TfL are exploring the market to identify AVAS systems for their electric fleet.
EU legislation dictates electric vehicles below a certain speed need to have warning sounds (like when an HGV reverses).
'The introduction dates for the mandatory fitment of AVAS would remain as originally specified in (EU) No. 540/2014, i.e. the fitment of AVAS to pure electric and hybrid electric vehicles becomes mandatory from 1st July 2019 for new types of vehicle and from 1st July 2021 for all new vehicles, and any AVAS systems that are fitted voluntarily ahead of these dates must comply with the applicable requirements'
How about the AVAS is tweaked to make a bus engine sound?
