What is the engine displacement of the Audi Q5 40TFSI?
3 Answers
40TFSI is a model designation used by Audi in the Chinese market, which has undergone adjustments in displacement labeling. Instead of the traditional naming method based on displacement (e.g., 1.8T, 2.0T, 2.4), it now uses a number derived from the G-value calculation of acceleration from 0 to 100 km/h. The number 40 represents the vehicle's acceleration magnitude. TFSI indicates a 2.0-liter displacement. Below are some details about TFSI: 1. TFSI is Audi's patented technology, meaning Turbocharged Fuel Stratified Injection engine. Since stratified combustion technology must rely on direct fuel injection, it can be simply referred to as a 'stratified combustion turbocharged engine.' The 'FSI' stands for Fuel Stratified Injection, which refers to the combination of direct fuel injection and stratified combustion technologies. 2. The TFSI in Audi models adds a 'T' to FSI, representing turbocharging technology. However, due to the quality of fuel in China not meeting the requirements for stratified combustion, the FSI models in China have eliminated the stratified combustion technology, retaining only the direct fuel injection.
From a technical specifications perspective, the Audi Q5 40TFSI is equipped with a 2.0-liter turbocharged engine. Although the number 40 might make people think of a 4.0-liter displacement, Audi's current rear badge numbers actually represent power levels rather than actual displacement. This EA888 engine utilizes variable valve lift and dual injection technology, making it nimble for city starts and providing sufficient power for highway driving. According to the technical manual I checked, the specific displacement is 1984cc, and it runs well on 95-octane gasoline. Regular maintenance should include timely oil changes, especially since it's a direct-injection engine. For family use, this power output is more than adequate, and the fuel consumption is pleasantly surprising.
I've been researching various mid-size SUVs lately, with particular focus on the Audi Q5. The 40TFSI version is indeed equipped with a 2.0T engine, and the combination of 197 horsepower with the 7-speed dual-clutch transmission is tuned very smoothly. Many friends have asked about the displacement labeling - simply put, Audi changed its naming convention to use numbers indicating acceleration performance levels. In actual driving, there's slight turbo lag at low speeds, but once the revs hit 2000 rpm, you can feel the strong acceleration. If you frequently drive on mountain roads, I'd recommend choosing the 45TFSI, but for daily commuting the 40 has more than enough power.
