The Lotus 27 was a Formula Junior version of the Lotus 25Formula One car for the 1963 Formula Junior season. Its body was aluminiummonocoque with steel bulkheads.[1] It was originally designed with fibreglass sides which led to flexing problems, leading to them being replaced with aluminium.
The Team Lotus cars were run by Ron Harris; and Peter Arundell won the 1963 British championship after the initial flexing problems were solved.
