Honda is to launch the new version of the Civic at the Frankfurt Motor Show in September. The car will be available in showrooms from early 2012. As we saw with Renault recently, improvements in energy efficiency and emissions are a top priority with car manufacturers at present.
Honda has managed to reduce the emissions of its 150PS 2.2-litre i-DTEC diesel engine to 110g/km of CO2. Interestingly, Honda has managed to do this without reducing the capacity of the engine – unlike Renault, which has been steadily downsizing its diesel engines and offers a choice of 1.6 or 1.9-litre diesels with lower power levels and similar emissions in its Civic-class car, the Megane.
Honda has taken a similar route to several other manufacturers in improving the efficiency and emissions of the new Civic. In the engine department, a number of changes have been made that combine to gether to achieve worthwhile gains.
The oil flow through the engine has been carefully managed to reduce circulation loss, while the build materials have been revised to reduce friction in the moving parts. All models fitted with a manual gearbox also benefit from Idle Stop technology which achieves a 5g/km reduction in CO2 emissions.
Commenting on the changes, Katsushi Watanabe, Development Leader for the Civic’s engine said:
“To achieve a good CO2 figure, you need to optimise every aspect of the car. Reducing the emissions was our key target and we’re proud to say that we have achieved this without compromising the high performance character of the engine. We want our customers to have fun when they drive this car.”
The old Civic body always looked pretty slippery, but the aerodynamics of the new car have been tweaked to reduce drag still further while also improving stability at high speeds. The photos alongside this article show the car being tested in disguise – standard practice for car manufacturers before the official launch date of a new car. The photos suggest that it will look fairly similar to the current model – evolution, not revolution.
