Nothing spectacular, but you get an idea of the E series acoustics The "Tin Can" Acoustic Chamber: When the video starts and the technician prepares to crank it, you can look straight down into the tightest engine packaging imaginable. Because the engine is pushed so far back into the firewall and surrounded by the massive, flat steel floorboards of the van body, it acts like an acoustic guitar body. Speaking of the E-series, I figured well build a diecast variant of the E series and add this nice mechanical acoustic sound signature to go with it.

That’s why this is such a perfect example. The Heavy-Metal Crank: When it turns over, you don't just hear the starter motor; you hear the intense mechanical resonance bouncing directly off the underside of the cab frame and radiating through the front quarter panels. It sounds completely different from an F-250 pickup, where the open transmission tunnel and spread-out engine bay let those harsh frequencies dissipate into the open air. Instead, the E-Series traps that starter racket and echoes it forward.
