Independent experts at CAP found the all-new S-Max and Galaxy models offered the biggest rise in residual values over the outgoing models of £1,275 and £825 respectively.
Meanwhile, the updated Ford Mondeo, released this month, offered an improved residual value of £175.
Experts estimated the residual values of the models over three years and 60,000 miles. New exterior design, more equipment, improved technology and more efficient powertrains were the main reasons for the improved figures, said CAP.
CAP’s manufacturer relationships manager, Martin Ward said: “When looking at the new Ford S-MAX against the outgoing model side by side, the differences are obvious.
"With the added benefit of more efficient powertrains, this vehicle is an even better proposition for new car buyers”, he added, “and with a seven-seater sports car design, it will continue to appeal greatly to the user car buyer.”
The lower CO2 emissions in the Ford models, and subsequent lower tax, could save drivers more than £1,000 a year.
In the updated Mondeo, £135 can be saved over three years in road tax because of lower CO2 emissions of just 139g/km.
The three models, on sale this month, could cost up to £3,500 less than outgoing versions, according to Ford.
The Mondeo, S-Max and Galaxy cost from £17,295, £20,645 and £22,945 respectively.
