Sustainable and Lightweight: Fasteners for Engine and Transmission

Posted by

From advancements in hybrid technologies to AI-powered cars, the automotive industry is experiencing rapid and monumental changes, including manufacturers of engine and transmission systems. 

Alternative fuels like electricity and hydrogen are currently dominating the market, and these technologies don’t require engines and transmission systems. However, electric vehicles bring with them significant range, heat and lightweighting issues, plus automotive hydrogen technology is still very much in its infancy, meaning more traditional vehicles are still in high demand. 

Nonetheless, in the face of increasingly stringent government sustainability regulations, all manufacturers are expected to improve fuel efficiency and lower the environmental impact of their vehicles, especially those producing diesel and petrol cars. The heavier the vehicle, the less fuel efficient the car is, meaning many manufacturers are turning to engineered, lightweight solutions for their vehicles. Engineering innovation for engine and transmission also remains a key consideration for those manufacturing hybrids. 


Lightweight Solutions for Engine and Transmission, down to the Smallest of Parts 

Engine and transmission manufacturers are revolutionising the design of their builds to lessen their weight, creating lucrative opportunities for engineering innovation. However, it’s important manufacturers don’t lose sight of some of the smallest but most crucial parts in their products – fasteners.  

In some projects engine and transmission fasteners can make up nearly 50% of a Bill of Materials, but may only constitute 1% of a project’s budget. Nonetheless, reducing fastener weight can have a significant impact on the overall weight – and therefore fuel efficiency – of an engine or transmission system. Automotive fasteners should therefore be made of high-quality materials and thoroughly tested before they are put to use in a vehicle application, to avoid impinging on vehicle performance.
