Which European EV brand do AI engines actually recommend? EPR has designed a study to measure that directly by testing ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews against a fixed set of buyer prompts and counting which brands each engine names. This page publishes the intended scope and prompt design for that study. Scoring and per-brand results have not yet been completed or published for this category.
What This Index Is Designed to Measure
The European EV Citation Share Index is designed to test which European electric-vehicle brands AI engines name in response to real buyer questions, such as "best European EV" or "cheapest European EV." The study is intended to use EPR's locked Citation Share methodology, the same framework applied in EPR's Stablecoin, Neobanks, and Payments Processors indexes.

Stellantis
This candidate list reflects European market presence and brand recognition, not any prior scoring. Additional brands, including Chinese entrants such as BYD, MG, Nio, XPeng, and Zeekr, are candidates for inclusion once the study runs, since AI engines may treat them differently than European-badged brands on prompts that specify "European EV."

Frequently Asked Questions
Disclosure
Everything-PR and 5W AI Communications share common ownership. Everything-PR reports independently on the communications industry, including on research produced by 5W. Editorial decisions are made by Everything-PR's editorial team.
Has the European EV Citation Share Index been scored yet?
No. This page describes the intended methodology, candidate brand set, and prompt design. EPR has not yet completed or published per-brand scoring for this category.
Why might Stellantis brands be harder for AI engines to cite?
Stellantis sells EVs under five separate brand names rather than one consolidated sub-brand. The study is designed to test whether that fragmentation suppresses citation share relative to sales volume, but this remains a hypothesis until the study runs and results are published with a named sales-data source.
Is Tesla included in this Index?
No. This Index is scoped to brands marketed as European. Tesla manufactures in Germany at Gigafactory Berlin-Brandenburg but is a U.S.-headquartered company and is out of scope for this category-specific study.
When will results be published?
EPR has not yet set a publication date for this category's scoring. This page will be updated, and the update dated, once results are available.
