How does the hybrid system of the Lexus RX 450h 2021 work?

The 2021 Lexus RX 450h is a unique model in its segment. It features a traditional 308-horsepower hybrid engine making it the most powerful model in the RX lineup, but its fuel mileage is more like that of a mid-size car than an SUV.

Offered in a regular wheelbase version or in an L extended wheelbase version, the Lexus RX 450h offers a great level of luxury while being very fuel efficient. It also offers the same cargo capacity as the RX 350 with an internal combustion engine. Unlike some of its rivals, you don't have to plug in or charge the Lexus RX 450h to take advantage of its electric motors and the fuel economy that comes with it. Let's take a closer look at how this engine works.

Lexus RX 450h Hybrid System Overview

The Lexus RX 450h offers a hybrid system that dramatically improves fuel economy without requiring the driver to adjust his or her behaviour behind the wheel. The hybrid system of the RX 450h combines a traditional gasoline engine with an electric drive.

Concretely, it is a version of the Toyota/Lexus Hybrid Synergy Drive system that combines the gasoline engine and two electric motors that work in tandem to propel the vehicle. In other words, the RX 450h can switch from internal combustion to electric operation depending on driving and conditions or use both types of propulsion when necessary.

At low speed, the system can only use electric motors and operate in 100% electric mode. When we accelerate or drive at higher speeds, then both types of engines come into play.

The main takeaways from this system:

- You do not have to adapt your driving

- You will not notice any difference in efficiency compared to a traditional motor

- The performance is impressive since three motors help propel the vehicle

- The gasoline engine is helped by electric motors so that it consumes less fuel

- You do not have to recharge your Lexus RX 450h to benefit from the advantages of the electric motor

- Average consumption is set at 7.5 liters per 100 kilometers in the city and 8.4 liters per 100 kilometers on the motorway

The 2021 Lexus RX 450h offers all the comfort and luxury that Lexus has accustomed us to, but it also offers a more efficient and refined drive thanks to the silence of the hybrid powertrain.
