Google Ads has introduced a new body style attribute specifically for Vehicle ads. This attribute describes the shape and size of a vehicle, enhancing the level of detail advertisers can provide.
The attribute is optional for all vehicle ads, allowing for a range of values including atv_sport, city_car, convertible, and suv, among others.

Providing an accurate body style can improve ad performance by ensuring the correct representation of vehicles in ads.
