What is the diff ratio for a 2.0 Ford Cortina?
The diff ratio, or differential ratio, of a 2.0 Ford Cortina refers to the gear ratio between the vehicle's drive shaft and its rear axle. This ratio determines the amount of torque and speed delivered to the wheels, affecting the car's overall performance and fuel efficiency.
Understanding Diff Ratio
The diff ratio is a crucial specification for any vehicle, as it determines the balance between torque and speed. A higher diff ratio, such as 3.55:1, will provide more torque to the wheels, making the car feel more powerful and responsive, but at the expense of fuel efficiency and top speed. Conversely, a lower diff ratio, such as 2.73:1, will result in better fuel economy and higher top speeds, but with less low-end torque.
The Diff Ratio for a 2.0 Ford Cortina
The 2.0-liter Ford Cortina, a popular mid-sized car produced from the 1960s to the 1980s, typically had a diff ratio of around 3.31:1. This means that for every one revolution of the drive shaft, the rear wheels would rotate 3.31 times.
The 3.31:1 diff ratio was a common choice for the 2.0 Cortina, as it provided a good balance between performance and fuel efficiency. This ratio allowed the car to accelerate reasonably well while still maintaining decent fuel economy on the highway.
Factors Affecting Diff Ratio
- Engine displacement: Larger engines typically require higher diff ratios to deliver sufficient torque.
- Intended use: Vehicles designed for towing or off-road use often have higher diff ratios for increased low-end torque.
- Transmission type: Manual transmissions may have different diff ratios than automatic transmissions in the same vehicle model.
- Wheel and tire size: Larger wheels and tires can affect the optimal diff ratio for a given vehicle.
The 3.31:1 diff ratio was a well-suited choice for the 2.0 Ford Cortina, providing a balance of performance and efficiency that made it a popular choice among drivers of the time.

Will the VIN number tell me the gear ratio?
You don't. That information is not contained in the VIN, UNLESS a specific model only gets one rear end ratio. VIN tells country of manufacture, vehicle make, class, engine type, size, date of manufacture, plant and serial number. That is the ONLY information contained by the VIN.
What is a 3.73 gear ratio good for?
For a truck, it is great for heavier loads where factory gear ratios that are 3.55 or 3.31. In a sports car, 3.73 gears will offer better acceleration while retaining top speed when compared to 3.55 gears that come factory on many sports cars.
What ratio is the Ford 8.8 final drive?
The 8.8 was built with the following ratios: 2.26, 2.47, 2.73, 3.08, 3.27, 3.45, 3.55, 3.73 and 4.10:1. Only the 2.73, 3.08, 3.27, and 3.55:1 ratios were available with Traction-Lok. If you decide to upgrade to a Traction-Lok differential, you're limited to the ratios offered at the factory.
What is Ford's quick ratio?
It is calculated as a company's Total Current Assets excludes Total Inventories divides by its Total Current Liabilities. Ford Motor Co's quick ratio for the quarter that ended in Sep. 2024 was 0.98. Ford Motor Co has a quick ratio of 0.98.
What diff ratio is faster?
A lower ratio gives better fuel economy but slower acceleration, while a higher ratio provides quicker acceleration but lower fuel economy. This number helps you understand a vehicle's performance and choose the best option for your driving needs.
Why is the Ford 8.8 rear end so popular?
And Broncos especially the four-wheel drive models and those with bigger engines. But not always because mine's a 300. And it's got an 8.8.
What is the best rear ratio?
For High-Performance Cars: Ratios like 4.10 to 4.30 are common. For Street Cars: Ratios around 3.73 to 4.10 can provide a balance between performance and drivability. Ultimately, finding the optimal ratio often requires testing and tuning based on your specific vehicle setup and performance goals.
How do I find my Ford axle ratio?
To determine the axle ratio of your vehicle, locate the two-digit axle code first, then use your vehicle's towing guide to find the axle ratio that corresponds to that code. If your vehicle has a limited-slip differential, it will be noted as Limited Slip.
How do I identify my Ford rear differential?
The most accurate differential identification is provided by the bottom line of the tag number or axle tube stamp. Differential tags can easily be used to identify Dana and Ford differentials.
