What engine is used in the Audi Q8?
3 Answers
Audi Q8 is equipped with a 3.0T turbocharged engine, whose function is to convert the thermal energy of gasoline into mechanical energy by burning and expanding gas in a sealed cylinder to push the piston to do work. Taking the 2019 Audi Q8 as an example, it belongs to the mid-size SUV category, with body dimensions of: length 5006mm, width 1995mm, height 1704mm, wheelbase of 2995mm, fuel tank capacity of 85L, and curb weight of 2290kg. The 2019 Audi Q8 features a multi-link independent front suspension and a multi-link independent rear suspension, with a maximum horsepower of 340PS, maximum power of 250kW, maximum torque of 500Nm, and is paired with an 8-speed automatic transmission.
The powertrain configuration of the Audi Q8 is quite interesting. I once test drove the 55 TFSI version, which uses that 3.0-liter V6 turbocharged engine. This setup can squeeze out a maximum of 340 horsepower, with torque hitting a solid 500 Nm. Paired with an 8-speed automatic transmission, it delivers exhilarating acceleration and overtaking performance. Technologically, it employs a 48V mild hybrid system—the engine automatically shuts off at red lights to save fuel, and the start-stop operation is notably smooth. On the road, the chassis handles bumps with impressive solidity, and during high-speed cruising, the RPM stays low, around just over 2000 rpm at 120 km/h. However, climbing hills with the AC on in summer does make the fuel consumption a bit unpredictable. The SQ8 version is even more aggressive, packing a 4.0-liter V8 biturbo with over 500 horsepower—the acceleration push feels like riding a roller coaster.
If you're recently looking at used Q8 models, there are significant differences in engines across model years. The entry-level versions before 2022 still used the EA839 series 3.0T V6, tuned to deliver 340 horsepower maximum, equipped with a mild hybrid system consisting of a BSG motor. However, the new models have discontinued the 50 TFSI version, leaving only the 55 TFSI and SQ8 as options. The SQ8 uses a 4.0T V8 engine codenamed EA825, featuring twin turbochargers, capable of accelerating from 0-100 km/h in just over 4 seconds. When purchasing, remember to check the maintenance records - the V8 version requires spark plug replacement every 20,000 km, while the V6 version requires 0W-20 grade engine oil. Both engines were co-developed with Porsche Cayenne on the same platform.
