What happens when Altair's
engineering experts &
simulation technologies
set their sights on public transportation?
An ultra-lightweight,
hybrid propulsion bus with
2X the fuel economy
at lower lifecycle cost!
The most
hybrid bus
ever designed


The list of innovations goes on...

  • Engineered with Altair's technology and design process to make it the lightest bus in the industry
  • Series Hydraulic Hybrid Powertrain
  • Designed to take advantage of the inherent benefits of an all aluminum body and chassis
