William D. Bond (born January 2, 1931) is an American inventor and mechanical engineer who retired from General Motors after spending his entire career with the car maker.
A member of the engineering staff, Bond worked for General Motors (GM) from July 1960 until his retirement in February 1993.
His early work involved one of GM's earliest electric cars, the Electrovair II, a 1966 Corvair Monza sedan powered by silver-zinc batteries.
The battery pack gave the Electrovair II a similar performance to that of the conventional gasoline powered Corvair which the car was based on with a top speed of 80 mph.
As the project manager of the Electrovair II, Bond served as the spokesperson and driver when the car was demonstrated to the press in October 1966.
