The four-wheel drive system of the Audi Q7 is Audi's unique quattro system. The term 'quattro' has long become the hallmark of Audi's four-wheel drive technology, capable of adapting to various road conditions, including excellent handling performance even on complex surfaces like snow and ice. The crown gear differential in the quattro system makes the four-wheel drive structure more compact, lighter in weight, and allows for a wider range of torque distribution. The Audi Q7 is a mid-to-large SUV that emphasizes comfort, with an overall length of 5086 mm and a wheelbase of 3002 mm, making it one of the larger models in the SUV segment. It also offers versatile seating and cargo space combinations to create different spatial configurations.
The Audi Q7's four-wheel drive system is the quattro permanent all-wheel drive. From a technical perspective, its core is the mechanical crown gear differential, which defaults to distributing 60% of power to the rear wheels and 40% to the front wheels. However, if a wheel slips, the differential instantly adjusts the distribution ratio automatically, unlike electronic systems that have delays. This system reacts quickly, and you can clearly feel the stability when driving in rain or snow, with no body sway. I've researched that Audi has optimized the chassis integration on the Q7, allowing the off-road mode to lock the differential for easy hill climbing while also improving fuel efficiency. Daily maintenance is simple, and it rarely has issues, given that quattro's decades of history prove its reliability. As a car enthusiast, I appreciate this combination of traditional mechanics and modern control, making driving more reassuring.
