Next month Land Rover is set to take the covers off its all-new, fourth-generation Range Rover, the vehicle that will eventually spawn a new iteration of the potent Range Rover Sport. Today, we have an exclusive spy video of a prototype for the new Range Rover Sport, taken as it laps up the Nürburgring and travels on some of the race track’s surrounding roads.

Set to be introduced for the 2014 model year, the new Range Rover Sport looks as though it will more closely resemble the aggressive lines of the smaller Range Rover Evoque rather than the somewhat simple looking Range Rover. In particular, the prototype seen here features a much more sharply-angled roof and narrow, slit-like lights front and rear.

The vehicle’s platform will be shared with the regular Range Rover and is expected to be a lightweight, rivet-bonded aluminum design based on a modified version of the platform underpinning the Jaguar XJ. By combining this with some advanced composite materials, Land Rover engineers are likely to have reduced the vehicle's weight dramatically, ensuring quicker acceleration, improved handling and lower fuel consumption.

The current model’s engine lineup should carry over, though with significant revisions to make them more environmentally friendly. One possibility is the adoption of an eight-speed automatic instead of the current six-speeder, an option that is already offered on some Range Rover Sport models sold overseas.

The new HSE should get a 5.0-liter V-8, good for 375 horsepower and 375 pound-feet of torque, while the range-topping Supercharged variant will likely get a force-fed version of the same V-8 good for 510 Horsepower and 461 pound feet of torque. Other markets will get a turbodiesel V-6 option and potentially a new supercharged gasoline V-6 as well.

The interior will feature a much more premium look and feel, complete with carbon fiber themed packages or traditional polished wood for the trim. A large display screen in the center stack, digital instrument cluster and an available Harmon Kardon sound system should also feature.

Stay tuned for updates as development progresses, and look for the 2014 Land Rover Range Rover Sport to hit showrooms before the end of next year.
