I have been driving a Toyota Premio 1.8cc, 1997 model but I want to change cars

I have been driving a Toyota Premio 1.8cc, 1997 model but I want to change cars. These are my options:
-Toyota Premio 1.8 cc
-Toyota Premio 1.6 cc
-Toyota Probox 1.8 cc
-Toyota Noah 2.00 cc
Please advise me on which of these cars I should probably go with that is efficient in fuel consumption and has relatively good performance.

Mr Arinaitwe, the smaller and more aerodynamic saloon cars (Premio) would be more fuel efficient than the multi role passenger/utility cargo carrying van (Probox) or the six to eight passenger mini-passenger van (Noah).
Interestingly the 1.8 litre Premio may have a better balance between fuel efficiency and good performance when compared with the 1.6 litre depending on the passenger load and need to accelerate.
With the Premio, your trade off for better fuel efficiency would be: less passenger and cargo capacity.
Needless to say there are other factors that also affect fuel efficiency such as: your driving style (aggressive, abrupt braking), engine maintenance (choice of oil and fuel) as well as tuning, condition of tyres.
