BYD Outsells Tesla Globally. AI Still Recommends Tesla 3x More.
BYD sold more electric vehicles than Tesla in 2025.
Not a little more. Globally, they outsold Tesla to become the #1 EV brand on the planet.
So we ran an experiment: ask 7 major AI models the same question — "Which EV brand makes the best cars in 2026?" — and see who they recommend.
The results were uncomfortable to look at.
What the Data Says
Over two days, we tracked AI Attention Scores (AAS) for 7 EV brands across GPT-4o, Claude, Gemini, Perplexity, and others. AAS measures how prominently a brand appears in AI-generated answers — not just whether it's mentioned, but where and how often.
Here's what we found:
Tesla: AAS 90.18 — mentioned by all 7 models. Every single one.
Rivian: AAS 57.49 — also mentioned by 7/7 models, and jumped from 29 to 57 in a single day after a news cycle. (That volatility alone is a story.)
BYD: AAS 30.85 — mentioned by only 4 of 7 models.
Let that sink in. The company that actually sells more EVs was ignored by three out of seven AI systems when asked who makes the best EVs.
Lucid Motors scored 22.54. NIO got 17.68, mentioned by just 2 models. Xpeng came in at 16.83 — also 2 models.
Tesla's score is nearly 3x BYD's. It's not a rounding error. It's a structural gap.
Why This Happens
AI models are trained on text from the internet. And the internet — at least the English-language internet — talks about Tesla constantly.
Elon Musk generates headlines. Tesla's software updates get Reddit threads. Every Autopilot incident gets covered by 40 tech outlets. The brand has had years of English-language narrative building around it.
BYD? Their coverage skews heavily toward Chinese-language media. Their international expansion is real, but their content footprint in English is thin compared to their market footprint in reality.
So when an AI model synthesizes "which EV brand makes the best cars," it's not looking at sales data. It's pattern-matching against the text it was trained on. And that text has a Western bias baked in.
This isn't a conspiracy. It's a training data problem. But the effect is the same: non-US brands get systematically underrepresented in AI recommendations, regardless of their actual market position.
The Rivian Whiplash
One finding that surprised us: Rivian's score doubled in 24 hours — from 29 to 57.
That's the flip side of the same coin. English-language AI models are extremely reactive to English-language news. A single product announcement or media cycle can swing a brand's AI visibility dramatically.
For a brand like Rivian, that's an opportunity. For BYD, it's a reminder that AI visibility isn't just about what you do — it's about whether the right media ecosystem is covering it in the right language.
What This Means If You're Not a US Brand
AI recommendations are becoming a new form of search. When someone asks ChatGPT what car to buy, what software to use, what hotel to book — the answer shapes purchase consideration in ways traditional SEO never quite did.
If your brand has strong market performance but weak English-language content coverage, you're invisible in AI answers.
We tracked this using AIAttention.ai, which monitors how brands appear across AI-generated responses over time. The pattern we saw with EVs shows up across industries: companies doing real business in the physical world but losing the AI recommendation layer to louder, English-first competitors.
Hyundai and Kia appeared as top competitors in every single brand's results — despite not being in our tracked set. That's the organic AI footprint of a brand that's done serious English-language content work over the years.
BYD is outselling them in actual cars. But in AI-world, they barely register.
The Uncomfortable Question
If AI models are becoming the new product discovery layer — and the evidence increasingly suggests they are — then a brand's AI visibility score may matter as much as their market share.
Tesla isn't winning in AI because they make better cars. They're winning because they've dominated the English-language narrative for a decade.
That's fixable. But first, you have to know it's happening.
We're running more experiments like this across other categories. What industry do you think has the starkest gap between AI recommendations and market reality?
