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.

G Sathiyaseelan, Chairman, SIAM Styling and Design Group and Vice-President, Ashok Leyland, shared his views on empathetic, inspirational and innovative approach towards technology and design,

Anuj Prasad, CEO and Founder, Desmania, expressed confidence in the bright future for automotive designers.

The event saw speakers acknowledging that automotive styling has become an old word, while design and sustainability are the modern buzzwords that indicate the direction in which the automotive sector must head.

“The level of design happening in India holds tremendous potential. We are at the threshold of a new era in design and innovation. Today, international organisations are looking to India for designs that cater to both local and global markets. Automotive design will help build the nation in a responsible manner,” said Prasad.

Prashant Banerjee, Executive Director, SIAM stated that “Indian automotive designs today are as good as Italian designs.”

Samarth Gupta, Senior Technical Specialist & Mobility Lead APAC, Autodesk, said, “Everyone wants to own a vehicle because it is an expression of independence. The urban population landscape is changing due to climate change. New developments in geopolitics and the evolution of consumers’ trends and preferences are impacting the mobility landscape. We will need to evolve our auto design thinking amidst disruptions.”

Teofilo Plaza Garcia, Industrial Studio Head, Hero MotoCorp, said “Motorsports-based designs can be used for road-based vehicles, as indicated through Hero XPulse 210. These vehicles will no longer be as expensive as before.”

Rahul Pandita, Regional Head, Stratasys, stated that 3D block printing is a useful technique that has helped companies like McLaren bring racing designs to life quickly. “As design processes such as 3D block printing decrease the time taken, companies can quickly decipher whether a design is feasible or not,” said Pandita.

Dinesh Raman, Director, Transportation Design, KISKA Shanghai, opined that “As the years go by, greater use of AI will be made for design, thereby freeing up time for creative pursuits by automotive designers.”

VS Deka, Group Manager, Royal Enfield, said, “AI innovation is coming into our lives and we need to adopt the evolving technology. AI can be customised through training and then be scaled up as per requirements.”

Ferdinand Klauser, Global Partner & MD, Asia, KISKA Shanghai said, “India has a lot of potential in bringing about the transformation in mobility designing landscape.”

He also mentioned that though the future is unpredictable, it is possible to plan for it by understanding that consumer needs are transforming faster than the market.

Professor Kaustuv Sengupta of NIFT Chennai, stated, “Colour represents around 20 percent of the design language. Every 300 miles in our country, you see a new colour context. Human beings see a small spectrum of colours. Colours affect us psychologically. We see what we want to see.”

Rajesh Gogu, Vice-President (Design), Maruti Suzuki India, revealed that the company decided to create a completely new design for the fourth generation of the Dzire. The design became a success despite a 55 percent market share for SUVs.

“The trends on the road are changing, as demand for sedans have reduced while that of SUVs have grown. Designing can reinvent declining segments or products to make them popular again. Innovation is not just about technology, it is also about shape, form, aerodynamics, performance and more. We can design our vehicles that can reduce the carbon footprint offering better fuel efficiency and value to customers,” averred Gogu.

While describing the role of AI in automotive designing, Harikrishnan AK, Delivery Manager, TCS Design, said, “AI image generators can be used for inspiration, exploration and for happy accidents but there are challenges of confidentiality and originality. We need to harness the full potential of AI by customisation and fine-tuning.”

Speaking about designing in the commercial vehicle segment, Pravin Gaikwad, Head of CV Design, Tata Motors, said, “We have adopted multi-powertrain strategy. It is possible for the form to get you the trust of the customer. Form is actually helping us to define many ideas. We are leveraging tech intelligence like telematics to design something very unique.”

He shared an insight on how Tata Motors was using space intelligence as a new design direction for making Tata Prima trucks and a new space-saving concept called Tata YU.

The SIAM Styling and Design Conclave also presented automotive design students of MIT (Maharashtra Institute of Technology), ADYPU (Ajeenkya DY Patil University) and NID (National Institute of Design) an opportunity to present their design prototypes. Vedant Barve, a student at MIT, won the first prize for an electric cruiser scooter concept.

“When we began, India had only two design schools. Today, there are over 1,500 design schools producing a strong talent pool for automotive design. We need to be transformative and move toward defining automotive design that is human-centric and sustainable,” added Prasad of Desmania.

“To make India into a global design hub, change that helps India use aspects of its culture while competing at a global level is needed in the academic curriculum,” concluded Sumer Singh, Associate Professor, IIT Delhi.

German tier 1 supplier Continental has announced its latest solution for the automotive industry, the Ac2ated Sound display, a first-of-its-kind in the industry that uses a display surface to bring high-quality audio output.

The technology will not only enable space saving but also could enable significant weight reduction and allow for more innovative solutions to be integrated.

The Ac2ated system uses actuators installed behind the display surface and induce audible vibrations in the glass. The company stated that humans have an intuitive ability to identify the origin of a detected sound in a three-dimensional space, which is referred to ‘sound localisation’. In simple terms, humans, when hearing any sound, have a natural tendency to try and identify the source of the sound. In the automotive industry, the Ac2ated Sound display can create a more immersive experience as the display itself could be used like a sound box.

Given the smaller footprint of the actuators, the solution can be implemented in various flat components of the vehicle interiors.

Continental claims that Ac2ated Sound system requires up to 90 percent less space and can offer up to 40 kilograms of weight saving compared to conventional speaker systems.

Pavel Prouza, Head of User Experience (UX) Business Area, Continental, said, “By integrating actuators into the display, we have succeeded in using the entire display surface as a sound chamber to resonate sound within the vehicle – all in exceptional quality. Not only does this save valuable space in the vehicle interior, but it also reduces weight compared with traditional speakers. The system leverages our full expertise as a system integrator for the benefit of our customers – combining visual and audio output in a single package without compromising on quality.”
