Honda is extending the engine range of the new Civic with a revised version of its existing 1.6-litre i-DTEC engine - the first diesel in the line-up of the new hatchback - on display at the Frankfurt motor show and available to buy from March.
Despite upgrades including higher-strength pistons and low-friction cylinder bores, the car’s power and torque remain the same at 118bhp and 221b ft. The differences add up to a fuel economy under the new WLTP testing procedure of 76.3mpg, with CO2 output of 99g/km.
Honda now makes the pistons of the engine from a chromium-molybdenum steel alloy, while the bores have been subject to ‘super plateau honing’, which smooths the movement of the pistons.
In addition, Honda claims that the engine will be more refined and quieter than before, thanks to greater rigidity in the engine through the use of more cast ribs on the cylinder block.
To improve NOx emissions, the new engine has an improved storage converter, which stores the harmful gas until the regeneration cycle is under way, while a soot sensor improves the longevity of exhaust parts such as the particulate filter.
On top of the new engine, the new Civic will be available with Honda’s nine-speed automatic gearbox later in the year. It’s the first time Honda has put the transmission in a two-wheel-drive car, following its introduction to the new CR-V in 2015.
