A significant amount of energy (fuel) use in motor vehicles is consumed by components that are not covered under US or EU efficiency testing programmes, i.e. "off-test" energy use (e.g. related to tyres, air conditioning, headlamps, etc and by replacement components such as tyres and lubricants). Just how much fuel is consumed by such vehicle components is not well understood at present in both developed and developing countries. Lack of awareness on efficiency pay-back benefits and often low (or negative) net costs makes vehicle energy efficiency improvement an often underestimated potential source for energy savings and CO2 emissions reductions. Nevertheless, improvements in "off-test" energy use in motor vehicles can potentially save up to 20% in fuel consumption with little investments.

This workshop is organised to comprehend the full potentials of saving energy use by improving component efficiency of light-duty vehicles. In addition, discussions include facilitating developing countries deal with rapid private motorization and including components at an early stage in their policy packages, standards and regulations.
