The world's first dedicated luxury hybrid (is not just an upgraded Prius)
Those stats sound a lot like the Toyota Camry Hybrid
Bingo! Although Lexus didn't explicitly say so, the 650-volt battery pack, 2.4-liter gasoline engine and 40-hp electric motor all duplicate the Camry hybrid's components statistic for statistic. The Lexus HS 250h even has similar mileage to the Camry hybrid. While the drivetrain may not be exclusive, this sharing of components could help hold the line on price.
