A drive system that distributes power evenly among the wheels for dynamic handling, greater safety, and superior distribution. In order to provide excellent traction and completely eliminate understeer, sport differential transfers torque from the engine between the rear wheels.
Driving on rails is one thing, but this is another. As a result, the driver has more control and is safer thanks to the Audi quattro with sport differential system, which distributes power between the rear wheels for optimal distribution and dynamic handling. Sport differential evenly distributes torque to all four rear wheels to maximize traction and completely eliminate understeer.

The number of differentials in a Quattro?
A differential is a group of gears that drives the axle’s wheels. Three differentialsone each in the front, rear, and centerwere part of the original Quattro system, which improved torque distribution to each wheel. The differentials are not closed because separate wheels might spin at different rates. In this manner, the outside wheels of the vehicle can revolve more quickly than the inside ones when it turns.
The front wheels need to turn, hence the differential normally has no lock. The wheels will spin simultaneously to find grip even if one is off the ground, though, if a differential with the capacity to lock is included, such as in the back. Consequently, slippery conditions will have more traction. A driver-operated switch was also included in the original Audi system, allowing the center differential to lock both the front and rear differentials.
Within a decade, a torque-sensing (Torsen) center differential was installed. Automatically, the front and rear axles received an equal distribution of power. The system’s gears were designed to redistribute torque to the axle that required it the most when wheel slide occurred. Up to two thirds of the vehicle’s torque is sent to the front or rear axles using the Torsen differential. Although some larger vehicles also gained a rear Torsen differential for added control, the rear locking differential switch remained functional.
What does Audi’s S line mean?
The highest-spec trim, Audi S-Line, is available for all models, from the A1 to the A8, and it adds a variety of additional amenities.
What makes Audi Quattro superior?
With driver confidence and active safety, quattro provides motorists with a number of benefits over a conventional all-wheel drive system. On a range of driving surfaces, drivers are aware that all four wheels will consistently deliver trustworthy traction: windy circumstances. seasonal precipitation (sleet, snow, hail)
Quattro has 4WD or AWD.
The trademark quattro, which translates to “four” in Italian, is used by the car manufacturer Audi to designate the usage of all-wheel drive (AWD) systems or technologies on particular types of their vehicles.

The German automaker Volkswagen Group’s subsidiary Audi AG owns the registered trademark “quattro.”

The permanent four-wheel drive Audi Quattro model, often known as the Ur-Quattro, was the vehicle that originally featured Quattro in 1980. (meaning “original” or “first”). All following Audi AWD models have been referred to as “quattro” since then. In honor of its former namesake, the term “quattro” is now usually spelt with a lower case “q” thanks to nomenclature rights obtained from the trademark.
What is a differential active?
The active differential, which is very similar to a limited slip differential, still uses mechanisms to provide the resistance needed to transfer torque from one side to the other, but these clutches can be electronically actuated rather than relying just on mechanical force.
Through varying driving circumstances, the active differential can artificially adjust the mechanical forces the system is subject to. By using a variety of sensors all throughout the car, a computer can automatically determine which drive wheels to transmit power to and when, making them controlled and thus programmable.
The rally drivers who drive their cars in constantly changing driving conditions and require a system that can keep up with their constant adjustments to the vehicle favor this since it significantly enhances performance, especially over uneven road surfaces.
Torque Vectoring Differential:
The TVD improves cornering performance by using an electrically upgraded system to control the angle, or vector, of the vehicle entering and exiting corners by inducing particular wheels to experience higher torque at crucial moments.
In order to overcome the shortcomings of the LSD system, you can use the effect to assist with steering while simultaneously applying extra power by engaging the opposite clutch to what a solely mechanically driven LSD would normally engage.
A multi-way LSD applies resistance to both wheels as the car approaches the corner to at least partially lock the axle and stabilize it during braking. As the wheel speed reduces and the vehicle turns in, the resistance is released, enabling the wheels to rotate at separate rates.
However, a TVD continues to engage the clutch on the outside wheel only, increasing the resistance felt by that wheel and causing the system to direct more torque through it. This prevents the resistance from being released on both wheels. The vehicle is encouraged to turn into the bend more sharply and less understeers as a result of the imbalance of power to the outside.
A normal multiway-LSD would once more interpret the faster-moving outside wheel as slipping and divert torque during acceleration to the inside wheel, which it perceives as having more grip, if the driver continued to apply this resistance through the corner. This would override the normal multiway-LSD.
The outside wheels clutch is tricked into receiving more torque by the TVD’s increased resistance, which raises the amount of power that can be applied and lessens understeer when accelerating out of a turn.
The outside wheel’s artificial resistance from the TVD is highlighted by the yellow arrow as it transfers torque through the corner. As a result, the car’s turning capability is improved and acceleration out of the corner is increased.
In the worst-case scenarios, a torque vectoring differential has the ability to direct all of the available torque into a single wheel.
The system’s disadvantages include its high cost and complexity, which limit its use to racing and track applications where high speed cornering is required.
Every system has its own advantages and disadvantages, and while more complex systems are generally better, they come at a cost that is far higher than that of simpler systems.
How much of a benefit you receive from each system depends, as with everything automotive, on what you want to use your car for and what your differential needs to be able to handle. Unless you plan to compete in the next WRC and can pay the fines, you won’t need a torque vectoring differential when you go to the grocery store. However, if you live in a rural area that is accessible only by off-road vehicle, you could require a locking differential.
Is sport superior to S-Line?
If you choose the S Line grade for your new Audi, you’ll get an aggressive bodykit, improved interior design, and lowered suspension for a more thrilling driving experience. Although S Line cars still feature the usual Audi range of engines, they won’t be any faster than the standard car. Instead, they will feel significantly livelier to drive.
Is Black Edition an improvement over S-Line?
You’ve heard the saying “all shirt, no pants,” right? Well, when you possess an Audi S series, you’ll encounter accusations of that nature. Although it appears fast, it is actually no faster than a standard vehicle with the same engine.
The 40 TDI diesel we discussed earlierthe one that achieves fuel economy of more than 50 mpgdoes trade off performance for fuel efficiency. It accelerates to 62 mph in 8.1 seconds, which is three seconds slower than the S6 diesel and twice as long as the 600 PS RS6.
While S line models have reduced suspension, they lack the quattro all-wheel drive found on S and RS models as well as the smart differentials and sizable brakes that make these sportier variants so capable on a winding country road.
Sport is indicated by the S (in the Audi S range). The line simply states that it is a trim level as opposed to the speedier S versions.
The exterior of Black Edition automobiles is matte black rather than chrome, as suggested by the name, which retains the sporty appearance of S line cars.
For greater efficiency, fuel can be squirted straight into the cylinder using TFSI, which stands for turbo fuel stratified injection. By taking the heat out of the intake air, the fuel cools the cylinder, increasing the compression ratio. According to reports, this will increase fuel efficiency by 15%.
On an Audi, what does TFSI stand for?
The turbo fuel stratified injection engine is Audi’s most often used engine (TFSI). When gasoline is pressure-injected into the engine’s combustion chamber to provide an immediate charge, this is referred to as the turbo aspect.
The TFSI engines’ direct fuel injection combined with turbo or supercharging technology results in a powerful ride while using up to 15% less gasoline than a V6 engine.
So how does it function? Direct fuel injection improves efficiency and responsiveness by eliminating heat from the intake air, which raises compression and eliminates knock.
Is BMW superior to Audi?
BMW’s vehicles, which are made to provide the “ultimate driving experience,” frequently outperform Audi in terms of handling. Because of their overall stronger suspension systems that promote a smooth, pleasant ride, Audi vehicles are significantly less agile than BMW vehicles. BMW is routinely ranked higher for reliability.
