The differences between the A4L 40 Quattro and the 45 are as follows: 1. Power and maximum torque differ: The A4L 40 is the low-power version of the 2.0T engine, with a maximum horsepower of 190 HP and maximum torque of 320 Nm, while the A4L 45 is the high-power version of the 2.0T engine, with a maximum horsepower of 252 HP and maximum torque of 370 Nm. 2. Starting speed differs: The most noticeable difference in starting speed lies in the acceleration time. The A4L 40 takes about 7 seconds to accelerate, whereas the A4L 45 takes around 6 seconds, with a difference of approximately one second in the 0-100 km/h acceleration time.

I've driven both the A4L 40 and 45, and the power difference is most noticeable. The 40 uses a 2.0T low-power engine with around 190 horsepower, which is adequate for daily use but feels slightly sluggish at takeoff. The 45, however, is the high-performance version with 245 horsepower—stepping on the throttle delivers much stronger acceleration and more decisive overtaking. Both come with quattro all-wheel drive, but the 45's superior power reserve makes it more stable when cornering in wet conditions. In terms of fuel consumption, the 40 is slightly more economical, while the 45 can burn 1-2 more liters under aggressive driving. Both models use a 7-speed dual-clutch transmission with similar shift speeds. For mainly city commuting, the 40 is suitable, but if you frequently drive on highways or enjoy spirited driving, the 45 is more thrilling.

The differences between these two configurations are quite significant. The 45 comes standard with matrix headlights that can intelligently avoid oncoming vehicles, while the 40 only has regular LEDs. In terms of wheels, the 45 uses 19-inch rims, giving it a sportier look compared to the 40's 18-inch ones. The seat materials also differ—the 45 features sport seats with leg rests for better support and wrapping, whereas the 40 has standard seats. For the audio system, the 45 offers optional branded speakers, while the 40's base version falls short in sound quality. In terms of driving assistance, the 45 adds lane-keeping and adaptive cruise control. These configuration differences are quite noticeable in daily use, especially during long trips where the gaps in comfort and convenience become apparent.

The price difference is quite significant, with used cars of the same year also differing by 20,000 to 30,000 yuan. The entry-level 40 model can be acquired for just over 300,000 yuan, while the 45 model costs over 350,000 yuan. The price gap mainly comes from the high-power engine and upgraded configurations. However, the insurance for the 45 is more expensive, and the replacement costs for parts are also higher—for example, the price difference for a headlight assembly alone is several thousand yuan. If you're on a tight budget, the 40 offers better value for money, as it includes essentials like automatic air conditioning, a sunroof, and CarPlay. If you're after performance, the extra cost for the 45 might be worth it. It's advisable to test drive both models for comparison—the price difference could cover several years' worth of fuel.

The target audiences are quite different. The 40 suits those who prioritize practicality—it's great for school runs and grocery shopping, with low fuel consumption and minimal maintenance pressure. The 45 is more appealing to driving enthusiasts, offering exhilarating on-demand power, especially noticeable during weekend mountain drives. Although both feature quattro, the 45 pairs with a high-power engine, delivering more confidence when accelerating out of corners. Space-wise, there's no difference—both offer ample rear legroom. For frequent highway trips with a full load, the 45's extra power provides safer overtaking. If it's just for city commuting, the 40 is more than sufficient and hassle-free.
