In order to show off the capability of its diesel-equipped Discovery SUV, and to announce the introduction of the Discovery's 2018 model year, Land Rover hooked it up to the aforementioned 328-foot-long road train and towed it 9.9 miles on a closed section of highway in Australia's Northern Territory.

It should be noted that the Discovery Td6 diesel's standard tow rating is a still-impressive 7,716 pounds with the right setup, and any attempt to do this on your own will probably void the warranty until the end of time. There are better things to do with 443 pound-feet of torque.
