The traditional Snaefell Mountain Course , the 60.725 km long track of closed roads on which the Isle of Man TT , the world's oldest and toughest motorcycle race, has been held since 1911 , was driven.

The founder of the race recognized by the Fédération Internationale de Motocyclisme was the businessman Azhar Hussein. The race was held within the TT .

The fastest of the 15 motorcycles actually raced, seven of which made it to the finish line, was the Agni X01 with driver Rob Barber with a time of 25 minutes and 53.5 seconds and an average speed of 141 km / h. This is just above the lap record of the 50 cm³ class from 1966. The current course record for the most powerful petrol engines is held by John McGuinness with an average speed of 211.754 km / h .

Second was Thomas Schönfelder from the German XXL Racing Team , third Mark Buckley from the US Team Brammo .

Attendees

19 motorcycles from 16 teams from six countries were entered.

Agni

Agni, a British - Indian team, was sponsored by the electric motor manufacturer Agni . Meanwhile, 11 kg heavy 16- kilowatt - DC motors of the designer Cedric Lynch are considered unrivaled in terms of the ratio weight / power. Two of these air-cooled DC motors with permanent magnets were built into the winning machine , a Suzuki . However, three other motorcycles with this engine broke down due to engine damage. The two Agni motors are firmly mounted on a shaft that drives the rear wheel without a gear via a chain. Agni relied on lithium polymer batteries from the manufacturer Kokam .

XXL racing

The XXL Racing Team from Kassel was founded by Thomas Schönfelder, who had already competed six times on the Isle of Man with petrol motorcycles. Thomas Schuricht, an expert in chip tuning and engine control , and high-voltage specialist Marko Werner, who had worked on the Transrapid construction in Shanghai , became partners for the motorcycle construction . The basis was an electric motor that was used in 1998 in the Audi Duo , a hybrid car developed by Audi and Siemens but discontinued . The 90 kW engine was throttled to 45 kW for the race. Technically, it was a water-cooled, brushless Siemens three-phase motor. The engine contributed by the developer at the time was installed in a Laverda . After many unsuccessful attempts to get batteries, lithium-manganese batteries from Sony were finally used, which are also used in the Twike light- weight electric car .

Brammo

The team from the US electric motorcycle manufacturer Brammo used a motor from the German electric motor manufacturer Perm for its racing machine. Brammo used lithium-cobalt dioxide accumulators developed in-house .

The split: The TTXGP as the origin of three racing series

All three partners each founded a separate racing series:

  • the founder Azhar Hussein the racing series TTXGP The eGrandPrix
  • the organizer of the Isle of Man TT, the Isle of Man Department of Economic Development, IOM TT Team on the island the TT Zero as part of the traditional Tourist Trophy Zero (emission): " The Isle of Man Government Department of Economic Development has confirmed that the groundbreaking SES TT Zero Clean Emissions Motorcycle Challenge will again take place on the Isle of Man in 2012 as part of the annual TT Races meeting. "
