Transport Minister Paschal Donohoe has launched Bus Eireann's new €50m "fleet of the future".
The 116 new buses will soon be used on services in Cork, Limerick and Galway, while some vehicles have already been put onto routes in the greater Dublin area.
The new buses have lower fuel emmissions, wifi, power sockets (on commuter coaches), extra legroom and monitors with live information. They are also wheelchair accessible.
It comes as passenger numbers continue to rise with 37.8million trips made last year - up 700,000 on 2014 figures.
Launching the additions to the fleet Mr Donohoe said: "As the economy continues to grow, there is a greater transport demand generally.
"I am glad to see passenger numbers for the company are on the rise and I look forward to seeing continued improvements and enhancements to our PSO bus services through the funding that government is making available for fleet and network improvements."
Passenger journeys in Cork city grew by more than 8% last year.
Given that two days were lost due to industrial action, Bus Éireann chief executive Martin Nolan said the figures were encouraging.
