The exterior design of the MF 01 was the result of a design competition, and the winning design is similar to the
MP 89. The interior also looks similar to MP 89's interior, carrying on features like
interconnecting gangways between cars, but with new security features added. The MF 01 is the first rolling stock type on the Paris Metro to feature a refrigerated ventilation system inside the driver's cabs and passenger interiors, specially designed for the Metro's restricted
loading gauge, which consumes less electricity than traditional
air-conditioning. Additionally, the MF 2000 consumes 30% less energy than its older counterparts due to innovations in traction and braking systems. Currently, pre-production train #001 contains the
Dilidam multimedia system. Although all of the MF 01 trains are configured in a way so that the system can easily be installed, high cost has delayed implementation to all trainsets. The same train, in August 2014, became the first set to be repainted in the hybrid RATP/STIF livery and permanently reassigned to Line 9, having originally ran on Line 2. == Deliveries to Line 9 ==
