The 2009 Toyota 4Runner belongs to the model's fourth generation (2003-2009). It's offered with two engine options: a 4.0-liter V6 generating 236 horsepower, and an optional 4.7-liter V8 generating 260 horsepower. Both engines are mated to a five-speed automatic transmission, with the choice of rear-wheel drive or four-wheel drive. The 4Runner is available in three trims: SR5, Sport Edition, and Limited, each offering a distinctive mix of features. The 4Runner incorporates active safety features like stability and traction control, anti-lock brakes with brake assist, and a full-court of airbags. Infotainment features include a CD player with an auxiliary MP3 jack, but there is no standard navigation or robust connectivity features like modern Toyota vehicles. Minor changes for this model year include slight revisions to the optional navigation system and some package reshuffling.
