The Lexus HS 250h 2009-2012 is a hybrid luxury sedan that combines an internal combustion engine (ICE) with an electric motor to provide an efficient and powerful driving experience. Here's a breakdown of the powertrain details:
Battery Pack
Modules: 34
Nominal Voltage per Module: 7.2 volts
Total Nominal Voltage: 244.8 volts
Type: Nickel-Metal Hydride (NiMH) Prismatic NiMH Battery NP2.0
Manufacturer: Panasonic/Primearth EV Energy Co., Ltd. (4)
Overall dimensions: 32" x 18" x 13"
Weight 105lbs
Internal Combustion Engine (ICE)
Type: 2.4-liter Atkinson-cycle four-cylinder
Power output: 147 horsepower
Features: Twin-cam design, four valves per cylinder, Variable Valve Timing with Intelligence (VVT-i)
Electric Motor
Power output: 141 horsepower
Function: Serves as both a drive motor and a generator
Combined System Output
Total system horsepower: 187 hp
It's important to note that the total system horsepower is not simply the sum of the ICE and electric motor outputs. This is because the two power sources cannot be maximized in the same operational range.
Hybrid System Details
The HS 250h utilizes a two-motor hybrid system:
1. The main drive motor (141 hp) that works in conjunction with the gasoline engine
2. A second motor that functions as both an engine starter and generator to charge the hybrid battery pack
The system employs an Electronically Controlled Continuously Variable Transmission (ECVT) for smooth and efficient power delivery.
Performance
The combination of the ICE and electric motor provides the HS 250h with
0-60 mph acceleration: 8.4 seconds
EPA fuel economy estimate: 35 mpg combined
Driving Modes
The HS 250h offers four selectable driving modes:
1. Normal: Balanced performance and efficiency
2. Power: Enhanced responsiveness
3. Eco: Optimized for fuel economy
4. EV: Allows for short-distance electric-only driving under certain conditions
This hybrid system demonstrates Lexus's commitment to combining luxury with efficiency, offering a sophisticated blend of gasoline and electric power in a premium sedan package.
