What does Audi's 45TFSI mean?
2 Answers
Audi's 45TFSI refers to: the number 45 represents the vehicle's acceleration, with a higher number indicating stronger power; TFSI stands for a turbocharged engine that supports fuel stratified combustion technology. A turbocharged engine refers to an engine equipped with a turbocharger, and its maintenance methods include: 1. Avoid pressing the accelerator pedal sharply after starting the engine; 2. Do not turn off the engine immediately after prolonged high-speed operation. Taking the Audi Q7 as an example, it is equipped with a 2.0T inline 4-cylinder turbocharged engine, with a maximum power of 185 kW and a maximum torque of 370 Nm. It is paired with an 8-speed automatic transmission, and its drivetrain is front-engine four-wheel drive. Both the front and rear suspensions use multi-link independent suspensions.
Oh, I've always been curious about this 45TFSI badge. From my personal research, it's Audi's naming convention for vehicle power levels, where the number 45 likely indicates an engine output in the range of 200 to 250 horsepower. TFSI stands for Turbo Fuel Stratified Injection, which combines turbocharging with efficient direct fuel injection technology. This enables quicker acceleration, cleaner fuel combustion, better fuel efficiency, and smoother operation. Compared to traditional engines, TFSI delivers a more fluid driving experience in Audi models like the A4 or Q5, where it's commonly used to differentiate trims—such as the lower-powered 40TFSI or the higher-end 55TFSI. It makes city commuting effortless, keeps the car stable during high-speed cornering, reduces fuel worries, and only requires spark plug checks during maintenance. Overall, Audi's naming simplifies the car selection process, appealing to those who appreciate the fusion of technology and performance. However, buyers should still consider their budget, as insurance premiums might be slightly higher.
