So I know lots of people such as taxi drivers prefer the Prius as its fuel efficient, but in reality how efficient are they compared to other modern cars?
Case in point, I recently purchased a 2013 Mercedes A180, and with features such as cutting the engine at idle, adaptive cruise control, etc. it is very fuel efficient. I have also assumed that the Prius with all its extra weight and complexity of its drive train wouldn't yield that much of an increase in efficiency.
And I wrong? What does a Prius return in real world driving compared to ICE cars?
