Coyne Performance Engines

Coyne Performance was founded in 2015 by Matt Coyne, with a deep focus on the 2001-2006 BMW M3 platform, offering a wide range of specialized services. But Matt's journey into the world of car performance began long before the establishment of CP. His passion for BMW’s iconic E46 M3 began back in 2009, when he first purchased one, igniting a love for the platform that would evolve into a thriving business.

Over the past decade, Matt has transformed his passion into a business with a reputation for excellence. In 2015, he made the bold decision to step away from his role as a lead technician at a European specialty shop to open Coyne Performance. The demand for his expertise and his commitment to professionalism made this transition not only possible but inevitable. His technical prowess, paired with a meticulous attention to detail, has allowed him to build a brand that continues to grow, solidifying his place as an expert in the BMW performance market.

Kassel Performance is the latest chapter in Matt’s journey, expanding upon the success of Coyne Performance by reaching a broader audience— the general BMW market. With a proven track record of meticulous work on M3s, Matt is eager to extend his expertise to all BMW owners, delivering honest, precise, and top-tier performance work to help every BMW owner experience the very best of what their vehicle can offer.

At Kassel Performance, we believe in quality, passion, and precision. Matt’s commitment to perfection continues to drive the legacy of both CP and Kassel Performance, ensuring your BMW gets the care it deserves.
