Land Rover says its new DC100 concept, set for the upcoming 2011 Frankfurt Auto Show, is a precursor to a new Defender.

The SUV maker indicates a new Defender is on the way--but in the release accompanying these photos, says there's been no plan to market a version of the new off-roader in North America.

The new-generation Defender will be launched by 2015, according to the release.

Chief Land Rover designer Gerry McGovern is stated as saying: "Replacing the iconic Defender is one of the biggest challenges in the automotive design world; it is a car that inspires people worldwide. This isn't a production-ready concept but the beginning of a four-year journey to design a relevant Defender for the 21st century."

No details on the concept's running gear were released, but are set to be announced during the Land Rover press conference in Frankfurt on September 13, 2011.
