How does the Audi A4's Quattro all-wheel drive system function?

Could someone provide an explanation of the technology behind the Quattro all-wheel drive system featured in the Audi A4? I'm curious about how it manages torque distribution and if it's different from traditional AWD systems.

The Audi A4's Quattro all-wheel drive system uses a center differential to distribute torque between the front and rear axles, with a default front-to-rear torque split of 40:60. This allows for dynamic, responsive handling and improved traction in various road conditions. Personally, I've noticed a significant difference in control and stability during wet or snowy weather compared to my previous vehicles, and I highly recommend it.

As a former Audi technician, I can tell you that the Quattro all-wheel drive system is a permanent system, meaning all four wheels are being driven at all times. The torque distribution is variable, with the ability to send up to 70% of torque to the front axle or 85% to the rear axle if needed. It's a reliable and well-designed system, and I always recommend it to my clients.

I've had my Audi A4 for two years now, and I've been extremely impressed with the Quattro all-wheel drive system. It's incredibly responsive and can handle sharp turns and curves with ease. I feel confident driving on any terrain, whether it's dry, wet, or even icy. And even though it's a performance-focused system, it doesn't compromise on fuel efficiency. Overall, I highly recommend it.
