The Santa Fe is built on a Sonata-derived platform, at the same Hyundai plant in Montgomery, Ala., that manufacturers the company’s volume-selling sedan. That makes the 2007 Hyundai Santa Fe about as different a vehicle from its predecessor as the 2006 Sonata was to its progenitor – which is to say, significantly improved in terms of space, power and refinement. Given that the Santa Fe has been a sales leader for Hyundai since it debuted, Hyundai engineers also introduced several significant refinements to the nuts and bolts of this new SUV, such as a revised suspension and a new engine.
