Like many other automakers in Europe, Nissan has created a special marketing badge to identify the least polluting vehicles across its range which will be used both in Europe and Japan. The chosen name is Pure Drive, which I think is one of the least imaginative on the market. Sibling company Renault's ECO2 label is more fun, as is its TV spot. As we have mentioned here, the "green label" is usually applied to a company's least powerful models that also have higher gear ratios, low-rolling resistance tires and some aerodynamic work. As for Nissan, the label is applied to those vehicles which emit less than 140 g/km of CO2. The new Pixo, the 1.2-liter gas and 1.5-liter diesel Micra and Note, the 1.5-liter diesel Qashqai, Qashquai+2 and Tiida (the Versa) now all come in Pure Drive versions.
