Ask an expert

I have owned a '86 Toyota Townace with a 2.0 Ltr petrol engine for going on 15 years, however it is getting a bit old and shabby so I am looking to replace it with another coach.

All the vehicles I have considered seem to be very thirsty compared to my 22 year old Toyota which gives a average of 30 mpg.

For instance the Nissan Elgrand is quoted at 19 mpg (14.8 L/100km) whilst the Toyota Granvia is little better at 22 mpg (12.8 L/100km).

Why is it that old and tired technology seems superior to the more modern?

Also, finding fuel consumption figures is a long and arduous task, is there no site which gives comprehensive and up to date information?

To be fair ,it is difficult to make proper comparisons with vehicles that have over 20 years in age difference between them.

Vehicles today have much better performance figures and carry more accessories on-board as standard, than vehicles twenty years ago.

Take power steering and air-conditioning for example; it takes energy to drive the compressor and the power steering pump which adds load to the engine. And people like to have, and expect these comforts.

On the plus side late model vehicles are so much improved in safety (more additional weight) and reduced emissions.

Accurate fuel consumption figures are always difficult to find especially for used imports.
