4-cylinder (Zetec):
* Pros: Better fuel economy, typically cheaper to maintain (parts and repairs are generally less expensive), lighter weight (can improve handling slightly).
* Cons: Less powerful, may feel less refined (more vibration and noise), may struggle with heavier loads or towing.
6-cylinder (Duratec V6):
* Pros: More powerful, smoother operation (less vibration and noise), better for towing or hauling, potentially more responsive acceleration.
* Cons: Lower fuel economy, more expensive to maintain (parts and repairs are generally more costly), heavier weight (can slightly impact handling).
Ultimately, the "better" engine depends on your needs:
* Prioritize fuel economy and lower running costs: Choose the 4-cylinder.
* Prioritize power, smoother operation, and towing capability: Choose the 6-cylinder.
Consider also the year of the Contour. The engine options and their relative performance might vary slightly between model years.
