Land Rover's first overseas sale for the 1948 original was to the Swiss Red Cross. Says Edwards: "Will the Red Cross be interested in buying a Range Rover? I don't think so, but I do believe we need to make sure the DC100 is relevant to them."
Pricing the DC100 aggressively could also deliver an extra opportunity for Land Rover.
"The SUV market is growing rapidly, and there is a whole segment of cars in the under 20,000-pound segment that we don't touch. This has got to be an opportunity for us."
Design director Gerry McGovern says: "At its core, the DC100 must be about capability, but cars like the Range Rover Evoque prove that design can also lead. The design must be in harmony with function.
"This isn't a production-ready concept but the beginning of a four-year journey to design a relevant Defender for the 21st century. Replacing the iconic Defender is one of the biggest challenges in the automotive design world - it is a car that inspires people worldwide."
Trademark Defender styling cues such as the door mirrors and floating roof will be allied with off-road extras like a winch, sump guards and heavy-duty tow hooks.
Headlights inspired by the Range Rover Evoque add a dash of upmarket style, as do the raised bonnet line and aggressive alloys. In profile, the block-like shape is combined with sharp creases in the body. Angular glass all-round creates a rugged, wedge-like shape. Under the skin, the DC100 is expected to feature an updated version of the Discovery 4 platform.
Power is likely to come from a range of new four-cylinder petrol and diesel engines, all developed at Land Rover.
No details on interior design have been disclosed, but the latest satellite navigation and communication systems are expected to feature. This will be a world apart from the agricultural design of the existing model.
Edwards says the company is "determined that the new Defender will be true to its heritage, while meeting the requirements of a changing global market. "It's going to be an exciting journey."
