Suzuki has completed its SX4 range of five-door hatchbacks with the introduction of two versions.

The first, the SX4 DDiS, is powered by Fiat's 120 horsepower, 1.9-litre diesel engine which is characterised by punchy performance and excellent flexibility.

The intercooled and turbocharged unit is fully exploited by a new six-speed manual transmission to give fuel consumption of 44.8 mpg (combined), while still turning in a 0 to 62 mph figure of 10.6 seconds. Emissions are similarly low, helped by a standard diesel particulate filter.

The second model, the SX4 1.6 GLX 4GRIP, introduces Suzuki's new i-AWD (intelligent-All Wheel Drive) technology in combination with the 107 horsepower 1.6-litre VVT (variable valve timing) petrol engine. This latest SX4 can stretch a gallon of fuel over 39.8 miles (combined).

i-AWD is a selectable 4x4 system, offering three alternative modes. In 4WD-Auto, the SX4 4GRIP operates as a front-wheel drive vehicle for much of the time, but as soon as there is pronounced front wheel slip, torque is also delivered to the rear for greater stability.

4WD-Lock mode allows full traction up to around 40 mph, before automatically switching over to the 4WD-Auto mode for smooth cruising. The third option, 2WD mode, enables fuel economy to be maximised.

There is an automatic option for an additional £850 on the 1.6 GLX model. Prices range from £9,999 to £12,999.
