1961 Lotus 21 Navigation
This Lotus, chassis number 918, is the second to last of approximately 15, 18/21s built and was a purpose built Formula One by UDT-Laystall, Colin Chapman, founder of Lotus, having received all ten of the factory Lotus 21s for himself. F-1 #918 was one of the first race cars to use the new HD-5 Hewland transaxle, Hewland being a new constructor partner for Laystall. The Lotus 18/21 was more than just an upgrade of the Formula Junior 18, but included several changes that were to become the standard in future cars. With a more aerodynamic body, a lay down driving position, and top linked rear suspension being some of the more recognizable changes. The 18/21 also had a stronger chassis to deal with the increased power of the Coventry Climax power. Chassis #918 was raced by the who's who of the 1961-62 racing season. Under the UDT-Laystall banner Stirling Moss won two races and was second in two other races in South Africa marking the last full year of his racing career.
