Convert your existing COBUS fleet into electric. Reduce carbon footprint and halve operational costs.

One of the benefits of our COBUS is its flexibility. Technology is changing quicker than the life time of the equipment, especially considering the fact that with the aluminium body of the COBUS 25 years can easily be reached. What about the emission standards? If electric is the future, you can either consider a new e.COBUS or you convert your existing COBUS fleet into electric: We call it e.START.

The e.START is the sustainable way, which we, COBUS, offer our customers. Removal of the diesel engine, assembly of electric drive train and battery packs on the roof make your COBUS emission-free. Repurpose of over 80% of the material makes the e.START an up-to-date solution for a better future. At the same time it offers the opportunity to overhaul your COBUS and to modernize your applications inside the COBUS.

Benefits of the Conversion

  • Flexibility» Fleet management saves operational and maintenance efforts
  • Technology» Opportunity charging without impact on battery life time


At present, our e.START concept has already successfully been tested and experienced at three European airports. How did it come about? Read for yourself!

e.START and e.COBUS alike

With an existing wide fleet of diesel powered COBUS,

our customer Geneva Airport had started the transition towards electric some years ago. Until today, we have delivered not less than 12 units of electric powered buses which is a combination of e.START (converted from existing diesel COBUS to electric) as well as brand new e.COBUS, with the aim to reach a fully electrified fleet by 2025. Let’s take this opportunity to say thank you to Geneva Airport for their continuous support and fruitful partnership!

2 e.STARTs at Salzburg Airport

Due to the requirements of the Austrian government,

Salzburg Airport already started the conversion to fully electric airport buses in 2018 and used our e.START concept, which converts diesel COBUSes to all-electric drive. This first e.START was handed over to the airport in August 2018. The second diesel-powered COBUS 3000 was delivered back to Salzburg in December 2020 as a completely refurbished e.START. We are very pleased that we were able to support Salzburg Airport in implementing the legal requirements!

How the electrification began

Our very first e.START test bus

was provided to our valued customer, Stuttgart Airport, in 2014 as part of an EU pilot project for electrically powered ground equipment. Due to the consistently positive results gained during this test phase, Stuttgart Airport switched completely to the e.COBUS 3000 in the following years. In the meantime, Stuttgart operates an impressive fleet of 18 e.COBUS 3000.
