SPR Auto Technologies Advances Ethanol Blend Piston Technologies

In an investor update, SPR Auto Technologies Limited announced progress on ethanol blend piston technologies developed and tested for applications up to E85. The company has evaluated its piston and piston-ring products for E20, E40 and E85 applications and is working with customers on products aligned with the latest CAFE norms. According to the company, higher ethanol blends require changes in piston and ring coatings along with different plating approaches. SPR said it has sufficient capacity to support these requirements and has already signed up with most customers for the relevant products.
Under the new CAFE norms, SPR has submitted products for customer testing and validation, with the technologies focused on reducing friction and exhaust emissions. The company is using new coating technologies alongside changes to piston-ring manufacturing strategies to address these requirements. SPR said it has already invested in the required technologies and has them available at its manufacturing facilities in Ghaziabad and Pathredi. Its engineering teams have continued developing these solutions while working directly with customers on the latest requirements, supporting product readiness for higher ethanol blends and the evolving regulatory environment.
