The Lexus Hybrid experience is unlike anything the luxury automotive industry has ever seen. Born from a long history of Lexus hybrid innovation, the Lexus Hybrid Model Line is luxurious, powerful and sustainable. No plug required, the Lexus Hybrid line perfectly blends luxury with the environment and has been doing so longer than any other luxury automaker. Now, with six models to choose from, Lexus is ready to showcase the Power of h.
The Lexus Hybrid, Defined.
The Lexus Hybrid Drive System of today includes an ingenious mechanism that hides behind a driving experience that’s intuitive and just as connected to the road by delivering a natural driving feel that makes you forget you’re in a hybrid. To know the Lexus Hybrid, we should first familiarize ourselves with a few Hybrid terms.
- Hybrid Electric Motor Generator/Engine Starter (MG1): “Small MG” – The MG1 is the smaller of two permanent-magnet AC synchronous motor generators in the hybrid system and is driven by the gasoline engine to create electricity. It also acts as a starter to fire the gasoline engine.
- Hybrid Electric Motor Generator (MG2): “Big MG” – The MG2 is the larger of the two aforementioned motor generators in the hybrid system that powers the drive wheels with electricity which is supplied by the high-voltage hybrid battery. The MG2 also functions as a generator during deceleration or braking to recharge the hybrid vehicle’s battery.
- Motor Generator Rear (MGR): The MGR is used to drive the rear wheels of the all-wheel-drive Lexus Hybrid vehicles. The MGR takes input from the Power Control Unit to produce the appropriate torque and power as needed.
- Hybrid Inverter Assembly with Boost Converter, Inverter, and DC/DC Converter: yes, it’s a mouth-full – The inverter assembly can boost or drop battery voltage, and also convert direct current (DC) into alternating current (AC) and, conversely, AC back into DC.
- Power Management Control Unit: The hybrid power control unit performs comprehensive controls of the Lexus Hybrid System including the electric continuously variable transmission. It takes information from various sensors and electronic control units (ECUs) and outputs the needed torque and power to the Motor Generators. This smart system also monitors the batteries state of charge (SOC) and control the battery cooling blower assemblies.
- Lexus Hybrid Vehicle System Warranty: 8 years/100,000 miles of Lexus coverage on the hybrid components mentioned above.
- Lexus Hybrid Batteries
- High-Voltage Sealed Nickel-Metal Hydride (NiMH) Battery: supplies electric power to (and is recharged by) the Electric Motor Generator (MG1/”little MG”) and Electric Drive Motor (MG2/”Big MG”) in accordance with driving conditions. It is a well-proven, long-life battery that serves as the hybrid system electric energy “fuel tank” and is designed to outlast the life of the vehicle.
- Lithium-Ion Battery: Lightweight, the high-density battery that supplies electric power to (and recharged by) the MG1 and MG2 just like the aforementioned battery.
- Electronically Controlled Continuously Variable Transmission (ECVT): The hybrid vehicle’s transmission that provides a smooth, stepless power to the drive wheels while managing the difference in speed between the gas engine and electric motor while optimizing fuel efficiency.
- Multi-Stage Hybrid Transmission: NEW and a world-first from Lexus that combines the benefits of a conventional ECVT transmission with a gear train composed of two main devices: a Power Split Device and a 4-speed multi-shift device.
- Electronically Controlled Braking-Regeneration System: Found on hybrid vehicles, the system uses braking resistance within the main electric-drive motor/generator (MG2) to slow the vehicle, spin the motor/generator and send electricity back into the HV battery. This hybrid staple benefits both fuel efficiency and driving range while reducing mechanical brake wear.
Lexus Hybrid FAQ’s
Let’s explore FAQ on the Lexus Hybrid Drive system and a few reasons why you should consider a Lexus Hybrid vehicle.
Q: Why do you talk about performance? Isn’t a hybrid just all about fuel economy?
A: Hybrids, like the LC 500h, have the performance of a larger engine with exceptional fuel economy for daily driving. Thanks to the combination of the gas engine and electric motor, the Lexus Hybrid delivers instant low-end torque for quicker 0-30 acceleration. Fast as h.
Q: Do I have to plug in my Lexus hybrid vehicle?
A: No plug required. Lexus Hybrid technology automatically recharges the 12-volt and hybrid batteries using regenerative braking or by running the engine to generate electricity. The power of h.
Q: Do hybrids have a higher cost of ownership?
A: Nope. There is actually a lower anticipated cost of ownership thanks to the elimination of many powertrain components with fewer moving parts and less wear and tear. Not to mention fuel savings.
