Suzuki Swift Highlights
During interior design, lowering the seating positions ensured sufficient head clearance and added 23mm vertical and lateral space for the rear seating positions. The fronts seats were moved outwards by 10mm which increased the centre-on-centre distance between them by 20mm.
New-generation 'HEARTECT' lightweight platform
Under the ‘SUZUKI NEXT 100’ plan announced at the Frankfurt Motor Show in 2015, Suzuki developed a new platform strategy for its future models and the Swift is the third model (following Baleno and Ignis) to adopt this platform and be introduced in Europe.
The Swift rests on the latest generation platform known as “HEARTECT” that delivers enhanced fundamental vehicle performance due to being light and highly rigid. A comprehensive overhaul of the underbody’s structure and component layout resulted in the adoption of a highly rigid frame that enhances collision safety and has a continuous, smooth and curving form to help disperse energy quicker.
This has led to a reduction in reinforcements, making the body a lot lighter and more spacious than the previous Swift, and greatly contributing to lower fuel consumption. Also, optimising the underbody together with the components that are attached to it as a unified whole rather than focusing on partial optimisation of individual components.
This platform or underbody of the latest Swift is 30kg lighter than before which has contributed to the car registering a kerb weight of just 890kg (SZ3 model), over 100kg lighter overall.
The bodyshell (Body in White) is also of lightweight construction and includes the use of Ultra High tensile steel (980Mpa) across 17 per cent of its structure and High tensile steel (789 MPa) across four per cent of its structure.
Aspects of Styling Innovation
Development of the latest Swift’s exterior design was based on the concept of a “bold evolution of Swift’s DNA”. While resolute efforts were made so that Swift would inherit the model’s characteristic styling, elements that needed refreshing were boldly transformed to innovatively evolve the new car.
Enhanced carry-over elements include strong shoulders, blacked-out A-pillars and vertically arranged front and rear lamps. Swift now offers a more emotional appearance together with a muscular and well-grounded look. The body is shorter, lower and wider, while a wide and aggressive front grille, supporting bumper grille character lines all express strength.
The look of a low centre of gravity is further established by blacked-out pillars that create the appearance of a floating roof. Pillar-mounted door handles add both style and a sporty flair, while a high-tech look comes in the form of LED signature illumination used in the headlamps and rear-combination lamps (SZ5 model).
For the interior, the highly dimensional instrument panel highlights a sense of nimble speed, while sporty and sophisticated white accents and satin chrome throughout the cockpit work with a basic tone of black to create a high contrast interior space. The instrument cluster features either a colour or monochrome LCD in the centre, with a coolant temperature and fuel gauge incorporated within the two main gauges.
Other interior features include a centre console turned five degrees towards the driver, front seats with optimised shape and spring position with heightened side bolsters, new design steering wheel with ‘D’-shape section and an LED auto air conditioning panel (SZ5 models):
Adopting Suzuki’s latest generation platform strategy minimised the size of the engine compartment which has enabled maximising the space available for cabin occupants and luggage. Within its compact body size, Swift features a roomy and comfortable cabin with ample space between occupants, ample headroom and legroom contributing to its relaxing environment. The luggage capacity with rear seats raised is 265L which is 25 per cent larger than the previous model.
The Swift suspension utilises traditional MacPherson strut design at the front and beam axle at the rear and various upgrades were made during development. For example, the front stabiliser bar is shorter than the previous model and of hollow design and the subframe is of lighter construction. At the rear, redesigned components include a new shape crossmember and modified trailing arms to further enhance cornering stability.
The steering rack is of variable ratio design which allows the angle of the wheels to change depending on steering input. The variable ratio increases response when the driver begins to turn the wheel to help achieve more direct and sharper handling.
For greater manouverability this system has a wide turning angle with a reduced turning radius of just 4.8 metres. The steering rack itself is of hollow design to help reduce weight.
Suzuki first introduced its 1.2-litre (K12C) Dualjet technlogy in 2014, initially in the Swift, followed by Baleno in June 2016 and Ignis in February 2017. This technology is utilised for the latest Swift and includes the addition of SHVS (Smart Hybrid Vehicle by Suzuki)
In summary, Dualjet incorporates Suzuki’s latest engine technology and uses twin fuel injectors for improved fuel economy. Utilising Dualjet design that positions the fuel injectors very close to the engine inlet valves allows for a finer fuel atomisation (or mixture) which in turn provides a more effective transfer into the cylinder. Internal modifications to the engine include the use of a new design inlet port and combustion chamber. Other mechanical parts are also modified to reduce frictional losses and facilitate smoother running.
The piston crowns have a slight bowl shape to achieve higher air turbulence inside the cylinder and the pistons incorporate cooling oil jets to help reduce internal temperatures. Additionally, an Exhaust Gas Recirculation (EGR) system is used which helps avoid abnormal combustion or ‘knocking’. The maximum power output is 90PS with a torque figure of 120Nm at 4,400rpm. Acceleration time to 62mph is 11.9 seconds for the SZ3 2WD and 12.6 seconds for the SHVS ALLGRIP equipped model.
The Hybrid system (known as Smart Hybrid Vehicle by Suzuki or SHVS) is a compact and lightweight system that incorporates an Integrated Starter Generator (known as ISG) which acts as both a generator and starter motor, the ISG is belt driven and assists the engine during vehicle take off and acceleration and also generates electricity through regenerative braking.
The system also uses a compact high performance 12V lithium-ion battery placed under the front passenger seat to store energy and incorporates an idle stop function operated via the Integrated Start Generator. The SHVS system only uses its conventional engine starter motor when first started from cold, under all other conditions it uses the ISG unit to allow smooth and quiet engine restarts. The ISG unit has a power output of 2.3kW and a torque figure of 50Nm.
The energy assistance provided during acceleration enables the SHVS to be known as a hybrid system which is ideally suited to a compact car and adds just 6.2 kg to the overall weight.
In situations that require higher fuel use, such as when starting from a standstill or accelerating, SHVS helps suppress fuel consumption by providing electric motor assist using electricity generated through regenerative braking. Because the ISG uses a belt drive rather than a conventional starter motor to restart the engine after an automatic engine stop it allows for a quiet and smooth start.
Furthermore, the light and long-life lithium-ion battery has excellent regenerative efficiency, which increases the frequency of engine assists. The battery also supplies power to electrical components for the engine, instruments and also the audio system.
Advanced Safety equipment
The Swift adopts Suzuki‘s Total Effective Control Technology (TECT) concept that provides a high level of collision safety. Some of the features include collapsible structures that absorb impact energy in the event of a collision, a frame structure that effectively disperses impact energy, and rigid cabin structure.
Other safety features include ESP® (Electronic Stability Program), which helps ensure stability while driving, along with front, side and curtain airbags to protect occupants in the event of a collision from the front or side.
High beam assist
At speeds of 25mph or higher, high beam assist is designed to automatically switch the headlights between “High” and “Low”, depending on the presence of other vehicles and also the lighting environment.
Adaptive cruise control
When there is a vehicle in front, the adaptive cruise control system uses millimetre-wave radar to gauge the distance to it and automatically maintains vehicle-to-vehicle distance in line with the setting selected out of three possible settings. When there is no vehicle in front, the system maintains the speed (from 25mph to 100mph where permitted) as input by the driver.
Lane departure warning function
When the vehicle is travelling at vehicle speeds of approximately 37mph or above and is departing the lane without the driver using a turn signal, the system vibrates the steering wheel and lights a warning indicator in the instrument cluster to draw attention to lane departures caused by factors such as inattention to the road.
Weaving alert function
When the vehicle is traveling at vehicle speeds of approximately 37mph or above and is weaving from side to side within a lane, the system sounds a warning buzzer and lights an indicator on the instrument panel. This quickly draws the driver’s attention to weaving caused by drowsiness or other factors.
Display audio system with navigation and smartphone connectivity
The audio system for SZ-T models has a Smartphone Linkage Display Audio (SLDA) with a large seven inch touch panel display that enables intuitive operation. A three dimensional navigation map makes landmarks easy to distinguish and the system also allows the driver to use certain smartphone applications with MirrorLink, Android Auto and Apple CarPlay connection.
Apple CarPlay is the smarter and safer way to use iPhone in the Swift. Apart from making calls it also facilitates receiving directions for optimised traffic conditions, listening to music, accessing email, text messages and more.Text here ...
