Honda will unveil a cleaner, higher quality Insight hybrid at the Frankfurt Motor Show.

The revised 5-door hatchback will have lower CO2 emissions of 96g/km, achieved through enhanced aerodynamics and powertrain efficiency. Reduced engine friction, changes to the CVT transmission and improved air conditioning all contribute to lower fuel consumption.

These changes mean that the 2012 Insight once again qualifies for exemption from the London Congestion Charge, and falls into the lowest VED band, meaning owners will pay no annual road tax. The new figures also ensure that Insight remains in one of the lowest groups for Benefit in Kind taxation.

For 2012, the Insight also receives a refresh of the exterior design, including a new front grille. At the back, visibility is increased through the introduction of a slimmer spolier and a modified tailgate garnish, and a reduction in the size of the wiper motor.

Adjustments have also been made to the engine and suspension for an overall improvement to ride comfort and stability, and interior quality has been enhanced.
