Toyota Motor Sales U.S.A. Inc. says it will debut for the first time a “new dedicated hybrid concept vehicle” at the North American International Auto Show in Detroit next month.

The world unveiling will take place Jan. 11, with Toyota offering no further details.

Just last week Toyota Div. Vice President Bob Carter told Ward’s the Detroit show would be a big one for Toyota in terms of hybrid-electric vehicle news, as well as news about other alternative powertrain vehicles.

“What you can expect from us is a very clear corporate vision with regard to our hybrid (vehicles) and our environmental strategies,” Carter said last week at a media event in California.

Carter said Toyota’s Detroit HEV news would include both new and next-generation models.

The auto maker is working on an HEV version of its Yaris compact car and has been studying expanding its Prius HEV lineup to include more than one model.
