2013 Ford Mustang Shelby GT500 spy shots
The UAW and Ford reached a contract agreement today that secures 12,000 new jobs in the U.S. by 2015, brings back into the U.S. previously outsourced work, and guarantees $16 billion in investments and upgrades to U.S.-based manufacturing. It also contains a small nugget about the upcoming 2013 Shelby Mustang GT500: a 5.8-liter supercharged engine.
According to the contract documents as scoured by MustangsDaily
(and confirmed by us
[PDF link]), part of the deal involves an upgrade at the Romeo Engine Plant to manufacture a new 5.8-liter supercharged V-8 engine that will replace the current 5.4-liter supercharged unit. The current GT500 uses the 5.4-liter aluminum-block engine.
The obvious implication is that the next GT500, which is already expected to grow in power, potentially up to 600 horsepower
, will use the 5.8-liter supercharged V-8. A 400-cc increase in displacement could be enough to get the 50-plus-horsepower gains expected.
Previous reports have also hinted at precisely this upgrade, but the finding in the UAW contract documents (full contract in PDF form here
) firms up the case for the larger V-8.
