G Series fuel savings are achieved by reducing power between 0.15 to 15 percent during all phases of operation.
This truck has a 23% increase in altitude capability, allowing it to climb to just short of 3000 meters or close to 10,000 feet without affecting performance.
The parking brake is applied on the rear brakes and can hold the machine, with rated load, on a 15 percent slope.
G Series is backed by comprehensive validation and over 25,000 hours working for customers prior to production.
With improved designs that impact braking, traction control and egress, G Series is setting new standards of safety in this size class of truck.
The 770G frame is purpose built for its weight class. This design philosophy provides the best possible load capacity, tire life, and handling
