In the first two installments of Cars.com’s Mileage Challenge, we took you through our daylong city drive to see what sort of real-world gas mileage various hybrid cars serve up. Each hybrid in our challenge had a battery of displays to convey instant and cumulative fuel economy. Some also had power flow displays or mileage history readouts, while others had meters showing the amount of electric boost or how much braking energy was recharging the battery. That’s a lot of information, and each car had a different take on how to convey it. Naturally, some did better than others.
