AOTech specialises in providing engineering services to car manufacturers, race teams and other relevant companies, with activity divided into three fields: aerodynamic studies and development, a state-of-the-art driving simulator, and the manufacturing of composite materials. Their goal is to make the latest technologies widely available by spreading the costs of running expensive machinery between their clients, enabling aoTech to offer them bespoke high-tech services.
Guillaume Legoff - Director of AOTech
“We’ve focused on the car’s aerodynamics using both CFD and wind tunnel technologies. Working closely with Spark throughout the design and development process, while continuously conducting experiments, meant we were able to see the on-track results for ourselves. Thanks to our CFD simulations, they were able to accurately design the car, calibrate the power and size of the battery and select its optimal weight. AOTech also assisted Spark in visualising drag and downforce. The aerodynamic challenges we’ve faced are far different from those we’re used to. For example, keeping the SRT_01E’s level of drag as low as possible was much more important compared to other series. This is demonstrated in side-pod and engine cover length. We ran simulations on famous street circuits such as Pau, Macau and Monaco, excluding the long straights as they made little sense considering the battery life. The latter was always going to be a key aspect for the future of fully electric cars, so we ran further simulations to help Spark reach a sustainable solution.”
