A6's multitronic continuously variable/manual integrated transmission, for the first time in the history of luxury sedans, achieves true continuously variable transmission. It adopts a metal chain drive method, completely replacing the traditional gear set transmission method, so the power output is completely free of jerks, smoother than ordinary automatic transmissions, and has the quick responsiveness of manual transmissions while also being more fuel-efficient and offering more comfortable control. The newly added S gear enhances acceleration capability and increases driving pleasure. The following are the factors affecting acceleration: Engine maximum power: The engine's maximum power is the decisive factor in determining the car's top speed. As the saying goes, 'Acceleration depends on torque, top speed depends on power.' If the engine power is very small and the car is very heavy, it will be like a small horse pulling a big cart, and the car's top speed will definitely not be high. Only when the engine outputs its maximum power and the car is traveling at a constant speed, that speed is the highest speed. Air resistance encountered during high-speed driving: Among the various driving resistances of a car, air resistance has the greatest impact on the car. According to tests, when the car speed exceeds 120 km/h, air resistance accounts for about 80% of the total driving resistance; when the speed exceeds 180 km/h, the resistance encountered by the car is almost entirely air resistance, and other resistances can be negligible in comparison.

I've been driving the A6L 45TFSI for almost a year now. When starting from traffic lights in the city, it basically outperforms most cars. The 2.0T high-power engine is truly impressive. Step on the accelerator, and the push-back feeling comes immediately, with the gearbox shifting so fast it feels like you're being pushed forward. A few days ago, I tried the sport mode on the highway, and the acceleration beyond 120 km/h is still on demand, without any hesitation. However, with a body length of nearly five meters, you can feel the tail being a bit heavy during quick lane changes. This car is more suited for steady straight-line acceleration. It's much better than my dad's old A6. The new mild hybrid system makes low-speed response even quicker, making overtaking in the city basically a matter of just choosing who to pass.

As a user who has deeply experienced mid-to-large-sized sedans from BBA, the A6's acceleration is definitely in the top tier among its peers. The other day, I drove a friend's 55TFSI version—the 3.0T V6 paired with quattro all-wheel drive launches from standstill as if catapulted, with barely any lift at the front. For daily driving, the 45TFSI is more than sufficient, with the turbo delivering its strongest punch around 2,000 rpm, making highway overtakes effortless without needing much lead distance. It's streets ahead of the laid-back acceleration of a Lexus ES, and while it may trail the BMW 530 in handling, it holds its own in straight-line speed. I’d recommend trying the optional dynamic steering system for sharper acceleration through corners.

Last week I test drove the A6 45TFSI. When it comes to acceleration speed, it really depends on what you're comparing it to. It's definitely not as aggressive as hot hatches, but among mid-to-large size sedans, it's at an excellent level. The official 0-100km/h time is 7.8 seconds, but in reality it's even faster, especially in the 30-80km/h mid-range acceleration which feels particularly responsive. The electric turbo has virtually no lag, and the transmission downshifts extremely aggressively - you don't even need to use the paddle shifters for quick overtaking. However, the real beast is the 3.0T 55 version, where even light throttle inputs make it jump forward. If there's any downside, it's that the start in Eco mode feels slightly sluggish, but switch to Dynamic mode and it's like driving a completely different car - the quattro system ensures all power gets to the ground without any wheelspin.

Researching the acceleration of the A6 depends on the specific model. The 40TFSI with the low-power 2.0T version is merely adequate, but switching to the high-power 45TFSI transforms it entirely. I've observed the engine's RPM characteristics—the torque plateau starts at 1600 RPM and is exceptionally broad, delivering a slight push sensation even in D-mode normal driving. The most impressive aspect is the transmission logic; a hard press on the throttle can drop three gears seamlessly without any jerking. If the budget allows, I strongly recommend the 55TFSI hybrid version. With the electric motor compensating for low-end torque, the initial acceleration becomes even sharper, ensuring you're always the first off the line at traffic lights. It's far more generous than the Mercedes-Benz E-Class's 1.5T at the same price point, and the relentless mid-to-high-range acceleration typical of German cars is truly addictive.

My A6 45TFSI commutes 70 kilometers daily, and what I love most is its linear acceleration feel. During morning rush hour traffic, a light tap on the throttle makes it inch forward, and as soon as the revs pass 2000 rpm, that thrust kicks in, perfectly complemented by the steering wheel paddle shifters. Once, rushing to catch a flight, I hit 180 on the airport expressway, feeling like the power reserves were bottomless. The secret lies in its drivetrain—Quattro distributes power intelligently, ensuring no wheel slip even on wet surfaces. It's far superior to Japanese cars that just roar without moving and unlike some American cars that are all brute force. Over time, I've found Sport mode to be the highlight, with crisp, forceful gear shifts paired with simulated engine sounds that make driving exhilarating.
