Fuel efficiency rules in US mandate passenger vehicles to achieve 54.5 mpg average by 2025. Meeting this big challenge requires new technology, including large reductions in vehicle mass. Is a lighter vehicle less safe in crashes? What does it imply for manufacturers and for customers? How important is vehicle’e mass in assessing product liability? Should the vehicle’s mass be considered a factor in investigating accident causation and the injury causation?
Intelligent tires-and-vehicle systems, in which tire-embedded sensors are integrated with vehicle-based controls to optimize the vehicle’s energy efficiency and safety, are a major step towards achieving transportation sustainability.
