MORE PICTURES: Turbocharged Suzuki Swift Sport previewed

Suzuki has released yet more pics of its all-new Swift Sport ahead of an official unveiling at the Frankfurt motor show.

The new pictures confirm the little hot hatch will, indeed, come with a turbocharged petrol engine that replaces the old model's spirited naturally-aspirated 100kW/160Nm 1.6-litre four-cylinder engine.

Set to offer a significant performance step-up over the current car, the turbocharged ‘Boosterjet’ 1.4-litre four-cylinder -- which also powers the Vitara SUV -- is expected to produce around 105kW.

However, that modest power bump is misleading, because the new Swift Sport should be significantly quicker than the current car.

That's because it will weigh up to 100kg less than the old Sport, with a kerb weight thought to be less than 900kg -- even though the new Swift Sport features an extra pair of rear doors.

Combine that with a more generous torque peak output of around 220Nm and the new Swift Sport will easily shave a second off its 0-100km/h time.

Once again matched with a six-speed manual gearbox (pictured), the new Suzuki hot hatch should hit the benchmark 100km/h in around 7.2 seconds -- down from the current car’s 8.7sec sprint.

To help with the performance, engineers have tweaked the standard car’s styling to incorporate a subtle new front splitter and side skirts.

At the rear of the car there are twin exhausts, a rear diffuser and a small tailgate spoiler, although that hasn't been pictured.

Featuring larger 17-inch wheels, the new Swift Sport will come with a comprehensively reworked version of the current supermini's suspension that includes a bespoke sports springs, new dampers and larger brakes.

Inside, the new images tease a pair of redesigned sport seats, a flat-bottom steering wheel and the option of a cheeky boost gauge between the instruments clusters.

Other changes include an all-new 4.2-inch touch-screen infotainment system that includes both Apple CarPlay and Android Auto connectivity.

Due on sale here around early 2018, the Swift Sport's pricetag is excepted to remain low at around $24,000, but the increase in performance could see the little Suzuki poach customers from previously faster more expensive hot hatches like the Volkswagen Polo GTI.
