“We take out the combustion engine and we have a frame which uses the old points of the engine,” Timo Walden, project manager at e-Revolt and one of the company’s first investors, explained. “And so we can easily swap only the engine with the new frame and the components. And that’s why we are much faster than an individual solution. So, the frame here is a big part of our fastness”. The company says it usually takes on average around a day to complete the process, which includes stripping the old engine block out of the car and replacing it with its patented battery technology and engine frame, as well as the full digitalisation of the vehicle. Costing between €12,000 and €15,000 to complete the job, the price point may give some reassurance to many consumers who currently can’t stretch their budgets to buy a new EV.

Article too vague in that regard, but it seems such cars are allowed to transit on german roads, so assumingly they are safe to drive.
