Under the hood of the luxurious hybrid lies a 3.5-liter V6 Atkinson-cycle engine which is accompanied by several fuel-saving innovations such as electric motors and a small and light power-control unit. With 295 horsepower, the powerful vehicle offers better fuel economy than many typical four-cylinder mid-size sedans.

To help provide the best fuel economy possible for Chantilly Lexus drivers, the vehicle employs an exhaust heart-recovery system that circulates engine coolant through a unit installed in the exhaust pipe, further reducing engine warm-up time. This allows the vehicle to stop earlier for more frequent, longer spans of time, ultimately enhancing fuel economy and emissions. Drivers can expect an EPA-estimated fuel economy of 32 miles per gallon in the city with the Front Wheel Drive model, and 30 miles per gallon with the All Wheel Drive.

With utilization of a engineering marvel the Atkinson cycle, the hybrid’s engine’s intake valves are delayed to make for a larger expansion ratio. This cuts down on intake and exhaust energy, creating a more efficient combustion and even better fuel economy. The Atkinson cycle also decreases the engine’s exhaust temperature that further improves fuel economy by eliminating fuel enrichment that would typically be needed to prevent any overheating.

With the Atkinson cycle, the gasoline engine’s intake valves are closed late to delay beginning of compression, resulting in a higher expansion ratio. That reduces intake and exhaust energy losses for more efficient combustion and improved fuel economy. The gas engine alone produces 245 horsepower at 6,000 rpm and 234 lb.-ft. torque at 4,800 rpm. The Atkinson cycle also reduces exhaust temperature.

A cooled Exhaust Gas Recirculation (EGR) system reduces it further still, helping economy by eliminating the fuel enrichment otherwise needed to help prevent catalyst overheating under high loads.

Besides just the powertrain, the Lexus RX 450h houses a host of other “green” elements. The power-steering pump, water pump and air-conditioning compressor are all powered by electricity rather than the engine. Chantilly Lexus shoppers will also find Intelligent Adaptive Front-lighting System (AFS) for high beams in HID headlamp models, and for low beams in the LED equipped models. When the vehicle approaches a corner, Adaptive Front-lighting system estimates where the vehicle will be, which is determined by the vehicle speed and the angle of the tires. It then adjusts the lateral aim of the headlamps. Drivers can opt to shut of this system, which also comes with auto-leveling function.
