For the month of June only, buyers will be able to purchase the new 975kg pocket rocket for £16,499. From 1 July, the starting price of the third-generation model, which offers higher performance than its predecessor despite a decrease in engine size, will go up to £17,999.
The old car's naturally-aspirated 1.6-litre engine - which was the last in its class to breathe atmospheric air - has been swapped for a 1.4-litre turbocharged motor making 138bhp at 5500rpm and 170lb ft from 2500-3500rpm. Not only are these gains of 4bhp and 52lb ft, but also those respective peak outputs arrive 1400rpm and 1900rpm earlier.
The new model, equipped with the same six-speed manual gearbox as its predecessor, is therefore described by Suzuki chief engineer Masao Kobori as "more fun to drive" across a wider band of the rev range.
The extra grunt also translates into more accelerative performance, with the 0-62mph sprint taking 8.1sec, 0.7sec quicker than the old car, while top speed is 130mph, a 9mph improvement.
The new Swift Sport is Suzuki's first car to be tested under the new WLTP regime, for which it is listed as producing 135g/km of CO2 and offering a combined 47.1mpg. In the outgoing NEDC test, the car produces 125g/km of CO2 and achieves 50.4mpg combined.
