Like Clark Kent and Superman, the IS transforms from relaxed and refined to surprisingly capable. The base 241-hp turbo four has an eight-speed automatic with rear-wheel drive only. All-wheel drive is available on both V-6 variants—a 3.5-liter producing 255 hp or 306 hp—but they only get a six-speed automatic. An F Sport package features a sport-tuned ride, supportive seats, and aggressive styling cues. Added safety assists include automated emergency braking and adaptive cruise control.
