Engine options include the same 542bhp 5.0-litre supercharged V8 which appears in the Range Rover Sport SVR, although Land Rover says it has retuned the unit for comfort and refinement rather than outright performance. Other powertrain options include the SDV8 and SDV6 Hybrid options, which already feature on the Range Rover.
Top-spec V8 versions of the SVAutobiography also get quad exhaust tips at the rear. It sits on 22in alloy wheels, which are described by Land Rover as being "very expensive" and having "a jewel-like quality."
Speaking ahead of the car’s unveiling, SVO boss John Edwards said the SVAutobiography “takes the Range Rover to another level of comfort, craftsmanship and refinement”.
Land Rover design director Gerry McGovern added: “With the SVAutobiography, we have taken the opportunity to optimise the Range Rover’s luxury execution and precision while delivering beautiful detailing that considerably enhances the customer’s experience of our flagship vehicle.
"Inside, it's all about luxury," said McGovern. "We've used the most expensive materials and finishes, the kind you can only get on a Range Rover. We've also paid far more attention to the rear. You're in first class in the rear, not economy. There is more comfort, softer materials, more appointments. It's an office or dining rooms on wheels.
"We've taken the best and made it better," he said. "It's very expensive."
The launch of the Range Rover SVAutobiography means Land Rover is well placed to tackle the onslaught of super-luxury SUVs planned by Rolls-Royce, Bentley and Mercedes-Benz. Mercedes has already hinted that a luxurious Mercedes-Maybach SUV, likely to be based on the GLS, forms part of its future product plans. Bentley and Rolls-Royce, meanwhile, will have their own SUVs on sale in 2016 and 2017 respectively.
The SVAutobiography is also the first luxury vehicle to be created by the Special Operations division, with previous offerings being related more to performance. It is known that JLR eventually wants its division to cover three areas: performance, luxury and all-terrain vehicles.
"You hear 'icon' used a lot and it's ridiculous - you have to earn your mettle, creating values you execute consistently," said McGovern. "Range Rover has now reached a point after 45 years where it can be called an icon. It's peerless, and there's nothing else like it."
Land Rover has also announced that the MY16 Range Rover line-up will go on sale this summer, with prices starting at £74,950. The updated SUV range comes with more efficient powertrain options - with the Hybrid emitting less CO2 and the SDV8 now returning 33.6mpg with CO2 emissions of 219g/km.
SDV8 models also now get Land Rover’s All Terrain Progress Control system, while all modes come with an upgraded camera system and a new gesture tailgate, which provides hands-free access to the boot, as well as automatic height adjustment. JLR’s InControl system has also been updated.
