Hyundai Genesis Sedan Preview – 2008 Detroit Auto Show: Yeah, we know it's not January yet, too, but apparently someone forgot to tell Hyundai executives in Korea. According to multiple sources, they spilled the ol' beans about the Genesis sedan a little early to Korean journalists. Ummm...go ahead and cancel those fireworks for Detroit, Bob. With a V-8 making 375 horsepower, something tells us that this Hyundai will make its own fireworks just fine.
