What is the final drive ratio of the Lexus gs300?
The final drive ratio of the Lexus GS300 is 3.727:1. This means that for every 3.727 rotations of the engine, the rear wheels will rotate once. The final drive ratio is an important specification that affects the vehicle's acceleration, top speed, and fuel efficiency.
Understanding the Final Drive Ratio
The final drive ratio is a key component of a vehicle's drivetrain. It determines the relationship between the engine's rotational speed and the speed of the wheels. A higher final drive ratio, such as 4.10:1, will result in faster acceleration but lower top speed and fuel efficiency. A lower final drive ratio, like 3.727:1, will provide a better balance between acceleration, top speed, and fuel economy.
The final drive ratio is calculated by dividing the number of teeth on the ring gear (in the differential) by the number of teeth on the pinion gear. This ratio determines how much the engine's rotational speed is reduced before it reaches the wheels.
The Lexus GS300's Final Drive Ratio
The Lexus GS300, a mid-size luxury sedan, has a final drive ratio of 3.727:1. This ratio was chosen by Lexus engineers to provide a good balance of performance and efficiency for the GS300's target market and driving conditions.
With a 3.727:1 final drive ratio, the Lexus GS300 is able to achieve a top speed of around 143 mph while still providing respectable acceleration and fuel economy. The ratio is a compromise between the need for brisk acceleration from a stop and the desire for efficient high-speed cruising.
Factors Affecting Final Drive Ratio Selection
The selection of a final drive ratio for a vehicle like the Lexus GS300 involves considering several factors, including:
- Engine power and torque: Higher-powered engines may benefit from a lower final drive ratio to take advantage of the engine's torque curve.
- Intended use and driving conditions: Vehicles designed for city driving may have a higher final drive ratio for better low-speed acceleration, while highway-focused vehicles may have a lower ratio for improved fuel efficiency and top speed.
- Transmission type: Vehicles with automatic transmissions may have a different final drive ratio than those with manual transmissions to optimize performance and efficiency.
- Tire size: Larger tires will effectively reduce the final drive ratio, so the ratio may be adjusted to compensate for this.
By carefully selecting the final drive ratio, automakers like Lexus can create vehicles that deliver a compelling balance of performance, efficiency, and drivability for their target customers.
What is the final drive ratio of the gs350?
The GS 350 with 6-speed uses a Final Drive Gear of 3.615. The GS 350 with 8-speed uses a Final Drive Gear of 2.937.
How many miles do 2JZ engines last?
If the 2JZ isn't screwed with they've been proven to last for 200k+ miles time and time again. They're super popular for the tuner market because they are massively overbuilt so they can handle a ton of extra power. I daily drove my SC for years and the only issues I had were electrical and never had an engine fault.
What year Lexus GS is most reliable?
The 2013 Lexus GS is certainly one of the most reliable and often considered the best year Lexus GS when it comes to interior comfort for those long Johns Creek drives. The most significant changes were the 2016 model having a revamped design and being equipped with a new engine option.
What is the rear end diff ratio?
Its the ratio between the driveshaft (input to differential) and axles (output of differential. A 4.11 refers to a 4.11:1 ratio. This means that the driveshaft turns 4.11 times for each time the axles turn once.

Can you change the final drive ratio?
And changing an entire gearbox can be prohibitively expensive. But if you want better acceleration (or more top speed), there is an easier solution to your problem: Change your final drive ratio. The gears within your transmission aren't the only gears in a car.
Are 3.73 or 4.10 gears better?
What Gear Ratio Is Best For Torque? Typically, the shorter the gear, the higher the torque. When looking at 3.73 vs 4.10 gears, 4.10 gears are going to offer higher torque.
Is the Lexus GS300 2JZ reliable?
most reliable car engine you can have
The GS300 has the glorified 2JZ inline 6 cylinder engine. It will last you as long as you want if you are smart. Currently driving one with over 310,000 miles and commonly run into 2JZ owners with even more and still going strong.
What is the diff ratio for a 1998 Lexus GS300?
1998-2005 Lexus GS300 Rear Axle Differential Carrier Assembly 3.92 Ratio OEM.
What is a good final drive ratio?
To find the ideal selection, multiply the final drive ratio by the redline speed in fourth gear (152 mph) and divide that by the top track speed (140 mph). This would yield a theoretical 3.33—which is close enough to the nearest available final drive ratio of 3.36:1.
