Appeared in Ghostbusters II
IDW Comics

The Ecto-1a was an updated version of the Ecto-1 that the Ghostbusters used to travel. This vehicle appears in the film Ghostbusters II and the Ongoing IDW Comic Series.


The Ghostbusters had put improvements on Ecto-1 with more technical equipment. One of the most noticeable upgrades was a digital announcement board running down either side of the vehicle's roof broadcasting Ghostbuster advertisements, specials, and their phone number, JL5-2020 or 555-2020. Also, the logo was updated on the doors and back entrance of the ambulance.

Secondary Canon HistoryEdit

IDW ComicsEdit

After the "Infestation" event, the Ghostbusters switched vehicles back to Ecto-1a. Ecto-1a was taken along by the Ghostbusters on their summer cross country trip across America. It was rear ended when Peter and Laura Parr were attacked by the Phantom Truck Driver. Once the Ghostbusters returned to New York, Ray Stantz and Winston Zeddemore began maintenance on Ecto-1a. The next year, on the night of the Day of the Dead, Ecto-1a's roof was slashed up by a projection of Santa Muerte.


  • Ecto-1a was originally scripted as Ecto-2, and one reference to this remains in the movie. When Dr. Venkman is standing outside of his apartment and the car pulls up, the phrase "Ecto-2" is visible on the license plate. It is parked inside the Firehouse garage bay.
