Factors such as ‘time-to-market’, regulations and costs are tilting the tables in the direction of modular vehicle architecture. This includes the design and assembly of all sub-systems of a vehicle in a modular manner. This also includes design standardisation and that of the production of auto parts in the form of modules.  

The advantage of modular vehicle architecture can be clearly seen at the final 'assembly' stage were numerous variants (read as trims) can be positioned seamlessly and without bringing an entire operation to the halt for the want of a module, part of an assembly tool. 

While the first instance of the employment of modular vehicle architecture in India may be hard to pin point, it was Ashok Leyland that announced the launch of a modular architecture in the form of the medium and heavy-duty AVTR truck platform as the BS VI emission norms came into effect in 2020.  

The move reminded of the comprehensive modular architecture approach of Swedish truck maker Scania. The kind of modularity Scania built into its trucks was such that its customers could choose from a wide range of aggregates such as engines, transmissions, chassis, cabin and more to build a truck that would best address their application requirements.  

Unlike the Scania’s approach to modularity, Ashok Leyland chose to offer its truck buyers the choice of engines, transmissions, suspensions, cabins and superstructure so that they could build a vehicle that met their business needs.  

One of the key reasons why Ashok Leyland chose to go down the modular architecture route was the need to cut down on components such as the exhaust parts. There would have been parts that the company would have to produce in many numbers and types to address the customer requirements in the BS VI era had it not taken to the modular approach.  

Not only did the AVTR modular architecture helped streamline the supply chain and control the costs better, it made sure the buyer of an Ashok Leyland medium or heavy-duty truck could choose from more than 600,000 unique combinations.  

Like Ashok Leyland, Tata Motors has also been quite active in design and development of modular architectures. It developed the modular truck architecture in the form of the Prima many years ago along with its Korean Daewoo commercial vehicle arm. Not limiting itself to the Prima, the company developed modular architectures in the form of the Signa and Ultra. 

It was the modular approach that led to the creation of some brilliant models such at the Signa 3118 and the Ultra 3118.  

On the passenger vehicle side, the ‘ALFA’ modular architecture is being put to good use by Tata Motors in reducing the time to market and in controlling the costs as it competes with some of the most agile global passenger vehicle manufacturers in its home market as well as other markets in the world. 
The ‘ALFA’ modular vehicle architecture is currently supporting the Altroz and Punch. It is also the basis for the electric Punch that is expected to be launched soon in India.  

Allowing a differentiated design approach and subsequently multiple body styles to meet the evolving aspirations of customers in the automotive market, the ‘ALFA modular architecture – termed as ‘Agile Light Flexible Advanced’ and basis for an exciting e 45X concept – is playing a crucial role in meeting the high-volume demand for an entire portfolio of cars at Tata Motors as of now.  

The beauty of the ‘ALFA’ architecture is such that it could be used to create diverse vehicles with distinct body styles with a variety of powertrains (petrol, diesel, CNG and even electric), transmissions, drivelines, suspensions etc, mentioned a source. A combination of body styles, hardware and software could be deployed to offer the necessary attributes, he added.  

Pointing at the recent introduction of Punch CNG with twin-cylinder CNG technology, he informed that the ‘ALFA’ modular architecture is helping to expand the scope of twin-cylinder CNC tech as much.  

The differentiating factor of the technology is that it does not eat into the vehicle storage space. The vehicle body can receive necessary reinforcements to bear the additional weight of the cylinders. In the CNG Punch, the suspension too has been suitably strengthened to handle the additional weight.  

Observing that the CNG Punch is just one part, the source said that the electric Punch would mean that the ‘ALFA’ modular vehicle architecture has truly come to age. Claimed to be undergoing advanced testing and validation, the electric Punch would further enhance Tata Motors’ lead in the electric passenger vehicle space. It is expected to be introduced by the end of this year or early next year.  

The ambitions that Tata Motors has regarding its EV portfolio could be derived from the fact that on 29 August 2023 it announced a new brand identity TATA.ev for its EV business. It is aligned with Tata Motors' commitment towards sustainability and innovation.

EVs influence modular vehicle architectures
EVs are turning to be a big factor for the creation of modular platforms lately as they promise less complexities pertaining to platform engineering, keeping them to the bare minimum. Modular electric vehicle architectures are also enabling the development of core platforms with standardised design and production of auto parts in the form of modules and a streamlined as well as compact final 'assembly' as per the positioning of models. 

The R&D and production costs, shortening the development cycle of new models, facilitating the unification of quality standards and improving the overall strength of products, modular electric vehicle architectures are enabling unique ‘oil-to-electricity’ transformations as well.  

Dedicated modular electric vehicle architectures are enabling clever integration (read as badge engineering) across brands and as a part of the new cooperation strategies. With software defined vehicles the order of the day, electric vehicles especially, the tilt towards modular vehicle architecture is proving to be beneficial in terms of offering a differentiated user experience, to keep control over the supply chain and to keep control over the costs and to test and validate.

German automotive luxury brand Audi has launched the new RS 5, featuring a high-performance plug-in hybrid system and a rear transaxle equipped with electromechanical torque vectoring. Marketed as quattro with Dynamic Torque Control, this system manages transverse torque distribution between the rear wheels within 15 milliseconds.

The system enables torque shifts between the rear wheels regardless of the power applied. Unlike mechanical equivalents, it operates during throttle application, off-throttle states and under braking.

It features a High-Voltage Actuator that uses a water-cooled permanent-magnet 400-volt electric motor providing 8 kW and 40 Nm of output. Overdrive Gears components use actuator torque to transfer differences of up to 2,000 Nm to the driveshafts.

The differential consists of a conventional unit with a low lock percentage that distributes applied torque to the left and right shafts.

The technology is designed to reduce understeer and oversteer by directing torque to the wheel with the most grip. If the vehicle begins to oversteer in a bend, the system increases torque at the inside wheel to provide stability. Conversely, it reduces torque at the inner wheel to prevent understeer, redirecting power to the outer wheel for traction.

Control is centralised via the HCP1 (High-Performance Computing Platform), which harmonises driver inputs with environmental data. This platform interprets steering intentions to provide unfiltered transfer to the wheels.

• Electromechanical torque vectoring at the rear axle works in conjunction with front-axle supports:
• Electronic Differential Lock: Enhances front-axle traction via the brakes.
• Brake Torque Vectoring: Provides additional front-end assistance.
• Adaptive Shock Absorbers: The twin-valve units are calibrated with the rear transaxle to improve throttle response and corner entry.

The system allows for customisable driving characteristics through various drive select modes, ranging from a balanced setup to a rear-biased configuration. Audi states the ‘fixed coupling’ of this electromechanical solution ensures torque distribution remains independent of drive torque, a distinction from clutch-based torque splitters.
