The GS competes well, delivering a balanced combination of ride, handling, quietness, and roominess. Engaging to drive, the car's good handling and taut, yet supple ride compete well against German rivals. Its strong 3.5-liter V6 returned 21 mpg overall in our tests. Rear-drive versions get an eight-speed automatic, while AWD versions get a six-speed automatic. A hybrid with a CVT is also available. Interior space is on par for the class, and the cabin is nicely furnished. A distracting mouselike controller works the infotainment systems. A high-performance GS F with a 467-hp V8 is available. 2016 brings a rear-drive 200t with a turbo four-cylinder. A blind-spot monitor with rear cross-traffic alert is standard. Reliability has been well above average.
