IT'S a strange fact that almost no-one drives an SUV off-road.

And it's probably for this reason that the on-road driving capability of the fastest growing car sector is becoming a greater focus.

The latest best-of-breed are now virtually a match in terms of dynamics for traditional family hatchbacks, which they are elbowing out of the limelight.

Such credentials put the newest addition to the Suzuki Vitara range in pole position for attracting buyers who looking for a blend of performance, practicality and frugality.

As you'd expect, the Vitara S has the must-have embellishments that mark it out as a performance variant - black alloy wheels, red stitching in the cabin, wheel-arch guards and rear spoiler.

But what makes the real difference is the stuff under the bonnet.

The new Boosterjet 1.4 litre belts out 138bhp and boasts 41 per cent more torque than the old 1.6litre petrol engine, yet it is marginally more economical.

Its introduction supports Suzuki's prediction that petrol engines are back in fashion after recent trends favouring diesel power.

The S version becomes the flagship Vitara, with a predicted price tag of around £21,000 when the first models go out to customers in January.

Standard kit includes electric front and rear windows, air con, split folding rear seats, suede seat covering, sat nav, Bluetooth connectivity, adaptive cruise control and tilt adjustable leather steering wheel.

The only goodie that isn't available - yet - on the new version is the sliding panoramic sunroof.

Not only is the extra power noticeable straight away, but there's an immediacy about its delivery that helps turn the small SUV into a far more dynamic driver's car.

With a large increase in torque there's no longer a need to row through the six speed gearbox in search of greater urge. But should you choose to swap cogs, the change is light and crisp and the little turbocharged engine spins quietly and enthusiastically.

Acceleration is a couple of seconds quicker with a 0-62mph time of 10.2secs and max has been upped to 124mph, while the official combined economy is 52.3mpg.

An automatic option is available with near identical performance. Sadly, as yet it is a conventional unit without the benefit of a twin-clutch system as now offered in the S-Cross.

While the auto change takes some drudgery out of town driving it is no substitute for the slick six-speed manual which perfectly complements the new engine.

Suzuki's own ALLGRIP on-demand four-wheel-drive system is standard on the S, and guarantees full traction in virtually all conditions.

The suspension has been stiffened up slightly but not to the detriment of the ride, which - if anything - is slightly better than the standard car.

The body feels reassuringly rigid and there's very little wind noise despite the upright stance.

It's just as at home being hurried through tight bends as it is cruising down the motorway at the legal limit.
