Transmilenio Acquires New Fleet of Scania Bi-articulated Buses equipped with Allison Automatics

The new Scania natural gas bi-articulated buses comply with the Euro VI emissions standard, the most advanced in the world, which significantly reduces polluting emissions.

BOGOTÁ, Colombia, January 2021 — The Integrated System of Mass Transportation SITP (Transmilenio) of Bogotá, considered the largest Bus Rapid Transit (BRT) system in the world for mobilizing around 2.5 million citizens per day, completed Phase 1 and 2 of its Bus renewal plan, with the start of operations of their new fleet of 562 Scania F340HA 8x2 CNG Euro VI bi-articulated buses with Allison fully automatic transmissions.

The Scania F340HA buses with Allison transmissions are 27 meters long and constitute the largest fleet of CNG Euro VI bi-articulated buses in the world and the largest sale made by Scania Brasil and bodywork by Colombian companies.

In addition to being sustainable and environmentally friendly vehicles, they bring with them a much larger space for users with a capacity of up to 250 passengers. The buses are equipped with the latest generation Allison B516R fully automatic transmission that pairs with the Scania O9 CNG Euro Engine VI to reduce particulate matter (PM) and nitrogen oxide (NOx) emissions by more than 95 percent, and global carbon dioxide (CO2) emissions by more than 20 percent, compared to buses that currently circulate in the city with Euro V technology or lower.

“Allison automatic transmissions bring many benefits to vehicles. In the first place, it facilitates driving since the changes will be made within the appropriate ranges, avoiding over-revving the engine, or working at revolutions lower than those of the highest efficiency range,” said Jhonny Pineda from Capital Bus “Also, it allows you to keep both hands on the wheel and improves ergonomic and safe-use conditions for the driver. They also help reduce stress, blood pressure, and the driver's heart rate, and subsequent absenteeism.” The Allison B516R transmission has the advantage of having a built-in retarder. The use of a retarder allows smooth decelerations, reducing brake system wear and consequent repairs. An Allison fully automatic transmission does not have clutches, which reduces maintenance costs and downtime.
