The Toyota Prius has become an icon for environmental awareness and high fuel economy and many owners appreciate that the distinctively styled Prius speaks volumes about their awareness. The drawback is that Prius is too restrained and simplistic for buyers who are considering an entry-level luxury model. The Lexus HS 250h is a more luxurious vehicle designed to fulfill that need. The HS is a dedicated hybrid model with a powertrain similar to that of the Prius. However, the HS has a larger, more powerful gas engine.

The new HS 250h is a dedicated full hybrid model which also serves as Lexus's new entry-level vehicle. The gas engine is a 2.4L four cylinder and when paired with the electric motor produces a net of 187 horsepower.
