HUMMER, the world's most serious 4x4, stands alone atop the mountain of off-road vehicles. The new General Motors HUMMER H2 is an authentic evolution in a truly incomparale species.
The H2 draws reverently from the current HUMMER H1 production vehicle and its tradition of strength, toughness and 4x4 leadership. The H2 echoes the roots of the HUMMER'S own heritage.
The H2 is a design exercise that modernizes and updates the HUMMER while keeping its best traits intact - the aggressiveness, rawness and toughness that first attracted customers to the vehicle and earned it the status of an American icon. The H2 takes those characteristics and refines them, casting a wider net over the sea of consumers searching for a truck like the HUMMER.
The H2 is a truck built for people with an adventurous spirit who want to do what others can't, in an SUV that can do what other sport utility vehicles can't.
Experience what HUMMER is - the lifestyle, the philosophy, the confident attitude.
