Notes             

      There have been two eMAX vehicles. The original 2002 vehicle was essentially MAX converted from petrol to electric drive. The second, built in 2004, used the same electric drive system added to the HPV Discovery.  The canopy was strengthened  and the battery trays were moved to a position under the front cross-member for better weight distribution. In 2004 it only competed at the AIPP. It did not compete in the RACV EB in 2003 and 2004 as the rules at the time required more batteries to be carried than could be reasonably fitted to the vehicle.

      The vehicle has proven to be very fast, has set fastest laps at many outings but is a challenge for young riders to control.

Competition Record           

      2002 RACV Energy Breakthrough: Runners- up hybrid 1 open class trial and overall. The vehicle ran strongly but suffered a bad crash, bending the front cross-member. It was repaired and finished third across the line.

      2004 AIPP. Set fastest lap in top ten shoot out to take pole position of all vehicles. Winner of hybrid section which was the last year hybrids ran at the AIPP.
