2006 Hyundai Azera front

With a 263-horsepower 3.8-liter V6, spacious seating for five, eight air bags, and an Infinity stereo, this replacement for the XG350 marks the most powerful, most roomy, most luxurious Hyundai ever. It's also the most expensive, but you can expect it to be the least expensive in its class. Despite its modest mid-size dimensions, the Azera's Avalon-dwarfing interior space lands it squarely in Large Car territory. Hyundai's lineup is expanding almost as fast as its ambitions.
