Accommodating up to seven passengers, the Q7 is the largest crossover available in the Audi lineup. Under the hood is a selection of three engines including a turbocharged 2.0-litre four-cylinder, a turbocharged 3.0-litre V6 and a twin-turbo 4.0-litre V8. The first one is now backed by a 48V mild hybrid system that helps save fuel and increases output to 261 horsepower. Meanwhile, the sporty SQ7 can be specified with new 22-inch alloy wheels.
