shelby GT-500 Confirmed

While rumor has persisted in the past year about more power for the 2013 Ford Shelby GT-500, the new UAW contract hammered out last week confirms it. Reports have been long out there that the 2013 GT-500 would get an increased displacement and 600+ horsepower.

The contract spells out more investment and work for the Romeo, MI engine plant to build a “5.8 liter supercharged V8”. There is only one place for such an engine and that’s the Shelby GT-500. A larger version of the current 5.4 liter engine is widely considered, as opposed to a punched out version of the new 5.0 Coyote V8. We won’t know for sure until Ford pulls the veil.

With the new Camaro ZL1 making 570hp, most believe that the new 5.8 liter GT-500 will pack 600hp at least, if not well more. Many reports also speculate that the new engine will see a TVS2300 based supercharger, also an Eaton design but more efficient than the M112 supercharger on the current models.

Spy photos show that the 2013 Shelby GT-500 will be getting a significant refresh in the way of new fascias, headlights and tail lights. Several camouflaged test cars have been seen around Dearborn this summer showing body color lower cladding and dual twin exhaust tips. See post #2 below....

We expect Ford to unveil the 2013 Mustang next month at the Los Angeles Auto Show and the 2013 GT-500 at Detroit if history is any guide. We will be on the floor at both shows to bring you the news when it happens.

With all the talk about the next-generation 2015 Mustang its been easy to overlook what’s right in front of us. Ford is readying a mild refresh for the 2013 Mustang set to make its debut later this year. The mid-cycle changes are directed at keeping the Mustang fresh against the Camaro but also to bridge the styling gap between it and the 2015 model.

Recently caught by in Dearborn, MI by forum member Stangpilot007 at TheMustangSource, Ford is now in final testing of the 2013 Mustang. Mustang will be getting revised front and rear fascias to give a cleaner and more aggressive appearance. Mustang GT is said to get a more Shelbyesque grille and fascia treatment to clean up the complex design of the current lower fascia.

As seen in the photos, body colored lower cladding will answer the critics who say the black ABS plastic under belly of the current 2010-2012 models looks cheap. The look will certainly raise the rent on style and will give a fresh overall perspective to the car’s silhouette.

As seen in the photos, rear exhaust openings at least for GT-500 appear to be elongated for double-barrel tips. A new rear tail light panel that spans the rear flank has been reported and new sleeker headlamps are also rumored. The GT-500 at least may see a new hood design as well.

Powertrains for the Mustang V6 and Mustang 5.0 GT are expected to be largely carry-over. Some news outlets believe there might be a slight horsepower bump for the 5.0 liter V8 attributed to software tweaks. The 6-speed manual and automatic transmissions are expected to carry-over as well.

The big news in powertrains is expected with the Shelby GT-500. The rumblings and spy photos this season have pointed to a GT-500 that packs over 600hp. What that power comes from has been rumored to be a larger displacement version of the existing 5.4 liter supercharged engine.

Reports have hinted at 5.8 liters or more from the engine that first made duty in the Ford GT supercar. A larger displacement supercharger is likely as well. While some media outlets have speculated about a twin-turbo GT-500, those who have heard the engineering mules say supercharger.

The 2013 Mustang is expected to debut in Los Angeles at the auto show in November. If history is any guide, Ford will follow up with the 2013 Shelby GT-500 at the Detroit show in January. Full photos and specifications will be out just ahead of both shows. In any case we will be on the floor of both shows to bring photos and video of both.

There is a great article in MMFF this month about the 2013 GT-500. Interesting thing is it will run 15psi from the Factory and turn 7000rpm..(that is 6psi more than the current models and almost 800 more rpm..!!!)

I wonder how much an aftermarket there is going to be for this car since it comes from the Factory with 15psi, a cold air intake and a pretty aggressive tune from what I read.

I guess there will be exhaust upgrades and some people that will turn the blower faster, but how much more than 15psi can you run..I guess we will find out…

eh, you can push 20+ psi on the little Eaton m112 that came on the terminators...i am sure you'll be able to push the bigger TVS blowers much harder

the question is how much can the rotating assembly take

MSRP for the 2013 Model and options are up on the Ford site already.

The 2013s are only 5k more than the 2012 models..not bad for another 100 horse and 100 ft/lbs of torque as well as some other upgrades..
