The 2005 Toyota 4Runner models offer more responsive performance than last year's models, whether you get the standard V6 or optional V8. The V8 benefits from a more sophisticated variable-valve setup with drive-by-wire, boosting its output to 270 horsepower, substantially more than last year's 235. Last year, the only good reason to opt for the V8 was to pull a trailer, but this year's V8 is a much more compelling upgrade, delivering strong, responsive acceleration performance out on the highway. With its 330 pound-feet of torque 4Runner 4x4 V8 is rated to tow up to 7,000 pounds.

The V6 gets enhanced response from a five-speed automatic transmission that replaces last year's four-speed automatic. (The V8 continues to come with the five-speed automatic as well.) More gears means better response for any given situation. Last year's model performed very well with the V6 and four-speed automatic, and it was our preference, but the new five-speed is a better match and offers smooth shifting and sophisticated features, including Artificial Intelligence.
