Although there are other auto shows in the US each year, the Detroit show is by far the most important. Thousands of photographers, reporters, analysts, editors, industrial spies, and cell-phone wielding corporate types descend annually for the press days that precede the public show. Production models making their debut include the Dodge Charger, Ford Fusion, Lincoln Zephyr, and the Hyundai Sonata. A 500hp Corvette Z06, a more potent Saleen S7, and dueling sport coupe concepts from Chrysler and Ford are sure to catch the enthusiast's eye. Concept reveals outnumbered production model introductions, and many provide a hint at products that are coming soon. The most pleasant surprises at the show include Toyota's luxurious Avalon, the ingenious Honda Ridgeline truck, Saturn's promising Aura concept, and a dual-engined, zero-turn-radius Jeep that spins.
