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 many issues of Volume One and Two of the Ongoing IDW Comic Series.


The Ghostbusters had put improvements on Ecto-1 with more technical equipment.[1] 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, and was put on the hood.

Secondary Canon History

IDW Comics

After the "Infestation" event, the Ghostbusters switched from their Ecto-1 look back to Ecto-1a with a few tweaks, such as keeping the classic No Ghost logo. 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. Luckily, a Super Slammer Muon Trap was attached to the roof for the trip. On Peter's cue, Laura opened the trap and the phantom was captured. Once the Ghostbusters returned to New York, Ray Stantz and Winston Zeddemore began maintenance on Ecto-1a. The next year, the New Ghostbusters used Ecto-1a for a little over three months while the Ghostbusters were imprisoned in the Collectors' Limbo. Kylie Griffin drove Ecto-1a to the Parkview Psychiatric Hospital for a consultation that turned into a confrontation with Idulnas and The Collectors. In November, on the night of the Day of the Dead, Ecto-1a's roof was slashed up by a projection of Santa Muerte. Winston was visibly angered by the attack and shot the projection, causing it to split into two.
