Many people feel like they don't design cars like they used to. We agree, which is exactly why we designed the Stärke Speedster. It's polarizing beauty and striking style will bring you back to the golden era of automobile design every time you grasp the wheel.


There's a number of way's to build something but there's only one way to do it right. At Stärke we sought out only those craftsman who are at the top of their trade to be a part of our team, many of whom have twenty plus years in perfecting their craft.


If you understand the Speedster and it's iconic legacy you're in a select group of very passionate people. The passion that we both share for this iconic design is what motivated us to perfect every detail of this modern masterpiece.


At Stärke, our team of career craftsman are dedicated to the highest quality standards. You'll notice our attention to detail in everything we do from our hand laid carbon fiber body panels to our hand polished, custom milled trim parts.
