Car logos tend to become iconic. That's why there was a phase of the 1980s during which people were stealing them off the hoods of cars and wearing them around their necks as fashion statements. Hyundai might not have quite the same fashion appeal as Mercedes or Rolls Royce, but they still have a very distinctive logo which you can easily recognize. It's a chrome representation of the letter 'H.' It doesn't appear to be groundbreaking until you find out what it symbolizes.
You can't really tell from the modern version of the logo, but the original plan intended the 'H' to look like two people shaking hands. That's why it's at a slightly off-kilter angle. The handshake idea was supposed to symbolize the two sides of a car deal shaking hands on a sale. It could have used a little more definition to make it obvious, but now we know it's there we can just-about see it.
