Do we pay more for highway tolls?

No, because the Faraday is less than 2 meters tall.

Please note: On the highway, towing a trailer may change your vehicle's "class" and therefore increase the toll.

It depends on the overall height of the vehicle (excluding any cargo such as bicycles or roof racks):

Overall height / Toll class / Impact on price

Less than 2 meters / Class 1 / Standard rate (same as for a single car).

Between 2 and 3 meters / Class 2 / Higher rate (approximately 1.5 times the price of a car).

Over 3 meters / Class 3 or 4 / Heavy-duty vehicle rate (much more expensive).

Most standard luggage trailers are less than 2 meters high and therefore don’t cost a penny more at the toll booth.

On the other hand, a large trailer or a tall boat trailer will put you in Class 2.
