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.
The top-level Sport is powered by a supercharged 390 PS (287 kW/410 hp) 4.2 L AJ-V8, making it the second most powerful vehicle in the company's history except for the larger Range Rover Vogue SE supercharged (450 bhp (340 kW), 420 lb·ft (569 N·m)). A normally-aspirated 4.4 Ltr version is available with 300 PS (220 kW/295 hp). Due to lack of popularity the normally aspirated V8 was dropped from the UK market in 2007, leaving the supercharged model as the sole Petrol model on sale, which has a top speed standing at an electronically limited 130 mph (209 km/h).
