The Q5 is nearly as fun and as rewarding to drive as a sports sedan. The ride is steady and composed on the highway, but can feel too firm at first. Its turbo four-cylinder engine and eight-speed automatic racked up a commendable 21 mpg overall in our tests. Though the four-cylinder delivers plenty of performance, it is louder and less refined than the 3.0-liter, supercharged V6, which is a real treat. The cabin is elegantly modern and quiet, with very supportive seats, but rear-seat and cargo space are modest. The infotainment system has a steep learning curve, but ultimately proves logical. A sportier 354-hp SQ5 and a hybrid are available.
