While the automotive business rushes headlong into electrification, the truth is that hybrids are quick discovering favour with car consumers and outselling EVs, and that too with a really restricted selection of fashions. The leap in demand for hybrids has been pushed by Maruti Suzuki and Toyota, who, in contrast to most different automakers, aren’t dashing into the EV sport. Maruti Suzuki has as an alternative hedged its bets with a multi-fuel technique that features EVs, CNG, biofuels and, considerably, hybrids. 

Maruti Suzuki, in truth, is betting massive on hybrids, inspired by the terrific response to the Grand Vitara Hybrid, which makes use of Toyota’s famed hybrid powertrain and accounted for about 15 to twenty % of complete Grand Vitara gross sales in 2023. The Innova Hycross-based Invicto MPV – launched in 2023 – and a three-row model of the Grand Vitara (code: Y17) coming in 2025 will additional increase Maruti Suzuki’s hybrid play. 

The massive information is that Maruti Suzuki has enormous plans to exponentially enhance hybrid volumes with choices in mass segments utilizing hybrid variants of the Fronx, Baleno, Swift and a small MPV, that are all beneath growth. The masterstroke, nonetheless, is that the corporate gained’t use Toyota’s series-parallel hybrid system however is as an alternative growing an in-house and cheaper sequence hybrid powertrain that’s basically a spread extender.

Maruti Suzuki’s new sequence hybrid powertrain (code: HEV) will likely be considerably cheaper to provide than a series-parallel and parallel-only hybrid, which is the principle cause why the carmaker selected this path to counter the inherent excessive price of a powertrain that features an IC engine, electrical motor and battery. Also, the federal government has up to now refused to offer hybrids any tax profit and the excessive charge of 43 % GST in comparison with simply 5 % for EVs is the principle price barrier. To scale back the price affect, Maruti Suzuki has discovered an answer with a sequence hybrid.

What is a sequence hybrid powertrain?

So what precisely is a sequence hybrid and why is it cheaper to construct? The petrol engine in a sequence hybrid system serves solely as a generator or vary extender, thus as an alternative of immediately propelling the automobile, it produces electrical energy to energy an electrical motor that, in flip, drives the wheels. 

It is, thus, comparatively easy as a result of the electrical motor is the one energy supply driving the wheels – similar to in an EV – and the motor attracts electrical energy from both a small battery pack or from a generator run by the petrol engine. The sequence hybrid system can be referred to as a spread extender hybrid as a result of the IC engine acts as a generator to maintain recharging the EV’s battery pack. The Nissan Note is one instance of a spread extender sequence hybrid automobile, which was being examined in India.  

Advantages of a sequence hybrid

There are a number of benefits of a sequence hybrid, which makes it engaging as a mass-market choice. Firstly, the absence of a direct mechanical hyperlink between the IC engine and wheels simplifies the general design of the powertrain, thereby making it a more cost effective hybrid resolution, in addition to probably decreasing upkeep prices, and enhancing reliability – all conditions of the small-car phase.

With much less mechanical losses, the format in a sequence hybrid system provides optimised effectivity in metropolis driving, with the system excelling in stop-and-go site visitors eventualities, typical of city driving environments. 

However, sequence hybrids will not be notably environment friendly on the freeway, for the reason that electrical motor is the first supply of propulsion, the inner combustion engine (ICE) might have to work more durable to generate electrical energy. So, for long-distance driving, parallel hybrids will be extra environment friendly at larger speeds and fixed masses, since each the inner combustion engine and the electrical motor can work collectively to propel the automobile. 

So, although the parallel hybrids really feel nicer to drive, they require extra advanced transmission methods to permit each the inner combustion engine (ICE) and electrical motor to drive the wheels independently or collectively. This complexity is among the predominant the reason why parallel hybrids are costlier. 

Maruti Suzuki’s hybrid system 

The energy supply for Maruti Suzuki’s new vary of HEV-based sequence would be the all-new Z12E, three-cylinder engine. The compact Z12E will act as a generator to cost a 1.5-2kWh battery pack or drive an environment friendly electrical motor that, in flip, drives the entrance wheels. 

Maruti Suzuki’s HEV sequence hybrid powertrain will debut within the facelifted Fronx (code: YTB) adopted by the next-gen Baleno (code: YTA) in 2026. The next-gen Swift (code: YEA), which is due for launch within the first half of this yr, can be anticipated to come back with a hybrid choice, although not earlier than 2027. So till then, this highly regarded hatch will likely be a petrol-only mannequin. Other fashions in line for the HEV system are the Spacia-based compact MPV (code: YDB) and the next-gen Brezza, which can include hybrid energy solely in 2029. 

By the top of the last decade, Maruti Suzuki might have as many as over half a dozen fashions and fashions with a possible quantity of eight lakh models each year or 25 % of its complete volumes powered by hybrid tech, which incorporates Toyota’s 1.5-litre parallel-hybrid powertrain and its personal HEV 1.2-litre sequence hybrid system.

Maruti Suzuki hybrid gasoline effectivity

In a sequence hybrid, because the engine solely runs to provide electrical energy and by no means immediately takes on the driving load, it’s most frequently operating within the prime fuel-efficient rev vary. Hence, Maruti’s HEV-powered cars are anticipated to offer distinctive gasoline financial system to the tune of 35-40kpl on the take a look at cycle and also will be a key expertise to assembly future CAFE targets, that are resulting from get stricter in 2027.  

Maruti Suzuki might have botched up its diesel technique by exiting the diesel market sooner than it ought to have and likewise shedding the primary mover benefit within the EV race. But within the hybrid race, it’s quietly zooming forward while most of its rivals don’t actually have a plan. And on this decade, the hybrid race might develop into a very powerful one to win.
