It was founded in 2011 [1] to create the first ever hybrid electric rally car OSCar eO for the 2012 Dakar Rally [2].

[edit]

The car features an all wheel drive electric drivetrain with one inboard mounted direct drive motor per wheel. It is based on a tubular spaceframe chassis with bodywork derived from Aquila CR1 racing car. Drive eO gives the following vehicle specification [6]:

Drive motor Four liquid cooled YASA-750 electric motors, total peak power 400 kW / peak torque 3000 Nm
Motor controller Four liquid cooled SEVCON electric motor controllers
Chassis controller eO master controller
Battery pack eO 50 kWh custom battery pack with integrated BMS
Charger eO 80 kW off-board DC charger
Total mass 1050 kg

The car was driven at the 2013 Pikes Peak International Hill Climb by Latvian and Baltic touring car champion Jānis Horeliks [7]. The adverse weather conditions had made the track surface slippery and he went off road after losing grip in a left hand corner at the Halfway Picnic Grounds [8]. A documentary called "Uzvaras cena" has been produced about the project and was first aired in September 2013 on LTV7 during motoring programme "Tavs auto" [9].
