Auto journalists are still combing through the tentative labor agreement reached by Ford and the UAW last week, looking for juicy tidbits like the news that the 2013 Shelby GT500 will get a 5.8 liter supercharged V8 next year. Most of the news has to do with the factories and what they will build, from new models shifting production locations to all new engines.

In fact, Car & Driver reports in the same agreement that discusses bringing Ford Transit Connect production to American factories, there is also word of a new, small-displacement V6…and C&D thinks it could be another EcoBoost engine destined for a Mustang SVO.

Bill Ford Jr. already let it slip that Ford was working on an SVO Mustang successor (though that name is likely to stay in the past, as SVT replaced SVO nearly 20 years ago). And Ford has said time and again that EcoBoost engines would find their way into pretty much every vehicle in their lineup…and that must include a Mustang, right?

So far most SVO rumors focused on the 2.0-liter four-cylinder EcoBoost engine coming in the new Focus ST. But Car & Driver reports that a new V6 engine with displacement between 2.5 and 3.0 liters, aided by EcoBoost turbos, could slot in well between the 365 horsepower 3.5 liter EcoBoost engine and other, smaller EcoBoost engines. After all, would Mustang owners really want to share an engine with the Ford Focus? Probably not…

Of course, this is all just speculation, and there is no mention of EcoBoost specifically…this could simply be a small-displacement general-use V6 Ford is working on, but we hope it’s more than that.
