Who Ya Gonna Call? Rivian Turns the R1S Into a Ghostbusters Ecto-1

Rivian has officially crossed the streams. For Halloween 2026, the electric automaker teamed up with Sony Pictures to transform its R1S SUV into the Ecto-R1, a modern interpretation of the legendary Ghostbusters ambulance. White wheels, red graphics, oversized No-Ghost logos and a roof loaded with vintage emergency equipment make this one of the better automotive movie tributes we've seen in years. And yes, Bill Murray is involved.

The custom build goes further than a clever wrap. Rivian fitted the Ecto-R1 with restored vintage emergency lights, spotlights, sirens, a radar dish and the kind of wonderfully excessive roof-mounted hardware that made the original 1984 Ecto-1 unforgettable. The company also brought back Murray as Dr. Peter Venkman for a new commercial developed with filmmaker Gil Kenan, who worked on Ghostbusters: Afterlife and Frozen Empire.

The real trick is that ordinary Rivian owners get to participate. A limited-time software update brings Ghostbusters-themed displays, custom lock sounds, exterior light shows, Slimer appearances and a dedicated in-car app to the R1S, R1T and R2. There's even a Mini-Puft arcade game called 'Mallow Mash, plus a Trick or Treat mode that turns the vehicle into a neighborhood ghost-hunting attraction. Most interactive features work while parked, with select visual effects remaining active on the road.

The physical Ecto-R1 isn't headed for dealership inventory, but Rivian is displaying its custom builds at locations across the country, including Miami, New York and Los Angeles. The Halloween software experience runs October 9 through November 2, 2026. It's ridiculous in all the right ways, and a reminder that electric vehicles can have a personality beyond their range figures.
