I am teaching a 9th grade physical science class. We are studying efficiencies of machines. I want to be able to compare the efficiencies of a diesel Mercedes to the Tesla S. The engine efficiencies seems misleading, with the diesel maybe at 50% and the Tesla electric at 80%. Is there data on the complete system for the Tesla and the Mercedes?
