I've driven Audis for ten years, and the difference between the A8 and A6 is quite significant. The A8 is the flagship sedan, nearly 5.3 meters long, with enough rear legroom to cross your legs, and comes standard with air suspension that makes speed bumps feel like stepping on cotton. The features are top-notch—the four-seater version includes foot massagers, a fridge that can chill champagne, and a night vision system that's incredibly useful on dark mountain roads. The A6 is much more practical, with a standard wheelbase length of 4.9 meters that fits perfectly in regular parking spaces. The entry-level front-wheel-drive version has a fuel consumption of just 8L/100km, and maintenance costs are 40% cheaper than the A8. Last time I helped a friend choose a car, with a budget of a million, we went for the A8 to enjoy the executive seating. In the 600,000 range, the A6 3.0T quattro is the best value, accelerating in just over 5 seconds and equipped with laser headlights.

Last month at the dealership, I test drove both models. The A8 drives like a mobile palace. The leather-wrapped dashboard with real wood trim and the rising B&O audio system create a full sense of ceremony when starting up. What surprised me most was the rear-wheel steering—this over-five-meter-long car turns more agilely than an A6. The A6's interior is more modest; although it also has three screens, there's more plastic. Driving the A6 on the highway, I noticed the difference in sound insulation. The A8 uses double-glazed glass—whispers are clear at 120 km/h, while the A6 has noticeably more tire noise. In my opinion, choosing a car depends on needs. For personal driving, go for the A6 Sport edition with dynamic steering. For business receptions, the A8's rear executive seats are a must.

After comparing the specifications, the A8 uses the MLB Evo platform with an aluminum body that is 90kg lighter. The powertrain starts from a minimum of 3.0T, and the 55TFSI comes with a 48V mild hybrid system. The air suspension can adjust by 60mm, making it easy to climb curbs in off-road mode. The A6 primarily features a 2.0T engine, and the 45TFSI version is sufficient but lacks variable steering ratio. In terms of active safety, the A8 offers full L2 assistance, with city road adaptive cruise control capable of recognizing cutting-in vehicles. However, the A6's intelligent parking system is more user-friendly, allowing remote control via smartphone for tight parking spaces.
