Close
Unlike previous models, the MF 77 was designed for travel into the immediate suburbs of Paris, and as a result has a maximum speed of 100 km/h (62 mph) which has yet to be fully utilized. In addition, it sports a new, curved silhouette with a wider midsection. Its original exterior colors, blue and white, led passengers to refer to it as le métro blanc, or white metro.
