The automotive team of the School Tecnun eRacing takes stock of the work done during the first four-month period in which "they have made progress in all areas of the project", and are already focused on completing their single-seater to try to compete this summer in Formula Student, "if the pandemic situation finally allows it", as stated by team member Laura López Conde.

What have been the main developments in the first four months of the year?

During the first four months of the year, progress has been made in all areas of the project. At the technical level, the final CAD of the entire vehicle has been completed, and the manufacturing of most of the vehicle's parts has begun. At the concept level, the objectives for the season were defined at the beginning of the quarter, both at single-seater and team level. In addition, the Business Department has formalized many partnerships with our sponsors, which bring us closer and closer to our ultimate goal. Finally, we have been able to test the 2019 car twice during this four-month period, which has allowed us to gather data and information to improve the designs of the new TeR 21.

What are the technical specifications of this year's car? 

It is a single-seater with electric propulsion by means of two independent motors controlled with a Torque Vectoring logic, which allow a maximum power of up to 80 kW or 107CV, with a total capacity of the battery system of 6.5 kWh. Thanks in part to a new monocoque chassis, one of this year's major improvements, the new TeR reduces its weight by 20 kilograms, standing at a kerb weight of 275 kilograms with driver. Accompanying the new monocoque is a completely redesigned double wishbone suspension with push-type actuation, which will extract maximum performance from the new 16-inch Hoosier R25B tires. All this is accompanied by the most powerful aerodynamic package ever carried by a single-seater designed at this university.

Is the way you are organizing yourselves similar to other years?

This year, changes have been made to the departmental structure to better adapt to the team's internal management processes. From the previous organization department, two new departments have been created, the Business department (in charge of sponsor management and external communication of the team) and the Operations department (in charge of team logistics and cost and supplier management). On the other hand, the Race Engineering department has been created, with the intention of focusing our efforts even more on scoring points in the dynamic tests, and making the most of the time on the track.

What technical or material support has been provided by sponsors?

As in other years, we count on important collaborations that make the project possible. Among them, we always highlight the support of Alunid, who provides us with aluminum honeycomb for the manufacture of the car; Polistmodel, who helps us with the wooden model of the monocoque and the AIC, who supports us financially and technically. We also received a lot of support and help from companies such as Optimus3D, Gurit, Bahco, Pixel Sistemas, Vector Iberia, Irizar, Ansyso Siemens.

Have you gained any new sponsors in recent months?

Being aware of the situation that we have lived and continue to live these months, the team has not had an easy time looking for new collaborations. However, this season we have been fortunate to be able to start collaborating with many new companies such as Denatekwho supports us in the machining of the parts and Tecci, who has manufactured the plates for this year's single-seater. We will also receive this season new help from many other companies such as EFT Systems, EMRAX or Haas. We would like to take this opportunity to thank them all for their support.

What are your objectives for the second quarter?

The team has a clear objective for the second half of the year: to accumulate kilometers. Our idea is to have the prototype ready by March, which allows us 4 months of testing before competition, to accumulate a minimum of 150 kilometers with the single-seater. The kilometers will allow us to know the car in detail, which in turn will allow us to optimize it and improve it for future designs. In addition, the team intends to take advantage of the months before competition to start developing the new team for the following season, as well as the future single-seater that will replace the TeR21.

Pandemic permitting, do you plan to participate in any competitions this summer?

The team's intention is to participate in two competitions this year, one of them in Montmeló, Barcelona, and the other in Europe, which will be decided once the team knows the dates and conditions of the different competitions and we can make a decision as a team.
