I come from a 2010 Prius so it is easy for me to apply the standard pulse and glide techniques to the CT, especially since it uses the identical power train. Though I am only halfway through my first tank, I am getting about 57 indicated (so about 54 actual) overall. City only driving nets me in the low 60s depending on traffic. The technique that I use in the city is rather simple. Accelerate so that the needle on the Hybrid System Indicator is at the top of the ECO band but not into the Power range. Your target is about 5mph above the speed limit. Once you've reach the target, immediately lift off on the accelerator and then reapply slightly until the Hybrid System Indicator is riding the line between Charge and ECO. If you are using the energy flow indicator on your nav screen, you are trying to achieve neither engine nor battery usage. This dead band is the most efficient. If you have trouble holding the dead band, try for as little battery usage as possible. Glide (coast) until you are about 5mph below the speed limit and repeat as needed. If there is a stop coming up, just keep coasting in the dead band until you need to use the brakes.
