Hy-wire is a hydrogen fuel cell combined with by-wire technology. It is the product of a global cooperation of GM designers and engineers in the United States and Germany in association with the SKF Group from Sweden and the Italian design house Stile Bertone. It is GM's second version of this type of technology first introduced with the AUTOnomy concept unveiled at the 2002 North American International Auto how in Detroit.
The real interest of this concept has to do with the way the chassis incorporates the propulsion and control systems inside an 11-inch thick skateboard-like platform. The 4-door sedan body is extremely roomy thanks to the absence of a traditional engine compartment. To demonstrate the new architecture, both front and rear panels are made of glass. The Hy-wire weighs in at 1 900 kg and sports 20" wheels in the front and 22" wheels in the rear. The transversely mounted electric engine develops a maximum of 60 kilowatts (80 hp) and a maximum torque of 215 Nm (159 lb/ft).
