The Hyundai Sonata hybrid is being delayed to make it compliant with new noise regulations imposed by the government for hybrid and electric vehicles.

Out of compliance

Sonata hybrid just doesn’t sound right

Because of new government regulations requiring an artificial engine noise for hybrid and plug-in vehicles when in electric mode – when the cars are virtually silent, at least compared to conventional cars – the Hyundai Sonata hybrid has been delayed.

Rather than begin selling Sonata hybrids that would only have to be recalled later, Hyundai has decided to upgrade their sound systems before delivery.

According to AutoWeek, Hyundai originally added a new sound system to the Sonata hybrid, but the system included a switch that enabled drivers to shut the artificial noise off. Under new government regulations, however, such a switch is in violation of the new law. Consequently, Hyundai is removing the switch.

Deliveries should be back on track in late March or April.
