FRANKFURT MOTOR SHOW: 2012 Honda Insight

Although you might consider it's hardly a facelift - as it adds up to little more than a revision of the front fog light clusters and grille details - there's a little more about the revised Honda Insight hybrid than initially meets the eye.

Of most significance is the drop in CO2 emissions, which come under the magic 100g/km barrier and are now quoted at 96g/km, compared to 109g/km for the current model.

Honda says the improvements come from things like "enhanced aerodynamics and powertrain efficiency" plus reduced engine friction and an updated continuous variable transmission (CVT). The air-conditioning has been tweaked in the search for lower emissions, "benefiting from a new cold storage system" which also helps lower fuel consumption.

The external changes include a revised grille design to complement the new outer front bumper treatment, and a slimmer rear spoiler that "allows for a wider glass area" which, in conjunction with modified tailgate garnish and a smaller rear wiper motor, brings an overall increase in rear visibility.

As for other changes, "Adjustments have been made to the engine and suspension for an overall improvement to ride comfort and stability. The features within the interior have also been enhanced for a superior quality."

The revised Insight will make its first appearance at the Frankfurt motor show, but there are no details yet on when it will reach Australian shores.

Honda has so far sold 433 Insight hybrids since the model was launched in Australia late last year. In the same period, Toyota has sold 452 examples of its Prius hybrid.
