The German motoring giant has introduced an all-new ten model testosterone range in the form of the Mercedes-Benz Unimog that boast engines as green as they are powerful ranging from 5.1 to 7.7 liters. The ERG-cooled long-stroke engines sport solenoid injectors with ten-hole jets resulting in up to a 90 percent emission reduction. Further features include a redesigned panoramic cab, power hydraulics and synergetic traction drive. Production will begin in September.
