Lexus unveiled today at the Detroit Auto Show world’s first ever dedicated luxury hybrid vehicle: the HS 250h, the fourth hybrid and the most fuel-efficient vehicle in its lineup. Sales will begin later in the summer.
The HS 250s is powered by Lexus’ first four-cylinder gas engine: the 2.4-liter Atkinson-cycle that develops 187 hp. The highly efficient Atkinson-cycle engine, made possible by the Variable Valve Timing with intelligence (VVT-i) system, allows the expansion/power stroke to be longer than the compression stroke so that combustion energy can be more effectively used for production of engine power
