The new 2020 model car document discusses two new Audi SUV models, the Q7 and SQ8. Both SUVs are powered by a twin-turbocharged 4.0-liter V8 engine producing 500 horsepower. The Q7 has reverted back to being petrol powered after a short time as diesel, and the more luxurious SQ8 is making its debut as the first petrol version.
