Motor Efficiency

Motor efficiency refers to the ability of an engine to convert the chemical energy contained in the fuel, and heat energy released by combustion, into mechanical motion.

The highest efficiency is being achieved at present by modern diesel direct injection engines, such as those making up the entire SEAT range, with an efficiency of around 45 per cent.
