What is Lexus hybrid drive , Basically Lexus Hybrid Drive is the same technology as Toyota Hybrid Synergy Drive. Lexus is a luxury brand owned by Toyota, and their vehicles benefit from Toyota’s hybrid expertise.
Types of Lexus Hybrid Drive vehicle
- HEV Model : This is the most common type of Lexus hybrid. It uses a combination of a gasoline engine and Two electric motor generator Or Three Motor generator for AWD to power the car
- PHEV Model: Lexus PHEV offers more electric driving range than an HEV. It has a larger battery pack that can be plugged into an external power source to charge.
- 1Motor Generator-HEV Model
Quick table summarizing the key differences
| Feature | HEV Model | PHEV Model | 1 Motor Generator-HEV |
|---|---|---|---|
| Primary Power Source | Gasoline Engine | Gasoline Engine + Plug-in Charging | Gasoline Engine |
| Electric Driving Range | Limited | Longer | Limited |
| Battery Size | Smaller | Larger | Similar to HEV |
| Number of Motor Generators | Two (MG1 & MG2) Three (MG1, MG2 & MGR)(AWD) | One (MG) | One (MG) |

Lexus Hybrid Drive Operation
Start up and driving off-
- Powerful front and rear electric motors can propel the vehicle up to 65 km/h
- Vehicle is almost silent, uses no petrol, and produces zero emissions during this phase
Normal condition in hybrid system?
- Above 65 km/h, V6 petrol engine cuts in quietly with assistance from electric motors
- System distributes petrol and electric power sources for driving enjoyment, low emissions, and fuel efficiency
On full throttle acceleration
- Electric motors instantly supplement the 3.5-litre petrol engine
- Together they deliver a potent surge of torque for breathtakingly fast linear acceleration
DECELERATION, STOPPING, BRAKING
- During deceleration or stopping, petrol engine turns off, cutting emissions to zero
- Regenerative braking harnesses kinetic energy lost in other cars
- Converts this energy into electrical energy stored in the hybrid battery
- This means the hybrid never needs plugging in to recharge
