Which Ford Transit Custom model has the best fuel efficiency?

I am planning to buy a Ford Transit Custom for my business and I am wondering which model has the best fuel efficiency. I am looking for a model that can save me on fuel costs in the long run. Any recommendations?

Based on my experience, the Ford Transit Custom 300L is the most fuel efficient option. It has a great balance between power and efficiency, making it perfect for business use.

I suggest going for the Ford Transit Custom 300S. It has a smaller engine but still has enough power for daily use. Plus, it has lower fuel consumption compared to the other models.

I highly recommend the Ford Transit Custom 320L. It may have a higher price than the other models, but its advanced fuel-saving technology makes it worth every penny.
