Diesel Comparison of NEw volvo EC210b prime vs Old Hitachi EX200-2

i have recently measured the diesel consumption of my new EC210b prime volvo excavator..the consumption is 13-14liters per hour in heavy digging....



but in comparison



my unit of hitachi EX200-2(an old model unit of excavator) consumed an awesome 8-9liters per hour in continous heavy digging..





i dont know whats the explanation in this..but i definitely sure that this is not a phenomena:confused:but rather an engine performance:beatsme...



deutz vs isuzu bd series..
