We tested the car on the undulating Millbrook Alpine Route, and 90 per cent of the time couldn’t discern it from its closest rangemate. All of the Insignia’s transferable virtues are here, including a well-appointed, classy and comfortable cabin, better-than-average passenger accommodation and some new-found good looks.
Performance feels stronger than you’d expect from an economy special, and gives credit to Vauxhall’s claim that the car is only a couple of tenths slower to 62mph than a standard 2.0-litre CDTi 160.
In normal conditions there’s enough mid-range punch for fairly swift overtaking. Only climbing the Hill Route’s steepest slopes was the car’s longer gearset evident, and only then in a little sluggishness in the upper reaches of the rev range.
Roadholding feels all-but-indiscernible from that of any other Insignia. That may be damning with faint praise in as much as the Vauxhall’s not the stand-out act in the class dynamically.
It just doesn’t quite steer precisely enough, ride subtly enough or handle deftly enough to bear comparison with a Ford Mondeo. But viewed in the right context, relative to Insignias with stiffer springs and a more overt sporting agenda, the Ecoflex is actually a bit of a triumph for Vauxhall.
While you expect compromised grip to come from the car’s low-resistance tyres, you actually get all the traction and lateral purchase you need. There’s noticeable tyre squeal in the dry as the tyres run out of adhesion sooner than performance tyres would, but the difference won’t matter during most road driving.
And considering how insignificant those compromises of performance and roadholding are, this car’s excellent economy and low CO2 seem all the sweeter.
Vauxhall claims that the car will return 54.7mpg on the combined cycle, going 10 per cent further between fill-ups than a standard 2.0-litre CDTi.
The car we tested, which was brand new and had been thrashed around Millbrook’s test routes for hundreds of miles, was returning 35mpg according to its drive computer; so we’ll wait to confirm that it really is as frugal as Vauxhall says. But even beating 50mpg on a motorway cruise would be a remarkable result for a car this size.
Should I buy one?
If impressive performance and driver thrills are what you’re after from your family hack, probably not. But then if either of those are top of your priorities list, you’re unlikely to be attracted by an Insignia anyway. Other medium-sized saloons do much better impressions of a sports car.
The fact is though that, if you do like the sound of the Insignia’s blend of virtues – practicality, style, quality, comfort and value-for-money – then the Ecoflex may be the most appealing model in the range.
It’s three brackets lower in the current ‘Benefit in Kind’ company car tax system than any other Insignia. It’s £25 a year cheaper on VED road tax. It’ll make your increasingly expensive litre of diesel go further too. And in every other way that matters it’s performance is as complete as any other version of the 2009 European Car of the Year.
