Manufacturers have until September 1st, 2019, to equip their vehicles with the new alert, but half of new hybrid & electric vehicles must be in compliance one year before the final deadline. This rule is to prevent these vehicles from injuring pedestrians.
Porsche, for instance, has been working on make its Mission E electric sports sedan noisier to satisfy sports car customers who prefer a growl when they gun the engine. Fiat Chrysler and McLaren are also aiming to inject some artificial engine noises in their electric vehicles.
