  Project Whisper - the city bus technology of the future



e-Traction implemented the e-Traction system with TheWheel SM500/3 motors in standard city buses - the result is an amazing fuel consumption reduction up to half normally used.

In close cooperation with community Apeldoorn, Veolia, province of Gelderland, the Dutch government and Eneco - 5 buses are now being converted to Whisper buses. The project started December 2008 and is now in full swing.

Phase of Project - 50% completion

First bus has been delivered and is in daily operation. Second bus is being rebuilt and 60% ready.

What makes the Whisper a revolutionary bus concept

As with any vehicle equipped by e-Traction, TheWheel in-wheel motors are installed as traction system. Using this technology, an enormous energy consumption reduction is already achieved. For more information, see our TheWheel overview section

Batteries
The next step in transition is adding an energy buffer. As elaborated in the e-Traction system section, Li-Ion batteries are installed. The capacity of this buffer allows zero-emission electric driving up to one hour of operation.

Generator
An well designed buffer allows the use of a smaller power source. Every Whisper bus is equipped with a small diesel generator. Its size is comparable with a small SUV motor - as is its fuel consumption.
