Japanese supermini specialist Suzuki showed that it’s not afraid to think big – or at least, bigger – at the Geneva motor show when it unveiled the new SX4 crossover.

Moving up a class with the car, and choosing to go it alone by walking away from the deal that twinned the last SX4 with the Fiat Sedici, the company announced a plan to put the car into production in Hungary this autumn, and to set new C-segment benchmarks on space and fuel-efficiency when combined with four-wheel drive usability.

The new SX4 measures 4300mm in overall length – over 150mm longer than the last version. It combines a flexible cabin with up to 430 litres of boot space. It remains a relative low-rise hatchback, but ‘AllGrip’ all-wheel drive will be available, in tandem with 1.6-litre petrol or 1.6-litre turbodiesel engines. A continuously variable transmission provides a petrol-only two-pedal option. Carbon emissions, aided by automatic engine auto start stop, are as low as 110g/km.

Suzuki aimed for a high-quality European flavour to the SX4’s styling, which gets LED daytime running lights as standard. Executive Vice President Toshihiro Suzuki told Autocar that the car had been repositioned “in response to customer feedback, which indicated that a roomier cabin and a bigger boot should be priorities. We also recognize that the C-crossover segment is a big growth area in Europe,” he went on.

Suzuki was quick to point out that this larger SX4 doesn’t represent a sea-change in thinking from the firm, however. “Our reputation has been built on great small cars,” he said. “Making those kinds of cars is our key strength, and what most of our customers demand from us.”

“It’s important to move with the times, and perhaps to diversify our supermini range even further in the future,” Suzuki continued – leaving the way open for the launch of a premium supermini to rival the Fiat 500 and Citroen DS3. “But we won’t be branching out into a broader range of large cars.”

UK Prices for the new SX4 will be announced closer to its launch later this year.
