What is the difference between Audi 40TFSI and 45TFSI?
2 Answers
Taking the 2020 Audi Q5L 40TFSI Rongxiang Fashion and the 2020 Audi Q5L 45TFSI Zunxiang Fashion as examples, the differences are as follows: 1. Maximum Power: The maximum power of the Audi Q5L 40 is 140kW, while the Audi Q5L 45 has a maximum power of 185kW. 2. Maximum Torque: The maximum torque of the Audi Q5L 40 is 320Nm, whereas the Audi Q5L 45 has a maximum torque of 370Nm. 3. Combined Fuel Consumption per 100km: The combined fuel consumption of the Audi Q5L 40 is 7.1L, while the Audi Q5L 45 has a combined fuel consumption of 7.4L.
The 40TFSI and 45TFSI are primarily different power versions of Audi's 2.0-liter turbocharged engine. I often help friends with car repairs and found that the 40 outputs 190 horsepower with 320Nm of torque, achieving a 0-100km/h acceleration in 7.3 seconds. It runs smoothly but has relatively weaker power, making it suitable for urban commuting with better fuel efficiency at around 8L/100km. The 45, on the other hand, boosts to 245 horsepower and 370Nm, cutting the acceleration time to 6.1 seconds. It delivers stronger power for highway overtaking with noticeable push-back sensation, though fuel consumption slightly increases to about 9L/100km, and throttle response is more sensitive. The suspension system of the 45 is sometimes tuned stiffer for more stable handling, with slightly more noticeable bumps, but it offers excellent grip in rainy conditions. The 45 is a few ten thousand more expensive, but maintenance costs are roughly the same. If budget is tight, go for the 40; if performance is a priority, choose the 45. A test drive will clearly reveal the differences, with power experience being the most significant distinction.
