UK Automotive AI Readability 2026
As of 1 October 2026, the median UK automotive site scored 40 out of 100 on the Crane Index™, the measure of how readably a site presents itself to AI engines. Across the 102 sites a machine could read, scores ran from 20 to 77, a 57-point gap between the strongest and the weakest.
What this measures. The score reads how readably a site presents itself to AI engines: entity markup, structured data and machine resolvability. It is not a measure of design, brand or quality. A site can look excellent to a person and still be hard for a machine to read, and a low score is a readability finding, never a judgement on the business.
The field in 2026
The field was led by Vertu Motors at 77, with Perodua next at 76. 4 sites cleared 70 out of 100, and 48 scored below 40.
At the foot of the field sat Kenworth at 20, McLaren Automotive at 21, Lynk & Co at 21. Each is a site a machine struggled to read, not a business doing anything other than well at what it does.
The full 2026 ranking
Composite out of 100, with the three reads behind it: AI Search Readiness (retrieval), Agent Readiness (execution) and Brand Representation.
