Advantages:
- Enhanced torque for better acceleration and towing
- Slightly better fuel economy in city driving
- Lighter weight, benefiting handling and agility
Potential Downsides:
- Turbo lag can be experienced under certain conditions

Why it stands out:
- Superior torque for towing (up to 3,500 lbs)
- Outstanding fuel economy for a diesel option
- Better longevity if properly maintained
Note:
The EcoDiesel was initially unavailable on the 2021 models but made its way into later releases—double-check your specific trim for availability.
