Great link, I wish it was in English rather than Japanese.
From what I could figure out from the Ecology page the engine comes in two different versions1.33 L and 1.0 L.One may be diesel and the other gasoline.See copy from spec page below.
The lower line is what I believe to be the 1.33 L version, The two differnet mileage columns are MT and CVT respectively. The mileage figures of 21.2 and 20.8 km/L convert to 50.65 MPG for the Manual Transmission (MT) and the 49.6 MPG for the Automatic CVT.
The first listed engine 1.0 L gets 56 MPG with MT.
