Our friends at sister site Overdrive are covering the big Mid-America Trucking Show in Louisville, Kentucky this week and grabbed a bunch of photos of the Western Star 4900X. This is the truck that is starring as Optimus Prime in this summer’s next installment of the Transformers movie series. The custom truck was unveiled last May but this is our first peek inside.

In the previous Transformers movie, Dark of the Moon, Optimus Prime was played by a Peterbilt Model 379.
