FRANKLIN, Tenn., Feb. 6, 2013 /PRNewswire/ -- The all-electric Nissan LEAF may be known for being quiet on the outside, but now it's boomin' on the inside with the first custom-designed Bose® Energy Efficient Series sound system available on the 2013 model that goes on sale this month.

"Early adopters of electric vehicles were thrilled to have a zero-emissions vehicle and now that we're expanding the market and it matures, many customers are asking for more amenities in their EV," said Brendan Jones, Nissan director of EV marketing. "We wanted to be able to give them a premium sound system and be conscientious about the amount of energy required to do so." Nissan, which now assembles the LEAF, its battery and its electric motor all in Tennessee, introduced an expanded range of trim levels for the 2013 LEAF. The Bose system is available as part of the premium package on SV and SL models. "The Bose Energy Efficient Series sound system delivers on all its promise for LEAF owners. It's remarkably efficient—without conceding on great musical performance," said Brandon Westley, president of the Bose Automotive Systems Division. "This system also demonstrates the unmatched advancements we've achieved in producing highly efficient audio technology in vehicles." To meet the energy efficient design goals for the LEAF, Nissan engineers focused on using every available watt of power effectively throughout the vehicle, including the sound system. Bose expertise in power-efficient technology led to the development of smaller and lighter speakers and amplifiers that perform at a high level without compromising the LEAF's power, weight or interior space.
