Quick question about the 2015 model

[70XR7]

There's a nice red 2015 parked outside my work, but I can't tell if it's a 4-banger or the V6. Last year you could tell the difference between the V6 and the 5.0, and those differences still exist with this year's 5.0.. but what are the differences between 2 smaller engine options? Physical, that is.
both have dual exhaust. Pony emblems.
Is it the rims? I don't think the 4-banger has an Ecoboost badge, does it?

The main differences are the packages available.
The V6 emblem has the tribar pony on the back but without the colours. It also lacks the rear diffuser that the EB and GT have.
The v6 has a few parts options but no package options. Unless it was ordered for someone I doubt it's a V6. It's generally treated as a fleet vehicle. There just aren't the upgrades/options available for the V6 and the after market is avoiding it (with a few exceptions).
