The Abu Dhabi Autonomous Racing League (A2RL) is an innovative racing series that has the potential to revolutionize the world of motorsport. Taking place on April 27 at the Yas Marina Abu Dhabi Grand Prix venue, the first-ever A2RL event will feature eight teams competing for a prize pot of $2.25 million.
Unlike traditional racing series, A2RL utilizes cutting-edge autonomous technology. The cars that will participate in the inaugural event are Dallara-built Super Formula SF23 cars, which are currently the fastest open-wheel cars in the world, second only to Formula 1. These cars have been specifically designed to incorporate the autonomous software, known as the ‘autonomous stack,’ which includes sensors and actuators. Additionally, the chassis is constructed using sustainable bio-composite materials.
While all the cars in A2RL are identical, each team has the opportunity to code their own ‘autonomous stack.’ This coding will determine the success of each team. Stephane Timpano, CEO of ASPIRE, explains the modifications made to the SF23 racecars for A2RL: “The modifications done to the SF23 racecars used in A2RL are extensive. All race cars in A2RL use a drive-by-wire system that replicates human inputs. This system employs actuators for the steering, braking, and gear shifting, eliminating the need for a physical driver. These actuators are all controlled by the onboard computer. The next major modification is the vast array of sensor technologies that will allow the machine learning algorithms to ‘see’ and develop situational awareness – including radar, lidar, cameras, and GPS.”
Each car will be equipped with seven 360-degree cameras, which will be connected to a high-powered Neousys RGS-8805GC computer. The suspension of the SF23 is pushrod at both the front and rear, with adjustable dampers. The braking system consists of Brembo brake callipers and carbon discs.
Under the hood, the SF23 is powered by a four-cylinder turbocharged engine, the K20C1 engine, based on the 2.0 litre Honda used in Super Formula. It is paired with a six-speed 3MO gearbox. Yokohama Advan tires, commonly used in Super Formula, will be used on the SF23.
Replicating the skills and inputs of real-world drivers is a significant challenge that all eight teams must overcome in order to succeed in A2RL. The teams will need to code their AI systems to adapt to various track conditions, grip levels, g-forces, and suspension movements that drivers and race cars encounter at each circuit. This competition not only showcases groundbreaking AI technology but also highlights the potential of autonomous vehicles in improving road safety.
