A recent study conducted by researchers from the International Council on Clean Transportation (ICCT), George Washington University, and the University of Colorado Boulder in the US estimated that vehicle tailpipe emissions were linked to about 385,000 premature deaths from ambient PM 2.5 and ozone worldwide in 2015. An estimated 70 percent of these occurred in the four largest vehicle markets -- China, India, the EU, and the US.

While the figures paint a grim picture, we see no urgency in bringing about an immediate improvement in air quality standards. The government of India has put a long-term policy focus on shifting to electricity as a transport fuel. However, this will bear fruits only after at least a decade of work and infrastructure development. As we wait for electric vehicles, we must not lose the opportunity to use the readily available cleaner fuels such as auto LPG which can clean the urban air faster.

In the wait for the roll-out of EVs, India is missing on the immediate environmental benefits of auto LPG, an easily deployable source of transport power. It emits up to 120 times less particulate emissions than diesel vehicles; 96 percent less nitrogen dioxides (NOx) than diesel and 68 percent less NOx than petrol. It is also more than 30 percent cheaper than petrol. Over 26 million vehicles across 70 countries run on auto LPG. South Korea sells 4 million tonnes of this fuel annually. In the US, Russia, Japan and China, governments incentivize auto gas usage with tax breaks on sales, excise, registration, parking and road use charges.

Two-wheelers

More than 40 percent of vehicular pollution in Delhi comes from two-wheelers. Across the country, 2-wheelers account for more than 75 percent of vehicles on roads. We need to start pushing two-wheelers towards cleaner fuels as well. Auto LPG makes for the most viable alternative. The 2-wheeler conversion kit is available for about INR 5000-5500 along with a convenient side fitment of the LPG Tank.

Promote Gaseous Fuels

While a large number of buses and public transport vehicles in several cities are running on CNG, it is also necessary to convert a substantial number of private vehicles to gaseous fuels. Rapidly shifting to a mix of CNG and auto LPG is an easier task than shifting to EVs. While the government supports CNG through the City Gas Distribution Project, it has left out auto LPG.

Auto LPG has several advantages over CNG, including 5-6 times less installation cost for refueling stations and less engine performance loss. Globally, auto LPG is the third most commonly used automotive fuel after petrol and diesel. Seven of the 10 large car manufacturers produce LPG-powered cars. Auto LPG occupies very little space in car boots and can be transported in cylinders in trucks to distant outposts.

Auto LPG is already available in 500 Indian cities and it neither needs any major infrastructural overhaul nor any subsidies to encourage consumers. It is important that the government frames policies that are favorable to all alternative fuels to allow consumers a wider choice.

An urgent policy intervention is to change the Type Approval norms of the Ministry of Road Transport for vehicles converting to gaseous fuels. In India companies have to renew the extremely costly Type Approvals for auto LPG and CNG conversions every three years. This has resulted in a rapid dwindling of players in the retro-fitment market. The Type Approval Validity must be made perpetual in line with the European norms. Similarly, the GST rate on LPG conversion kits for vehicles must be reduced from 28 percent to 5 percent as a measure to push up the rate of vehicle conversion to environment-friendly fuels. The GST rate on auto LPG also needs to be brought down from 18 percent.

Marquardt, a supplier of mechatronic systems, has launched a concept vehicle, ‘The Centum’, to demonstrate the integration of functional controls into automotive surfaces. The project involved a collaboration with E Ink and Covestro to develop a door interior panel that embeds a responsive display within synthetic materials.

The project aimed to maintain the tactile properties of polyurethane (PU)-coated textiles while enabling a colour-changing display to remain invisible until activated. This supports industry trends toward backlit surfaces and integrated control elements.

The display technology uses E Ink, which provides a low-energy, durable electronic paper display designed for automotive environments. For coating, Covestro has developed a transparent film using INSQIN waterborne PU technology. The coating uses Impranil DLC-F, a waterborne polyurethane dispersion used in automotive topcoats.

The resulting material retains the texture of standard automotive textiles while allowing the underlying display colors to remain visible through the coating.

Felix Hake, Head of Innovation, Marquardt, said, “With The Centum, we wanted to demonstrate how intelligent functions can be integrated into interior surfaces without compromising design or quality. Working with E Ink and Covestro allowed us to create a material solution that combines a premium tactile experience with responsive visual effects.”

Dr Torsten Pohl, Global Head of Textile Coatings, Covestro, added, “This project highlights the versatility of INSQIN PU technology and Impranil DLC-F. By developing a transparent, automotive-grade PU coated synthetic compatible with E Ink displays, we were able to support Marquardt in integrating dynamic functionality into familiar surface materials.”

Pete Valianatos, Senior Director, E Ink, said, “Our e-paper display technology is designed to deliver dynamic visual experiences with low power consumption, while maintaining the robustness required for demanding applications. Collaborating with Marquardt and Covestro has enabled us to demonstrate how E Ink displays can be integrated behind coated interior surfaces, allowing automotive designers to introduce adaptive colour features without changing the established look and feel of premium materials.

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.
