The details and discussions about used Lexus RX 450h hybrid for sale are available online and offline since long, one only need to fetch the free knowledge about this vehicle. To be precise, let have an overview about the hybrid tech that is the crux of this variant.
Principle That Drives Hybrid Technology
The principle that drives hybrid technology is linked to the exploitation of the potential of an electric motor combined with the classic thermal engine: it is precise during the phases of greater mechanical stress, and therefore also of higher consumption, that the electric part's intervention produces the output to ensure and control the flawless departures from standstill, queues, accelerations and all the phases that clearly affect the consumption of the car. Let's begin to analyze the most basic, called "Micro Hybrid”: in addition to the possible Stop & Start system, the car is able to recover part of the energy resulting from braking to then use it for secondary services and limit consumption and CO2 emissions. In reality, this architecture is not a true hybrid because the energy recovered is not re-used when the vehicle is pulled.
The Parallel Variant
Then there is the "Mild Hybrid" system, with the further division between "parallel" or "in series". The parallel variant, compared to the Micro Hybrid seen above, adds the possibility of having the electric motor support during the acceleration phases but, normally, not to proceed in electric-only mode. The energy is taken from a battery that is charged by regenerative braking or thanks to the action of the heat engine. The Mild Hybrid in series is instead linked to the electric drive generated by the action of the thermal engine (it is the propeller that charges the batteries, in addition to the regenerative braking).
The last variant, more complex but also more efficient, is the "Full Hybrid" (Toyota and Lexus standard): the car can have traction from the electric motor, from the thermal engine or from both. Normally, at start-up and at low speeds, the use of the electric part is preferred, with zero consumption and CO2 emissions. Above a certain speed or in the event of violent acceleration, the thermal engine also operates, which has the dual task of supplying power and recharging the battery (regenerative braking always remains the primary type of recharge).
The Lexus and Hybrid
The transition to the RX450h marked a new, albeit small increase in the overall dimensions of the car, both in terms of total length and pitch. The lines are more geometric and modern, both interiorly and posteriorly; the front grille becomes wider and the front headlights take on a more cut and incisive shape. Even at the rear, optical groups with a more streamlined trend and with the proportions of the front ones. The excellent news is, you can buy this vehicle at lower Lexus Rx 450h hybrid price via used car exporter.
