British design and engineering studio Callum has selected Aqua Mist as its Colour of the Year 2025. The colour a fresh pastel blend of green and blue, it says is not only vibrant and optimistic but also promotes relaxation and tranquillity.

The company says Aqua Mist represents renewal and innovation in a fast-changing world. The refreshing, soothing hue combines the calm of blue with the rejuvenation of green, perfect for creating peaceful, balanced spaces.

It is for the first time Callum has introduced the Colour of the Year 2025, which it says will become an annual forecast of colour trends from its growing team of colour, material and finishes experts.

Charlotte Jones, colour, material and finishes designer at Callum, said, “Aqua Mist offers a fresh, calming energy. Its soft and cool undertones are associated with tranquillity and openness, providing a balanced base that doesn’t overwhelm the senses. Its versatility means it is suited to a number of applications, materials and surface textures, while layering with Callum’s specially-selected balancing colours creates a fun, energetic vibe.

Recent projects and collaborations have given us valuable insights into the needs, preferences and experiences of a variety of customers, particularly those who rely on well-considered inclusive design to enhance accessibility and comfort. We want the Callum Colour of the Year to spark conversations about how colour resonates with the emotional needs of customers and can help shape spaces and products that elicit deeper emotional responses.”

Ian Callum, Design Director, Callum, said, “Every design team in the world looks at future aesthetics to stay relevant and appeal to ever-evolving consumer tastes. Plus, it’s creative and a lot of fun. The Callum Colour of the Year 2025 is the first time we’ve made any of our forecasting work public.”

The company has identified a concise complementary palette, which sees Aqua Mist being balanced with Neon Riot and Midnight Tide, to create a playful, dynamic trio that offers an energetic yet approachable look, ideal for designs that need both vibrancy and sophistication - perfect for playful brands.

Callum stated that Neon Riot is an attention-grabbing hot pink, which brings energy, fun and vibrancy to the palette by adding a pop of brightness. Midnight Tide on the other hand is a rich, deep blue, that grounds the other two colours with its darker, more intense shade, making the overall palette feel balanced and mature.

The combination of Aqua Mist, Neon Riot and Midnight Tide in automotive projects it believes can create a bold, futuristic and attention-grabbing aesthetic, especially for brands or models aimed at trend-conscious audiences

The narrower, bigger diameter tyres of electric vehicles are encouraging innovation around them. Supporting lower rolling resistance, the tyres are pushing suppliers and OEMs to explore new technological innovations. A leading German auto supplier for example has developed a ‘mechanical’ technology to ensure superior manoeuvring with near 180 degrees turn of the steered wheels. 
This is a development that could be applied to ICE rear-wheel drive vehicles as well. Even, light-duty commercial vehicles such as the Tata Ace/1000 or the Switch Iev3/Iev4 that are aimed at the last mile delivery segment were backing up into a tight parking spot or navigating through a narrow lane is part of the job. 
As designers and engineers toy with the idea of larger wheel wells and the ability of the steered – front – wheels to turn as much as 180 degrees, the use of narrower, bigger diameter tyres with low rolling resistance in electric vehicles is spurring yet another round of innovation, albeit as a part of the entire platform architecture that is rather software driven and subject to much virtual development in the interest of ‘time-to-market’ and a differentiated user experience. 
With over 14 million small electric vehicles sold in 2023 the world over, the push has been to develop tyres that enhance operation and performance. Provide a typical ‘family’ car the ability to transform into a sports car given the wave of high torque available from the word ‘go’ in an electric vehicle. 
With electric vehicle sales poised to increase 17.5 percent year-on-year globally to bridge 41.2 million units in 2029, electric vehicle tyres are expected to facilitate a further drop in rolling resistance while employing sustainable raw materials, technologies and manufacturing processes. 
A sustainable EV tire design should consider the whole lifecycle of the product. Tires can be composed of well over 100 different raw materials. These are mixed and the rubber compounds are machined resulting is several components of the tire construction. EV tires are expected to be stronger and lighter, with less rolling resistance due to its importance in CO2 emissions and fuel consumption. 
A key challenge being the development of tyre formulations for electric vehicles with the tread compound that is more resistant to abrasion, it is the instant torque availability that is necessitating tyres that may look like ICE vehicle tyres but are quite different in the way they handle traction and aid a longer drive range. There is the issue of kerb weight as well, not to overlook the new environmental pressures for durability and abrasion resistance. 
Interestingly, new opportunities are being created on the vehicle engineering and dynamics side as well as on the side of electric vehicle tyre development and manufacture. 
Starting with materials that are broadly classified as ‘renewable’ (can be sustained on time) and as ‘recycled’ (re-used and made from recovered end-of-life tyres), it is the tandem mixers that are producing more homogeneous rubber compounds, including tread compounds that employ optimised silica fillers.
Tyres for electric vehicles are demanding the use of triple or quadruple extruders for treads and sidewalls as per the vehicle weight, application and dynamics. Roller head or roller die units are also being used to produce inner liners as a single or multilayer sheet
In terms of textile coating of steel cord components in e-vehicle tyres, four-roll and Z-type calendars are used. Also, full tyre assembly machines that can produce tyres to tighter tolerances, higher specs such as superior uniformity and sans operator invention. 
With electric vehicle tyres and ICE vehicle tyres being tested and validated differently primarily because of the higher load bearing capacity and low rolling resistance, electric vehicle tyres are made up of a different (softer) rubber compound than regular tyres with an eye on less noise, mentioned a testing expert at an OEM that is increasingly producing electric vehicles in India. 
Pointing at an electric passenger vehicle the company launched in India recently, he averred, “Softer compounds are used to ensure less rolling noise and better transmission of torque from the motors to the road.” 
With finer tolerances in need, optical machine vision systems for end-of-line quality inspections, including new technologies such as X-rays to check steel belts, cords and bead reinforcement are increasingly used. 
They are used to check for air bubbles in inner liners as well. Advances in tyre design and manufacture include new developments in simulation software to model the performance of new designs quickly. This is without material input cots. 
AI is being increasingly used to ensure superior analysis. AI is also used to automate manufacturing process as part of Industry 4.0 workflows. 

Hyundai Motor India (HMIL), one of India’s leading passenger vehicles manufacturers, has been taking huge strides to cut down on its carbon footprint both on-road and off-road.

Taking advantage of the country's robust railway network, Hyundai Motor India shipped 26 percent of its total domestic wholesale vehicles through rail freight in 2024.

This translates to a total of 1,56,724 units transported through Indian Railways, cutting down on almost 18,352 tonnes of CO2 emissions.

Interestingly, the company claims that 100 percent of its dispatches to North East India were utilised rail freight. Furthermore, between 2021 and 2024, Hyundai Motor India transported 5,37,499 vehicles using the rail route, which led to a prevention of 63,452 tonnes of CO2 emissions versus road freight.

Tarun Garg, Whole-time Director and Chief Operating Officer – Hyundai Motor India, said, “At HMIL, we have been relentless in our pursuit of promoting sustainability in all facets of our operations, be it manufacturing, dispatches, sales or after sales support. By utilising Indian Railways’ extensive rail-network for delivering Hyundai vehicles from our plant in Sriperumbudur, Chennai, to multiple locations across India. As the Government of India continues to upgrade the rail infrastructure with dedicated freight corridors and modern and energy efficient rolling stock ensuring faster movement of goods, HMIL remains committed to utilising rail freight to optimise its logistic operations, leading to long-term reduction in emissions.”
