Ford’s latest concept car is a familiar figure with a mind-blowing mass. It’s not just the skeletal paint-job – the Fusion you see here is built from the ground up with completely new materials.

Shedding about 25% of its current weight, the Ultra-Light Fusion concept balances the scale with the Fiesta, Ford’s smallest car. Its a powerful mix of carbon fiber, aluminum, magnesium, and high-strength steel that makes this grand sedan 800 pounds lighter.

The car’s wheels and seats are carbon fiber, while its crankshafts, springs and stabilizer bars are hollow steel. For the body, Ford opted to use a combination of aluminum, high-strength steel and magnesium.

The windshield and most of the windows are made out of chemically treated glass that is partially Gorilla Glass — used in earlier iPhone models — while the rear window is plastic.

The engine has also been slimmed down to a one-liter, three-cylinder EcoBoost engine that Ford said performs much like the regular Fusion, but has the fuel economy of the smaller Fiesta (about 45 MPG).
