Isuzu has made a few changes this year to make the Rodeo more appealing to SUV shoppers. First off, there's a new range-topping 3.5-liter V6 that makes 250 horsepower. Last year's 3.2-liter V6 has a new home in the base model; the four-cylinder engine has been dropped. Other alterations this year include a new Sound Package, a new Color Package and a new tire-pressure monitoring system.
