A GLANCE at Mazda's SUV line-up and you might be reminded of ‘Russian doll' design.

Each of the four high-riders is a replica in profile of the others. At the bottom of the range is the CX-30, followed by the CX-5, CX-60 and the seven-seater CX-80.

Apart from the styling, the one common factor is that each model possesses dynamics that are generally superior than those of its rivals. Excellence of driving performance is a bottom-line for Mazda, and it's a quality that has stood the Japanese maker in good stead over the years.

The CX-30 first appeared seven years ago, but received an injection of freshness last year when the trusty 2.0litre engine was replaced - no, not by a miniscule three-cylinder or by a full hybrid - but by a larger 2.5-litre with active cylinder shutdown tech, which allows it to run super frugally when driving gently.

Efficiency is further enhanced by mild hybrid technology.

Mazda, always a firm to plough its own furrow, knows its stuff and the formula works admirably. Our average of 42.5mpg over some challenging routes proves the point that large engines can be frugal.

Based on the 3 Hatchback, it shares much of the running gear but, thanks to greater height, adds more head and leg space. The hatchback boot can accommodate 430litres of luggage which measures up well to rival small SUVs. Fold down the seats and there's space for 1,406litres.

Space in the front is ample, with decent shoulder room and enough seat adjustment to allow six-footers to travel comfortably. It's a different story in the back where legroom is a bit restricted if those in the front wish to extend their seats. It's also somewhat claustrophobic because of the narrowing side windows.

Now for the driving - always a Mazda strength. The engine revs freely and smoothly and thrives on being pushed. Acceleration is brisk and feels nippier than the 9.5 second time to 62mph suggests. Mid-range clout is also punchy.

The 138bhp engine - which is both quieter and silkier than its installation in the new larger CX-5 - is matched to one of the best manual gearboxes available. The six-speeder slices through ratios with infinite ease and is a pleasure to use.

The ride is somewhat firmer than most rivals but this is justified by the CX-30's athleticism which allows it to corner with greater assurance and confidence, feeling well planted at all times. There's little body roll and the steering is precise, nicely weighted and reasonably informative.

The Takumi version, driven here, comes with plenty of treats including heated seats, head-up display and heated steering wheel as well as leather upholstery. By SUV standards, the driving position is set relatively low but vision from the driving seat is good.

The cabin is quite sombre with lots of black, soft touch, high grade plastic mouldings which blend with flashes of dark brown - an unlikely mix but one that is quite effective and adds a touch of class.
