NISSAN Australia must be nervous indeed, replacing the conventional Pulsar with the distinctly offbeat Tiida. Changing the well-known name against its will (Japan insisted) hasn’t helped either. And in almost every department the Tiida won’t conform to the small-car norm that presently is the most popular out of all the vehicle segments. But are these bad things? Is Nissan actually clever for realising that different might end up being better? Or is the newcomer just a jumped-up light car? The answer may surprise you.
