Audi A4 40 TFSI means the power output per liter of displacement is 40KW. TFSI refers to the TFSI engine with turbocharging, commonly abbreviated as TFSI, which is typically used in Audi series models. Below are specific details about the Audi A4L: 1. Body dimensions: The Audi A4L measures 4761mm in length, 1826mm in width, and 1439mm in height. The new Audi A4L is equipped with an 8-speed Multitronic manual-automatic transmission, providing smoother gear shifts. 2. Powertrain: The Audi A4L is available with 1.4T and 2.0T engine options, paired with a dual-clutch transmission. The engine delivers a maximum power of 185.0kW, a maximum horsepower of 252PS, and a maximum torque of 370.0N·m. 3. Exterior design: The entire lineup features redesigned front and rear bumpers, wider side air intakes, and a more dynamic overall appearance. U-shaped chrome accents on both sides of the front grille, chrome air intakes, and flat dual chrome exhaust pipes enhance the sporty feel.
I've always been fascinated by Audi's naming system. The A4 is their very popular mid-size car series, and the 40TFSI represents the engine model and performance level. TFSI stands for Turbo Fuel Stratified Injection, which simply means turbocharging combined with high-efficiency fuel injection, making the engine more fuel-efficient yet powerful. As for the number 40, it's Audi's power designation - numbers like 35, 45 basically categorize the horsepower output range, with 40TFSI typically delivering around 200 horsepower with smooth torque, making daily driving and overtaking effortless while remaining fuel-efficient. I've noticed Audi has made this naming system very systematic, applying it uniformly from the A3 to Q series. The advantage of TFSI lies in its combination of traditional turbocharging and direct injection technology, reducing emissions while improving efficiency. European tests show it consumes over 20% less fuel than older engines, with lower long-term maintenance costs too. If you value sporty performance without sacrificing fuel economy when buying a car, this combination is quite worthwhile. After test driving, I found it delivers crisp handling - stable in corners with quick acceleration, and a full tank is enough for weekend road trips.
As an owner of an Audi A4 40TFSI for several years, I feel this question is very practical to share my experience. TFSI is essentially an advanced engine design that makes the car more enjoyable to drive through turbocharging and precise fuel injection, with the 40 representing mid-range power output—quick starts in city commutes and no sluggishness on highways. My daily commute is 20 kilometers one way, averaging about 7-8 liters per 100 kilometers, which is even more fuel-efficient than some Japanese cars, especially with the smart auto start-stop system during traffic jams. The engine noise is minimal, and the cabin is quiet, making long drives comfortable for family members in the back. I remember when I first bought it, I drove over a thousand kilometers continuously under varying road conditions without needing a full tank, showing the TFSI system is well-optimized. Maintenance intervals are long, usually just an annual visit to the dealership at reasonable costs. If you're considering this car, focus on its reliability and driving comfort—friends who’ve switched to it all say they don’t regret it.
When I first started learning about cars, I didn't understand what Audi A4 40TFSI meant either. It was only after researching that I realized A4 is the model, and 40TFSI refers to the engine type. TFSI stands for Turbo Fuel Stratified Injection in English, which means turbocharged fuel stratified injection. This is a modern gasoline technology that uses compressed air to better mix gasoline sprayed into the cylinders, improving efficiency and reducing waste. As for the number 40, it usually indicates the power level in the Audi series, with 40 corresponding to approximately 190 to 240 horsepower, a medium power level. When selling new cars, dealers often emphasize that it's suitable for daily commuting and sufficient if you don't drive fast. Compared to older Audis, it has lower fuel consumption, less noise, and standard safety features like the electronic stability system, making it quite reassuring to drive in rain or snow. Overall, for beginners, the 40TFSI is a balanced and reliable option. When choosing a car, don't just focus on the numbers—try to experience the actual feel, engine sound, and acceleration.
