For 2007, buyers have a choice of two engines: RAV4's time-tested 2.4-liter four-cylinder or a powerful 3.5-liter V6 backed by the smooth shifts of a fuel thrifty 5-speed automatic overdrive transmission. There are three distinct trim levels: Base, Sport and Limited. The Base and Limited are available with 5 or 7-passenger seating; the Sport is a 5-passenger model. The Base model includes an impressive list of standard features. The Sport delivers the look and feel of performance. And the Limited is loaded with upscale features.
