What is the most fuel efficient Vauxhall Vivaro model?

I am looking to purchase a Vauxhall Vivaro for my business and am wondering which model is the most fuel efficient. I will be using it for long distance deliveries and want to minimize fuel costs.

The Vauxhall Vivaro 2.0 CDTI BiTurbo is the most fuel efficient model, with an average of 55 miles per gallon.

I recommend the Vivaro 1.6 Turbo D for your needs, as it has the best fuel economy for long distance driving.

You should also consider the Vivaro-e, which is the electric version of the Vivaro and has zero emissions. While the initial cost may be higher, the long term savings on fuel can make it worth it for your business.
