Following the first (and so far only) official photo of the all-new Suzuki Swift Sport, more details have leaked online courtesy of a brochure sourced by Twitter user @Kaz3647M3. Here, the solitary front three-quarters image of the new Swift Sport is reflected by the exterior shots of the car in the brochure, along with details of the hitherto unseen rear half of the car.

A pair of Swift Sport-distinguishing exhaust outlets feature along the new car’s rear bumper, which appears to adopt elements evolved from the outgoing Swift Sport, such as the black lower section and centrally-mounted rear fog lamp, all housed in a darker, contrasting lower section.

The leaked brochure also affords a glimpse into the new performance-biased hatchback’s interior, which can be seen to feature flashes of red highlights to denote this Sport version; these are applied to a strip across almost the whole width of the dashboard, on trim surrounds ahead of the gear lever, also featuring heavily in the tachometer and as a more subtle ring around the neighbouring speedometer.

A flat-bottomed, multifunction steering wheel greets the driver with a somewhat VW/Audi design, while the front seats appear to integrate the headrests into the seat backs. Back to the exterior, the new Swift Sport will be available in six paint colours – yellow (which continues to be the hero hue), red, blue, white, grey, and black, at least where the Japanese market is concerned.

The website quotes Japanese sources as saying the Suzuki Swift Sport will boast of a 1.4 litre turbocharged petrol engine producing 150 PS at 5,500 rpm and 245 Nm of torque from 1,500-4,000 rpm, expected to pair with either a six-speed manual or six-speed automatic.

The outgoing model’s naturally aspirated, 1.6 litre mill cranks out 136 PS at 6,900 rpm and 160 Nm of torque at 4,400 rpm. Considering the new car’s expected weight of 870 kg, around 200 kg less than the outgoing model, significant performance gains can be expected of the new car.
