What engine is most efficient for the Ford Transit Custom?

I've been looking into purchasing a Ford Transit Custom but I'm not sure which engine would be the best in terms of fuel efficiency. Can you provide some insight into which engine is most efficient for this vehicle?

In my experience, the 2.0 liter EcoBoost engine is the most efficient option for the Ford Transit Custom. It offers a good balance of power and fuel efficiency.

I highly recommend the 1.5 liter EcoBlue diesel engine for the Ford Transit Custom. It has great fuel economy and is perfect for long distance travel.

Although it may not be as powerful as the other engine options, the 2.0 liter diesel engine is the most fuel efficient engine for the Ford Transit Custom. It's a great choice for city driving.
