Lexus HS 250h
Lexus brought the promise of sustainable luxury to the forefront of the auto industry when the world’s first dedicated luxury hybrid, the HS 250h, went on sale in August 2009. The HS 250h demonstrates innovative engineering and intelligent, driver-inspired design while offering excellent roominess and nimble maneuverability. Lexus’ first dedicated hybrid model cruises into the 2011 model year with several exterior color changes.
The luxurious color palette receives several modifications for 2011 as Satin Cashmere Metallic replaces Golden Almond Metallic, Deep Sea Mica replaces Black Sapphire Pearl, and Aurora White Pearl is discontinued.
Designers and engineers took the opportunity to create a truly unique luxury car that maximizes fuel economy while further shrinking its impact on the planet by using ecologically advanced materials, cleverly packaging people and components, and eradicating waste wherever possible. Outstanding fuel economy is the inevitable result.
Available in standard and Premium models, the HS 250h has a combined EPA-estimated fuel economy rating of 35 mpg combined, 35 mpg city and 34 mpg on the highway utilizing regular 87-octane gasoline – a 74 percent better city mpg rating compared to the average near-luxury sedan.
The HS 250h features the brand’s first four-cylinder gas engine paired with Lexus Hybrid Drive. Utilizing the most recent generation hybrid system, HS 250h takes advantage of the company’s continuous engineering advances to maximize fuel economy, minimize emissions and deliver driving pleasure. A highly efficient engine design, an exhaust heat recovery system, major efforts to reduce parasitic losses, an evaporative emissions system and driver-selectable driving modes all make notable contributions. Significant efforts were also made to minimize engine noise.
An Atkinson-cycle engine design was chosen for its high efficiency and compatibility with hybrid operation in the HS 250h. The twin-cam engine uses four valves per cylinder and Variable Valve Timing with Intelligence (VVT-i) on the intake side. The engine is undersquare, with an 3.48-in. bore diameter and 3.78-in. stroke, and has a relatively high compression ratio of 12.5:1. Peak output equals 147 horsepower and in combination with the hybrid drive motor, the HS 250h generates 187 total system horsepower.
