What is the diff ratio of the GS 450h?
The diff ratio, or differential ratio, of the Lexus GS 450h is a key specification that determines the vehicle's performance and handling characteristics. In this article, we'll dive into the details of the GS 450h's diff ratio and explore how it impacts the driving experience.
What is Diff Ratio?
The diff ratio, or final drive ratio, is the ratio between the number of times the driveshaft rotates compared to the number of times the wheels rotate. This ratio determines the amount of torque delivered to the wheels, affecting the vehicle's acceleration, top speed, and fuel efficiency.
A higher diff ratio, such as 3.727:1, means the wheels will rotate fewer times than the driveshaft, resulting in more torque delivered to the wheels. This provides better acceleration but lower top speed. Conversely, a lower diff ratio, such as 2.937:1, will result in higher top speed but less torque and acceleration.
The GS 450h's Diff Ratio
The Lexus GS 450h, a hybrid luxury sedan, has a diff ratio of 2.937:1. This relatively low ratio is designed to optimize the vehicle's performance and efficiency, balancing acceleration, top speed, and fuel economy.
The GS 450h's hybrid powertrain, which combines a 3.5-liter V6 gasoline engine with an electric motor, benefits from the 2.937:1 diff ratio. The electric motor provides instant torque, while the gasoline engine delivers sustained power at higher speeds. This combination, along with the optimized diff ratio, allows the GS 450h to achieve impressive acceleration and a respectable top speed, all while maintaining good fuel efficiency.
Impacts on Driving Dynamics
The GS 450h's 2.937:1 diff ratio has several impacts on the vehicle's driving dynamics:
- Acceleration: The relatively low diff ratio provides a good balance of acceleration, allowing the GS 450h to reach highway speeds quickly.
- Top Speed: The 2.937:1 ratio enables the GS 450h to achieve a top speed of around 155 mph, making it a capable high-speed cruiser.
- Fuel Efficiency: The optimized diff ratio, combined with the hybrid powertrain, helps the GS 450h achieve impressive fuel economy ratings of up to 29 mpg in the city and 34 mpg on the highway.
- Handling: The low diff ratio contributes to the GS 450h's responsive and agile handling, providing a more engaging driving experience.
Overall, the Lexus GS 450h's 2.937:1 diff ratio is a well-balanced choice that allows the vehicle to deliver a compelling blend of performance, efficiency, and driving dynamics.
