In Detroit, in 1902, Henry Leland produced the first Cadillac. His company later became a part of General Motors. Some 200 years earlier, Antoine Cadillac (born on this date in 1658) had founded Detroit, which was to become the "auto capital of the world." Speed ahead another 100 years: GMC subsidiary Chevrolet has come out with its electric car, the Volt. The new vehicle will operate either as a straight electric car that fully charges in six hours or with a one-liter engine that runs at a continuous speed, replenishing its batteries; it is expected to go into production in 2010.
