The 1.0 Ecoboost is arguably the most impressive engine fitted to a Ford Focus.
Even in entry-level 100PS form, what it does with just 999cc is simply remarkable and makes its rivals’ downsizing initiatives look a little tame.
It isn’t just that its hits its eco targets so comfortably, but that, powering the Focus, it does so with such exceptional smoothness and refinement allied to energetic performance and an engagingly charismatic soundtrack.
There are two versions of this engine: with 100PS and 125PS (or 99bhp and 123bhp in old money). Both variants can twist out a beefy125lb ft from just 1400rpm and both make great economic sense.
Just how much? Well, let’s put it like this. After years of being pummelled by diesel power when it comes to running costs, the petrol engine is making a comeback. This 1.0-litre EcoBoost unit proves it.
Let us give you a few comparisons within the Focus range to make the point. The 100PS version of this 1.0-unit compares directly to a diesel Focus with a 95PS 1.6 TDCi engine and returns exactly the same 109g/km CO2 figure, so will be just as cheap to tax. True, this petrol unit’s 58.9mpg combined cycle fuel figure isn’t quite as good as the diesel’s, but it gets within 9mpg of it, a difference balanced out anyway by the realisation that petrol is up to 10p per litre cheaper to buy and the fact that this petrol Focus is around £1,000 less to buy than its diesel stablemate in the first place.
