The invention discloses a dual mass flywheel which comprises a first mass flywheel, a second mass flywheel and a vibration damping device. One side of the first mass flywheel is connected with an engine; the other side of the first mass flywheel is connected with a flange plate; the second mass flywheel is connected with a speed changer; the vibration damping device is arranged between the first mass flywheel and the second mass flywheel, drives the flange plate so as to drive the second mass flywheel to rotate, and comprises multiple arc-shaped elastic pieces uniformly distributed along the periphery of the flange plate; the first ends of the arc-shaped elastic pieces are connected with the flange plate; and the second ends of the arc-shaped elastic pieces are connected with counterweightpieces for stretching or compressing the arc-shaped elastic pieces. The invention further discloses an automobile with the dual mass flywheel. Compared with the prior art, according to the dual massflywheel and the automobile provided by the invention, the number of components of the vibration damping device is less, the cost is low, the problem of large noise during starting and stopping the engine is effectively solved, and a vibration damping effect is better.
