Creating a phone on that level of detail is SIGNIFICANTLY easier than creating this car in this level of detail, especially with all of the dirt/rust/HDRI maps that would have to be made for this.
Everything from the slight bends in the license plate, down to the few blades of grass sticking to the wheels…it’s all TOO realistic, not to mention the newer Mini Cooper sitting next to it and all.
The biggest giveaway that this is a photo is the background photo. If you were to take the car away, what would the subject of this picture be? Nothing. The depth of field is focused exactly on the position of this car, not whatever is going on in the background.
