As best I could figure out, the article says the IQ has a few big advantages over the Smart. Room, Quality of interior Etc.
It also says the IQ's ride is much better, and the transmission is more suitable for a small car. I couldn't quite catch the reference to a scooter trans, unless they were talking about the feel of an old centrifugal clutch.
The IQ sounds like a welcome addition to the list of micro cars that will soon be on the roads here in the US.
This all Sounds fun, but I'd rather have A Nano as a second car to our Smart. Now that would be a kick! Ta-Ta for now.
