Modular Automotive Architectures Are Flavours Of The Day

Modular Automotive Architectures Are Flavours Of The Day

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.

Audi Unveils The Nuvolari: A 1,001 PS Formula 1-Inspired Hybrid Supercar

Audi Nuvolari

German luxury automotive company Audi has officially introduced the Audi Nuvolari, its first-ever supercar featuring a high-performance hybrid powertrain. The company believes it is destined to become the fastest and most powerful production vehicle in the history of the brand. Production of the vehicle will be strictly limited to 499 units with customer deliveries scheduled to commence in the first half of 2027.

Named after the legendary, fearless pre-war racing driver Tazio Nuvolari, the pre-production prototype represents a monumental shift for the manufacturer. It serves as the pioneering production model to debut Audi’s brand-new, visceral design philosophy.

The technical core of the Audi Nuvolari features a complex hybrid system sporting four distinct drive units that push out a combined maximum system output of 736 kW (1,001 PS).

It uses a mid-mounted 4.0-litre V8 biturbo engine that generates 588 kW (800 hp) and 730 Nm of torque. Heavily derived from motorsports, it revs up to an impressive 10,000 rpm. The engine is further complemented by three axial flux electric motors, which include two oil-cooled axial flux motors on the front axle, outputting up to 2,150 Nm of torque and enabling fully variable torque vectoring. A third electric motor is sandwiched between the mid-mounted engine and the transmission. The system relies on a lithium-ion battery with a gross capacity of 7.3 kWh.

The Audi Nuvolari has a claimed acceleration of zero to 100 kmph in under 2.6 seconds, upto 200 kmph in 6.8 seconds and a top speed exceeding 350 kmph.

To safely manage extreme velocities, Audi worked closely with its Formula 1 drivers to refine the car's aerodynamics. The vehicle features an S-duct – a vented front end that channels air to increase front-axle downforce while reducing lift – and a deployable adaptive rear wing. The wing automatically morphs through three operational configurations: Closed (minimising drag), Low Downforce (LD) and High Downforce (HD).

In its peak HD setting, the aero package generates more than 400 kg of downforce. Drivers can also manually deploy a steering-wheel-mounted Drag Reduction System (DRS) on straights to lower the wing and bleed off drag.

Structurally, the supercar utilises the renowned Audi Space Frame (ASF) technology but pairs it with an all-carbon fibre exterior for the first time in brand history. Virtually all body panels are built using high-tech prepreg autoclave technology to ensure maximum rigidity with minimal mass. Forged centre-lock wheels also make their production debut on this vehicle.

Quattro Predictive Ride

The vehicle premieres quattro predictive ride, an advanced evolution of Audi's signature all-wheel-drive system. Using a highly responsive vehicle state model fed by real-time telemetry (including yaw rate, steering angles and grip levels), the car proactively calculates traction thresholds.

Before a tyres-slip event can occur in a corner, the car seamlessly modulates longitudinal and lateral torque vectoring, tweaks active aero downforce and applies targeted brake interventions to stabilise the chassis.

Through physical rotary dials on the steering wheel, drivers can select from four core modes, plus a dedicated track setting:

  • E-Hybrid: For fully electric, emissions-free urban driving.
  • Balanced: Prioritises everyday driving comfort, efficiency and baseline performance.
  • Dynamic: Optimises throttle response and sharpens cornering precision.
  • Dynamic+: Focuses the entire hybrid powertrain on delivering maximum emotional performance.
  • Track Mode: Tailors traction control behaviour to specific track environments, allowing drivers to manually step settings across Wet, Dry, Race, or completely Traction Control Off (TC Off).

The Nuvolari employs a motorsport-derived brake-by-wire system with an energy absorption capability of up to 2.8 megawatts. It permits purely electric regeneration up to 0.3 g before seamlessly engaging its hydraulic anchors.

The physical hardware consists of the new Audi Ceramic Pro braking system, utilising Formula 1 long-fibre carbon brake discs and a custom internal cooling design that boosts thermal dissipation by 21 percent over conventional carbon-ceramic brakes. Massive 10-piston fixed calipers clamp down on 420x40 mm discs at the front axle, while 4-piston calipers handle 410x32 mm discs at the rear.

The cockpit layout strips away secondary digital clutter, keeping all vital human-machine interface (HMI) menus directly inside the driver's primary line of sight. The visual identity features anodised aluminium accents and premium lightweight carbon-fibre bucket seats.

The interior is cleverly split into two distinct colour zones: a dark, muted front cabin designed to optimise high-speed driving concentration and a lighter Shadow Dune layout in the rear.

In a historic nod to Audi's rich racing heritage, the colour accents utilised across the digital HMI screens are styled as a direct tribute to the legendary 1930s Auto Union Type C speed-record race cars.

Gernot Dollner, Chairman of the Board of Management, Audi AG, said, “With the Audi Nuvolari, we are accelerating technological progress. It shows what is possible when the focus is on technology, performance, and execution through teamwork – and when we achieve progress together.”

Rouven Mohr, CTO, Audi, added, “With the Audi Nuvolari, our entire team has once again demonstrated its technical expertise, innovative strength, and dedication. This is reflected not only in the vehicle’s performance and its Formula 1-inspired technologies, but also in the ability to transfer innovations quickly and precisely into a production vehicle.”
