Land Rover wants you to know its fifth-generation Discovery SUV is capable – so capable, in fact, that it can flat-tow a semi truck with seven trailers weighing a total of 121 tons a distance of 10 miles. Is this a publicity stunt that’s well beyond what anybody would attempt in their luxury SUV? Of course. But, Land Rover’s point is that the Discovery and its 3.0-liter V-6 turbodiesel Td6 are built to do the extremes. Even with the marketing hype, I can say I’m honestly impressed.
