Honda has confirmed official fuel economy and CO2 emissions for two new 2018 models, including the upgraded Civic 1.6-litre i-DTEC, which offers fuel economy of up to 3.5 l/100km (80.7 mpg) on the NEDC test. Comprehensive revisions to the 120 PS 1.6 i-DTEC diesel engine for the all-new Honda Civic range endow it with an outstanding combination of performance and efficiency. The improvements reduce cylinder friction, improve the efficiency of NOx conversion, and further develop the driveability of the car. Under the combined cycle of the revised NEDC test, the new Civic 1.6 i-DTEC has achieved low CO2 emissions of 93g/km, with official average fuel economy of 3.5 l/100km (80.7 mpg) recorded for all grades. The other new model tested is the 2018 Honda Jazz, which has a fresh look and the addition of a 130 PS 1.5 i-VTEC petrol engine – introduced in response to customer demand for a more powerful variant. The new petrol engine combines high output with low fuel consumption, and complies with stringent Euro 6 emissions standards. It achieves fuel economy of 5.4 l/100km (52.3 mpg) and CO2 emissions from 124g/km with the optional CVT automatic transmission. The CVT system itself has been revised to deliver a more linear and refined response under acceleration.
