Roof Boxes, Roof Tents, Baskets & Cargo Boxes / Tow bar cargo boxes
Rear-mounted cargo boxes, such as the 400 litre Thule Arcos, will add essential luggage capacity to a car. A tow ball attached cargo boxl is in many ways comparable to a roof box but is much easier to load and unload due to its convenient access height.
A rear-mounted cargo box is the optimum luggage carrying solution for EVs and other vehicles, such as those with high fuel consumption, where a roof box is not always totally practical. According to experiments conducted by a well-known Swedish automotive magazine, a rear-mounted cargo storage box can increase the airflow over the vehicle, with little or no negative influence on EV range or fuel efficiency. In many cases, it can even improve the range or reduce fuel consumption.
