Increased productivity, reduced noise leads Trío Operadores to add Allison-equipped Econic NGT distribution vehicles

Trío Operadores Logísticos now has three Mercedes Econic NGT vehicles fitted with Allison
fully automatic transmissions, increasing both fleet productivity and driver satisfaction in
Madrid and Zaragoza.
MADRID – Since June 2014, a new Mercedes Econic NGT (Natural Gas Technology) fitted
with an Allison 3000 Series™ fully automatic transmission has been operating in Madrid. The
Trio Operadores Logísticos S.L. fleet vehicle delivers goods nightly to supply Simply Market
supermarkets, one of the operator’s most important customers.
The Clean Truck Project (Proyecto Camión Limpio), which began in May 2012, was the
result of a cooperative arrangement between Simply Market, Mercedes Benz and Trío
Operadores Logísticos. The goal was to make the unloading of goods more eco-friendly,
improving the efficiency of the fleet to the extent of reducing the number of vehicles
operating, while maintaining productivity and profitability. To achieve sustainable urban
distribution – less noise, less traffic and reduced CO2 emissions, a first compressed natural
gas (CNG) truck, a Mercedes Econic NGT, went into service delivering to Simply Markets in
Madrid. The introduction of this first vehicle allowed Trío Operadores Logísticos to take three
older trucks out of service.
Subsequently, a Mercedes Antos Euro 6 has been added to the fleet in Madrid and a gaspowered
Econic was added to the fleet in service in Zaragoza. In the third phase of the
project, the company purchased another Econic NGT for the Spanish capital, at the same
time relieving four older trucks of duty.
According to Javier Hernández de Vicente, director of Trío Operadores Logísticos, the highly
successful experience with the first Econic led to the addition of this latest truck:
“In the first stage of this project, we achieved a 33 percent reduction in urban delivery
emissions for the city of Madrid. With the addition of the second Econic NGT truck in the
capital, which will also operate at night, our aim is to achieve a reduction of 60 percent as
compared to initial emissions figure when the project began,” Hernández said.
Trío Operadores has a fleet of 150 rigid, refrigerated and general cargo vehicles, of which 25
are proprietary and the others are leased on a fixed-contract basis. The introduction of the
Mercedes NGT models enabled the company to reduce its proprietary truck fleet from 18 to
11 due to the Econic’s increased load capacity of 27 pallets. This enabled Simply to optimize
the number of delivery trips to its supermarkets.
The demand for fully automatic transmissions with torque converters in the urban distribution
sector continues to grow because they deliver significant productivity and performance
advantages over manual and automated manual transmissions, especially in combination
with natural gas engines.
“After two years, the experience with these transmissions has been extraordinary, above all
with respect to engine torque. The torque converter enhances gas engines’ torque at launch
and provides drivers with comfortable handling,” added Hernández.
Allison Automatics are the only transmission option in the Econic NGT, as it perfectly suits
the vehicle’s driveline. Allison’s Continuous Power Technology™ ensures smooth,
uninterrupted power transfer to the drive wheels, as well as superior vehicle launch due 
to multiplication of engine torque at low RPMs. Moreover, a key objective of trucks equipped
with natural gas engines is to reduce noise – by three to six decibels as compared to
equivalent diesel trucks – and the helical gear design of Allison automatic transmission helps
to achieve this goal.
The new Econic also features the Transgiro axle system, which enables a very small turning
radius to facilitate maneuverability and precision in the typically tight spaces created in dense
cities. In combination with the Allison Automatic, vehicle control and maneuverability on
roundabouts, corners, bends, loading and unloading ramps and other urban fixtures are
further enhanced. During maneuvering, the Allison torque converter allows for precise
inching control and smooth, low-speed motion. As clutch wear is no longer a problem,
vehicle maintenance is greatly reduced resulting in reduced ownership costs.
“Our reasons for once again choosing the Allison-equipped Econics are efficiency, driver
comfort, silent operation and reliability.” For Director Hernández, the benefits of an Allison
are very clear. “You don’t even have to think about the transmission, you just accelerate and
move forward,” he said.
