Transient phenomenon – Suzuki hybrid models – Car-Engine

Suzuki has made radical weight reductions on its Heartect-based cars – 10-15% of the weight of any overweight car has been cut off without compromising occupant protection. Then, at the last minute, the EU twisted on fleet consumption standards, leading the brand to take a radical step: hybridizing its entire car offering (and Jimny escaped into a commercial vehicle).

What is a hybrid drive?
We can talk about a hybrid, ie double-drive, if, in addition to the internal combustion engine, it can also be driven by an electric motor – not to be confused with dual-operation, which means internal combustion engines running on several fuels (petrol or diesel). There are basically two types, the soft hybrid, in which the electric motor alone cannot move the car, only the internal combustion engine is unloaded, and the full hybrid. Within this category, we distinguish between self-charging and mains-operated drives according to the method of charging the battery, the latter can cover tens of km without local emissions due to their large battery capacity.


Based on sales feedback and a poll, Suzuki was confronted with the fact that a significant proportion of customers have no idea what a hybrid drive means, so they organized a test drive where we could try out different solutions one after the other. Hybrid propulsion is a transition between vehicles powered by internal combustion engines and electric cars, despite the billions of euros spent on battery development in recent years, batteries are still expensive and low in energy density, and the efficiency of internal combustion engines needs to be improved until a competitive alternative arrives.

Soft hybrid
The easiest way to do this is with a soft hybrid system, with a simpler 12-volt version for the Ignis and Swift, and a more expensive 48-volt version for the Vitara and SX4 S-Cross. The electric motor is actually a more powerful generator that is strapped to the internal combustion engine to relieve and assist and start the hot resource. As long as the power output of the internal combustion engine is speed dependent, the electric motor is instantaneous, so the latter can help the petrol engine through the weak points; with this, say a reconnection can be saved. A 3 hp / 50 Nm starter generator is paired with the intake petrol engine, and the more powerful 48-volt soft hybrid system is used for recreational cars manufactured in Esztergom due to their size and weight and engine power. It also has a voltage converter in the system and a lithium-ion battery with a larger capacity. The power of the electric motor connected to the belt of the internal combustion engine is already 13.6 horsepower at a torque of 53 Nm, the latter being enough to help accelerate this amount of floor gas with so much extra. The saving potential is around 0.5-1.5 liters / 100 km, depending on use.

Self-charging hybrid
Toyota, which introduced the solution to the automotive industry, initially called the term Full Hybrid, but the term self-charging hybrid is used to suggest that the system produces energy from a lithium-ion battery onboard – either by the internal combustion engine or by braking energy during deceleration. -with recovery. Toyota needs to be mentioned here because Suzuki has a strategic partnership agreement with it, and not only the hybrid drive, but the car marketed under the name Swace itself comes from a competitor.

With this car, the electric motor can move the car on its own, the small capacity of the battery limits the electric range to a few km, but even in urban conditions this results in up to 60% electric operation! With an internal combustion engine of 98 hp / 142 Nm and an electric motor of 74 hp / 163 Nm for the Swace, the electronics deliver up to 136 horsepower to the front wheels. Experience with Toyota has shown an average fuel consumption of less than 5.0 l / 100 km, which is not so bad with a 4.6-meter station wagon.

Mains chargeable hybrid
Finally, the Across RV, which has an electric range of up to 75 km due to its larger battery capacity. 18.1 kWh is too large a capacity to be filled by a gasoline engine or brake energy recovery, this can be done from the grid – the term socket is inappropriate in so far as many experiments with induction charging without a physical connection are being experimented with. The 306-horsepower system comes together with a hybrid system at the front (185 hp / 225 Nm petrol engine, 182 horsepower) and a separate electric motor at the rear (54 horsepower), making the Across a sporty place worthy of the brand’s top model. .

Suzuki takes a closer look at the benefits of electric cars without range and fast recharging, as surveys show that the 75 km electric range is roughly double the average daily user. Of course, there is no need to compromise even if the program is a family visit to a destination where there is no electric charging station nearby.
