This website is dedicated to building a sevenesque sports car with inspiration provided by Ron Champion's book entitled, " Build Your Own Sports Car for as Little as £250" from Haynes Publishing. To distinguish Ron's design from other sevenesque cars, Ron adopted the name "Locost" (pronounced 'low-cost') to reflect the similarity with the Lotus design while reminding us that building a sports car from the ground up can be accomplished on a minimal budget.
Today there are hundreds of builders around the world that have created, or are in the process of creating their own sevenesque sports car with nothing more than basic shop tools in their home garage. Each car develops it's own characteristics as the builder is challenged with a unique combination of budget constraints, parts availability, mechanical knowledge, and even government regulation. For those who desire an even greater challenge, the 750 series in the United Kingdom is dedicated to racing Ron Champion's Locost design. Similar creations also compete in the Sports Car Club of America's D-mod classification with great success and a healthy dose of controversy.
In addition to full CAD drawings of the "book" design to assist the Locost builder, this website contains drawings for alternative designs, an interactive 3-dimensional model of a sevenesque chassis, a comprehensive list of builders from around the world, and step-by-step documentation of a sevenesque design through the assembly process.
