Well you can get more efficient while using less fuel, compare 2014 Civic to a 2010 Civic. According to EPA, the 2014 gets 2-4 more MPG while having more horsepower (I think it's like a 5HP difference, but still).
You can also compare 1990 Ford F150 V8 to a 2014 Ford F150 V8 and you have a bigger engine on the 2015 and get better fuel economy according to EPA.
This should show how much room for improvement there is on cars without converting to a hybrid or all electric vehicle.
