UAW-Ford Contract Reveals 2013 Shelby GT500 To Get 5.8-Liter Supercharged V-8

2013 Ford Mustang Shelby GT500

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 Mustangs Daily (and confirmed by us  [PDF link]), part of the deal involves an upgrade at the Romeo Engine Plantto 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 firms up the case for the larger V-8.This news is taken from motorauthority.com
