The new Range Rover Sport Autobiography limited edition is the top model into the Land Rover's 2010 line-up. The introduction is going to be held in Frankfurt at the IAA International Motor Show, which starts this morning.

The ultimate Autobiography limited edition Sport is equipped with supercharged 3.6 litre TDV8, new grille design, vents and 20" diamond turned finish alloy wheels. The interior is also high-end finished in duo-tone premium leather.

The new Land Rover line-up benefits from many exciting developments across the range, including more powerful new engines offering greater fuel efficiency, dynamic upgrades and striking exterior and interior design improvements for the Range Rover, Range Rover Sport and Discovery 4.

For 2010, Land Rover's flagship Range Rover offers a powerful new 5.0 litre supercharged LR-V8 engine (alongside the popular TDV8), revolutionary interior technologies and enhanced driving dynamics. Now, a series of further refinements are available as options across the range, with the focus on enhanced luxury for rear seat passengers.

Land Rover is introducing electronically-controlled reclining rear seats, which will be particularly valued by chauffeur-driven customers. Controlled by the rear passengers and available with heated and cooled functionality, four-way adjustable lumbar support and airline-style winged head restraints. Rear seat passengers can also enjoy significantly increased leg room by remotely moving the front passenger seat to its forward-most position (when the front passenger seat is unoccupied). The addition of laminated rear-door privacy glass significantly reduces interior noise levels too.

The peerless luxury and exclusivity provided by the Range Rover is given a further boost by the addition of four sumptuous new interior colour combinations on the Autobiography series, and the availability of the world-class Logic 7 1200W Harman Kardon High Dynamics audio system, with 15 independent channels driving 19 premium quality speakers.
