Automotive model feeds, known in beta as Vehicle Top Ads, are now available for vehicle manufacturers (OEMs) in Google Ads. This new format allows showcasing vehicle lineups with visuals and details directly in Google Search results.
Participating advertisers can display dynamic images, pricing, and features of vehicles alongside standard text ads.
To join this beta, the requirements include OEM brand status, active Search campaigns, and a valid automotive model feed, available in regions like the US, Canada, Australia, and UK.

Google automatically matches the provided model feed data with relevant search queries and text ads.
Advertisers interested in removing these ads can do so by deleting the feed in the Business Data section of their Google Ads account.
