Drive eO is an engineering company which operates from Latvia and specializes in development of electric and hybrid electric prototype vehicles for demanding applications. It was founded in 2011 to create the first ever hybrid electric rally car OSCar eO for the 2012 Dakar Rally. Driven by and, it successfully completed the rally.
The company went on to develop a number of electric racing cars for participation at the Pikes Peak International Hill Climb. In 2015, the one-megawatt eO PP03 race car driven by Rhys Millen set a new EV record and became the first ever all-electric vehicle to win the event overall.

eO PP01

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:
Drive motorFour liquid cooled YASA-750 electric motors, total peak power 400 kW / peak torque 3000 Nm
Motor controllerFour liquid cooled SEVCON electric motor controllers
Chassis controllereO master controller
Battery packeO 50 kWh custom battery pack with integrated BMS
ChargereO 80 kW off-board DC charger
Total mass1050 kg

The car was driven at the 2013 Pikes Peak International Hill Climb by Latvian and Baltic touring car champion . 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. A documentary called "" has been produced about the project and was first aired in September 2013 on LTV7 during motoring programme "Tavs auto".

eO PP02

Drive eO returned to the Pikes Peak International Hill Climb in 2014 with a race car based on a Tesla Roadster chassis. This was the first time that Tesla brand was represented at a major international motorsport event. The original chassis was retained but the entire drive train was replaced by Drive eO to validate the new components ahead of scaling them up for successive electric supercar projects. The car was again piloted by Janis Horeliks and he completed the course in 12 minutes and 57.536 seconds to rank fifth in the Electric Modified division.
