A significant shift in power sources for the iconic Caterham Seven has been announced, with a new name joining its extensive lineup. The renowned sports car, known for drawing energy from diverse origins such as Vauxhall, Ford, Rover, Suzuki, and even an experimental supercharged V8, is now set to embrace the innovative Horse alliance. This partnership unites Renault, Geely, and Aramco, focusing on advanced combustion and hybrid technologies.

An upcoming addition to Caterham’s engine portfolio is the compact 1.3-litre turbocharged four-cylinder unit, code-named HR13. Delivering an output of 130 horsepower and matching torque figures, this engine represents a departure from the more traditional setups seen in previous models. Although details remain scarce regarding its lineage, it incorporates cutting-edge features like a uniquely shaped cylinder head designed for weight reduction and integrated exhaust manifolds to enhance performance responsiveness.

Initially earmarked for Caterham’s Academy race cars beginning in 2026, there is speculation that this engine could eventually find its way into a road-legal version of the Seven. This possibility gains traction given the recent discontinuation of the 1.6-litre Ford engine used in various models. If realized, this transition could introduce an exciting new entry-level option for enthusiasts, showcasing both racing pedigree and street-ready adaptability.

The collaboration between Caterham and Horse signifies a forward-thinking approach to automotive engineering, blending heritage with innovation. As the industry evolves towards sustainable and high-performance solutions, partnerships like these highlight the importance of adaptability and technological advancement in maintaining a competitive edge while preserving the essence of driving pleasure.
