Audi quattro: All-Wheel Drive Technology Explained
Since its introduction in 1980, Audi's quattro all-wheel-drive system has become one of the most respected drivetrain technologies in the automotive world. But what exactly is quattro, and why should it influence your next car purchase?
The History of quattro
Audi developed quattro technology for rallying, and its competitive debut at the 1981 Monte Carlo Rally changed motorsport forever. The idea of sending power to all four wheels in a high-performance car was revolutionary at the time, and Audi's success on the rally stages proved the concept comprehensively. Since then, quattro technology has been fitted to millions of road cars and has evolved through multiple generations.
How Modern quattro Works
Today's quattro systems use different approaches depending on the model. The classic mechanical quattro, found in longitudinally-engined models like the A4, A6, and Q5, uses a self-locking centre differential to distribute torque between the front and rear axles. It can send up to 70% of torque to the rear wheels or 85% to the front, reacting to grip conditions in milliseconds. Transversely-engined models like the A3 and Q3 use an electro-hydraulic multi-plate clutch that can direct up to 100% of torque to the rear wheels when needed.
Real-World Benefits
The primary benefit of quattro is dramatically improved traction. In wet, icy, or loose-surface conditions, a quattro-equipped car can deploy its power more effectively than a two-wheel-drive alternative. This translates to safer, more confident driving — accelerating out of junctions, climbing steep hills, and maintaining stability in challenging weather conditions. The enhanced traction also means better acceleration from standstill, as the tyres are less likely to spin.
quattro in the Audi Range
At Autohaus Motors, we stock several quattro-equipped models including the Q5 40 TDI S Line and various A4 and A6 variants. If you live in an area prone to winter weather or simply want the reassurance of all-wheel drive, a quattro model is well worth considering. The additional cost over a front-wheel-drive equivalent is modest and well justified by the enhanced capability and retained resale value.
Is quattro Right for You?
If you regularly drive in adverse conditions, have a steep driveway, or simply value the reassurance of maximum traction, quattro is a wise investment. It does add slight weight and a marginal increase in fuel consumption, but for most owners, the benefits far outweigh these minor compromises.
