What does Audi 40 mean?

[MacEmmett]

Audi 40TFSI indicates that this vehicle is equipped with a 2.0T low-power engine. Audi's displacement labeling is not arbitrary but is determined based on the G-force generated during the vehicle's 0-100 km/h acceleration. Introduction to G-force: G-force can reflect a car's acceleration capability. The stronger the acceleration capability, the greater the G-force, and the more power it requires. Introduction to TFSI: The 'T' in TFSI stands for turbocharged engine, while FSI is the abbreviation for Fuel Stratified Injection technology. However, due to limitations in domestic fuel quality, Audi models sold in China do not feature the fuel stratified combustion technology.

My neighbor just bought an Audi A4 with a '40' badge on it, and I initially thought it indicated the engine displacement. Actually, Audi's numbering system no longer represents displacement. The '40' is like the car's ID—the higher the number, the more powerful the car. My Audi A4 40 TFSI delivers around 200 horsepower, making highway overtaking a breeze. Nowadays, Audi uses these labels commonly, like 30 or 45, and if you see a '55,' it's basically a performance beast. This badge is crucial when buying a used car, as it directly indicates the power level—just remember to bring an experienced mechanic for inspection. With gas prices so high these days, the '40' tier is perfect for city commuting, striking a balance between fuel efficiency and meeting daily driving needs.

Last month, when I accompanied my wife to test drive the Audi Q3, I specifically asked the salesperson. It turns out that Audi's current tail badge numbers are now linked to engine power, with '40' representing an output of around 150 kilowatts. Audi adopted this naming system to make it easier for consumers to distinguish—the higher the number, the more powerful the acceleration. I tried the Q3 with the '40' badge, and it was noticeably quicker than the '35'. The salesperson mentioned that the 40 series are mostly front-wheel drive, which is more than sufficient for daily use. This numbering system is even being used on pure electric vehicles now, suggesting Audi wants to unify its brand identity. As for drawbacks, the 40 models don’t handle tire noise very well, so you’ll need to drive slower on rough roads.

Over the years of dealing with used cars, I've handled quite a few Audis. The '40' badge now basically represents mid-range power, with acceleration around 8 seconds. For example, the older A6L 40TFSI, equipped with a 2.0T engine paired with that classic DL382 dual-clutch transmission, delivers quite a punch when you step on the gas. This generation of EA888 engines does well in fuel consumption control, averaging about 10 liters per 100 kilometers in city driving. However, it's important to distinguish between genuine '40' models and those with tuned programs—last time I was buying a car, I came across one with a rolled-back odometer. I recommend checking engine parameters or putting it on a dynamometer, as the price difference can be twenty to thirty thousand.

Last year, I helped my brother pick up an Audi A6L 40TFSI and researched this numbering system. Nowadays, the 30/40/45 designations are like game account levels - the higher the number, the greater the output power. The 40 series generally falls in the 190-210 horsepower range, which is just right for daily commuting. Audi's strategy is clever - small-displacement cars carry big numbers to show class. Personally, I'd say this power level is most suitable for urban driving conditions - quick off the line with fuel consumption just over 9L. On weekend highway runs above 110km/h, it can feel a bit floaty, so I'd recommend installing chassis reinforcement components.

I've been driving an A4 allroad 40 for almost three years now, and this badge represents the car's power level. The 40 series typically comes with a low-power 2.0T engine, but with different tuning, it can achieve a 0-100 km/h acceleration in 7.9 seconds. There's still a noticeable surge of power when the turbo kicks in during daily overtaking, though the paddle shifters on the steering wheel are mostly unused. Driving at 80 km/h on the ring road in the rain, the understeer typical of front-wheel-drive cars is still present, but the electronic stability system intervenes very promptly. In terms of cost-effectiveness, the 40 saves about 20,000 yuan in fuel costs compared to the 45, and the slight difference in horsepower isn't noticeable in daily driving—the positioning is quite precise.
