The new LS went on sale Thursday at a price starting from ¥16.32 million ($148,800). The Mirai will be sold from Monday, priced from ¥8.45 million, the company said. The autonomous driving technology equipped with the new models is a level-2 assistant system that could help with driving on an expressway or other motor-vehicle-only roadway. The technology can help with keeping the vehicle in its lane, maintaining the distance from other cars and navigating a lane splitting.
