We recently had the chance to finally hear what the Mustang EcoBoost's engine sounds like, and now we know what it looks like. Apparently a test mule showed up at a local dealership and naturally an employee snapped a photo under the hood.

The person driving it said he was averaging 31 mpg on the highway with the air conditioning running.

According to the employee that saw the engine, "baby turbo on it, big turbo should easily over 400hp."

Hear that? Baby turbo. How cute.
