Audi commissioned the design of a 49-foot trimaran motoryacht to showcase its diesel-engine technology and its commitment to the environment. It also promotes Audi’s “brand values — progressive, sporty and premium.” Designed in Germany by Stephanie Behringer, under the watchful eye Audi Concept Design, the low-resistance yacht will be powered by two turbocharged direct-injection V-12 diesel engines mounted in the main hull. Top speed is about 30 knots. A pair of electric PWCs, one in each ama, provides all the thrust the yacht needs at speeds up to 8 knots when the wind, current and seas are light. A charging system run off the main engines recharges their batteries.
