On 11 July 2019, a year after the premiere of Poland’s first Formula Student electric car, the AGH Racing Team introduced the second, completely new construction of this type.

This year’s racing car is the sixth design by AGH Racing. The new model features a number of modern technological solutions used mostly in power supply, suspension and electric drive systems. The new design was developed based on the extensive experience the team had gained when building the last year’s ‘Stanisław’. At all stages of the project, the car’s constructors relied on most advanced technological developments as well as simulations and tests conducted on state of the art engineering software.

The leitmotif of the new car and the team’s upcoming racing season has been set in the context of the futuristic trend of cyberpunk, combining nostalgia with the atmosphere of the 1980s. With reference to this aesthetics, the car was named ‘LEM’, in honour of the eminent Polish futurist, whose life was inextricably connected with the city of Cracow.

One of LEM’s key components is its battery consisting of 618 lithium-ion cells. Its construction was made of glass fibre in order to provide required strength and safety while ensuring that the car remains lightweight. The vehicle is powered by electric engine with permanent magnets. The combination of carefully selected dimensions with the most durable and lightweight materials such as titanium shaft and CNC-made aluminium mountings translated into top-notch quality of the design.   

Another interesting feature of the car is its innovative suspension system involving isolated damping of individual types of sprung mass motion – longitudinal and transverse tilt as well as up and down movements, which has been implemented to improve the handling of the car on the exceptionally winding tracks of Formula Student. The car features most advanced commercially-available solutions. The 3D FDM printing technology enabled printing a number of components, such as moulds for aerodynamic elements, which were used to produce required composites as well as non-flammable containers for storing charger packages. Compared to the previous release, the electronic setup has been enhanced to include temperature sensors for tyres and brake discs.

The new construction will be put to the test on the Zalazone Automotive Proving Ground during FS East Hungary event to be held from 17-21 July and also on 20-25 August on the F1 Circuit de Barcelona-Catalunya race track in Spain.
