Industry standards (US) for car CO2 emission, result in target level of 163 grams/mile CO2 emission for model year 2025 which is equivalent to 54.5 miles per gallon (mpg).


  • Reducing a vehicle’s weight by 10 percent can improve the fuel economy by ~ 6 to 8 percent.
  •  10 Kg Weight reduction presents ~ 1.6 g/mile CO2 reduction.

  • Car weight should be reduced by around 28% in the next 10 years (Average reduction of 400 Kg per car).

Manna understanding of car light weighting challenge is based on its long years support for projects involved in converting metal structural and semi structural components to plastic.
