Ford knows that one of the only ways it will be able to reach federal fuel economy numbers in the future is by putting its cars on a diet. Ford has already proven it can do this with the new F-150 losing hundreds of pounds by moving to aluminum body panels. Ford is now showing off an experimental Fusion that uses lightweight materials in an effort to shed weight.
The Fusion uses lots of aluminum and carbon fiber material in its construction. The finished product is a Fusion that looks the same as the current car, but weighs 23% less than normal. Less weight means that smaller engines can be used to achieve the same performance while using less fuel.
Ford is also talking up a plan to put lithium ion batteries and regenerative braking systems in cars other than hybrids. This tech is being investigated along with partner Samsung SDI. Ford says that the lighter Fusion should be able to achieve the same fuel efficiency as the Fiesta, a much smaller car.
