Transports Metropolitans de Barcelona (TMB) resolved a few days ago the tender called to acquire 46 natural gas hybrid buses to continue the renewal of its fleet, made up of 1,140 vehicles. The winners were the manufacturers MAN and Evobus, for an amount of 20.1 million euros. The new buses will be incorporated into the TMB’s fleet in the first quarter of 2021.
This acquisition will also allow an increase in the environmental quality of the mobile sources, since the 46 new CNG hybrid vehicles (combination of thermal and electric engine) will replace 14-year-old buses with the advantage of lower consumption and emissions.
The 46 buses have been acquired in two lots, the first of which is made up of 30 12-meter standard vehicles, which was awarded to MAN Truck & Bus Iberia for an amount of 9,675,000 euros plus VAT, while the second batch consists of 16 18-meter articulated buses that will be supplied by Evobus Ibérica for a value of 6,939,200 euros plus the corresponding VAT.
All vehicles will have the usual comfort and accessibility features in the new TMB fleet. Regarding safety technology, they will have a driving assistance system based on frontal and blind spot sensors, active at all times, which will generate audible and visual alerts when there is an imminent risk of impact, run over or collision.
It is the first time that TMB contracts new buses that combine electric and CNG engines. The 13 vehicles with this technology that are currently part of the fleet were built from conventional natural gas vehicles to which two electric motors, a generator and other components were added, in an innovative project developed by TMB and Gas Natural Fenosa in 2012 -2013 in the context of the first environmental conversion of the Barcelona urban bus fleet.
The hybrid system makes it possible to further reduce the low polluting emissions of CNG vehicles compared to a conventional vehicle, since it is applied on a motorization that is considered as an enhanced environmentally friendly vehicle (EEV) because it emits almost no particles and reduces NOx by 90% compared to a diesel engine.
