What do Audi 35, 40, 45, and 55 mean?
2 Answers
Audi 35, 40, 45, and 55 indicate the horsepower of the engine. Here is an introduction to Audi's engine knowledge: 1. Meaning of the numbers: 35 generally refers to 1.4T, 40 generally refers to the low-power 2.0T, 45 generally refers to the high-power 2.0T, and 55 generally refers to 3.0T. These numbers represent the G-value, reflecting the car's acceleration. The larger the value, the higher the horsepower and the better the performance. 2. Supercharged engine: In 2008, Audi first introduced a supercharged engine—3.0TFSI, which was equipped on the 2009 A6L (C6PA). Since then, the 'T' in TFSI is no longer purely turbocharged.
Great question! Those numbers on Audi's rear badges like 35, 40, and 45 aren't engine displacements but power level codes. I've studied their calculation method—it uses the formula 'number = 100 × log(horsepower/kW) + 25.37' rounded to the nearest integer. Simply put, higher numbers mean more power: 35 (~150 hp) suits daily commuting, 40 (~190 hp) enables zippy overtaking, 45 (~245 hp) delivers proper acceleration push, while 55 (~340 hp) feels racetrack-ready. Even within the same model line, different numbers indicate significant engine tuning variations, with suspension systems also calibrated by power tier. When choosing, don't just compare prices—decide whether you prioritize relaxed commuting or spirited driving.
