A spy shot has surfaced online that may show an early prototype of Tesla’s upcoming all-electric pickup truck.

A Reddit user posted this single image online, showing a large car transporter in Eastern Ohio carrying a bunch of Tesla Model 3s finished in grey and one painted white. Sitting at the rear of the transporter is a mystery pickup truck covered in a white sheet. The pickup in question may not seem identifiable, yet some eagle-eyed observers suggest that beneath the white sheet is a Roush F-150.

What would a Roush-tuned Ford F-150 be doing on a car transporter filled with Teslas you ask? Well, it is possible that this isn’t actually an F-150 and that Tesla is testing its upcoming pickup truck under the skin of an F-150. Fellow electric car manufacturer Rivian revealed that this is exactly what it has been doing to secretly test the Rivian R1T.

However, it is impossible to know for sure what exactly this pickup truck is doing on a transporter loaded with Tesla Model 3s. The Drive notes that the Transportation Research Center is located just a few hours away from where the truck was spotted and is used as a testing ground for forthcoming vehicles. The National Highway Traffic Safety Administration’s Vehicle Research and Test Center laboratory is also located at the same site.

One aspect of the pickup truck – which would be odd if it did feature an all-electric powertrain – are the dual tailpipes exiting from the side of the pickup’s rear. EV prototypes have been known to feature fake exhausts in the past, but not Tesla test mules. In the end, what makes the vehicle’s presence on the transporter all the more curious is that an old teaser image released of the Tesla pickup suggested that it would be much larger than an F-150.
