The Audi SQ7 has gone through two generations and a facelift since its inception in 2005. The mid-size luxury crossover SUV sports a 4-door body style and was the very first SUV offered by Audi (which has since offered the Q5 and Q3). Today’s model of the Audi SQ7 features both diesel- and petrol-powered versions, which were released in 2015. It also released a diesel-powered plug-in hybrid, the Q7 e-Tron.
