The 2003 Toyota 4Runner marked the debut of the fourth generation of this rugged SUV. Four different trims were offered: SR5, Sport, Limited, and Nightshade. Powering the 4Runner was either a 4.0L V6 engine producing 245 horsepower or a 4.7L V8 engine with 235 horsepower. A five-speed automatic transmission came standard. Four-wheel drive was available making it a practical choice for off-roading. The 2003 model saw major upgrades in interior quality, ride comfort, and features. Key safety features included ABS, traction control, and electronic stability control. The fact that the 2003 4Runner brought a whole new level of refinement to the SUV, without losing any of its traditional off-road credibility, is what made it stand out in its class.
