Toyota said on Thursday that orders for its second-generation Prius hybrid sedan reached around 11,000 units in the first two weeks of sale, which compares to a month one target of 5,000 sales.

Toyota aims to sell 3,000 of the cars a month, or 36,000 a year, in Japan where it went on sale on September 1.

“Orders have come from wide-ranging age groups, from under-30s and over-60s,” Toyota said in a statement. Sales overseas will start later this year.

The previous Prius, launched in 1997, was the world’s first mass-produced gasoline-electric hybrid vehicle, and has sold over 120,000 units worldwide. Toyota hopes to sell 300,000 of the environmentally friendly vehicles annually by mid-decade.
