Tough and ready to tackle off-roading adventures, the truck-based 4Runner falls short of most modern SUVs on all other counts. Its rough-sounding 4.0-liter V6 is powerful and reasonably fuel-efficient. But the ride is unsettled, and handling is clumsy. The body leans noticeably while cornering, and the bobbing and bouncing ride chips away at driver confidence. A high step-in and low ceiling compromise access and driving position. The SR5's 4WD system is part-time only. A third-row seat is optional, and the power-retractable rear window is handy. Reliability is well above average, but it scores too low in our testing to be recommended.
