It was founded in 2011 [1] to create the first ever hybrid electric rally car OSCar eO for the 2012 Dakar Rally [2]. Driven by Māris Saukāns and Andris Dambis, it successfully completed the rally [3].
The company has also developed an all electric supercar eO PP01 for participation at the Pikes Peak International Hill Climb in 2013 [4].

eO PP01[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].
