The newer engine is the same one used in the A,class mercedes
comes in two power outputs 130 bhp and 160 bhp
it dosnt suffer the 1.2 engines well documented timing chain and excessive oil consumption issues
i found mpg on the 130 bhp model to be about the same as my 1.2 qasqaui when i had one for a week as a courtesy vehicle , also the engine is not as smooth as the 1.2 unit and seems to have flat spots , occasional hesitancy whilst driving at lower speeds
