This car was responsible for beating MS VII's Guinness World Record for the Longest Journey by Solar Electric Vehicle by circumnavigating the world. They traveled a total of 29,753 km after WSC 2011, and finished in December 2012.

Aerodynamics

Note: They seem to have obtained various drag coefficients depending on how these were computed.

Dynamics

They use Schwalbe Energizer S tires.

Performance

Array

They had their array encapsulated by Gochermann Solar Technology.

They use the Brusa Tracker for their MPPT. I've never heard of these, and they don't seem to be listed anymore on their website.

They also say that they have a mechanism to automatically disconnect the array when the pack is fully charged.

Note: I presume they use 8 modules, since they have 8 MPPTs.

Battery Pack

So there's actually 2 sets of numbers floating around online for the size of their battery pack (and range). This is because they had 1 pack for competing in WSC, and then increased their battery capacity for their Guinness World Record attempt.

With that being said, their WSC pack is tiny. This is because WSC didn't officially recognize cruisers until 2013's race, which meant that Bochum needed to design a Cruiser vehicle with Challenger constraints in mind.

Motors

Bochum also designs their own motors, which features an adjustable air-gap.

Motor Controllers

They use the Tritium WaveSculptor 22.

Telemetry

They use Bluetooth to the chase vehicle.
