Mazda Motor Corp. on Monday began marketing its first new offering in 18 months -- a midsize car called the Atenza.

The Atenza, featuring low fuel consumption and emissions, went on sale in two models -- a sporty five-door version priced at 2 million yen to 2.3 million yen, and a four-door sedan priced between 1.8 million yen and 2.36 million yen.

The Atenza is available with a 2,300cc four-cylinder DOHC engine or 2,000cc four-cylinder engine, Mazda said.

The vehicles will be sold as the Mazda6 overseas, according to the automaker, which is owned 33.3 percent by Ford Motor Co. of the United States. The company set a domestic sales target of 2,500 units per month.

Mazda said it will put the station wagon version on sale June 24. It will be priced at 2 million yen to 2.3 million yen.
