With fuel prices for combustible engine automobiles increasing, researchers and manufacturers have given more attention to the concept of an ultralight

car. Using carbon composites, lighter steels and plastics, a fuel-efficient car

can be manufactured at 540 kg. How much less does an ultralight car weigh

compared to a 1450-kg Honda Accord (2007)?
