Both cars feature the new seats, which are made up of recycled rubber from tyres from old Ford cars as the manufacturer attempts to reduce the environmental impact of its small car range.
So far, Ford has recycled more than 2.2 million points of rubber for the Fiesta and the Focus since the introduction of the scheme in 2008.
For Ford drivers, the benefits do not stop at the environmental impact. The seats are lighter than conventional seats, saving weight and improving fuel consumption figures on the cars.
The seats join other environmental innovations such as soy foam seats cushions, recycled yarns on seat covers and wheat-straw-filled plastic in new Ford cars to reduce the overall impact of building them.
On the surface, Ford has striven to improve CO2 emissions and fuel economy in its cars to benefit the environment and running costs for customers.
This is most notable in the new Ford Focus, where ECOnetic diesel models deliver 109g/km of CO2 emissions while even the least efficient versions return just 139g/km.
In the case of the Ford Fiesta, 1.6-litre diesel engines offer CO2 emissions as low as 95g/km, enough to qualify for zero Vehicle Excise Duty (VED) and exemption from the London congestion charge.
Fuel economy for the three- and five-door Ford Fiesta is as high as 78.5mpg, making the 2011 Ford Fiesta one of the most efficient small cars on the market.
Technology such as Start/Stop, low rolling resistance tyres and aerodynamic improvements to the body work offer reductions in fuel consumption, while advances such as using recycled rubber in the seats has put Ford in a leading position in terms overall carbon footprint of its cars.
"Our team continues to develop new technologies that reduce our environmental footprint," said Dr. Debbie Mielewski, technical leader, Plastics, speaking about the environmental upgrades to Ford’s two most popular models.
