Land Rover has unveiled the Range Rover Sport SVR prototype, ahead of its debut at the Goodwood Festival of Speed.

Designed to be the "fastest and most powerful" Range Rover ever created, the SVR prototype previews the production model that will be launched in 2015. The prototype also marks the launch of the SVR moniker which will be used to distinguish all future high performance models developed by Jaguar Land Rover's Special Operations division.

Unfortunately, the prototype is the same model our spies have snapped on multiple occasions so it doesn't reveal much other than an aggressive front fascia with a mesh grille and larger air intakes. We can also see a new rear bumper with an integrated diffuser which is flanked by a four-tailpipe exhaust system. Last but not least, there's and massive alloy wheels and a high-performance braking system.

Land Rover is declined to release detailed specifications but they confirmed the model has 550 PS (405 kW). This matches up with earlier reports which indicated it would have a supercharged 5.0-liter V8 engine that develops 550 PS (405 kW) and 680 Nm (501 lb-ft) of torque. Since this is 40 PS (29 kW) and 55 Nm (40 lb-ft) more than the Range Rover Sport Supercharged, we can expect the SVR to accelerate from 0-60 mph in less than 5.0 seconds. Regardless of the final numbers, Land Rover says the SVR will "extend the Range Rover Sport's established capabilities as the fastest, most agile and most responsive Land Rover ever built."
