The Colonial was an American automobile manufactured in 1920 by the Mechanical Development Corporation of San Francisco. The car came with a straight-eightengine; it also featured disc wheels, with an extra pair mounted at the side as spares. The body was a hardtop, calibrated so that the driver could turn it into either a sedan or a touring car simply by rearranging the windows.〔 Production models were to sell for $1800, but only the prototype was completed.〔 The Colonial is chiefly remembered today because it was the first American car to feature four-wheel hydraulic brakes. The Mechanical Development Corporation announced in 1924 that the 1921 prototype would be put into production in a new $2.5 million factory which could build 12,000 cars a year, but these plans never eventualized.〔 The prototype Colonial still survives.〔 ==See also== *Colonial (1921 automobile) *Colonial (Shaw automobile) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Colonial (1920 automobile)」の詳細全文を読む スポンサード リンク
