Soundproofing the vehicle

One of the biggest advantages with electric vehicles and hybrids, is the lack of engine noise when the vehicle is not moving or moving at low speeds. Soundproofing was added to the rear of the passenger cabin to help reduce the noise created through road noise and the IC generator. This was achieved by building a sound wall, adding a sound box around the IC engine, and through modifying the muffler of the IC engine.

This is a view of the Geo Metro muffler that was adapted to fit the IC engine we have.
