Nissan Motor Co. introduced a sedan developed for younger consumers in China as part of plans to lower the average age of its buyers in the world's largest car market.

The Lannia sedan will go on sale this fall, Nissan said at the Shanghai auto show on Monday, without giving a price range. The model was designed in Nissan's Beijing studio and is targeted at younger consumers who came of age during China's three-decade economic boom, an Internet-savvy generation of 240 million.

Capturing the under-35 market is crucial for automakers' prospects in China, where the average age of car buyers is 33, the lowest among major markets, according to researcher JD Power & Associates. The increasing purchasing power of this demographic group has inspired a wave of tie-ups between Internet companies and automakers to develop connected cars.
