IC06

IC06 was the successor to the cars built by the Imperial Racing team, which had last taken IC03 to Formula Student in 2007. It competed in Formula student in 2011 alongside IRG04 (in different classes) and 2012 (finishing 40th in class 1). It was the last internal combustion engine used (albeit biofuel) by Imperial Racing Green and was succeeded by EV2.

From the outset IC06 was designed to be as compact and lightweight as possible. The chassis was a welded steel space frame comprised of only four bulkheads, minimising overall length, whilst power comes from a lightweight V-Twin Aprilia 55RX engine. Both the exhaust and intake lengths were tuned to maximise power and torque along with a fully programmable ECU which provided the option to compromise between performance and fuel consumption.

Notable features of IC06 included a centrifugal clutch, pneumatic gear change, lightweight carbon-fibre suspension and a removable firewall for easy engine bay access.

The car had two shells, as can be seen in the images below.
