The Land Rover Defender hasn't been available to the U.S. market since 1997, when the U.S. Department of Transportation passed legislation that required all vehicles to be equipped with air bags for both front-seat passengers. With similar regulations looming for Europe, Land Rover is preparing to overhaul its most utilitarian of utility vehicles, and the DC100 Concept, which debuted on Wednesday at the LA Auto Show, is seen as a possible successor candidate for the iconic Defender model. Both the DC100 Concept and its topless counterpart, the DC100 Sport, feature the same oversized grille and round head lamps as the Defender, along with a 100-inch wheelbase (DC is short for Defender Concept, naturally), 8-speed automatic transmission and permanent four-wheel drive. And like its sporty sister, the DC100 will feature the same high tech systems in the form of intelligent terrain response, as well as Wade Aid, which uses sonar to measure water depth during river crossings. Public reaction has been overwhelmingly positive for the vehicle since it was first introduced during the Frankfurt Motor Show in September, so it's likely fans are hoping the DC100 Concept officially claims the Defender title when Land Rover begins production around 2015.
