According to Mark Ellis, Munro & Associates battery specialist, Tesla has a state of the art battery pack. Its management system is years ahead of what competitors currently offer. When we described the Obrist Mark II, their vacuum fixation technology called our attention. Why was it so revolutionary as the Austrian company described it? We spoke to Martin Graz, COO of Obrist Powertrain, and it all resumes to its cost and weight goals: both as low as possible.

As we explained, the Mark II did not have the objective to be better than the Tesla Model 3. The fact that they look similar is just a detail. The Mark II's goal is to show that the HyperHybrid system can offer a car that can run 1,500 km with 30 liters of gas or a little less with renewable fuels. It also happens to cost less than half of what the Model 3 price – in part, due to the vacuum fixation technology.

It has an important role in keeping costs down and also in improving the energy density of the pack. That is probably the most surprising part of the whole concept. Check what Graz told us.
