Toyota Motor Corp. has unveiled the latest version of its Harrier luxury crossover vehicle, featuring a new design and better fuel economy to attract younger customers.

The Harrier, known in overseas markets as the Lexus RX, was fully revamped for the first time in 10 years. Toyota plans to roll out the gasoline model Dec. 2 and the hybrid version Jan. 15.

The hybrid, which combines a 2.5-liter gasoline engine and hybrid system, offers fuel efficiency of 21.8 km per liter, while retaining the characteristic power of a sport utility vehicle and achieving class-leading environmental performance, Toyota boasted Wednesday.
