EMPRESA MUNICIPAL DE TRANSPORTES DE MADRID, S.A. 9 Electric transmission buses - Mercedes CITO - 20 units years 2000/2001 - 8 and 9 m - 12 / 16 seats - 45 / 55 passengers -Low floor and ramp -Aluminium -Smooth ride - No batteries. Diesel engine as generator - Emmissions: lower that eq. ICE microbus - More efficient: better performance of cinematic flow EMPRESA MUNICIPAL DE TRANSPORTES DE MADRID, S.A. 10 Hydrogen: CUTE and CITYCELL projects Hydrogen bottles Feed unit air-hydrogen Fuel cell Air conditioned Transmision Electric engine EMPRESA MUNICIPAL DE TRANSPORTES DE MADRID, S.A.
