Honda Civic 1.6 i-DTEC 2018 review

Welcome to the oil-burning version of the 10th-generation Honda Civic. This new 1.6-litre, four-cylinder diesel joins the petrol-powered 1.0-litre and 1.5-litre variants that were launched last year, as well as the barnstorming Type R - all of which we’re already particularly fond of.

The new diesel, which we’ve been driving on the shockingly battered streets of Rome, gains the same extensive updates that were introduced on the petrol models. Honda pulled out all the stops when it came to designing this car, dedicating a third of its research and development resources to the project. In fact, it’s the product of the single largest development programme in the company’s history.

There’s a new platform, a revised suspension set-up that comprises MacPherson struts up front and a multi-link rear axle at the back, as well as a stiffened unibody and a lowered centre of gravity. All of these changes, Honda says, have been implemented to lend the Civic a more agile and engaging driving experience.

The 1.6-litre i-DTEC engine has also been revised. New forged steel pistons replace the aluminium jobbies found in earlier incarnations of this power plant and help to reduce friction and cooling loss within the block. A new turbocharger offers reduced lag as well as improved low- to mid-range pull.

Its 221lb ft of torque is available from 2000rpm, while peak power - all 118bhp of it - is reached at 4000rpm. The key stats for this car, however, are its economy figures. Honda claims that the Civic diesel will manage 80.1mpg on the combined cycle, with CO2 emissions from 93g/km.

We’d be stretching the truth ever so slightly if we said the Civic diesel was an exciting car to drive. But then again, an oil-burning family hatchback is never going to be the sort of car to set your heart racing.

That’s not to say the Civic isn’t an impressively capable car, mind. While it’s not particularly quick - it dispatches the 0-62mph dash in a leisurely 10.5 seconds - where it scores big points is in the ride department.

You get the sense that there’s very little that will upset the Civic. Its suspension copes well over rough and uneven surfaces - even the mottled Roman roads of our test route didn’t make it flinch - absorbing jolts with little fuss, and never managing to feel anything other than planted and stable. Its adaptive dampers limit vertical travel well, and even set to their sportiest setting, the Civic feels calm and collected. Quite why a diesel Civic needs adaptive dampers is another question entirely.

It steers well, too, even if there is little in the way of feedback from the electromechanically assisted variable-ratio rack-and-pinion steering - although that’s the norm these days, isn’t it? It doesn’t roll a particularly noticeable amount through the bends, and sudden changes in direction don’t upset the Civic’s balance too significantly either. We’d like to say that it grips well, too, but the roads of our Italian test route didn’t provide much in the way of sharp bends.

It did have an abundance of faster, gentler stretches of Tarmac, though, which revealed the Civic’s excellent refinement at cruising speeds. The 1.6-litre i-DTEC is quiet, and happily sits at motorway speeds. It does lack some in-gear shove, though, but this is solved by working the six-speed manual gearbox, which is precise in its action and has a pleasingly short throw.
