Volkswagen is reinventing the Beetle again.

The company is introducing an edgy new design for the car on Monday. It's giving it a flatter roof, a less bulbous shape, narrowed windows and a sharp crease along the side.

It's the first overhaul of the Bug since 1998, when Volkswagen came up with the New Beetle.

VW wants to triple its U.S. sales of cars and trucks over the next decade. It says the changes to the Beetle will appeal to more buyers, especially men. But the changes could also anger fans, who love the little four-seater for its huggable curves and perky attitude.

Even if it satisfies its fans, the third incarnation of the Beetle will have to compete in a U.S. small-car market that is bigger and more competitive than it was in 1998.
