Who You Gonna Call? Rivian Transforms EVs into the Ultimate Ecto-R1 for a Blockbuster Halloween Software Update
NEW YORK — Rivian has officially cemented its reputation as the master of automotive seasonal software drops. Building on the success of previous fan-favorite holiday updates—including the nostalgic Knight Rider K.I.T.T. makeover and the Back to the Future time-machine interfaces—the American electric vehicle manufacturer has returned with what is arguably its most ambitious and immersive seasonal transformation yet.
Rolling out globally to owners of the R1S, R1T, and the newer R2 platform, the comprehensive software package (version 2026.36.40 for the R2 and 2026.36.0 for the R1 line) trades the roads of the 1980s for the supernatural streets of New York City. Rivian has partnered with Sony Pictures to turn its entire fleet into modern-day iterations of the iconic Ecto-1, complete with a custom, one-off physical build christened the "Ecto-R1."
To launch the update in true cinematic style, Rivian rolled out the custom Ecto-R1 in Manhattan, complete with a surprise appearance from legendary actor Bill Murray—reprising his iconic role as Dr. Peter Venkman in spirit—who took a passenger-side joyride around the block. Blending cutting-edge EV technology with classic 1980s pop culture, Rivian has delivered a masterclass in experiential automotive marketing.

Chronology: From Concept to Manhattan Streets
The journey to transforming Rivian’s rugged electric adventurers into ghost-hunting vehicles unfolded across months of secret development and high-profile cinematic coordination.
Phase 1: Conceptualization and Hollywood Collaboration
Following the viral success of its previous pop-culture integrations, Rivian’s design and software engineering teams sought a franchise that matched the adventurous, rugged, and slightly irreverent personality of the brand. Collaborating with Sony Pictures, Rivian brought in filmmaker Gil Kenan to ensure the digital interface and physical vehicle designs remained faithful to the cinematic lore established over four decades.
Phase 2: Building the Ecto-R1
While everyday owners would receive the digital update, Rivian’s customization division set to work on building a tangible flagship vehicle. Using a production-spec Rivian R1S, the team applied a custom white wrap, iconic Ghostbusters door decals, and painstakingly recreated the roof-mounted ghost-containment and radar hardware seen on the original Cadillac Miller-Meteor Ecto-1. Vintage-style police and warning strobes were integrated into the rack, alongside specialized rear-compartment gear to ensure authenticity.
Phase 3: The New York City Reveal and Bill Murray’s Joyride
On the eve of the software rollout, a special media and fan event was held in New York City. Passersby who caught a glimpse of what appeared to be a futuristic Ecto-1 looping around Manhattan blocks were met with a delightful reality: Bill Murray himself stepped out to inspect the vehicle. Murray praised the engineering and aesthetic balance of the custom build, subsequently climbing into the passenger seat for a high-profile loop around the city streets.
Phase 4: Global Software Deployment
Simultaneously, the over-the-air (OTA) update began beaming down to tens of thousands of Rivian vehicles worldwide. Owners turned on their ignitions to find their infotainment systems transformed into high-tech paranormal monitoring stations, bringing the cinematic experience directly into consumer driveways.
Supporting Data & Technical Deep Dive
The technical execution of the Ghostbusters update demonstrates Rivian’s mastery of vehicle-as-a-software (VaaS) architecture. Rather than locking the experience behind a single static wallpaper, Rivian utilized the vehicle’s native ambient lighting, external speakers, pneumatic suspensions, and high-resolution displays to create an interactive sensory environment.
The "Trick or Treat" Interface
When activated, the central touchscreen transforms into a weathered, toggle-heavy control panel reminiscent of a Proton Pack or PKE Meter.
- Interactive Elements: Rivian injected subtle humor into the UI. For instance, if a user attempts to toggle a specific radar switch on the screen, an animated ghostly hand playfully reaches out from the UI to flip it back off.
- Ecosystem Integration: The theme is not confined to the central display. It extends seamlessly to the driver’s instrument cluster behind the steering wheel and synchronizes with the official Rivian companion app available on iOS and Android devices.
Lighting and Audio Presets
Owners can cycle through a variety of custom preset modes via the vehicle’s controls:
- Ecto-1: Triggers the classic siren audio alongside flashing emergency light routines.
- Proton Pack: Mimics the winding, high-energy hum of discharging particle throwers.
- Slimer: Features eerie green cabin lighting and playful spectral sound effects.
- Ghost Trap: Coordinates floor-level lighting to simulate trapping an entity beneath the vehicle.
- Peter Venkman / Random: Curates spontaneous combinations of sights and sounds.
Motion Mode and Exterior Showmanship
One of the update’s standout technical features is Motion Mode. When enabled, the vehicle utilizes its external proximity sensors and pedestrian-warning speaker systems to trigger light and sound sequences whenever a passerby walks too close to the parked vehicle.
Furthermore, for those times when the vehicle is parked at a Supercharger or home charging station, occupants can access the integrated arcade game Mallow Mash, challenging players to pop waves of Mini-Puft marshmallow men using touch controls.
Official Responses and Industry Commentary
The collaboration drew high praise not only from tech reviewers and automotive enthusiasts but also from the Hollywood elite involved in the franchise’s legacy.
Bill Murray, known for his selective and often deadpan appraisals, offered glowing remarks after inspecting the custom Ecto-R1 in New York. Describing the vehicle’s design ethos, Murray noted:
"Just technical enough, and just silly enough to be perfect; it’s really perfect."
After experiencing the synchronized light shows and onboard sound effects, Murray simply dubbed it a "cool car," visibly tickled by the commercial spot and the subsequent joyride through Manhattan.
Jacob Krol, US Managing Editor for News at TechRadar, who attended the exclusive New York reveal and went hands-on with the R2 software update, highlighted the depth of Rivian’s execution:
"Rivian has taken something as ordinary as a seasonal software update and turned it into a playful tribute to a beloved franchise, complete with the lights, sounds, and interactive touches that make it feel special. It might even be enough to get a few Ghostbusters super-fans looking at a Rivian in a whole new light."
Implications: The Future of Over-the-Air Automotive Entertainment
Rivian’s continuous string of holiday software drops highlights a broader paradigm shift in the modern automotive industry. Cars are no longer static mechanical assets defined solely by horsepower, towing capacity, and battery range; they are rolling software platforms capable of evolving, entertaining, and emotional storytelling.
1. Strengthening Brand Loyalty and Community Engagement
By transforming routine software patches into cultural events, Rivian cultivates a passionate, highly engaged owner community. Features like the Knight Rider and Ghostbusters updates generate massive organic reach across social media platforms like TikTok, YouTube, and X (formerly Twitter), providing invaluable free marketing that traditional television commercials struggle to replicate.
2. Redefining In-Vehicle User Experiences (UX)
As autonomous driving capabilities advance and charging times necessitate stationary periods, automakers are competing fiercely on digital ecosystems. Rivian’s ability to completely reskin its operating system into an interactive, gamified environment demonstrates the immense flexibility of its proprietary software stack. It proves that utility and whimsy can coexist within a premium electric vehicle.
3. Setting a New Standard for Brand Partnerships
The success of the Ecto-R1 and the accompanying Ghostbusters software suite establishes a high watermark for cross-industry collaborations between Hollywood studios and automotive manufacturers. Moving forward, consumers will increasingly expect automakers to leverage entertainment intellectual properties in creative, software-driven ways.
As the Halloween season peaks, thousands of Rivian owners across the globe are stepping out to their driveways, key fobs in hand, ready to answer the ultimate question: Who you gonna call? With Rivian at the wheel, the answer is already downloaded and ready to go.
