Aiming to rival the likes of Volkswagen's 100bhp Golf TDi and Ford's new Focus TdCi, the four-cylinder Civic promises refinement and performance in equal measures. Developed with the help of turbodiesel expert Isuzu, it certainly isn't short on muscle, offering 100bhp and 220Nm from only 1,800rpm and capable of taking the Civic from 0-60mph in 11.2 seconds.
But although the newcomer proves impressive against the clock, it's the performance at lower speeds that is most surprising. At idle the motor is as quiet as any in its class. Although there is a very slight knock when the unit is revved, there's no corresponding boom from the exhaust. Honda's engineers attribute the refinement to thicker underbonnet foam insulation as well as noise-absorbing felt behind the dash.
Select first ratio in the five-speed manual gearbox and the car moves smoothly away. The engine pulls cleanly from as low as 1,300rpm yet also manages to rev happily past 4,000rpm, too. Thanks to its variable-nozzle turbocharger, the common-rail motor does not show any sign of slowing as it heads towards its 5,000rpm red line, either. However, the early version we drove did show a slight drop in refinement as it was revved hard, although this was a small price to pay for the engine's versatility.
Despite the impressive performance, Honda is still hoping that the Civic diesel will offer class-leading economy. Early unofficial tests have seen it returning more than 60mpg in mixed driving conditions. Carbon dioxide emissions are expected to equal a company car tax-busting 129g/km.
The handling remains as sharp as that of the familiar petrol version, too, even allowing for the extra weight of the diesel engine and additional soundproofing. And inside, the Civic's well established reputation for space and build quality remains unblemished. Yes, Honda's first home-developed diesel is a serious prospect, and it bodes well for the company's future in this competitive sector of the market.
Honda's new 1.7-litre CDTi engine is certain to guarantee the Civic a much firmer foothold in Europe's fiercely fought diesel market. It is refined, powerful and economical - essential if it is to challenge for class honours. It is also well priced and has a varied range.
