Passenger transportation by rail systems requires less energy than by car or plane (one seventh of the energy needed to move a person by car in an urban context, [45]). This is the reason why, although accounting for 9% of world passenger transportation activity (expressed in pkm) in 2015, rail passenger services represented only 1% of final ...
Example energy flows for a late-model (pre-2009) midsize passenger car: (a) urban driving; (b) highway driving. Source: U.S. Department of Energy [4] [5] Most of the fuel energy loss in cars occurs in the thermodynamic losses of the engine. Specifically, for driving at an average of 60 kilometres per hour (37 mph), approximately 33% of the ...
Environmental regulations in developed countries have reduced the individual vehicle's emission. However, this has been offset by an increase in the number of vehicles, and increased use of each vehicle (an effect known as the Jevons paradox). [3] Some pathways to reduce the carbon emissions of road vehicles have been considerably studied. [5]
For instance in a 0.9g turn, a car with a track of 1650 mm and a CoM height of 550 mm will see a load transfer of 30% of the vehicle weight, that is the outer wheels will see 60% more load than before, and the inners 60% less. Total available grip will drop by around 6% as a result of this load transfer.
