For 2007, G-Class received its first high-intensity discharge headlamps, reversing camera, and tire pressure monitoring system (the latter two are federally mandated safety equipments for the United States). G 500 can be fitted with the sports side exhaust pipes from G 55 AMG for extra cost. The power output for G 55 AMG was increased from 350 kW (469 hp) to 368 kW (493 hp).
