After a series of leaks, the all-new Suzuki Swift has finally been launched in Japan, with six trim levels offered there – RSt, Hybrid RS, RS, Hybrid ML, XL and XG. The fourth-generation model will make its official world debut next year at the Geneva Motor Show.

As detailed previously, two engines will be available – the K10C 1.0 litre Boosterjet turbocharged three-cylinder and K12C 1.2 litre twin-injector Dualjet NA four-cylinder. The former produces 102 PS at 5,500 rpm and 150 Nm of torque at 1,700 to 4,500 rpm, while the latter makes 91 PS at 6,000 rpm and 118 Nm of torque at 4,400 rpm.

The K10C is only offered on the RSt, and is paired with a six-speed automatic transmission, driving the front wheels. Meanwhile, RS, XL and XG models that are powered by the larger of the two mills, get either a five-speed manual or CVT instead, with a choice of two- or four-wheel drive.

The two hybrid models – Hybrid RS and Hybrid ML – employ the K12C motor, but introduces a 3.1PS/50 Nm DC synchronous electric motor that acts as the car’s integrated starter generator (ISG). The ISG is linked to a dedicated lithium-ion battery pack and helps to assist the engine during acceleration, idling stops, as well as generate electricity while decelerating.

All hybrid models can only be had with a CVT, although there are two- and four-wheel drive options. According to Suzuki, the hybrid Swifts will be able to do 27.4 km/l (2WD) or 25.4 km/l (4WD) following the JC08 cycle, while non-hybrid models are capable of achieving up to 24 km/l (2WD, CVT).

Suzuki also adds that the Swift now rides on its new Heartect platform, which promises improved rigidity, performance and a weight savings. For the latter, the Swift now weighs between 840 kg and 970 kg, about 30 kg or up to 160 kg less than before. The car continues to use McPherson struts at the front and a torsion beam at the back, and gets disc brakes as well.

Dimension-wise, the hatchback now measures 3,840 mm long (+10 mm), 1,695 mm wide (unchanged), 1,500 tall (-10 mm) and with a wheelbase of 2,450 mm (+20 mm). However, the four-wheel drive hybrid models are taller at 1,525 mm (+15 mm) compared to the rest of the Swift range.

Resting on the Heartect platform is a body that appears to retain its predecessor’s profile, but with several updates. At the front, you’ll note the new LED headlamps, along with the slightly more curvaceous bonnet and pronounced wheel fenders. Suzuki offers two 16-inch wheel designs, along with a single 15-inch set, depending on variant choice.

The C-pillar design also gets reworked to feature a “floating roof” look, with a small area of it being blacked out, to accommodate the “hidden” rear door handles. Moving to the rear, the Swift’s taillights are more square-shaped than before, and there is a clearer separation between the rear hatch and number plate section. Models with the ‘RS’ designation are fitted with model-specific bumpers, front grille, side skirts and roof spoiler.

Moving inside, the Swift’s cabin has been revamped, now sporting a more upmarket appearance than before. Main changes include the new dash, circular air-con vents, two-tone trim, climate control switchgear, flat-bottom steering wheel and instrument cluster.

In terms of equipment, the Swift (depending on variant) can come with automatic air-conditioning, touchscreen infotainment unit (with navigation, Android Auto and Apple CarPlay compatibility and an assortment of inputs), reverse camera, keyless operation, paddle shifters and steering wheel controls

However, it is the hybrid models that get the fancier items, like a multi-info colour display (other variants get a monochrome display) with eco-related functions, and a light bar that shows the current state and efficiency of the hybrid system.

The biggest improvement is seen in the safety and driver assistance feature set, with up to six airbags (dual front, side and curtain), ESP and ABS being standard items. On higher-spec models, there is even a camera and laser radar fitted just behind the rearview mirror, allowing for brake assist, autonomous emergency braking (AEB), lane departure warning and adaptive cruise control functions.

The new Swift is priced from 1,343,520 yen (RM51,268) , and goes all the way up to 1,941,840 yen (RM74,107) in Japan. What do you think about the all-new B-segment model?
