Is purchasing an Audi Quattro worthwhile?
If you’re going to be in any of the following driving circumstances, the answer is yes:
- Winter roads that are consistently snowy and slippery
- towing a campervan or horsebox trailer
- Your employment requires you to go to remote locations, like a rural vet.
- Your neighborhood is steep.
- You prefer to feel your car truly cling to the pavement.
Audi’s “quattro” four-wheel drive is one of the few technologies with which the name is as closely connected. When playing the “association game,” most individuals would often say “quattro” in response to someone saying “Audi,” and vice versa when someone stated “quattro.”
Is quattro the ideal AWD system?
Performance car enthusiasts have long understood that quattro is the best way to enjoy all-wheel drive. Through the middle differential, quattro transfers torque from wheels with little traction to wheels with more traction. This transfer is a seamless process with fantastic outcomes.
Quattro can quickly adapt to changing circumstances. Superior control over practically any surface is the consequence.
Quattro’s most recent improvement, ultra technology, combines this unmatched handling with fuel economy. For better fuel efficiency, the car can transition to front-wheel driving thanks to ultra technology. The car can save an additional 0.3 l/100 km by making this modification.
A dual-clutch technology that enables the rear axle to fully decouple produces this switch. The automobile will only use the front-wheel drive when the driving circumstances are favorable. I doubt this will have an impact on drive quality. When a vehicle needs all-wheel drive, it will virtually instantaneously engage.
It will be nearly imperceptible when you transition from a straightaway to a tight bend or from dry asphalt to ice, but you’ll have better control and traction the entire time. You get all the advantages of AWD with quattro with ultra technology, plus increased fuel economy.
Why is an Audi considered a quattro?
Simply put, Quattro is an Italian word that means “four” and is an Audi registered brand. Audi is known for its famed four-wheel drive technology or system, which delivers the ideal amount of power to each wheel as necessary to produce exceptional handling and grip.
Is quattro still the top vehicle?
For many years, the German auto industry has been on the cutting edge of technology, especially when it comes to all-wheel drive systems for street cars. The competition between Audi and BMW, who have quickly ascended to the top of this particular engineering subculture, is as fierce as ever. It appears that the tide is beginning to shift in favor of the people from Munich as xDrive BMWs are now outselling quattro-equipped Audis in the UK. What distinguishes these all-wheel drive systems, and which is more powerful?
Quattro
In the previous few decades, it’s safe to say that Audi has been a major player in the all-wheel drive industry. Although Subaru’s AWD systems may have been technically more sophisticated, Germans have been commercializing power distribution to all four wheels for the general public ever since the coveted Audi ur-quattro of the early 1980s.
Audi introduced its all-wheel drive system to rallying at a time when rear-wheel drive was prevalent and totally transformed the motorsport.
Since then, Quattro has developed and is now prominently displayed on the front grille and rear bumper of numerous Audi vehicles. When driving normally, the two axles are split 50:50, forming a balanced all-wheel drive system. In the S and RS variants, that orientation shifts more in favor of the rear. It makes use of an internal gearbox-built central Torsen (torque sensing) differential. Comparing it to the transfer boxes formerly utilized in off-roaders, it is a lovely, tidy compact.
“True” quattro systems are installed longitudinally, parallel to the car’s engine and gearbox. The A3 and TT are transverse-engined vehicles, hence a complete quattro system cannot be installed beneath the hood. Instead, the smaller-engined vehicles employ a Haldex four-wheel drive system, which is typically front-wheel drive until more traction is needed from the rear wheels.
With stability control and simply mechanical torque transfer between the two axles, the Torsen diff enables each wheel to spin at a different speed based on the slippage circumstances at each curve. The center differential locks and torque is transferred from the axle with slippage to the other axle with traction when a wheel slides on one of the axles (one driveshaft rotates faster than the other). When the wheel slip is no longer there, the diff unlocks, and the torque bias returns to normal.
xDrive
In this area, BMW has had to catch up to Audi, but some would argue that the Bavarian AWD system is more than capable of competing with quattro’s rally-derived power. The E30 325iX ‘Allrad’ from 1985 was the first BMW to use all-wheel drive, but now the company’s own AWD technology is available in everything from the affordable 1-series to the opulent 7-series.
As opposed to the viscous coupling seen in many other generic all-wheel drive vehicles, xDrive utilizes a multiplate clutch arrangement. With the potential to transfer 100% of the torque to one axle, output is electronically controlled utilizing the clutch system to adjust torque to the axles every 0.1 seconds. By braking the inside wheels and reducing power across the axles to improve rotation of the vehicle, dynamic stability control works in conjunction with an xDrive system to improve the on-road capabilities.
As expected, xDrive is a rear-biased system with a 40:60 distribution between the front and rear, as decided by BMW. The corporation has stuck to its tenet and decided that its AWD cars must still feel and behave like authentic BMWs on the road, despite the fact that this may appear to be detrimental to AWD performance since less torque is being applied in the position of the big engine for traction.
Which one is superior? It depends on whom you ask, as there are numerous videos and forum discussions about which is better. Due to the fierce competition, it is difficult to believe any DIY comparison videos because any bias in favor of one side or the other immediately taints the results. The likelihood of a fair outcome being achieved is frequently destroyed by accusations of tampering with stability control settings and sloppy driving.
Since the compounds would need to be comparable in composition and wear to do a proper test, the tires are a significant component as well. This adds to the long list of variables.
Quattro all-wheel drive is a pretty straightforward system because it is entirely mechanical, but Audi has found great success with it ever since it dominated the rally circuit in the 1980s.
But in some circumstances, a Quattro automobile may suffer because of the locking differentials. In its simplest form, Quattro cannot fully lock an axle like the BMW can since some torque output constantly reaches both. Due to the mechanical design of the Torsen differential, if an axle has no traction, there will be no resistance transferred to the opposite side of the car. Since the center differential practically multiplies torque, quattro may run into serious difficulties if all traction is lost at one axle.
The engine had to be placed higher up the chassis due to the packaging space requirements for the quattro system. Due to the front-heavy weight distribution caused by this, quattro cars have come to be associated with understeer, a problem that has plagued Audis for decades. However, generally, it is still a very capable AWD system that has repeatedly demonstrated its ability to handle the most challenging real-world driving circumstances.
XDrive has its advantages and might be considered the more sophisticated technology because it responds to inputs electrically much more quickly than a hydraulic viscous coupling. The ability to send all of the torque to one axle thanks to the electronically-actuated clutch offers a BMW an edge when switching from a surface with strong traction to one with low traction, or vice versa.
However, xDrive’s electrical component results in some undesirable interference when compared to Audi’s mechanical system. The Audi should theoretically be superior while attempting to make quick progress on a snowy or icy road because of the rear-bias, which causes the electronics to always veer towards safety.
You could say that Ingolstadt has given in to Munich’s way of thinking because Audi recently began the transition to electronics with its “Ultra quattro” line, which employs an actuated clutch similar to BMW. Audi appears to have evaluated the Haldex system’s popularity and determined that it’s time to relegate the torsen diff to the past after debuting it in the 2016 A4 Allroad estate.
It remains to be seen whether Audi will fully follow that line of reasoning, but choosing between McDonald’s and Burger King when it comes to all-wheel drive systems is a similar proposition. They work exceedingly well, but in slightly different ways, each with advantages and disadvantages. However, if you prefer rear-wheel drive fun and won’t be driving on any snow-covered roads any time soon, the xDrive system will probably come out on top in this comparison.
Is quattro more rapid?
We are aware that quattro denotes four-wheel drive.
Quattro does certainly translate to “four” in Italian, but why is this even a positive thing? Ask an automotive expert, and you’ll likely receive a fairly complex set of explanations, but it’s simpler to concentrate on the forces acting on the tyres of your automobile as they grip the pavement.
Depending on whether an automobile has front- or rear-wheel drive, all of the power is transferred to the front or back wheels. All four tires receive drive in a car with all-wheel drive or quattro. In turn, the tyres of a quattro-spec Audi will offer more grip than a two-wheel drive vehicle, whether you’re accelerating or cornering.
If you enter a wet roundabout a little bit faster than is prudent, this has apparent safety repercussions because you have more leeway before the car starts to skid. Additionally, many Audi owners opt for quattro if they commute in isolated or high-altitude regions of the country where snow and icy conditions are more frequent or if they reside in the country where the roads are frequently muddy.
The same maximization of traction rule applies to quattro performance vehicles, which can accelerate and turn more quickly due to the extra grip that comes from having all four wheels operated.
Since Audi also sells quattro Q3, Q5, and Q7 models, quattro SUVs and off-road vehicles should also be mentioned. Another benefit is the added grip, which is important for anyone traveling off-road on mud or gravel paths. Quattro is also advantageous for towing because you’re less likely to lose traction.
Audi Quattro or BMW xDrive: which is superior?
Audi was a leader in all-wheel drive for performance driving in the early 1980s. Although it wasn’t the first all-wheel drive vehicle, the Quattro technology made it the first to become known for street-driving sports cars. Soon after, BMW made the decision to introduce xDrive, its own all-wheel drive system. The two automakers have been competing against one another with their own all-wheel drive cars since the 1980s, but never more so than currently.
Since it’s now nearly impossible to find a BMW without xDrive all-wheel drive, the two companies are now more competitive than ever. So let’s compare the all-wheel drive systems of the two companies to determine which one you ought to pick.
BMW xDrive
The xDrive all-wheel drive technology from BMW is straightforward but efficient. BMW’s xDrive system functions in essence as follows: wheel speed sensors monitor wheel slip in conjunction with DSC (Dynamic Stability Control), and if it detects that a particular wheel is slipping, an electronically controlled multi-plate clutch connected to the transmission will route power to the appropriate axle.
In typical driving situations, the front wheels receive 40% of the engine’s power, while the rear wheels receive 60%. Theoretically, either axle might get up to 100% of the power. Modern xDrive systems, like the one in the new BMW M3, may transfer power to whichever axle is performing at its optimum at any given moment.
The benefits of BMW’s xDrive include that it can, if necessary, transfer all of the vehicle’s power to either axle and that its wheel speed sensors can precisely fine-tune the amount of power at each axle. Additionally, the system is quite cheap, easy to package, and lightweight.
Audi Quattro
The current state of Audi’s all-wheel drive systems can be a little unclear. There are actually two distinct Audi “Quattro systems, but only one of them is a true Quattro, just like the one found on the storied Quattro rally car. Engines are longitudinally positioned in proper Quattro systems, and Torsen center differentials are built into the transmission’s rear. Under typical driving circumstances, the mechanical center diff distributes 40% of the engine’s power to the front axle and 60% to the rear axle.
However, the center diff locks up and transfers power to the opposing axle when one axle begins to slip, speeding up that axle’s driveshaft. Depending on the situation, modern Quattro systems can distribute up to 85% of the engine’s power to the back axle and up to 70% to the front axle. Since Quattro-equipped Audis are properly rear-biased, BMW aficionados who ridicule Audis for being front-biased are mistaken.
The advantages of Quattro are many. One is that it instantly distributes mechanical power without the assistance of electronics. A Torsen differential is also more dependable, durable, and reliable than a clutch pack since it is much more robust. In adverse weather circumstances, Quattro outperforms the majority of alternative all-wheel drive systems due to its quick and continuous power delivery to the required axle, as well as its durability.
Audi’s Quattro, however, also has a few drawbacks in addition to its many advantages. One is that, as the flip side of its durability, it is rather heavy. Additionally, it makes the entire powertrain longer and more difficult to package, which is why Audis are always so front-heavy with their engines slung quite far out in front of the front axle. Additionally, it cannot supply one axle with all of the engine’s power since both axles must get some power.
Conclusion
Both approaches are really effective and, in all honesty, each has its advantages. Both systems have been used by us quite a bit, and we have always been impressed by how well they function. I’m not sure if one is much superior to the other, but they both have advantages.
My extensive driving of both of them has led me to believe that the BMW xDrive is superior for performance handling on dry tarmac while the Audi Quattro excels in inclement weather. However, both perform admirably in practically any circumstance, demonstrating how far all-wheel drive technology has advanced.
