The peppery Swift Sport has under the new hybrid engine Suzuki The new version Hybrid ( mild hybrid ) is the first hot hatch hybrid in its history. The engine provides a new system mild-hybrid MHEV electrification that combines an electric unit ISG (Integrated Starter Generator) from 10 kW (13.6 HP) to the engine turbo petrol 1.4 BoosterJet from 129 hp. The motor/alternator group also called reversible alternator performs the function of an electric motor.

 

Advantages of hybrid mild technology, booster

The advantage of a mild hybrid technology such as that adopted by Suzuki on the Swift Sport is a real electric boost obtained from the mild hybrid configuration with a ready delivery right from low revs and an initial cue that is felt. The Swift Sport hybrid now has a torque of 235 Nm at 2,000 rpm and records fuel consumption and CO2 emissions up to 16% lower ( NEDC mixed cycle ) than the previous 1.4 BoosterJet engine.

Swift Sport Hybrid, hybrid with new Suzuki 1.4 Boosterjet engine

The 1.4 Boosterjet engine of the Swift Sport hybrid is a latest-generation four-cylinder supercharged by a low inertia turbo combined with an intercooler. The turbocharger is equipped with a wastegate control valve, which remains closed in normal driving situations to ensure quicker responses and opens instead when traveling at a constant cruising speed to reduce fuel consumption.

 

To achieve this goal, seven-hole injectors were also used, capable of perfectly dosing the quantity of fuel delivered, as well as regulating injection timing and pressure with absolute precision. The compression ratio is 10.9: 1 and the variable valve timing of the electrically controlled intake valves (VVT) optimizes combustion at all speeds.

The short-length intake ducts and the integrated exhaust manifold in the cylinder head ensure that the engine has limited dimensions and increases revs more quickly.

Suzuki Swift Sport Hybrid, how it is made and how Suzuki’s MHEV mild hybrid works

The hybrid system of the Suzuki Hybrid combined with the 1.4 Boosterjet engine consists of three main elements. The first is the Integrated Starter Generator (ISG), 48V, a 10 kW electric motor incorporated in the alternator that also acts as a starter motor. The second is a 48V lithium-ion battery housed under the front passenger seat and which recharges automatically during slowdowns, without the need for any external intervention.

The third is a converter, placed under the driver’s seat, which transforms the voltage from 48V to 12V to power the on-board services. This architecture allows us to centralize the weights as much as possible and, at the same time, contain them.

Swift Sport Hybrid, the advantages of hybrid engines

The Suzuki Swift Sport Hybrid hybrid retains a weight of only 1,020 kg, all to the advantage of reduced weight/power and weight/torque ratios. It is a weight that differs greatly from that of an electric car for which we are talking about 1,500 / 1,600 kg, a difference of 400/500 kg that is felt in driving especially on provincial roads and winding between curves.

As mentioned before, the Suzuki Hybrid system ensures Swift Sport an increase in overall torque and a systematic increase in the transitional phases. By controlling the torque integration, the electric motor responds promptly to any intervention on the accelerator pedal and eliminates the natural response delays of a normal heat engine.

With the torque boost function, then, it optimizes and strengthens the lower part of the delivery curve, making every start brighter and more linear until the maximum thrust of the turbo comes into play. Between 2,000 and 3,000 rpm, or in the most important range for road use, the torque is permanently at the maximum value, equal to a good 235 Nm. From that point on, the progression of the Boosterjet quickly pushes the tachometer needle towards the red zone.

The system designed by Hamamatsu engineers also assigns to the electric motor the task of keeping the rotation of the thermal unit at a minimum during deceleration when the clutch pedal is pressed, without the need to inject petrol and with a momentary zeroing of consumption.

Suzuki Swift Sport Hybrid, ADAS and level 2 autonomous driving

The Suzuki Swift Sport Hybrid can also count on first-rate standard equipment, including ADAS driving aid systems that ensure a level 2 of autonomous driving. The novelties are the “shoulder guard” systems, for monitoring blind spots“go ahead”, which warns of the possible arrival of other vehicles while maneuvering in reverse, and “eye to the limit”, which recognizes road signs and replicates them in the instrumentation.

The driving assistance also integrates the autonomous emergency braking system with recognition of pedestrians “attention brake”, the “straight guide” device, which avoids involuntary overruns of the center line and road exits by intervening directly on the steering to maintain the car in the center of the roadway, and the “stay awake” system, which activates a visual and an audible signal to bring the driver’s attention back to driving in the event of distraction or drowsiness. Among the ADAS on board the Swift Sport Hybrid, there is also ACC, the adaptive cruise control.

Standard accessories standard on the Swift Sport

The standard equipment of the Swift Sport also includes new rear parking sensors, sports seats with integrated and heated headrests, rearview camera, full LED headlights with twilight sensor and automatic high beam switching, keyless, rain sensor, automatic climate control, an infotainment system, with 7 “touch screen, navigator with 3D mapsDAB + radioBluetooth and MirrorLink connectivity, Apple CarPlay, and Android Auto, electrically foldable rearview mirrors, sports pedals

PRICE, how much does the Swift Sport Hybrid cost?
