Japan's Toyota Motor Corp. on Monday unveiled the latest lineup of its flagship Crown series featuring for the first time a hybrid engine and a safety system to make sure drivers are fully awake.
Toyota is expected this year to move past Detroit giant General Motors as the world's top-selling automaker, in part due to its success in pioneering eco-friendly hybrid cars at a time of high prices at the pump.
Toyota introduced three models of its Crown, its flagship domestic line, including one with a petrol-electric hybrid engine.

The new models to be sold in Japan are installed with a pre-crash safety system, billed as a world first by Toyota, which detects if drivers' eyes are fully open, the company said.

Once the system catches that a driver's eyes are closed for a while, it gives out an alert and forces the vehicle to stop when a risk of collision arises, the company said.
