The Range Rover Sport made the Premier Automotive Group the target of a protest by Greenpeace in 2005. The protesters infiltrated an assembly facility and temporarily delayed production of the vehicle. Greenpeace quoted issue with contributions to greenhouse gas emissions, and by extension, global warming, that would result from the vehicle's inefficient combustion of hydrocarbons. The United States Environmental Protection Agency estimates for the non-supercharged car are 14mpg-US (17L/100km; 17mpg-imp) (combined). Although, it must be noted that for this test the EPA used their newly calibrated system for 2008 and on.
The Range Rover Sport made its first appearance late in 2004, as a concept vehicle called Range Stormer. This was a bright orange, low-slung, 3-door, that hinted very heavily at the styling of the new model. When the production model was released, it had morphed into a five-door, was not much shorter than the standard Range Rover, and its styling was much less radical, although still identifiable with the concept model. This disappointed many people, though it is still selling well. It is questioned, however, whether this model will actually add sales, or simply cannibalise the Range Rover's sales.
Contrary to the image portrayed by its "sport" tag and styling, the vehicle employs the off-road systems of the Discovery 3.
Its off-road capabilities were used on the British motoring show Top Gear, when Jeremy Clarkson had a skirmish of manoeuvrability in one with a Challenger 2 tank on Salisbury Plain
