Fresher to the range is a sub-100g/km 1.6-litre oil-burner, the poster child for Honda's latest, frugal engine range. It has replaced the larger capacity all-aluminium 2.2 i-DTEC unit.
The smaller 1.6-litre turbodiesel's 118bhp of peak power and 221lb ft of torque, combined with CO2 emissions of 94g/km, make it an outstanding on-paper prospect among its peers.
As is the class norm, the engine sits transversely under the bonnet and drives the front wheels through a standard six-speed manual gearbox. As with the outgoing Civic, suspension is via MacPherson struts at the front and a torsion beam at the rear.
The smaller diesel is pleasingly unaffected by the usual rattle and clatter of diesel engines at low and middling crank speeds, and pulls as hard as many 2.0-litre units at times.
It doesn’t like revving beyond 3500rpm too much, and isn’t as refined at high revs as it is lower down. But throttle response is good, and there’s no sense at all that what you’re driving might be in any way austerity-minded.
The 1.6-litre diesel engine is very effectively isolated from the cabin, too. Honda makes a big deal of the noise and vibration reduction regime that the Civic has been through. This has resulted in extra insulation in the rear wheel arches, roof and engine bay, better door seals all round and thicker front side windows.
