The Jordan Honda EJ12 is Jordan’s second Formula One car to incorporate a ‘works’ Honda engine, the RA002E, which is packaged differently than its 2001 predecessor. As a consequence, the chassis rear bulkhead has been modified to suit the new engine.
The EJ12 incorporates heavy design revisions to the front of the chassis, therefore requiring a re-packaged front suspension system. New materials and production techniques have been utilised in the chassis to further reduce weight and the centre of gravity position, with the revised side-pods making the side impact structures smaller, but more efficient.
The seven speed gearbox is based on a revised version of the 2001 unit, although its internals have been re-packaged into a lower position with the casing optimised for stiffness. The car’s cooling system has further been re-configured, making it lighter.
New regulations imposed by the FIA for 2002 have made the electrical power steering system illegal, prompting the team to design a new power assisted steering system for the EJ12.
In line with current F1 design philosophy, the front and rear suspension features pushrod-operated Penske dampers, while the EJ12 utilises Brembo brake calipers carbon fibre discs. With increased competition between tyre manufacturers, Jordan has opted to continue its successful partnership with Bridgestone, working closely with the Japanese company during the winter to develop new specification tyres.
