Car-sharing company Car2Go N.A. LLC announced Tuesday that its more than 30,000 San Diego members will have access to a new electric smart fleet starting Wednesday.

The new fleet will consist of 400 2014 models, an upgrade from its 2010 model.

"San Diego is fast becoming the nation's electric vehicle capital, and with the largest electric car-sharing fleet in the nation, we are proud to continue our commitment in preserving the local environment of our great city," said Car2Go San Diego Location Manager Will Berry. "The new 2014 vehicles, while maintaining the zero-emissions footprint, have a much smoother acceleration, and overall, a more comfortable Car2Go driving experience that our members will truly enjoy."

The company has seen more than 1 million Car2Go trips since its initial launch in San Diego in November 2011.

The company has also expanded to 45 square miles within San Diego, providing members greater flexibility to get to their destinations at their convenience without having to return the vehicle.
