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]

Based on a Tesla Roadster chasis Drive eO is returning to the Pikes Peak International Hillclimb in 2014. This will be the first competition for the Tesla marque in a major world motorsport competition. While the eO car of 2014 resembles a Tesla Roadster from the outside, its insides have been completely replaced. Drive eO [10] rear wheel drive and the prototype itself is built to validate the new components ahead of scaling them up for successive electric supercar projects, according to the eO announcements. Janis Horeliks, who piloted Drive eO's 2013 Pikes Peak entry, will also be returning to race the roadster up the 156 turn mountain course on race day,.[11][12]
