Hybrid cars wil get better mileage under highway driving conditions as is the case with most cars. Stop and go city driving uses a decrease in efficiencey in any vehicle type.
It depends on what type of driving you do. Hybrid vehicles tend to get the best mileage while driving in city traffic. The increase in mileage in the city is due to the increased used of the electric motor. Most hybrids (the notable exception is the Chevy Volt) will not use their electric motors while cruising down the highway. If you tend to do more highway driving, you will likely get better gas mileage by driving a vehicle with a diesel engine. Modern diesel engines run very smoothly, reliably, and cleanly. They also have the advantage of being less complicated than a hybrid vehicle while getting comparable highway mileage. City mileage in a diesel vehicle will be better than a regular car but not quite as good as a hybrid.
