What is the best engine for the Ford Transit Custom?

I am looking to buy a Ford Transit Custom, but I'm not sure which engine is the best choice. Can you recommend one and tell me why it's the best?

The 2.0L EcoBlue diesel engine is the best choice. It offers a good balance of power and fuel efficiency, making it suitable for both city and highway driving.

I would say the 2.0L EcoBoost petrol engine is the better option. It delivers excellent acceleration and a more spirited driving experience.

I suggest going for the 2.0L Bi-Turbo diesel engine. It has higher torque and can handle heavier loads, making it ideal for commercial use.
