Is Lexus GS450h all wheel drive?
The GS450h uses an all-wheel-drive hybrid system (Lexus E-Four). In practice, the petrol engine powers the front wheels while an electric motor drives the rear wheels, giving AWD capability.
Beyond this basic setup, the GS450h combines a 3.5-liter V6 with electric propulsion to deliver balanced performance and traction across a range of road conditions. This article explains how the system works, its benefits and limits, and what drivers should know when shopping for a used GS450h.
How the GS450h's AWD system works
What is E-Four?
The GS450h uses Lexus' Hybrid Drive paired with the E-Four all-wheel-drive system. The front wheels are driven by the gasoline V6, while an electric motor provides rear-wheel torque to add traction when needed. The system is managed by a control unit that optimizes grip and efficiency across conditions.
Key aspects of the E-Four setup include:
- The gasoline engine primarily drives the front wheels.
- A rear electric motor adds torque to the rear axle for all-wheel drive capability.
- Regenerative braking recharges the hybrid battery while slowing the car, aiding efficiency.
- The system can favor front-drive under light loads and engage rear torque during acceleration or in slippery conditions for better traction.
- There is no traditional transfer case; torque distribution is managed through the hybrid transaxle and electric motors.
In daily driving, the system tends to operate seamlessly, delivering AWD without driver intervention. This design provides improved traction in wet or slippery conditions while maintaining the smoothness and efficiency expected from a luxury hybrid.
What it means for driving and fuel economy
Traction, efficiency, and caveats
Drivers typically notice enhanced grip in rain or light snow thanks to the electric rear motor providing rear-wheel torque. The AWD experience on the GS450h is more about traction balance and instant torque than a fixed, mechanical 4WD feel.
Pros and limitations at a glance:
- Improved all-weather traction compared with rear-wheel-drive or some front-wheel-drive hybrids.
- Seamless integration with the hybrid powertrain; no need to activate a separate AWD mode.
- Fuel economy benefits from the hybrid system, though AWD adds weight and complexity that can affect efficiency in some conditions.
- Maintenance costs can be higher due to the additional hybrid components; battery health matters over time.
- Performance and economy vary by model year, trim, and driving style; vehicle software and motor calibration influence feel and response.
Overall, the GS450h’s E-Four AWD system is designed to provide better traction without compromising the quiet, refined experience expected from Lexus’ hybrid lineup.
Model years and market variations
Regional differences and evolution
From its introduction in the late 2000s through the mid-2010s, the GS450h was offered with the all-wheel-drive E-Four system in most markets. Updates during its run refined battery management, software calibration, and motor control to improve responsiveness and emissions compliance.
When evaluating a used GS450h, check the specific market and trim to confirm the AWD configuration, battery health, and software version, as these factors influence how the system behaves in real-world driving.
Summary
The Lexus GS450h is an all-wheel-drive hybrid powered by Lexus’ E-Four system. The front wheels are driven by the 3.5-liter V6 engine, while an electric motor powers the rear wheels to provide traction when needed. This setup aims to deliver improved grip in adverse conditions while preserving the refined efficiency and smoothness of a luxury hybrid. If you’re considering a used GS450h, verify the AWD configuration and battery condition for the best ownership experience.
Is the Lexus GS FWD or RWD?
The GS featured six-cylinder engines and rear-wheel drive, with V8 engines offered for all generations. All-wheel drive and hybrid versions debuted in 2005.
What models of Lexus GS are AWD?
The 2020 Lexus GS comes in just two models: the GS 350 and the GS 350 F Sport. The GS 350 trim level starts out at $51,065 for the standard All-Wheel-Drive (AWD). The GS 350 F Sport starts out at $52,760 for the standard Rear-Wheel-Drive (RWD) version. Both models come in either AWD or RWD versions.
Is the Lexus GS450H front or rear-wheel drive?
rear-wheel drive
The Lexus GS450H was the hybrid variant of the popular Lexus GS series, first introduced in 2005 for the 2007 model year. It was the first mass-produced, rear-wheel drive luxury hybrid car and featured the naturally aspirated 3.5-liter 2GR-FSE V6 engine paired with a continuously variable transmission (CVT).
Are all Lexus 450h all-wheel drive?
LEXUS CROSSOVERS/SMALL SUVS WITH AWD
The larger NX offers a drivetrain choice on its base 300 and 300 F Sport trims, with AWD standard on the hybrid 300h. The RX 350, RX 350L, and RX 350 F Sport present AWD as an option to the standard FWD, but the hybrids, the 450h and 450hL, are AWD only.
