Different Types of Ford Focus: Understanding the Rear Differential

The Ford Focus, a popular compact car model, is typically designed as a front-wheel-drive (FWD) vehicle, meaning that the engine's power is transmitted directly to the front wheels. However, there are specific exceptions where the Focus incorporates additional components to enhance its performance and capabilities. One such component is the rear differential, which is found exclusively in certain versions of the Focus, notably the 2016 Focus RS. This article will delve into the details of the rear differential in Ford Focus models, focusing on front-wheel drive (FWD) and all-wheel drive (AWD) configurations.

Front-Wheel Drive Models: No Rear Differential

Most Ford Focus models, regardless of their trims, are designed as front-wheel-drive vehicles. These vehicles do not require a rear differential because power is not transmitted to the rear wheels. As a result, there is no need for a differential gear to be installed in the rear axles. This design choice simplifies the vehicle's mechanical setup, making it more economical and reliable.

All-Wheel Drive Models: Torque Vectoring Rear Drive Unit (RDU)

One notable exception is the 2016 Ford Focus RS, which is equipped with an advanced all-wheel-drive (AWD) system. Unlike traditional rear differentials, the Focus RS does not use a differential but instead features a Torque Vectoring Rear Drive Unit (RDU). This innovative system utilizes two clutches to independently control power distribution to each rear wheel. By distributing power asymmetrically, the RDU can apply up to 100% of the rear power to a single wheel, providing enhanced traction and dynamic handling.

2016 Ford Focus RS: The Only AWD Model with a Rear Differential

The 2016 Ford Focus RS was the first production civilian-spec Focus model to be equipped with all-wheel-drive capability. This groundbreaking model introduced advanced AWD technology and a rear differential to its mechanical setup. The rear differential in the Focus RS is not a traditional differential but rather an integrated part of the RDU system. This system allows for precise control over power distribution, enhancing both performance and safety during challenging driving conditions.

Conclusion

In summary, the Ford Focus is primarily a front-wheel-drive vehicle, and its standard models do not have a rear differential. However, the 2016 Ford Focus RS is an exception to this rule. It incorporates an innovative Torque Vectoring Rear Drive Unit and a rear differential, making it a unique and technologically advanced variant of the Ford Focus. This focused design ensures exceptional handling, performance, and safety for those seeking a more dynamic driving experience.
