What are the most important engine specifications to consider when purchasing a Ford Fiesta?

I am having trouble deciding on which engine to choose for my Ford Fiesta, what are the key factors I should consider for optimal performance?

I suggest looking at the available horsepower and torque options based on your driving needs. Consider what kind of driving you do most frequently - city versus highway - to determine which engine will best suit you.

Fuel efficiency is also an important factor to consider. Look at the fuel economy rating and calculate how much money you could potentially save in the long run by choosing a more efficient engine.
