[IkerLynn]

Audi 40 and 45 use different engines. Here is more information about Audi 40 and Audi 45: 1. Engine: The 40 model uses the low-power version of the 2.0T turbocharged engine, while the 45 model uses the high-power version of the 2.0T turbocharged engine. 2. 40 Model: The 40 model is equipped with a low-power version of the 2.0-liter turbocharged engine, producing 190 horsepower and a maximum torque of 320 Nm. This engine can deliver maximum power at 4200 to 6000 rpm and maximum torque at 1450 to 4200 rpm. The engine features hybrid injection technology and uses an aluminum cylinder head and cast iron cylinder block, paired with a 7-speed dual-clutch transmission. 3. 45 Model: The 45 model is equipped with a high-power version of the 2.0-liter turbocharged engine, producing a maximum horsepower of 224 PS and a maximum torque of 350 Nm. This engine can deliver maximum power at 5000 to 6000 rpm and maximum torque at 1600 to 4500 rpm.

I've researched Audi for a long time, and the biggest difference between 40 and 45 lies in engine power. The 40 models use a low-power 2.0T engine with around 190 horsepower, while the 45 is the high-power version, delivering a full 252 horsepower—the acceleration difference is very noticeable. The 45 version's 0-100 km/h acceleration is over a full second faster than the 40. The drivetrain is also worth noting: the 40 is mostly front-wheel drive, but the 45 often comes with Audi's quattro all-wheel-drive system, providing much better grip in rain or snow. In terms of features, the 45 usually includes larger wheel sizes and sport-tuned suspension, with some models adding matrix LED headlights and seat memory functions. Buying the 45 version essentially bundles many premium features. Although the 45 costs tens of thousands more than the 40 upfront, it holds its value better in the long run—especially recommended for those who frequently drive long distances.

I just upgraded to an Audi A4L 45 TFSI last month, having previously driven the 40 version. The difference in power is particularly noticeable. While the 40 is certainly adequate for daily driving, the 45 truly delivers driving pleasure, with strong acceleration that pushes you back into your seat and makes highway overtaking effortless. In terms of fuel consumption, the 45 uses about 1-2 liters more than the 40 in city driving, but the difference is negligible on the highway. The 45 also comes with great value in terms of features; mine came standard with sport seats and a full digital instrument cluster, which would be optional extras on the 40. Personally, I'd say the price difference of around 30,000 to 40,000 RMB is worth it for driving enthusiasts—the 45 is the more satisfying choice. After all, while you might not always need that extra power, you'll never regret having it when you do.

When I was planning to buy a car, I specifically compared the Audi 40 and 45 models. The 45 is significantly more expensive in terms of price, with a difference of nearly 50,000 RMB for the A6L. The core difference lies in the power: the 40 model has 190 horsepower, while the 45 boasts 252 horsepower, delivering more aggressive acceleration. In terms of configuration, most 45 models come with four-wheel drive and larger wheels, along with more comprehensive safety features like blind spot monitoring. The resale value is also higher, with a three-year-old 45 model fetching 20,000 to 30,000 RMB more. However, for city commuting, the 40 model has slightly lower fuel consumption and is perfectly adequate. I recommend choosing based on budget and driving needs: opt for the 45 if you frequently drive on highways, while the 40 is more economical for urban commuting.
