Specifically, the development of specially engineered, low-rolling- resistance tires designed to further improve the fuel economy of its cars and crossovers.
Four of Ford 's vehicles rated below 5.0 L/100km - Fiesta SFE, Focus SFE, Fusion Hybrid and Lincoln MKZ Hybrid - come fitted with these special, fuel- saving tires. In addition, the 2011 Ford Taurus, 2011 Ford Edge, 2011 Ford Fusion and 2011 Ford Explorer have tires with enhanced technology that helps improve fuel economy.
Rolling resistance, a measure of the force required for the tire to travel down the road, is a key attribute in improving fuel economy. A 10 per cent improvement in rolling resistance leads to a fuel economy improvement of as much as two per cent, according to Ford’s tire experts. Ford’s tire team, a dedicated group of scientists studying the chemistry of tires, is also researching materials found in other products. Such as athletic shoes, to see if there is potential for automotive application. The team is working with tire suppliers and manufacturers to evaluate these materials and ultimately to bring improved tires to market faster.
The 2011 Ford Mustang coupe, for example, is the first car to achieve a combination of 305 horsepower and 6.4 L/100km (hwy).
Optimal tire pressures can also have a beneficial effect on fuel economy, which is why all Ford and Lincoln vehicles are available with tire pressure monitoring systems that alert the driver when pressure falls below a set level. Under-inflated tires can be a safety hazard in addition to lowering fuel economy.
