The photo may be mirror imaged. Cool idea, good for farmers as they always drive too slow on the highway anyway.
The site says: "The car is a real 4WD with four motors, one for each wheel. The electricity is stored in the floor in 12 lead-acid batteries that store 48 V and 240 Amperes each." An "ampere" is a unit of electric current, specifically the amount of electric charge flowing through a circuit in one second. So that sentence is meaningless. What would have been useful is the kilowatt-hours of the battery. It shows (to me at least) that the author didn't know what he/she was talking about.
